Abstract
Description
[0001] The applicant filed a PCT application PCT / US2016 / 046599 entitled “Pentazamacrocyclic complexes with oral bioavailability” on August 11, 2016. The PCT application entered the Chinese national phase on April 9, 2018 with application number 201680058867.X. This application is a divisional application of the Chinese application. Technical Field
[0002] The present disclosure generally relates to transition metal pentaaza 15-membered macrocyclic ring complexes having improved properties including significant oral bioavailability. Background Art
[0003] Transition metal pentaaza 15-membered macrocyclic ring complexes having a macrocyclic ring system corresponding to Formula A have been shown to be effective in multiple animal and cell models of human disease, as well as in the treatment of disorders afflicting human patients.
[0004]
[0005] For example, in a rodent model of colitis, one such compound, GC4403, was reported to significantly reduce colonic damage in rats subjected to an experimental model of colitis when administered by intraperitoneal (ip) injection (see Cuzzocrea et al., Europ. J. Pharmacol., 432, 79-89 (2001)).
[0006]
[0007] GC4403 administered ip has also been reported to attenuate radiation damage produced in a clinically relevant hamster model of acute, radiation-induced oral mucositis (Murphy et al., Clin. Can. Res., 14 (13), 4292 (2008)) and in total lethal body irradiation of adult mice (Thompson et al., Free Radical Res., 44 (5), 529-40 (2010)). Similarly, another such compound, GC4419, administered ip, has been shown to attenuate VEGFr inhibitor-induced lung disease in a rat model (Tuder, et al., Am. J. Respir. Cell Mol. Biol., 29, 88-97 (2003)) and to increase the antitumor activity of antimetabolites and antimitotics in a mouse cancer model (see, e.g., WO2009 / 143454). In addition, another such compound, GC4401, administered ip, has been shown to provide protective effects in animal models of septic shock (S. Cuzzocrea et al., Crit. Care Med., 32(1), 157 (2004) and pancreatitis (S. Cuzzocrea, et al., Shock, 22(3), 254-61 (2004)).
[0008]
[0009] Some of these compounds have also been shown to have potent anti-inflammatory activity in vivo and prevent oxidative damage. For example, it has been reported that GC4403 administered via ip can inhibit inflammation in rat inflammation models (Salvemini, et al., Science, 286, 304 (1999)), and prevent arthritis in rat models of collagen-induced arthritis (Salvemini et al., Arthritis & Rheumatism, 44 (12), 2009-2021 (2001)). Thereafter, it has been reported that these compounds have analgesic activity and reduce inflammation and edema in rat foot carrageenan hyperalgesia models, see, e.g., U.S. Patent No. 6,180,620.
[0010] This class of compounds has also been shown to be safe and effective in the prevention and treatment of diseases in human subjects. For example, GC4419 administered by intravenous (iv) infusion has been shown to reduce oral mucositis in patients with head and neck cancer undergoing chemoradiotherapy (Anderson, C., Phase 1 Trial of Superoxide Dismutase (SOD) Mimetic GC4419 to Reduce Chemoradiotherapy (CRT)-Induced Mucositis (OM) in Patients (pts) with Mouth or Oropharyngeal Carcinoma (OCC), Oral Mucositis Research Workshop, MASCC / ISOO Annual Meeting on Supportive Care in Cancer, Copenhagen, Denmark (June 25, 2015)).
[0011] In each of these compounds comprising a five-aza 15-membered macrocyclic ring of formula A, the five nitrogens contained in the macrocyclic ring each form a coordinated covalent bond with manganese (or other transition metal coordinated by the macrocyclic ring) at the center of the molecule. In addition, manganese (or other appropriate transition metal coordinated to the macrocyclic ring) forms a coordinated covalent bond with an "axial ligand" in a position perpendicular to the macrocyclic ring in a general plane. Such coordinated covalent bonds are characterized in that the "free" electron pair available on the ligand forms a bond to the transition metal via the donation and sharing of the electron pair, thereby forming a two-electron bond between the metal and the donor atom of the ligand (Cotton, FA & G. Wilkinson, Advanced Inorganic Chemistry, Chapter 5, "Coordination Compounds", 2nd Revised Edition, Interscience Publishers, Page 139 (1966); IUPAC Gold Book, online version http: / / goldbook.iupac.org / C01329.html). The coordinate covalency of the bonds between manganese (or other such appropriate transition metal) and the five macrocyclic ring nitrogens and between manganese (or other such transition metal) and each of the two chloro axial ligands is demonstrated, for example, by GC4403 ( Fig.11 ) and GC4419( Fig.12 )'s "single crystal" X-ray crystal structure was confirmed.
