[0001] NEW ROCK INHIBITORS CROSS REFERENCE TO RELATED APPLICATIONS This application claims the benefit of U.S. Provisional Application 63 / 667,625, filed July 3, 2024, and U.S. Provisional Application 63 / 682,249 filed August 12, 2024. The entirety of these applications are hereby incorporated by reference for all purposes. FIELD OF THE INVENTION This invention provides rho-associated protein kinase (ROCK) inhibiting compounds for therapeutic applications as described further herein. BACKGROUND ROCK (Rho-associated protein kinase) is a kinase belonging to the AGC (cAMP- dependent protein kinase (PKA) / protein kinase G (PKG) / protein kinase C (PKC)) family of serine- threonine kinases and is activated by the GTP-bound form of RhoA. Two isoforms of mammalian Rho kinase, ROCK1 and ROCK2, have been described. They are approximately 160-kDa in weight proteins consisting of 1354 and 1388 amino acids, respectively, and contain an N- terminally located kinase domain, followed by a coiled-coil region containing the Rho-binding domain (RBD), a Pleckstrin homology domain (PH), and a cysteine-rich region at the C-terminus. The RBD binds exclusively to GTP-bound active RhoA and RhoC. The two ROCK isoforms share approximately 60% overall amino acid identity and approximately 90% identity within the N- terminal kinase domain. The carboxyl-terminal region comprises two cysteine-rich zinc finger- like motif domains and a split pleckstrin homology domain, which plays a role in the stabilization of the membrane binding of ROCK. (See, S. Hartmann, A. J. Ridley, and S. Lutz. “The Function of Rho-Associated Kinases ROCK1 and ROCK2 in the Pathogenesis of Cardiovascular Disease” Frontiers in Pharmacology, November 2015, Vol. 6, Art. 276; J. C. Koch, L. Tatenhorst, A.-E. Roser, K.-A. Saal, L. Tönges, P. Lingor. “ROCK inhibition in models of neurodegeneration and its potential for clinical translation” Pharmacology & Therapeutics 189 (2018) 1–21; Y. Feng, P. V. LoGrasso, O. Defert, and R. Li. “Rho Kinase (ROCK) Inhibitors and Their Therapeutic Potential” J. Med. Chem.2016, 59, 2269−2300). In its native form, ROCK is enzymatically inactive. This is caused by an auto-inhibition of the ROCK kinase domain by the carboxyl-terminal region of ROCK. The best-characterized upstream activators of ROCK are Rho-GTPase proteins RhoA and RhoC. In the activated GTP- bound state, they interact with the Rho-binding domain of ROCK and induce conformational changes that disrupt the autoinhibitory function of the carboxyl-terminal region. (J. C. Koch, L. Tatenhorst, A.-E. Roser, K.-A. Saal, L. Tönges, P. Lingor. “ROCK inhibition in models of neurodegeneration and its potential for clinical translation” Pharmacology & Therapeutics 189 (2018) 1–21). There are a large number of downstream targets that are phosphorylated by ROCK. Activation of ROCK leads to the phosphorylation of several central regulator proteins resulting in diverse cellular responses like autophagy, cell survival and apoptosis, vesicle dynamics, cytoskeleton regulation, cell growth and regeneration, as well as cell shape and motility. In response to activators of Rho, which stimulate Rho-guanine nucleotide exchange factor (GEF) and lead to the formation of active GTP-bound Rho, ROCKs mediate a broad range of cellular responses that involve the actin cytoskeleton. For example, they control assembly of the actin cytoskeleton and cell contractility by phosphorylating a variety of proteins, such as myosin light chain (MLC) phosphatase, LIM-kinases, adducin and Ezrin / Radixin / Moesin (ERM) proteins. ROCK2 can alter the sensitivity of smooth muscle cell contraction to Ca2+, since MLCK is Ca2+sensitive. ROCKs are important regulators of cellular growth, migration, metabolism and apoptosis, through control of the actin cytoskeletal assembly and cell contraction. ROCK1 expression tends to be more ubiquitous (ROCK1 messenger RNA and protein are highly expressed in the lung, liver, spleen, kidney, and testis), while ROCK2 is most highly expressed in cardiac and brain tissues. ROCKs regulate cell polarity and migration, predominantly through enhancing actomyosin contraction and focal adhesions. Increased ROCK activity is observed in tumor metastasis and overexpression of constitutively activated ROCK promotes tumor invasion. (Y. Rikitake et al. “ROCKs as therapeutic targets in cardiovascular diseases” Expert. Rev. Cardiovasc. Ther., 2005 May; 3(3): 441–451. doi:10.1586 / 14779072.3.3.441; A. V. Schofield and O. Bernard, “Rho-associated coiled-coil kinase (ROCK) signaling and disease” Crit. Rev. Biochem. Mol. Biol. 2013 Jul-Aug; 48(4): 301-16). Pharmacologic inhibitors of ROCKs, such as Y-27632, Fasudil (HA1077) and hydroxyfasudil, which target their ATP-dependent kinase domains, can inhibit both ROCK1 and ROCK2. ROCK inhibitors have been investigated for the treatment of a variety of pathological conditions including asthma, cancer, erectile dysfunction, glaucoma, insulin resistance, kidney failure, neuronal degeneration and osteoporosis. To date, three ROCK inhibitors are approved for clinical use: Fasudil for the treatment of cerebral vasospasm, Ripasudil for the treatment of glaucoma and Belumosudil for the treatment of graft versus host disease. Fasudil (an isoquinoline derivative) was shown to effectively inhibit ROCK and other kinases like PKA, PKG, PKC, and MLCK (J. C. Koch et al. “Compassionate use of the ROCK inhibitor Fasudil in three patients with amyotrophic lateral sclerosis” Front. Neurol. March 2020, Volume 11, Article 173). Fasudil has been the subject of multiple clinical trials for the treatment of amyotrophic lateral sclerosis (ALS) (Wolff, Andreas W., et al. “SAFE-ROCK: A Phase I Trial of an Oral Application of the ROCK Inhibitor Fasudil to Assess Bioavailability, Safety, and Tolerability in Healthy Participants.” CNS drugs 38.4 (2024): 291-302; Lingor, Paul, et al. “ROCK-ALS: protocol for a randomized, placebo-controlled, double-blind phase IIa trial of safety, tolerability and efficacy of the rho kinase (ROCK) inhibitor fasudil in amyotrophic lateral sclerosis.” Frontiers in neurology 10 (2019): 293). Several synthetic ROCK inhibitors identified by researchers at Scripps Research Institute based on indole, 5-azaindole, and 7-azaindole heterocyclic systems have been described in literature (S. Chowdhury et al. “Discovery and optimization of indoles and 7-azaindoles as Rho kinase (ROCK) inhibitors (part-I)” Bioorg. Med. Chem. Lett.21 (2011) 7107–7112; E. H. Sessions et al. “Discovery and optimization of indole and 7-azaindoles as Rho kinase (ROCK) inhibitors (Part-II)” Bioorg. Med. Chem. Lett. 21 (2011) 7113–7118.) Synthesis and inhibitory activity of some benzothiazole derivatives against ROCK have also been previously disclosed (Y. Yin et al. “Benzothiazoles as Rho-associated kinase (ROCK-II) inhibitors” Bioorg. Med. Chem. Lett. 19 (2009) 6686–6690.). Additional ROCK inhibitors are described in WO 2011 / 050245 which was filed by researchers at Scripps Research Institute. The ROCK inhibitory activity of these indole, azaindole and benzothiazole compounds varies significantly depending on substituents attached to the heterocyclic ring. Avicenna Biosciences, Inc. describes ROCK inhibitors and their uses in WO 2024 / 145569. Additional patent applications describing ROCK inhibitors and their uses include WO 2024 / 110851, WO 2024 / 023276, WO 2023 / 209692, WO 2023 / 139379, WO 2023 / 110700, WO 2022 / 020381, WO 2022 / 150676, WO 2022 / 042712, WO 2022 / 012409, WO 2021 / 214200, WO 2021 / 095945, WO 2020 / 177292, WO 2020 / 094111, WO 2019 / 000683, WO 2019 / 000682, WO 2018 / 130178, WO 2018 / 108156, WO 2014 / 177699, WO 2013 / 112722, WO 2011 / 050245, WO 2010 / 065907, WO 2010 / 065907, WO 2010 / 032875, WO 2009 / 155209, WO 2007 / 026920, and WO 2006 / 088088. Despite these efforts, there remains a need for new ROCK inhibiting compounds to treat disorders mediated by ROCK1 and / or ROCK2 in a subject in need thereof for example a human. SUMMARY OF THE INVENTION Compounds of the present invention and their pharmaceutically acceptable salts, uses, and manufacture are provided that inhibit a rho-associated protein kinase (ROCK).

