Abstract
Description
[Technical Field]
[0001] (Field) Provided herein are novel bis-octahydrophenanthrenecarboxamides and and protein conjugates thereof, as well as the bis-octahydrophenanthrene carboxylate Various diseases, disorders, and It is a method for treating a condition. [Background technology]
[0002] (background) Antibody-drug conjugates (ADCs) are bioactive small molecule drugs linked to antibodies. ADCs are antibodies that combine the target specificity of small molecule drugs with the mode of action and efficacy of small molecule drugs. Therapeutic benefits have been confirmed in the treatment of cancer, which is the primary focus of ongoing trials. ADCETRIS® (brentuximab vedotin) and KADCYLA® (ad- Rastuzumab emtansine is one of two ADCs approved for the treatment of certain types of cancer. At least 40 ADCs are currently in clinical development.
[0003] Liver X receptors (LXRs) are involved in cholesterol, lipid, and glucose homeostasis, inflammation, and LXRα and LXR are ligand-dependent transcription factors that regulate the expression of genes involved in innate immunity. LXRα is highly expressed in the liver, intestine, adipose tissue, and differentiated macrophages. LXRs are expressed as (i) cholesterol transporters, e.g. , stimulates the expression of ABCA1 and ABCG1, both of which mediate cellular cholesterol efflux and (ii) negatively affecting macrophage inflammatory gene expression through the suppression of NF-kB activation. LXRs have a variety of biological functions, including regulating atherosclerosis, Proliferative disorders, neurodegenerative disorders, and inflammation have also been implicated. These include bladder cancer, lung cancer, oral squamous cell carcinoma, and prostate cancer (Pencheva et al., 200 4; Wu et al., 2015; Kaneko et al., 2015; Chuu et al., 2006). Neurodegenerative disorders include: Alzheimer's disease and myelin gene expression (Terwel et al., 2011; Sandoval- Hernandez et al., 2016; Meffre et al., 2014). Inflammation includes inflammatory bowel disease, ulcerative colitis, and Enteritis, Crohn's disease, and arthritis (Anderson et al., 2011; Huang et al., 201 5; Cui et al., 2012). Macrophage LXRs are known to contain anti-atherogenic activity. LXR agonists have been shown to (i) inhibit the initiation of atherosclerosis and slow its progression; (ii) attenuating atherosclerosis and improving established atherosclerotic lesions; and (iii) can reduce lesional macrophage content by apoptosis. It is believed that
[0004] The therapeutic efficacy of small molecule LXR modulators may be enhanced by, for example, undesired modulation of LXRs in non-target cells. Regulation of LXRs in non-target cells is limited by their limited activity and / or low bioavailability. However, poor bioavailability can lead to undesirable side effects, including but not limited to: However, this appears to be due to a number of reasons, including low solubility, which exacerbates the inadequate therapeutic window of treatment. If ADCs containing LXR modulators are developed, target-specific LXR regulation will become possible. This would avoid side effects due to off-target regulation of LXR. Furthermore, such ADCs may offer benefits such as improved modulation of biological targets, increased bioavailability, and Therefore, small molecule ADCs of LXR modulators may be useful. There is a continuing need for effective treatment of, for example, metabolic disorders. Summary of the Invention