[0012] Coordination compounds are contrasted with ionic compounds (e.g., salts) in which, in the solid state, the forces between anions and cations are strictly Coulomb electrostatic attractions between ions of opposite charge. Thus, in salts, discrete cations and anions provide the forces that maintain the solid structure; such as chloride and sodium ions in typical salts such as sodium chloride (Cotton, FA & G. Wilkinson, Advanced Inorganic Chemistry, Chapter 5, "The Nature of Ionic Substances", 2nd Revised Edition, Interscience Publishers, pp. 35-36, 45-49 (1966).
[0013] Although pentaaza 15-membered macrocyclic ring complexes have been disclosed in the literature for a variety of indications, the complexes disclosed to date have limited oral availability (substantially less than 5% when administered as an aqueous solution, with slightly higher but still insufficient bioavailability when administered in an appropriate oil-based formulation; see, e.g., Table 1). Typically, drug absorption from the gastrointestinal tract occurs via passive uptake, so that absorption is favored when the drug is in a non-ionic (neutral) and lipophilic form. See, e.g., Goodman & Gilman's: The Pharmacological Basis of Therapeutics, Ninth Edition, pp. 5-9 (1996). Without wishing to be bound by any particular theory, this is currently believed to be the case for this class of compounds, as exemplified by GC4419, in which both axial ligands are chlorine moieties, forming a coordinate covalent bond to the manganese and a neutral complex results:
[0014]
[0015] It is also understood that good water solubility can contribute to the uptake rate of the drug and the overall bioavailability (Goodman & Gilman's: The Pharmacological Basis of Therapeutics, 9th edition, page 5 (1996)). GC4419 and its structural analogs are relatively soluble in water, however, they cannot maintain a neutral non-ionic form in water. Instead, when dissolved in water, the coordinate covalent bonds are cleaved, and the aqueous axial ligand replaces one or more chloro axial ligands, thereby generating a monocationic or dicationic complex, as shown in Scheme 1, where the cationic compound is expected to be less able to cross the intestinal barrier than the neutral complex.
[0016]
[0017] Thus, in various aspects of the present disclosure, transition metal complexes of pentaazamacrocyclic ligands comprising a 15-membered macrocyclic ring of formula A are provided that can be administered to a subject via oral and other routes of administration to obtain high systemic levels of the drug, including by oral administration. In a currently preferred embodiment, the transition metal is manganese. Summary of the invention

[0124] Details
[0125] Aspects of the present disclosure include novel transition metal complexes of pentaaza macrocycles that also have axial ligands that have the ability to be converted in the circulation to the same species that similar bis-chloro axial ligand complexes are converted in the circulation. The compounds or complexes described herein thus have similar therapeutic efficacy to their bis-chloro analogs, but are significantly more versatile with respect to routes of administration. In other words, the compounds of the present disclosure have enhanced oral bioavailability relative to their bis-chloro analogs, and in some embodiments, also have other advantageous properties selected from one or more of the following: increased intestinal permeability, solubility in aqueous and / or oil-based dosage formulations, ease of manufacture, and / or stability.
[0126] Thus, the present disclosure relates to 15-membered complexes of a pentaaza macrocycle and Mn(II) (or other transition metal), wherein the non-macrocyclic ring ligand (i.e., the axial ligand) covalently bonded to the manganese(II) (or other transition metal) is selected from the group of moieties that yield complexes with improved versatility with respect to routes of administration (including oral administration) relative to, for example, known bis-chloro complexes. In certain embodiments, for example, the complexes described herein exhibit increased uptake across the intestinal wall, but are still able to lose one or more axial ligands in exchange for water to produce materials in the circulation similar to those obtained with the bis-chloro complex shown in Scheme 1 above. In these and / or other embodiments, for example, the complexes may also exhibit improved solubility in oil- or water-based (or other) solvents compared to the bis-chloro complex.