Achieving blood brain barrier penetration is difficult. The blood brain period is a specially adapted layer of endothelial cells which guard the central nervous system (CNS) against pathogens, toxins, and xenobiotic compounds. The cells of the blood brain barrier form junctions between them which restrict passive diffusion. Even if a compound can diffuse through the cell membrane into the cytosol of the endothelial cells themselves the compound faces an array of transporter proteins ready to pump it back out into the blood stream. To reach the CNS, a compound must diffuse through the cell membrane, avoid being pumped out by transport proteins, and then diffuse across the cell membrane into the CNS. Adequate levels of blood brain barrier penetration are important for the treatment of neurodegenerative disorders. For example, blood brain barrier penetration is required to treat amyotrophic lateral sclerosis because this disease primarily affects nerve cells in the brain. In other embodiments a compound of the present invention is used to treat stroke, spinal cord injury, Alzheimer’s disease, Parkinson’s disease, traumatic brain injury, or levodopa-induced dyskinesia (LID). In certain embodiments, a method of treatment is provided comprising administering an effective amount of a compound of the present invention or a pharmaceutically acceptable salt thereof to a subject in need thereof, for example, a human, optionally in a pharmaceutically acceptable composition. For example, in certain embodiments, an effective amount of a compound of the present invention or a pharmaceutically acceptable salt thereof is administered to a human to treat a neurodegenerative disorder, for example amyotrophic lateral sclerosis (ALS), Huntington's disease (HD), or Parkinson’s disease (PD). In other embodiments, an effective amount of a compound of the present invention or a pharmaceutically acceptable salt thereof is administered to a human to treat a kidney disorder, for example diabetic nephropathy, or polycystic kidney disease. In certain embodiments, an effective amount of a compound of the present invention is used to treat ALS. For example, in certain embodiments, an effective amount of a compound of the present invention is used to treat bulbar, respiratory, flail arm, classical, pyramidal, or flail leg ALS. In certain embodiments, an effective amount of a compound of the present invention is used to treat Parkinson’s disease. For example, in certain embodiments, an effective amount of a compound of the present invention is used to treat motor-cognitive, cognitive dominant or motor dominant Parkinson’s disease. In certain embodiments, a compound of the present invention is used to treat levodopa-induced dyskinesia (LID). For example, in certain embodiments, a compound of the present invention is used to treat peak-dose dyskinesia, wearing-off / off-period dyskinesia, or diphasic dyskinesia of LID.

DETAILED DESCRIPTION OF THE INVENTION I. DEFINITIONS Compounds are described using standard nomenclature. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as is commonly understood by one of skill in the art to which this invention belongs. The terms “a” and “an” do not denote a limitation of quantity, but rather denote the presence of at least one of the referenced item. Recitation of ranges of values are merely intended to serve as a shorthand method of referring individually to each separate value falling within the range, unless otherwise indicated herein, and each separate value is incorporated into the specification as if it were individually recited herein. The endpoints of all ranges are included within the range and independently combinable. All methods described herein can be performed in a suitable order unless otherwise indicated herein or otherwise clearly contradicted by context. The use of examples, or exemplary language (e.g., “such as”), is intended merely to better illustrate the invention and does not pose a limitation on the scope of the invention unless otherwise claimed. The present invention includes a compound or its pharmaceutically acceptable salt thereof, with at least one desired isotopic substitution of an atom, at an amount above the natural abundance of the isotope, i.e., enriched. Isotopes are atoms having the same atomic number but different mass numbers, i.e., the same number of protons but a different number of neutrons. Examples of isotopes that can be incorporated into compounds of the invention include isotopes of hydrogen, carbon, nitrogen, oxygen, fluorine, chlorine and iodine such as2H,3H,11C,13C,14C,15N,17O,18O,18F,36Cl, and125I respectively. In one non-limiting embodiment, isotopically labelled compounds can be used in metabolic studies (with, for example14C), reaction kinetic studies (with, for example2H or3H), detection or imaging techniques, such as positron emission tomography (PET) or single-photon emission computed tomography (SPECT) including drug or substrate tissue distribution assays, or in radioactive treatment of patients. In particular, an18F labeled compound may be particularly desirable for PET or SPECT studies. Isotopically labeled compounds of this invention and prodrugs thereof can generally be prepared by carrying out the procedures disclosed in the schemes or in the examples and preparations described below by substituting a readily available isotopically labeled reagent for a non-isotopically labeled reagent. Isotopic substitutions, for example deuterium substitutions, can be partial or complete. Partial deuterium substitution means that at least one hydrogen is substituted with deuterium. In certain embodiments, the isotope is 90, 95 or 99% or more enriched in an isotope at any location of interest. In one non-limiting embodiment, deuterium is 90, 95 or 99% enriched at a desired location.