[0243] As described above, the second aspect of the present disclosure relates to unit dose formulations and pharmaceutical compositions, which include compounds described herein, usually with a pharmaceutically acceptable carrier or excipient, and optionally in combination with another one or more pharmaceutically active compounds. The pharmaceutical composition includes a five aza macrocyclic ring complex corresponding to formula (I) (or any embodiment thereof or other compounds described herein, such as any compound listed in Table I of the Examples section), and the complex is usually formulated into a pharmaceutical dosage form, optionally in combination with a pharmaceutically acceptable carrier, additive or excipient. In one embodiment, for example, the pharmaceutical composition includes a compound of formula (I) (or any embodiment thereof or other compounds described herein, such as any compound listed in Table I of the Examples section) and a pharmaceutically acceptable carrier or excipient. Unit dose formulations and pharmaceutical compositions according to the present disclosure can be used, for example, to treat various cardiovascular disorders, cerebrovascular disorders, skin disorders, fibrotic disorders, gastrointestinal disorders, immune disorders, inflammatory disorders, metabolic disorders, neurological disorders, ophthalmic disorders, pulmonary disorders, infectious disorders, tissue damage and combinations thereof. Specific diseases and conditions include fibrosis, inflammatory diseases and conditions (including, for example, inflammatory bowel disease, rheumatoid arthritis, asthma, COPD, pancreatitis, etc.), dermatitis, psoriasis, etc., as well as for protecting tissue from damage caused by cancer treatment or other exposure to radiation, as discussed in further detail below.
[0244] The preparation containing the compound can be in the form of a solid, semi-solid, lyophilized powder or liquid dosage form, such as, for example, an aerosol, capsule, cream, emulsion, foam, gel / jelly, injection, lotion, ointment, paste, powder, soap, solution, spray, suppository, suspension, sustained release formulation, tablet, tincture, transdermal patch, etc., preferably in a unit dosage form suitable for simple administration of precise dosage. If formulated as a fixed dose, such pharmaceutical compositions or formulation products preferably use compounds within certain dosage ranges. Depending on the intended mode of administration, therefore, in some embodiments, the composition can be in a solid, semi-solid or liquid dosage form, such as, for example, injection, tablet, pill, timed release capsule, elixir, tincture, emulsion, syrup, liquid, suspension, etc., sometimes in a unit dose and consistent with conventional pharmaceutical practice. Similarly, in some embodiments, they can also be administered via intravenous (bolus and infusion), intraperitoneal, subcutaneous, local or intramuscular routes or other routes described herein, all of which are used in forms well known to those skilled in the pharmaceutical field.
[0245] One specific embodiment of the present disclosure is directed to a unit dose formulation comprising a compound corresponding to Formula (I) (or any embodiment thereof or other compounds described herein, such as any compound listed in Table 1 of the Examples section) in an oral dosage form as described herein. Another specific embodiment of the present disclosure is directed to a unit dose formulation comprising a compound corresponding to Formula (I) (or any embodiment thereof or other compounds described herein, such as any compound listed in Table 1 of the Examples section) in a parenteral dosage form as described herein.
[0246] For oral and non-oral dosage formulations, the above-described compound (or any embodiment thereof or other compounds described herein, such as any compound listed in Table I of the Examples section) can be dispersed in a pharmaceutically acceptable carrier before administration to a mammal. A carrier, also known in the art as an excipient, vehicle, auxiliary agent, adjuvant or diluent, is generally a pharmaceutically inert substance that imparts a suitable consistency or form to the composition and does not reduce the efficacy of the compound. A carrier is generally considered to be "pharmaceutically or pharmacologically acceptable" if it does not produce unacceptable adverse reactions, allergic reactions or other adverse reactions when administered to a mammal, particularly a human.