III. METHODS OF TREATMENT Rho-associated coiled-coil kinase (ROCK) isoforms 1 and 2 are downstream targets of GTP-bound and activated Rho GTPase proteins that phosphorylate a number of substrates involved in myosin-actin-cytoskeletal architecture, actin-filament dynamics, neurofilament, and actin-binding proteins. ROCK1 is expressed in a variety of human tissues including the heart, pancreas, lung, liver, skeletal muscle, and kidney, but is not substantially expressed in the brain (Fujisawa, K. et al. Identification of the rho-binding domain of p160ROCK, a rho-associated coiled-coil containing protein kinase. J Biol Chem.271:23022-8(1996)). ROCK2 is preferentially expressed in the brain and skeletal muscle (Nakagawa, O. et al. ROCK-I and ROCK-II, two isoforms of rho-associated coiled-coil forming protein serine / threonine kinase in mice. FEBS Lett. 395:189-93(1996)). Increased activity of ROCK2 is implicated in defects on dendritic spine structure and function in several model systems (Swanger, S.A. et al. ROCK1 and ROCK2 inhibition alters dendritic spine morphology in hippocampal neurons. Cell Logist. 5:e1133266(2015); Sellers, K.J. et al. Amyloid β synaptotoxicity is Wnt-PCP dependent and blocked by fasudil. Alzheimer’s Dement. 14:306-17(2018); Henderson et al. Pharmacologic inhibition of LIMK1 provides dendritic spine resilience against beta-amyloid. Sci Signal. 12:eaaw9318(2019)). Indeed, ROCK2 is implicated in a number of neurodegenerative and neurological disorders including Parkinson disease (PD), amyotrophic lateral sclerosis (ALS), Alzheimer disease (AD), spinal cord injury, stroke, and neuroinflammation (Weber, A.J. et al. Perspectives on ROCK2 as a Therapeutic Target for Alzheimer’s Disease. Front in Cell Neurosci. 15:636017(2021)). ROCK2 is shown to regulate several complex neuronal processes associated with neurodegenerative disorders. For example, AAV.shRNA-mediated downregulation of ROCK2 rescued dopaminergic neurons in the substantia nigra (SN) and preserves motor behavior in a 6- hydroxydopamine (6-OHDA)-induced Parkinson mouse model (Saal, K. et al. Neurobiol Dis. 73:150-62(2015)). ROCK inhibition can be used to modulate these neuronal processes. For example, in a study in mice ROCK inhibition led to decreased midbrain alpha-synuclein pathology and improved motor and cognitive function in a mouse model expressing human mutant alpha- synuclein (aSynA53T) (Tatenhorst et al. Fasudil attenuates aggregation of α-synuclein in models of Parkinson’s disease. Acta Neuropathol Commun.4:39(2016)). ROCK proteins are present in many types of nerve cells in the CNS. Excess activity of ROCK proteins in the CNS leads to oxidative stress, uncontrolled inflammation, immune abnormality, energy metabolism disorders, neuronal cell loss, reactive gliosis, and / or impaired synaptic transmission, thus promoting the development of neurodegenerative diseases. ROCK protein overexpression has been detected in the lesions of Alzheimer’s disease (AD), Parkinson’s disease (PD), and multiple sclerosis (MS), revealing that ROCK proteins are involved in the pathology of these diseases and might be important initiators of pathogenesis. Inhibition of ROCK proteins has been shown to cause several biological events, such as increased neurite outgrowth, axonal regeneration, and activation of prosurvival protein kinase B (AKT). (Q. Wang et al. “Advantages of Rho-associated kinases and their inhibitor Fasudil for the treatment of neurodegenerative diseases”, Neural Regen. Res.2022, 17(12):2623-2631.) Because of ROCK’s role in neuronal processes, its over activity or increased concentration is associated with various neurological defects. For example, increased levels of ROCK2 protein are observed in progressive stages of AD (Herskowitz et al.2013). While increased ROCK activity is observed in SOD1G93AALS mutant model mice (Gunther, R. et al. Rho Kinase Inhibition with Fasudil in the SOD1G93AMouse Model of Amyotrophic Lateral Sclerosis – Symptomatic Treatment Potential After Disease Onset. Front Pharmacol.8:17(2017)). Thus, a compound of the present invention or a pharmaceutically acceptable salt thereof can be administered in an effective amount to treat a neurological disease. Non-limiting examples of neurological diseases include amyotrophic lateral sclerosis (ALS), Parkinson’s disease (PD), Huntington's Disease (HD), Alzheimer’s disease (AD), and neurological deficiencies caused by spinal cord injuries. Based on the above-described roles of ROCK1 and ROCK2 in central nervous system disorders, methods and uses to treat subjects such as humans afflicted with such disorders are provided herein. In certain embodiments a method of treating a subject with a ROCK1 and / or ROCK2 mediated disorder is provided comprising administering an effective amount of a compound of the present invention or a pharmaceutically acceptable salt thereof to the subject. Non-limiting examples of disorders mediated by ROCK1 and / or ROCK2 are provided below. In certain aspects the compound of the present invention or a pharmaceutically acceptable salt thereof is used to treat a ROCK1 mediated disorder. In certain aspects the compound of the present invention or a pharmaceutically acceptable salt thereof is used to treat a ROCK2 mediated disorder. Specific examples of disorders that can be treated with the compounds described herein or their pharmaceutically acceptable salts are described below. Amyotrophic lateral sclerosis (ALS) Amyotrophic lateral sclerosis (ALS) is a relatively rare neurodegenerative disease that affects an estimated million individuals (Hardiman, O. et al. Amyotrophic lateral sclerosis. Nat Rev Dis Primers. 3(17071):1-19(2017)), with different risk levels geographically. ALS is characterized by degeneration of upper motor neurons and lower motor neurons that contribute to both motor and non-motor symptoms. Several subtypes of ALS have been identified including bulbar, respiratory, flail arm, classical, pyramidal, and flail leg ALS. In certain embodiments, a compound of the present invention or a pharmaceutically acceptable salt thereof is used to treat ALS. For example, in certain embodiments, a compound of the present invention or a pharmaceutically acceptable salt thereof is used to treat bulbar, respiratory, flail arm, classical, pyramidal, or flail leg ALS. The present invention includes the use of an effective amount of a compound of the present invention or a pharmaceutically acceptable salt thereof to treat a subject such as a human with ALS or a secondary condition associated with ALS. Parkinson disease (PD) Parkinson disease (PD) is the second-most common neurodegenerative disorder following Alzheimer disease, with an estimated 2 to 3 cases per 100,000 individuals worldwide (Parkinson’s Foundation. Statistics. 2022). PD is characterized by several dysregulated mechanisms and pathways which contribute to neuronal loss in the substantia nigra (SN), including alpha-synuclein proteostasis, mitochondrial function, oxidative stress, calcium homeostasis, axonal transport, and neuroinflammation (Poewe, W. et al. Parkinson disease. Nat Rev Dis Primers. 3(17013):1- 21(2017)). Intracellular alpha-synuclein aggregates are a hallmark of PD, as well as SN neuronal loss and striatal dopamine deficiency. Subjects are diagnosed with PD based on the presence of bradykinesia and other motor defects, as well as non-motor symptoms. Several subtypes of PD have been identified including motor-cognitive, cognitive dominant and motor dominant PD. There is presently no cure for PD and treatments focus on slowing the progression and / or decreasing the symptoms of PD. In certain embodiments, a compound of the present invention or a pharmaceutically acceptable salt thereof is used to treat PD. For example, in certain embodiments, a compound of the present invention or a pharmaceutically acceptable salt thereof is used to treat motor-cognitive, cognitive dominant or motor dominant PD. The present invention includes the use of an effective amount of a compound of the present invention or a pharmaceutically acceptable salt thereof to treat a subject such as a human with PD or a secondary condition associated with PD. Alzheimer disease (AD) Alzheimer disease (AD) is the most common cause of dementia affecting over 40 million people in 2016 (GBD 2016 Dementia Collaborators. Global, regional, and national burden of Alzheimer's disease and other dementias, 1990-2016: a systematic analysis for the Global Burden of Disease Study 2016. Lancet Neurol. 18(1):88-106(2019)) and is expected to increase to 150 million by 2050 worldwide. Estimation of the global prevalence of dementia in 2019 and forecasted prevalence in 2050: an analysis for the Global Burden of Disease Study 2019. Lancet Public Health. 7(2):e105-e125(2022)). AD is a neurodegenerative disorder characterized by extracellular plaques comprising amyloid beta and intracellular neurofibrillary tangles comprising tau leading to neuronal loss (Knopman, D.S. et al. Alzheimer disease. Nat Rev Dis Primers. 7(33):1-21(2021)). Subjects with AD present with cognitive impairment and dementia. Symptoms of cognitive impairment include loss in short-term memory, expressive speech, visuospatial processing, and executive functioning. AD risk factors include rare, dominantly inherited mutations in APP (encoding amyloid precursor protein), PSEN1 (encoding presenilin 1), and PSEN2 (encoding presenilin 2) causing autosomal dominant forms of AD. Much more common is the development of sporadic late-onset AD which is influenced by more common but incompletely penetrant genetic polymorphisms in genes such as APOE. In certain embodiments, a compound of the present invention or a pharmaceutically acceptable salt thereof is used to treat AD. AD treatments can be beneficial at several stages in the progression of the disease. For example, in certain embodiments, a compound of the present invention or a pharmaceutically acceptable salt thereof is used to treat a subject with no cognitive impairment but high levels of amyloid beta and / or tau biomarkers, subjective cognitive decline in the absence of impaired cognitive testing scoring, mild cognitive impairment, clinically confirmed AD, or autosomal dominant AD. The present invention includes the use of an effective amount of a compound of the present invention or a pharmaceutically acceptable salt thereof to treat a subject such as a human with AD or a secondary condition associated with AD. Spinal cord injury Spinal cord injuries can trigger complex and varied neurological effects including axon degeneration and mild to severe loss of cognitive function. In certain embodiments a compound described herein is used to treat a spinal cord injury. For example, a compound of the present invention or a pharmaceutically acceptable salt thereof may be used to promote axon regeneration and functional recovery in a subject who has had a spinal cord injury. The present invention includes the use of an effective amount of a compound of the present invention or a pharmaceutically acceptable salt thereof to treat a subject such as a human with a spinal cord injury or a secondary condition associated with a spinal cord injury. Stroke Stroke is a neurological disorder that occurs when one or more blood vessels that supply blood to the brain are blocked or rupture. The depletion of blood in the brain causes damage to the brain tissue in the area where the blood vessel previously delivered blood. There are two common categories of stroke: ischemic stroke and hemorrhagic stroke. Ischemic stroke occurs when the brain tissue is ischemic due to a decrease in the supply of blood caused by a blockage. Hemorrhagic stroke instead occurs due to hemorrhage when a blood vessel ruptures. Ischemic stroke is the most common form of stroke. When an ischemic stroke occurs, cells cannot obtain sufficient oxygen and nutrients due to the interruption of blood flow. In certain embodiments a compound described herein is used to treat a stroke. Non-limiting examples of strokes include ischemic stroke, acute ischemic stroke, thrombosis, embolism, transient ischemic attack, leukoplakia, and infarction. In other embodiments a compound herein is used to prevent a stroke or provide neuroprotection, for example acute neuroprotection. The present invention includes the use of an effective amount of a compound of the present invention or a pharmaceutically acceptable salt thereof to treat a subject such as a human who has had a stroke or a secondary condition associated with a stroke. Other Neurodegenerative Disorders In addition to ROCKs important role in the regulation of several complex neuronal processes research has identified ROCK as a regulator of reactive oxygen species (ROS). This biological function allows ROCK inhibition to modulate additional neurodegenerative disorders (Kang H. et al. Chemical Screening Identifies ROCK as a Target for Recovering Mitochondrial Function in Hutchinson-Gilford Progeria Syndrome. Aging Cell 16:541-50(2017) and Sheng W. et al. Reactive Oxygen Species from Human Astrocytes Induce Functional Impairment and Oxidative Damage. Neurochem. Res.38:2148-59(2013)). Non-limiting examples of neurodegenerative diseases including ataxia, Huntington's disease, motor neuron disease, multiple system atrophy, Creutzfeldt-Jakob disease, dementia, non- dementia cognitive impairment, and progressive supranuclear palsy. Non-limiting examples of dementia include senile dementia, cerebrovascular dementia, post-traumatic dementia, dementia caused by brain tumors, and dementia caused by chronic subdural hematoma. Additional non- limiting examples of neurodegenerative diseases including corticobasal degeneration, spinocerebellar ataxia, frontotemporal dementia and CMT2A (Charcot-Marie-Tooth disease type 2A). In certain embodiments the neurodegenerative disease is corticobasal degeneration. In certain embodiments the neurodegenerative disease is spinocerebellar ataxia. In certain embodiments the neurodegenerative disease is frontotemporal dementia. In certain embodiments the neurodegenerative disease is CMT2A (Charcot-Marie-Tooth disease type 2A). In certain aspects a compound of the present invention or a pharmaceutically acceptable salt thereof is used to reduce inflammation. For example, a compound of the present invention or a pharmaceutically acceptable salt thereof can be administered to a subject in need thereof to reduce inflammation in the brain. The present invention thus includes the use of an effective amount of a compound of the present invention or a pharmaceutically acceptable salt thereof to treat a subject such as a human with a neurodegenerative disorder such as one of those listed above or a secondary condition associated with the neurodegenerative disorder. ROCK has recently emerged as a novel therapeutic target for neurodegenerative disorders (J. C. Koch, L. Tatenhorst, A.-E. Roser, K.-A. Saal, L. Tönges, P. Lingor. “ROCK inhibition in models of neurodegeneration and its potential for clinical translation” Pharmacology & Therapeutics 189 (2018) 1–21). While ROCK1 is expressed preferentially in peripheral tissue, ROCK2 is highly expressed in the central nervous system (CNS). Axonal growth inhibitory molecules (e.g., Nogo, MAG, OMgp, ephrins, semaphorins) bind to specific extracellular receptors and signal via ROCK to trigger axonal degeneration, growth cone collapse, and impaired axonal regeneration. In non-neuronal structures, regulation of the actin cytoskeleton plasticity by ROCK also mediates vasoconstriction and vascular remodeling. Levels of ROCK increase with age and tissue of ALS patients shows increased levels of ROCK2 as well as its downstream targets LIMK1 and cofilin. Increased ROCK activity results in higher levels of phosphorylated adducin as well as activation of phosphatase and tensin homolog (PTEN) and decreased Akt activity. PTEN activation by ROCK exerts negative effects on cell growth, proliferation and metabolism. Inhibition of ROCK counteracts neuronal apoptosis and axonal degeneration and on the other hand fosters axonal regeneration and modulates microglia activation. (J. C. Koch et al. “Compassionate use of the ROCK inhibitor Fasudil in three patients with amyotrophic lateral sclerosis” Front. Neurol. March 2020, Volume 11, Article 173, doi: 10.3389 / fneur.2020.00173). Pain Disorders Pain is a subjective sensation reflecting a tissue damage and exhibits various forms. Pain is classified into somatic pain and psychogenic pain, and somatic pain is further classified into nociceptive pain and neuropathic pain. Nociceptive pain is caused by external stimulation or visceral pathology. Nociceptive pain is mainly acute, which disappears following cure of underlying disease, and plays a role as a biological signal generated by a disorder. Neuropathic pain is chronic pain caused by dysfunction of the peripheral or central nervous system and includes pain from various sources including pain due to diabetes, nerve compression and spinal cord injury. Psychogenic pain is chronic pain, which is due to mental disorder rather than physical disorder and cannot be explained by organic disorder, and includes chronic headache, abdominal pain of unknown cause and the like. Chronic pain can impart large distress to patients and thus, is an important target of treatment. Non-limiting examples of chronic pain include chronic pain associated with arthritis, diabetes, cancer and the like which requires pain treatment in addition to treatment of underlying disease. ROCK inhibitors have been shown to exert an analgesic effect on pain. In certain embodiments a compound described herein is used to treat a pain disorder. In certain aspects a compound of the present invention or a pharmaceutically acceptable salt thereof may be used to treat somatic pain. For example, a compound of the present invention or a pharmaceutically acceptable salt thereof may be used to treat nociceptive pain or neuropathic pain. In certain embodiments a compound of the present invention or a pharmaceutically acceptable salt thereof is used to treat nociceptive pain. Non-limiting examples of nociceptive pain include acute pain arising from an underlying disease. In certain embodiments a compound of the present invention or a pharmaceutically acceptable salt thereof is used to treat neuropathic pain. Non-limiting examples of neuropathic pain include chronic pain caused by diabetes, nerve compression, or a spinal cord injury. In certain aspects a compound of the present invention or a pharmaceutically acceptable salt thereof. is used to treat pain arising from arthritis, for example, osteoarthritis or rheumatoid arthritis. The present invention thus includes the use of an effective amount of a compound of the present invention or a pharmaceutically acceptable salt thereof to treat a subject such as a human with a pain disorder such as one of those listed above or a secondary condition associated with the pain disorder. Cardiovascular Diseases Studies have demonstrated that the Rho / ROCK pathway is increased in hypertensive patients. For example, increased ROCK-dependent smooth muscle contraction is observed in the aorta in the early stage of atherosclerosis. During atherosclerosis lesion formation, ROCK activity, is increased in certain areas and cell types including endothelium, periadventitial adipocytes and macrophage foam cells, supporting a role of ROCK in the ERM phosphorylation-mediated macrophage infiltration and foam cell formation. ROCK has a role in cardiac ischemia / reperfusion injuries, where blood flow is restricted or cut off and then is reintroduced into the area. A deleterious role of RhoA / ROCK signaling in ischemia / reperfusion injury has been demonstrated in several in vivo models including mouse, rat and swine. (M. Surma et al. “Rho kinase as a therapeutic target in cardiovascular disease” Future Cardiol. 2011 September; 7(5): 657–671. doi:10.2217 / fca.11.51). In certain embodiments a compound described herein is used to treat a cardiovascular disorder. Non-limiting examples of cardiovascular disorders include coronary heart disease, stroke, peripheral arterial disease, and aortic disease. The present invention thus includes the use of an effective amount of a compound of the present invention or a pharmaceutically acceptable salt thereof to treat a subject such as a human with a cardiovascular disorder such as one of those listed above or a secondary condition associated with the cardiovascular disorder. Ocular Disorders The ability of ROCK proteins to mediate smooth muscle contractions in the eye has made ROCK a target for the treatment of ocular disorders. ROCK mediates calcium sensitization and smooth muscle contraction. The Ca2+-sensitizing effect of smooth muscle constricting agents has been ascribed to ROCK-mediated phosphorylation of MYPT-I, the regulatory subunit of myosin light chain phosphatase (MLCP). MYPT-1 is used by the body to inhibit the activity of MLCP. By inhibiting MLCP ROCK activated phosphorylation of MYPT-1 results in enhanced phosphorylation of the myosin light chain and smooth muscle contraction (WO 2005 / 003101 and WO 2005 / 034866). Glaucoma is an ophthalmic disease that leads to irreversible visual impairment. Glaucoma is characterized by a progressive optic neuropathy caused in part by deleterious effects resulting from increased intraocular pressure. In healthy individuals, intraocular pressures ranges from 12 to 20 mm Hg, averaging approximately 16 mm Hg. However, in individuals suffering from primary open angle glaucoma, intraocular pressures generally rise above 22 to 30 mm Hg. In angle closure or acute glaucoma intraocular pressure can reach as high as 70 mm Hg leading to blindness within only a few days. The loss of vision can also result from statistically normal intraocular pressures in individuals with unusually pressure-sensitive eyes; a condition known as normotensive glaucoma (See, e.g., P. L. Kaufman and T. W. Mittag, “Medical Therapy Of Glaucoma” Ch.9, Sec. II (pp.9.7-9.30) In P. L. Kaufman and T. W. Mittag (eds.): Glaucoma (Vol. 7 of S. M. Podos and M. Yanoff (eds): Textbook of Ophthalmology Series). London, Mosby-Year Book Europe Ltd. (1994); A. C. Guyton, Textbook of Medical Physiology (W. B. Saunders Co., Sixth Ed.), pp. 386-89 (1981)). Open-angle glaucoma constitutes the majority of all primary glaucomas and is characterized by abnormally high resistance to fluid (aqueous humor) drainage from the eye. In the glaucomatous eye, the rate of aqueous humor production remains constant, while it is the increased resistance to outflow that is responsible for the elevated intraocular pressure. ROCK has also been implicated in the pathogeneses of vitreoretinal diseases caused by age and diabetic pathology. ROCK is involved in the ischemia response, angiogenesis, inflammation and membrane contraction, all key drivers of vitreoretinal diseases like age-related macular degeneration, diabetic retinopathy and proliferative vitreoretinopathies. (https: / / pmc.ncbi.nlm.nih.gov / articles / PMC5449758 / ). Diabetic retinopathy is a serious sight- threatening complication of diabetes. Diabetes damages small blood vessels throughout the body, including the retina. Diabetic retinopathy occurs when these tiny blood vessels leak blood and other fluids. This causes the retinal tissue to swell, resulting in cloudy or blurred vision. Diabetic retinopathy is classified into two types: non-proliferative diabetic retinopathy and proliferative diabetic retinopathy (“Diabetic retinopathy” American Optometric Association). ROCK proteins have been studied in diabetic retinopathy (Wong, T., Cheung, C., Larsen, M. et al. “Diabetic retinopathy.” Nat Rev Dis Primers 2, 16012 (2016); Durham, Jennifer T., et al. “Pericyte contractility controls endothelial cell cycle progression and sprouting: insights into angiogenic switch mechanics.” American Journal of Physiology-Cell Physiology 307.9 (2014): C878-C892; Arita, Ryoichi, et al. “Rho kinase inhibition by fasudil ameliorates diabetes-induced microvascular damage.” Diabetes 58.1 (2009): 215-226; Nakagawa, Takahiko, et al. “Abnormal angiogenesis in diabetic nephropathy.” Diabetes 58.7 (2009): 1471; Singh, Kirti, and Arshi Singh. “Rho-kinase inhibitors in ocular diseases: a translational research journey.” Journal of current glaucoma practice 17.1 (2023): 44).