[0247] The selection of pharmaceutically acceptable carriers will also partially vary with the route of administration. Generally, compositions as described herein can be formulated for any route of administration, as long as the blood circulation system can be used through this route and according to the conventional route of administration of components (such as compounds). For example, suitable routes of administration include but are not limited to oral, parenteral (such as intravenous, intraarterial, subcutaneous, intramuscular, intraorbital, intracapsular, intraspinal, intraperitoneal or intrasternal), local (nasal, transdermal, buccal, eye), intravesical, intrathecal, intestinal, lung, lymphatic, intracavitary, vaginal, rectal, transurethral, intradermal, intraocular, ear, breast, in situ, intratracheal, intralesional, transdermal, endoscope, transmucosal, sublingual and intestinal administration. In a particularly preferred embodiment, the compound (or a pharmaceutical composition or unit dose formulation comprising the compound) (such as those corresponding to formula (I) (or any embodiment thereof or other compounds described herein, such as any compound and / or preparation listed in Table I of the Examples section) is formulated for oral administration.
[0248] Pharmaceutically acceptable carriers for use in combination with the compounds and compositions of the present disclosure are well known to those of ordinary skill in the art and are selected based on a number of factors: the specific compound or compounds and agents used and its / their concentration, stability, and expected bioavailability; safety; the subject, its age, weight, and general condition; and the route of administration.
[0249] Suitable components (e.g., carriers and / or excipients) for formulating solid or semisolid dosage forms such as tablets, gelatin capsules, or gels / suspensions may include, for example, diluents (such as water, glycerides, or mixtures thereof, corn oil, olive oil, sunflower oil, safflower oil, lactose, dextrose, sucrose, mannitol, sorbitol, cellulose, sodium, saccharin, glucose and / or glycine); lubricants (such as silicon dioxide, talc, its magnesium or calcium salts, sodium oleate, sodium stearate, magnesium stearate, sodium benzoate, sodium acetate, sodium chloride and / or polyethylene glycol); binders (such as magnesium aluminum silicate, starch paste, gelatin, tragacanth, methylcellulose, sodium carboxymethylcellulose, magnesium carbonate, natural sugars such as glucose or β-lactose, corn sweeteners, natural and synthetic gums such as acacia, tragacanth or sodium alginate, waxes and / or polyvinyl pyrrolidone); disintegrants (such as starch; , agar, methylcellulose, bentonite, xanthan gum or effervescent mixture; absorbent; colorant, flavoring and / or sweetener; and combination thereof. Methods for preparing such solid and semisolid dosage forms using active pharmaceutical ingredients and other components are well known in the art. For example, a composition in liquid, semisolid or paste form can be filled into a hard gelatin or soft gelatin capsule using an appropriate filling machine. Alternatively, the composition can also be extruded, sprayed, granulated or coated onto a matrix to form a powder, granule or bead, which can be further encapsulated or tableted with or without the addition of an appropriate curing agent or adhesive. This method also allows the production of a "fusion mixture", "solid solution" or "eutectic mixture".

The buffer can provide a suitable buffering capacity within the range of pH 7-8.5 or pH 7.8 or so, or within the range of pH 7.3-8. The buffer is preferably chemically inert and physiologically and pharmaceutically acceptable. Exemplary buffers include phosphate-based buffers, carbonate-based buffers, tris-based buffers, amino acid-based buffers (e.g., arginine, lysine, and other natural amino acids), and citrate-based buffers. Carbonate buffers (such as sodium carbonate or calcium carbonate or sodium bicarbonate or calcium bicarbonate buffers) may be particularly useful in certain embodiments because of their plentiful supply, strong buffering capacity, and compatibility. A particularly preferred buffer is sodium bicarbonate. In a preferred embodiment, for example, the pharmaceutically acceptable carrier comprises a buffered saline solution; more preferably, in this embodiment, the buffered saline solution is a bicarbonate-buffered saline solution.

[0404] Example 1
[0405] introduction
[0406] The compounds were screened for oral bioavailability by injecting the formulated prodrugs directly into the duodenum of minipig test subjects (intraduodenal or id administration), thus bypassing the acidic environment of the stomach and thereby eliminating potentially misleading oral bioavailability results that could result from alterations in the test drug in the acidic environment of the stomach.