Huntington's Disease (HD) Huntington's disease (HD) is a progressive brain disorder caused by a defective gene. This disease causes changes in the central area of the brain, which affect movement, mood and thinking skills. In Western populations HD has a prevalence of 10.6–13.7 individuals per 100 000 (McColgan, Peter, and Sarah J. Tabrizi. “Huntington's disease: a clinical review.” European journal of neurology 25.1 (2018): 24-34).

Polycystic Kidney Disease (PKD) Polycystic kidney disease (PKD) is a genetic disease that causes the growth of fluid-filled cysts in the kidneys. Autosomal recessive polycystic kidney disease (ARPKD) and Autosomal dominant polycystic kidney disease (ADPKD) are the two kinds of PKD. Autosomal dominant polycystic kidney disease (ADPKD) is the most common type of PKD and one of the most common genetic kidney diseases. About 9 out of every 10 people with PKD have ADPKD. It is characterized by relentless development of kidney cysts, hypertension, and eventually end-stage renal disease (ESRD). Clinical symptoms typically do not arise until adulthood. (Chebib, Fouad T., and Vicente E. Torres. “Autosomal dominant polycystic kidney disease: core curriculum 2016.” American Journal of Kidney Diseases 67.5 (2016): 792-810). In contrast to ADPKD, autosomal recessive polycystic kidney disease (ARPKD) is typically an infantile disease (Bergmann, Carsten. “ARPKD and early manifestations of ADPKD: the original polycystic kidney disease and phenocopies.” Pediatric Nephrology 30.1 (2015): 15- 30). It is a rare genetic disorder that can cause palpable kidneys, enlarged liver, respiratory failure, hypertension, or urinary tract infections (Zerres, K., et al. “Autosomal recessive polycystic kidney disease.” Journal of molecular medicine 76 (1998): 303-309.). ROCK proteins have been studied in polycystic kidney disease (PKD) (Ma, Shenghong, and Kun-Liang Guan. “Polycystic kidney disease: a Hippo connection.” Genes & Development 32.11-12 (2018): 737-739; Cai, Jing, et al. “A RhoA–YAP–c-Myc signaling axis promotes the development of polycystic kidney disease.” Genes & development 32.11-12 (2018): 781-793).

In certain embodiments Diabetic Nephropathy Diabetic nephropathy is a serious complication of type 1 diabetes and type 2 diabetes. Diabetic nephropathy develops in approximately 40% of patients who are diabetic and is the leading cause of chronic kidney disease (CKD) worldwide (Alicic, Radica Z., Michele T. Rooney, and Katherine R. Tuttle. “Diabetic kidney disease: challenges, progress, and possibilities.” Clinical journal of the American Society of Nephrology 12.12 (2017): 2032-2045). ROCK proteins have been studied in diabetic nephropathy (Matoba, Keiichiro, et al. “Rho- kinase inhibition prevents the progression of diabetic nephropathy by downregulating hypoxia- inducible factor 1α.” Kidney international 84.3 (2013): 545-554; Gojo, Atsushi, et al. “The Rho- kinase inhibitor, fasudil, attenuates diabetic nephropathy in streptozotocin-induced diabetic rats.” European journal of pharmacology 568.1-3 (2007): 242-247; Knipe, Rachel S., Andrew M. Tager, and James K. Liao. “The Rho kinases: critical mediators of multiple profibrotic processes and rational targets for new therapies for pulmonary fibrosis.” Pharmacological reviews 67.1 (2015): 103-117; Matoba, Keiichiro, et al. “ROCK inhibition may stop diabetic kidney disease.” JMA journal 3.3 (2020): 154-163; Matoba, Keiichiro, et al. “Renal ROCK activation and its pharmacological inhibition in patients with diabetes.” Frontiers in Pharmacology 12 (2021): 738121; Nath, Karl A. “Tubulointerstitial changes as a major determinant in the progression of renal damage.” American Journal of Kidney Diseases 20.1 (1992): 1-17; Matoba, Keiichiro, et al. “Rho-kinase blockade attenuates podocyte apoptosis by inhibiting the notch signaling pathway in diabetic nephropathy.” International Journal of Molecular Sciences 18.8 (2017): 1795).

The present invention includes the use of an effective amount of a compound of the present invention or a pharmaceutically acceptable salt thereof to treat a subject such as a human with diabetic nephropathy or a secondary condition associated with diabetic nephropathy. Focal Segmental Glomerulosclerosis (FSGS) Focal segmental glomerulosclerosis (FSGS) is a histological pattern of glomerular lesion that includes several completely different clinicopathological diseases that share injury within the podocyte as a primary pathophysiological feature (Shabaka, Amir, Ana Tato Ribera, and Gema Fernández-Juárez. “Focal segmental glomerulosclerosis: state-of-the-art and clinical perspective.” Nephron 144.9 (2020): 413-427). According to the etiology, FSGS lesion has been classified into primary, genetic, and secondary forms that include maladaptive, virus-associated, and medication-induced FSGS. ROCK proteins have been studied in focal segmental glomerulosclerosis (Zhu, Lei, et al. “Activation of RhoA in podocytes induces focal segmental glomerulosclerosis.” Journal of the American Society of Nephrology 22.9 (2011): 1621-1630; Matoba, Keiichiro, et al. “Deletion of podocyte Rho-associated, coiled-coil-containing protein kinase 2 protects mice from focal segmental glomerulosclerosis.” Communications Biology 7.1 (2024): 402; Asano-Matsuda, Kana, et al. “Role of Rho GTPase interacting proteins in subcellular compartments of podocytes.” International Journal of Molecular Sciences 22.7 (2021): 3656; Saleh, Mohamed A., et al. “RhoA / ROCK inhibition attenuates endothelin-1–induced glomerulopathy in the rats.” Life Sciences 323 (2023): 121687).

In certain embodiments, a compound of the present invention or a pharmaceutically acceptable salt thereof is used to treat a fibrotic disorder. Pulmonary fibrosis (fibrosis of the lungs) is lung disease that occurs when lung tissue becomes damaged and develops scars. A subtype of pulmonary fibrosis is idiopathic pulmonary fibrosis (IPF) which is a non-neoplastic pulmonary disease that is characterized by the formation of scar tissue within the lungs in the absence of any known provocation (Meltzer, Eric B., and Paul W. Noble. “Idiopathic pulmonary fibrosis.” Orphanet journal of rare diseases 3 (2008): 1-15). ROCK proteins have been studied in pulmonary fibrosis (Knipe, Rachel S., et al. “The Rho kinase isoforms ROCK1 and ROCK2 each contribute to the development of experimental pulmonary fibrosis.” American journal of respiratory cell and molecular biology 58.4 (2018): 471-481; Knipe, Rachel S., Andrew M. Tager, and James K. Liao. “The Rho kinases: critical mediators of multiple profibrotic processes and rational targets for new therapies for pulmonary fibrosis.” Pharmacological reviews 67.1 (2015): 103-117; Li, Qingfang, et al. “Inhibition of ROCK ameliorates pulmonary fibrosis by suppressing M2 macrophage polarization through phosphorylation of STAT3.” Clinical and Translational Medicine 12.10 (2022): e1036; Wu, Xinhui, et al. “Rho-kinase 1 / 2 inhibition prevents transforming growth factor-β-induced effects on pulmonary remodeling and repair.” Frontiers in pharmacology 11 (2021): 609509).