[0407] The Gottingen minipig was chosen as the test model species for evaluating oral bioavailability because 1) minipigs (and suis in general) are known to mimic the physiology and pharmacology of the human intestine, particularly with respect to drug absorption; 1 and 2) previous studies using GC4403 (the enantiomer of GC4419) in Göttingen minipigs demonstrated oral bioavailability consistent with clinical experience in human studies.
[0408] Studies were conducted at Xenometrics LLC (Stillwell, KS) and id bioavailability was determined using various axial ligand derivative complexes of GC4419, GC4444, GC4403 and GC4401. In each case, the parent compounds (GC4419, GC4403, GC4444 and GC4401) with their chloro axial ligands were administered by the intravenous (iv) route as a reference for calculating 100% bioavailability as measured by AUC 0->24h (Area under the curve from 0 to 24 h (ng-hr / mL)) was measured. Calculation of the oral bioavailability % of a formulation of compound administered id required comparison with the AUC via the iv route 0->24h The AUC of this pathway is calculated 0->24h The oral bioavailability % was then calculated via intestinal absorption of the test article drug complex using the following formula:
[0409] Oral bioavailability % = AUC 0->24h (id) x (1 / dose (mg / kg)) ÷ AUC 0->24h (iv)*
[0410] *Where the iv dose was 1 mg of the test article drug per kg body weight of the minipig, and the id dose was 10 mg of the test article drug per kg body weight of the minipig.
[0411] All Xenometrics facilities are fully accredited by the Association for Assessment & Accreditation of Laboratory Animals (AAALAC). All experiments and animal care were performed within the strict guidelines established and implemented by the Xenometrics Institutional Animal Care and Use Committee.
[0412] method
[0413] Male Gottingen miniature pigs (4-5 months old, 9-12 kg body weight) were purchased from Marshall BioResources and housed in Xenometrics. After adapting for at least 14 days, each animal was surgically implanted with an intraduodenal (id) cannula using adequate anesthesia via abdominal surgery. A reusable accessible sleeve was placed externally at the distal end (see surgical details below). During a recovery period of at least 2 weeks, miniature pigs were handled daily to adapt them to the test procedures, i.e., id dosing and blood sampling. For each experiment, each miniature pig received a test article drug dissolved or suspended in an excipient vehicle. Miniature pigs do not need to restrict dosing. All dosing experiments were conducted in fasted animals. Food was removed from miniature pigs 16 hours before dosing. Miniature pigs had free access to water. Miniature pigs were allowed to obtain food 6 hours after dosing. The test article was administered via the id cannula as a bolus injection (about 1 minute) at a dose of 10 mg / kg of the parent drug in 0.1 mL / kg vehicle (such as 1.5 mL in a 15 kg miniature pig). The actual amount of total test article drug administered varies with the chemical formula weight of the prodrug. After administration of the test article, the cannula is flushed with an equal volume of excipient vehicle. Approximately 6 hours later, the cannula is flushed with corn oil. Approximately 24 hours after administration, the catheter is flushed with sterile saline solution and capped. At 0.25, 0.5, 1, 2, 4, 8, 24 and 48 hours post-injection, 2 mL blood samples were collected by cranial vena cava puncture (4 mL sodium heparin Vacutainer, 20 g 1.5" needle) after swabbing the skin surface with ethanol. Minipigs were placed in a sling in a recumbent position without anesthesia to collect blood samples. Minipigs were never used for experiments more than once every 7 days. Blood samples were kept on ice until processed to obtain plasma. Blood samples were centrifuged at 1200 x g for 10 minutes at 4°C, and plasma samples were transferred to 96-well plate tubes, capped and stored at -20°C until sent on dry ice to the analytical laboratory for measurement of drug concentrations in plasma. The concentration of the parent manganese pentaazamacrocyclic complex (independent of the composition of the axial ligand) in plasma was measured using a validated HPLC / MS / MS method, which was linear between 50 ng / mL and 20,000 ng / mL.
[0414] Xenometrics surgical procedure for oroduodenal catheterization in suis: surgical preparation to test the system.
[0415] Animal preparation
[0416] Pigs were fasted overnight before surgery and premedicated and induced according to the schedule of drugs and dosage charts. An endotracheal tube was inserted and general anesthesia was maintained with isoflurane delivered in oxygen via a precision vaporizer and a rebreathing anesthesia circuit. LRS (Lactate-Ringers Solution) was given via a peripheral catheter at approximately 100 mL / hour during surgery. Surgery was performed in a designated operating room, and aseptic techniques were followed throughout the entire surgical procedure.