Levodopa-induced dyskinesia (LID) Levodopa is a used in the treatment of Parkinson's disease (PD), but its long-term use is complicated by motor fluctuations and dyskinesia. Different types of movement disorders are seen in levodopa-induced dyskinesia (LID) including chorea, ballism, dystonia, myoclonus, or combination of any of these movements. These dyskinesias are seen in the neck, facial muscles, jaw, tongue, hip, shoulder, trunk, and limb or may appear as involuntary flexion of toes (Pandey, Sanjay, and Prachaya Srivanitchapoom. “Levodopa-induced dyskinesia: clinical features, pathophysiology, and medical management.” Annals of Indian Academy of Neurology 20.3 (2017): 190-198). There have been studies on the involvement of ROCK in the pathophysiology of LID (Lopez‐Lopez, Andrea, et al. “Rho kinase inhibitor fasudil reduces L‐DOPA‐induced dyskinesia in a rat model of Parkinson's disease.” British Journal of Pharmacology 177.24 (2020): 5622-5641; Lopez-Lopez, Andrea, et al. “Interactions between Angiotensin Type-1 Antagonists, Statins, and ROCK Inhibitors in a Rat Model of L-DOPA-Induced Dyskinesia.” Antioxidants 12.7 (2023): 1454).

Traumatic Brain Injury (TBI) Traumatic brain injuries (TBIs) can affect people of all ages and are a major cause of death and disability, with an incidence of ∼10 million people worldwide (Blennow, Kaj, et al. “Traumatic brain injuries.” Nature reviews Disease primers 2.1 (2016): 1-19.). Traumatic brain injuries (TBIs) are clinically grouped by severity: mild, moderate and severe. Mild TBI (the least severe form) is synonymous with concussion and is typically caused by blunt non-penetrating head trauma. ROCK proteins have been studied in traumatic brain injuries (Fujita, Yuki, and Toshihide Yamashita. “Axon growth inhibition by RhoA / ROCK in the central nervous system.” Frontiers in neuroscience 8 (2014): 338; Lerouet, Dominique, Catherine Marchand‐Leroux, and Valérie C. Besson. “Neuropharmacology in traumatic brain injury: from preclinical to clinical neuroprotection?” Fundamental & clinical pharmacology 35.3 (2021): 524-538; Brabeck, Christine, et al. “Lesional expression of RhoA and RhoB following traumatic brain injury in humans.” Journal of neurotrauma 21.6 (2004): 697-706; Mulherkar, Shalaka, et al. “RhoA-ROCK inhibition reverses synaptic remodeling and motor and cognitive deficits caused by traumatic brain injury.” Scientific reports 7.1 (2017): 10689; Feng, Shi-jun, and Jian-guo Han. “Treatment of traumatic brain injury in rats by RhoA gene silencing combined with umbilical cord mesenchymal stem cell transplantation.” Chinese Journal of Tissue Engineering Research 17.1 (2013): 23.).

Benign Prostatic Hyperplasia (BPH) Benign prostatic hyperplasia (BPH) results in a benign enlargement of the prostate gland due to unregulated hyperplastic growth of the epithelial andfibromuscular tissues of the transition zone (TZ) and periurethral area. (Devlin, Conor M., Matthew S. Simms, and Norman J. Maitland. “Benign prostatic hyperplasia–what do we know?” BJU international 127.4 (2021): 389-399.) Benign prostatic hyperplasia (BPH) is a major cause of lower urinary tract symptoms (LUTS) including nocturia, urinary frequency, urgency, decreased urine flow rates, incomplete bladder emptying, and hesitancy (Laborde, Eric E., and Kevin T. McVary. “Medical management of lower urinary tract symptoms.” Reviews in urology 11. Suppl 1 (2009): S19.). ROCK proteins have been studied in benign prostatic hyperplasia (Shan, Shidong, et al. “Mechanism of RhoA regulating benign prostatic hyperplasia: RhoA-ROCK-β-catenin signaling axis and static & dynamic dual roles.” Molecular Medicine 29.1 (2023): 139; Takahashi, Ryosuke, et al. “RhoA / Rho kinase‐ mediated Ca2+sensitization in the contraction of human prostate.” Neurourology and urodynamics 26.4 (2007): 547-551; Morelli, Annamaria, et al. “BXL‐628, a vitamin D receptor agonist effective in benign prostatic hyperplasia treatment, prevents RhoA activation and inhibits RhoA / Rho kinase signaling in rat and human bladder.” The Prostate 67.3 (2007): 234-247; La Vignera, S., et al. “Endocrine control of benign prostatic hyperplasia.” Andrology 4.3 (2016): 404- 411).

Urinary Bladder Dysfunction (bladder dysfunction) Non-limiting examples of urinary bladder dysfunction include neurogenic bladder, interstitial cystitis / bladder pain syndrome, cystitis / bladder inflammation, overactive bladder, bladder fibrosis, and lower urinary tract symptoms (LUTS). Neurogenic bladder refers to a malfunctioning urinary bladder due to neurologic dysfunction or insult emanating from internal or external trauma, disease, or injury (Rackley, Raymond, S. P. Vasavada, and F. Firoozi. “Neurogenic bladder.” 2009). Interstitial cystitis / bladder pain syndrome is a condition that causes long-term pain or discomfort in the bladder and abdominal area, along with urinary frequency and urgency. Overactive bladder is a problem with bladder function that causes the sudden need to urinate. Bladder fibrosis refers to scarring and hardening of the tissue in the bladder. Lower urinary tract symptoms (LUTS) include nocturia, urinary frequency, urgency, decreased urine flow rates, incomplete bladder emptying, and hesitancy (Laborde, Eric E., and Kevin T. McVary. “Medical management of lower urinary tract symptoms.” Reviews in urology 11. Suppl 1 (2009): S19). ROCK proteins have been studied in urinary bladder dysfunctions (Oger, S., et al. “Rho-kinase inhibition relaxes detrusor from neurogenic patients.” European Urology Supplements 9.2 (2010): 112; Oudot, A., et al. “A new experimental rat model of erectile dysfunction and lower urinary tract symptoms associated with benign prostate hyperplasia: The testosterone-supplemented spontaneously hypertensive rat.” J Sex Med 7 (2010): 406-406; Peters, Stephan LM, Martina Schmidt, and Martin C.

Cancer There has been early, basic research on the role of ROCK in cancer (Ridley, A. J. “RhoA, RhoB and RhoC have different roles in cancer cell migration.” Journal of microscopy 251.3 (2013): 242-249; Barcelo, Jaume, Remi Samain, and Victoria Sanz-Moreno. “Preclinical to clinical utility of ROCK inhibitors in cancer.” Trends in Cancer 9.3 (2023): 250-263; Chin, Venessa T., et al. “Rho-associated kinase signaling and the cancer microenvironment: novel biological implications and therapeutic opportunities.” Expert reviews in molecular medicine 17 (2015): e17). For example, in certain advanced stage breast cancer models, ROCK has been shown to be overexpressed or of higher activity (Guerra, Fabiana Sélos, et al. “ROCK inhibition with Fasudil induces beta-catenin nuclear translocation and inhibits cell migration of MDA-MB 231 human breast cancer cells.” Scientific reports 7.1 (2017): 13723). Likewise, an amplification of ROCK1 and ROCK2 expression was observed in selected pancreatic cancer models. (Kim, Seohyun, et al. “Rho-kinase as a target for cancer therapy and its immunotherapeutic potential.” International journal of molecular sciences 22.23 (2021): 12916). Additional studies on ROCK protein in pancreatic cancer include the papers by Whatcott, Clifford J., et al. “Inhibition of ROCK1 kinase modulates both tumor cells and stromal fibroblasts in pancreatic cancer.” PloS one 12.8 (2017): e0183871; Mu, Ganggang, et al. “Gastrin stimulates pancreatic cancer cell directional migration by activating the Gα12 / 13–RhoA–ROCK signaling pathway.” Experimental & Molecular Medicine 50.5 (2018): 1-14; Vennin, Claire, et al. “Targeting ROCK activity to disrupt and prime pancreatic cancer for chemotherapy.” Small GTPases 11.1 (2020): 45-52; Vennin, Claire, et al. “Transient tissue priming via ROCK inhibition uncouples pancreatic cancer progression, sensitivity to chemotherapy, and metastasis.” Science translational medicine 9.384 (2017): eaai8504; and Zhu, Shuai, et al. “ASIC1 and ASIC3 contribute to acidity-induced EMT of pancreatic cancer through activating Ca2+ / RhoA pathway.” Cell death & disease 8.5 (2017): e2806-e2806. ROCK proteins have also been researched in melanoma models (Chang, Fei, et al. “ROCK inhibitor enhances the growth and migration of BRAF‐mutant skin melanoma cells.” Cancer science 109.11 (2018): 3428-3437; Teiti, Iotefa, et al. “In vivo effects in melanoma of ROCK inhibition-induced FasL overexpression.” Frontiers in oncology 5 (2015): 156; and Kaczorowski, Maciej, et al. “ROCK1 and ROCK2 are down-regulated in aggressive and advanced skin melanomas–a clinicopathological perspective.” Anticancer Research 40.4 (2020): 1931-1942). Initial studies on the role of ROCK proteins in prostate cancer have also been reported (Chen, Weihua, et al. “The role of the RhoA / Rho kinase pathway in anti-angiogenesis and its potential value in prostate cancer.” Oncology letters 8.5 (2014): 1907-1911; Steurer, Stefan, et al. “Up regulation of Rho-associated coiled-coil containing kinase1 (ROCK1) is associated with genetic instability and poor prognosis in prostate cancer.” Aging (Albany NY) 11.18 (2019): 7859; Liu, Kang, et al. “Genetic variants in RhoA and ROCK1 genes are associated with the development, progression and prognosis of prostate cancer.” Oncotarget 8.12 (2017): 19298).

Protein Kinase X (PRKX) PRKX, human protein kinase X, is an X chromosome encoded cAMP-dependent serine / threonine kinase. The cAMP-dependent protein kinases (cAPKs) play a key role in many signal transduction processes, mediating the majority of the known effects of cAMP in the eukaryotic cell. These multisubstrate enzymes regulate the activity of proteins involved in signal transduction, energy metabolism, cell proliferation, or differentiation by phosphorylation of Ser or Thr residues, which alters the biological properties of the target proteins. The human protein kinase PRKX is related to the catalytic subunit of cAMP-dependent protein kinases but is distinct from the isoforms Cα, Cβ, and Cγ. PRKX has 53.2% identity to the human Cα subunit of cAPK (PKA- Cα) in the catalytic core region. This degree of homology is much lower than the similarity of the two human isoforms Cα and Cβ (90.5% identity). PRKX mRNA is present in a variety of tissues, with the highest levels of expression in fetal and adult brain, kidney, and lung. (B. Zimmermann et al. “PRKX Is a Novel Catalytic Subunit of the cAMP-dependent Protein Kinase Regulated by the Regulatory Subunit Type I” Journal of Biological Chemistry, Vol. 274, No. 9, Issue of February 26, pp. 5370-5378, 1999.) In contrast to the ubiquitously expressed Cα subunit, PRKX is mainly active during embryonic organ development and cellular differentiation in hematopoietic lineages. It was found to be crucial for macrophage and granulocyte maturation. PRKX was shown to be involved in renal development, regulating epithelial cell migration, ureteric bud branching, and induction of glomeruli formation (M. Diskar et al. “Regulation of cAMP-dependent protein kinases: the human protein kinase X (PrKX) reveals the role of the catalytic subunit αH – αI loop” Journal of Biological Chemistry, Vol.285, No.46, pp.35910 –35918, November 12, 2010). The role of PRKX in disease pathology is not well understood. However, a recent study identified the dysregulation of PRKX expression as a possible molecular cause for Mayer– Rokitansky–Küster–Hauser (MRKH) syndrome (P. Pontecorvi et al. “Altered Expression of Candidate Genes in Mayer–Rokitansky–Küster–Hauser Syndrome May Influence Vaginal Keratinocytes Biology: A Focus on Protein Kinase X” Biology, 2021, 10, 450.). PRKX has also been indicated in the pathology of amyotrophic lateral sclerosis (ALS) (Oliverira G. et al., Early Gene Expression Changes in Skeletal Muscle from SOD1(G93A) Amyotrophic Lateral Sclerosis Animal Model). In certain embodiments a method of treating a subject with a PRKX mediated disorder is provided comprising administering an effective amount of a compound of the present invention or a pharmaceutically acceptable salt thereof to the subject. Mayer–Rokitansky–Küster–Hauser (MRKH) syndrome PRKX has been implicated in the development of Mayer–Rokitansky–Küster–Hauser (MRKH) syndrome (P. Pontecorvi et al. “Altered Expression of Candidate Genes in Mayer– Rokitansky–Küster–Hauser Syndrome May Influence Vaginal Keratinocytes Biology: A Focus on Protein Kinase X” Biology, 2021, 10, 450.). Thus, in certain embodiments a compound of the present invention or a pharmaceutically acceptable salt thereof is used to treat MRKH syndrome. The present invention thus includes the use of an effective amount of a compound of the present invention or a pharmaceutically acceptable salt thereof to treat a subject such as a human with Mayer–Rokitansky–Küster–Hauser (MRKH) syndrome or a secondary condition associated with Mayer–Rokitansky–Küster–Hauser (MRKH) syndrome. Graft-vs-Host Disease ROCK is associated as a driver in the pathogenesis of corticosteroid-refectory acute graft- vs-host disease, and ROCK1 / 2 inhibition has been shown to reduce immune activation in both the innate and adaptive immune systems. In animal models and clinical trials of acute graft-vs-host disease (aGVHD), ROCK inhibitors have demonstrated the ability to reduce alloimmune activation at a variety of cellular and molecular levels (https: / / www.nature.com / articles / s41467- 024-44703-7). The present invention thus includes the use of an effective amount of a compound of the present invention or a pharmaceutically acceptable salt thereof to treat a subject such as a human with graft-vs-host disease or a secondary condition associated with graft-vs-host disease.

Thus, the selected compound of the present invention or pharmaceutically acceptable salt thereof can be administered as a pharmaceutical composition which is suitable for generally for systemic, parenteral or topical administration. Non-limiting examples include or oral (including buccal and sub-lingual), rectal, nasal, topical, transdermal, pulmonary, parenteral injection (including intramuscular, intra-arterial, intrathecal, subcutaneous and intravenous), inhalation or spray, intra-aortal, intracranial, subdermal, intraperitoneal, subcutaneous, or by other means of administration. A typical manner of administration is oral or intravenous, using a convenient daily dosage regimen which can be adjusted according to the degree of affliction. Depending on the intended mode of administration, the pharmaceutical compositions can be in the form of solid, semi-solid or liquid dosage forms, such as, for example, tablets, suppositories, pills, capsules, powders, liquids, syrup, suspensions, creams, ointments, lotions, paste, gel, spray, aerosol, foam, or oil, injection or infusion solution, a transdermal patch, a subcutaneous patch, an inhalation formulation, in a medical device, suppository, buccal, or sublingual formulation, parenteral formulation, or an ophthalmic solution, or the like, preferably in unit dosage form suitable for single administration of a precise dosage. Some dosage forms, such as tablets and capsules, are subdivided into suitably sized unit doses containing appropriate quantities of the active components, e.g., an effective amount to achieve the desired purpose. Oral pharmaceutical compositions include an effective amount of the selected drug in combination with a pharmaceutically acceptable carrier or excipient and, in addition, can include other pharmaceutical agents, adjuvants, diluents, buffers, and the like. In certain aspects the term “carrier” applied to pharmaceutical compositions / combinations of the invention refers to a diluent, excipient, or vehicle with which an active compound is provided. A “pharmaceutically acceptable carrier” or “pharmaceutically acceptable excipient” typically means a carrier or excipient that is useful in preparing a pharmaceutical composition / combination that is generally safe, suitably non-toxic and neither biologically nor otherwise inappropriate for administration to a subject, typically a human. Pharmaceutically acceptable excipients must be of sufficiently high purity and sufficiently low toxicity to render them suitable for administration to the subject being treated. The pharmaceutically acceptable excipient can be inert or it can possess pharmaceutical benefits of its own. The amount of excipient employed in conjunction with the compound is sufficient to provide a practical quantity of material for administration per unit dose of the compound. Classes of excipients include, but are not limited to adjuvants, binders, buffering agents, coloring agents, diluents, disintegrants, emulsifiers, flavorants, gels, glidants, lubricants, preservatives, stabilizers, surfactants, solubilizer, tableting agents, wetting agents or solidifying material. Some excipients may be listed in more than one class, for example vegetable oil may be used as a lubricant in some formulations and a diluent in others. Exemplary pharmaceutically acceptable excipients include sugars, starches, celluloses, powdered tragacanth, malt, gelatin; talc, petroleum jelly, lanoline, polyethylene glycols, alcohols, transdermal enhancers and vegetable oils. Optional active agents may be included in a pharmaceutical composition, which do not substantially interfere with the activity of the compound of the present invention. Some excipients include, but are not limited, to liquids such as water, saline, glycerol, polyethylene glycol, hyaluronic acid, ethanol, and the like. The compound can be provided, for example, in the form of a solid, a liquid, spray dried material, a microparticle, nanoparticle, controlled release system, etc., as desired according to the goal of the therapy. Suitable excipients for non-liquid formulations are also known to those of skill in the art. A thorough discussion of pharmaceutically acceptable excipients and salts is available in Remington’s Pharmaceutical Sciences, 18th Edition (Easton, Pennsylvania: Mack Publishing Company, 1990). Additionally, auxiliary substances, such as wetting or emulsifying agents, biological buffering substances, surfactants, and the like, can be present in the pharmaceutical composition. A biological buffer can be any solution which is pharmacologically acceptable, and which provides the formulation with the desired pH, i.e., a pH in the physiologically acceptable range. Examples of buffer solutions include saline, phosphate buffered saline, Tris buffered saline, Hank’s buffered saline, and the like. For solid compositions, conventional nontoxic solid carriers include, for example, pharmaceutical grades of mannitol, lactose, starch, magnesium stearate, sodium saccharin, talc, cellulose, glucose, sucrose, magnesium carbonate, and the like. Liquid pharmaceutically administrable compositions can, for example, be prepared by dissolving, dispersing, and the like, an active compound as described herein and optional pharmaceutical adjuvants in an excipient, such as, for example, water, saline, aqueous dextrose, glycerol, ethanol, and the like, to thereby form a solution or suspension. If desired, the pharmaceutical composition to be administered can also contain minor amounts of nontoxic auxiliary substances such as wetting or emulsifying agents, pH buffering agents and the like, for example, sodium acetate, sorbitan monolaurate, triethanolamine sodium acetate, triethanolamine oleate, and the like. Actual methods of preparing such dosage forms are known, or will be apparent, to those skilled in this art; for example, see Remington’s Pharmaceutical Sciences, referenced above. In yet another embodiment provided is the use of permeation enhancer excipients including polymers such as: polycations (chitosan and its quaternary ammonium derivatives, poly-L- arginine, aminated gelatin); polyanions (N-carboxymethyl chitosan, poly-acrylic acid); and, thiolated polymers (carboxymethyl cellulose-cysteine, polycarbophil-cysteine, chitosan- thiobutylamidine, chitosan-thioglycolic acid, chitosan-glutathione conjugates). Tablets and capsules for oral use can include one or more commonly used carriers such as lactose and corn starch. Lubricating agents, such as magnesium stearate, are also typically added. Typically, the compositions of the disclosure can be combined with an oral, non-toxic, pharmaceutically acceptable inert excipient such as lactose, starch, sucrose, glucose, methyl cellulose, magnesium stearate, dicalcium phosphate, calcium sulfate, mannitol, sorbitol and the like. Moreover, when desired or necessary, suitable binders, lubricants, disintegrating agents, and coloring agents can also be incorporated into the mixture. Suitable binders include starch, gelatin, natural sugars such as glucose or beta-lactose, corn sweeteners, natural and synthetic gums such as acacia, tragacanth, or sodium alginate, carboxymethylcellulose, polyethylene glycol, waxes, and the like. Lubricants used in these dosage forms include sodium oleate, sodium stearate, magnesium stearate, sodium benzoate, sodium acetate, sodium chloride, and the like. Disintegrators include, without limitation, starch, methyl cellulose, agar, bentonite, xanthan gum, and the like. When liquid suspensions are used, the active agent can be combined with any oral, non- toxic, pharmaceutically acceptable inert excipient such as ethanol, glycerol, water, and the like and with emulsifying and suspending agents. If desired, flavoring, coloring and / or sweetening agents can be added as well. Other optional components for incorporation into an oral formulation herein include, but are not limited to, preservatives, suspending agents, thickening agents, and the like. For ocular delivery, the compound can be administered, as desired, for example, via intravitreal, intrastromal, intracameral, sub-tenon, sub-retinal, retro-bulbar, peribulbar, suprachoroidal, conjunctival, subconjunctival, episcleral, periocular, transscleral, retrobulbar, posterior juxtascleral, circumcorneal, or tear duct injections, or through a mucus, mucin, or a mucosal barrier, in an immediate or controlled release fashion or via an ocular device. Parenteral formulations can be prepared in conventional forms, either as liquid solutions or suspensions, solid forms suitable for solubilization or suspension in liquid prior to injection, or as emulsions. Typically, sterile injectable suspensions are formulated according to techniques known in the art using suitable excipients, dispersing or wetting agents and suspending agents. The sterile injectable formulation can also be a sterile injectable solution or a suspension in an acceptably nontoxic parenterally acceptable diluent or solvent. Among the acceptable vehicles and solvents that can be employed are water, Ringer’s solution and isotonic sodium chloride solution. In addition, sterile, fixed oils, fatty esters or polyols are conventionally employed as solvents or suspending media. In addition, parenteral administration can involve the use of a slow release or sustained release system such that a constant level of dosage is maintained. Parenteral administration includes intraarticular, intravenous, intramuscular, intradermal, intraperitoneal, and subcutaneous routes, and include aqueous and non-aqueous, isotonic sterile injection solutions, which can contain antioxidants, buffers, bacteriostats, and solutes that render the formulation isotonic with the blood of the intended recipient, and aqueous and non-aqueous sterile suspensions that can include suspending agents, solubilizers, thickening agents, stabilizers, and preservatives. Administration via certain parenteral routes can involve introducing the formulations of the disclosure into the body of a subject through a needle or a catheter, propelled by a sterile syringe or some other mechanical device such as a continuous infusion system. A formulation provided by the disclosure can be administered using a syringe, injector, pump, or any other device recognized in the art for parenteral administration. Preparations according to the disclosure for parenteral administration include sterile aqueous or non-aqueous solutions, suspensions, or emulsions. Examples of non-aqueous solvents or vehicles are propylene glycol, polyethylene glycol, vegetable oils, such as olive oil and corn oil, gelatin, and injectable organic esters such as ethyl oleate. Such dosage forms can also contain adjuvants such as preserving, wetting, emulsifying, and dispersing agents. They can be sterilized by, for example, filtration through a bacteria retaining filter, by incorporating sterilizing agents into the compositions, by irradiating the compositions, or by heating the compositions. They can also be manufactured using sterile water, or some other sterile injectable medium, immediately before use. Sterile injectable solutions are prepared by incorporating one or more of the compounds of the disclosure in the required amount in the appropriate solvent with various of the other ingredients enumerated above, as required, followed by filtered sterilization. Generally, dispersions are prepared by incorporating the various sterilized active ingredients into a sterile vehicle which contains the basic dispersion medium and the required other ingredients from those enumerated above. In the case of sterile powders for the preparation of sterile injectable solutions, typical methods of preparation are vacuum-drying and freeze-drying techniques which yield a powder of the active ingredient plus any additional desired ingredient from a previously sterile- filtered solution thereof. Thus, for example, a parenteral composition suitable for administration by injection is prepared by stirring 1.5% by weight of active ingredient in 10% by volume propylene glycol and water. The solution is made isotonic with sodium chloride and sterilized. Alternatively, the pharmaceutical compositions of the disclosure can be administered in the form of suppositories for rectal administration. These can be prepared by mixing the agent with a suitable nonirritating excipient which is solid at room temperature but liquid at the rectal temperature and therefore will melt in the rectum to release the drug. Such materials include cocoa butter, beeswax and polyethylene glycols. The pharmaceutical compositions of the disclosure can also be administered by nasal aerosol or inhalation. Such compositions are prepared according to techniques well-known in the art of pharmaceutical formulation and can be prepared as solutions in saline, employing benzyl alcohol or other suitable preservatives, absorption promoters to enhance bioavailability, propellants such as fluorocarbons or nitrogen, and / or other conventional solubilizing or dispersing agents. Formulations for buccal administration include tablets, lozenges, gels and the like. Alternatively, buccal administration can be affected using a transmucosal delivery system as known to those skilled in the art. The compounds of the disclosure can also be delivered through the skin or mucosal tissue using conventional transdermal drug delivery systems, i.e., transdermal “patches” wherein the agent is typically contained within a laminated structure that serves as a drug delivery device to be affixed to the body surface. In such a structure, the drug composition is typically contained in a layer, or “reservoir,” underlying an upper backing layer. The laminated device can contain a single reservoir, or it can contain multiple reservoirs. In certain embodiments, the reservoir comprises a polymeric matrix of a pharmaceutically acceptable contact adhesive material that serves to affix the system to the skin during drug delivery. Examples of suitable skin contact adhesive materials include, but are not limited to, polyethylenes, polysiloxanes, polyisobutylenes, polyacrylates, polyurethanes, and the like. V.