[0417] VAP placement
[0418] The area on the right dorsal chest was shaved and prepared with chlorhexidine scrubs and solutions.
[0419] A midline laparotomy is performed, the duodenum is isolated and cannulated according to the description listed below, and externalized at a site along the dorsal thorax. The externalized cannula is then connected to a separate access port (VAP) and implanted subcutaneously using appropriate non-absorbable sutures. The open incision is appropriately closed to ensure that dead space is removed and the skin is closed with absorbable sutures. The peritoneum and muscle layers of the laparotomy are juxtaposed in an interrupted pattern with absorbable sutures of appropriate size. Subcutaneous tissue will be juxtaposed with absorbable sutures. The skin is closed with absorbable subcutaneous sutures.
[0420] Duodenal cannulation using a vascular access port (VAP)
[0421] The area on the ventral abdomen was shaved and prepped with chlorhexidine scrubs and solutions.
[0422] The burp valve catheter (Burp valve catheter) (Access Technologies, Chicago IL) with a 5mm Dacron disk attached 1cm from the tip is used to cannulate the duodenum. The burp valve cannula is rinsed before implantation to ensure that the burp valve is free and works properly. The duodenum is positioned and the cannulation site is isolated (i.e., 5-8cm from the duodenal bend head end). At this site, a 4-0 Prolene purse-string suture is placed on the mucosal surface, and an 18g needle is used to perforate the intestine in the center of the purse-string suture. The needle is then removed and replaced with a 16g stub adapter to further expand the existing insertion site. The stub adapter is then removed, and the burp valve tip is placed in the intestinal defect until the Dacron disk is flush with the mucosal surface. The tip is anchored by closing the purse-string suture and fixing it in place. The 4-0 Prolene suture interrupted with 7-8 is used to anchor the disk in place to the mucosal surface. A small loop was formed and the catheter body (approximately 5-6 cm from the disc) was anchored to the mucosa using the Weitzel tunneling technique.
[0423] Note: The Weitzel tunnel technique is accomplished by placing the catheter body along the intestine with its distal surface toward the duodenal curvature. 4-6 individual 5-0 Prolene sutures are placed approximately 0.5 cm apart to form a "tunnel". The tunnel is formed by attaching each suture to the mucosal surface next to the cannula and then attaching the free end to the mucosal surface on the other side of the cannula, ensuring that the sutures rest on top of the cannula. As the individual sutures are tied, they pull the mucosa over the cannula, forming a "tunnel".
[0424] After completing the Weitzel tunnel technique, a small (2-3mm) incision is made at the peritoneum about 1cm below the rib on the right side of the animal, and the catheter is externalized to the opening site by using a trocar. An incision is made on the dorsal side of the right chest, and a pocket is formed to accommodate the opening. The cannula is then moved to the pocket and attached to the opening by the trocar. The opening is then anchored to the underlying muscle tissue with a non-absorbable monofilament suture of appropriate size, and the muscle, fascia and skin are closed in an appropriate manner. The opening is rinsed with saline. The abdomen is closed in an intermittent manner with appropriate absorbable monofilament sutures. The fascia is closed in an appropriate manner respectively with appropriate absorbable sutures. The skin is closed in an appropriate manner with appropriate sutures or U-shaped staples. During anesthesia recovery, the monitoring animal recovers normal physiological function.
[0425] The incision sites were checked daily for a minimum of 14 days. Antibiotics were administered as needed. Animals were unclasped for a minimum of 14 days after the procedure.
[0426] System maintenance
[0427] Use aseptic technique to access the opening. Clip the fur above the opening as needed. Apply at least 3 alternating scrubs of chlorhexidine scrub and solution before accessing the opening via a Huber pointed needle. After dosing, flush the duodenal opening with an appropriate flushing solution such as normal saline or sterile water.

[0431] Bioanalytical methods
[0432] The bioanalytical method used to quantify the parent Mn(II) macrocyclic ring ligand structure in plasma utilized HPLC with MS / MS detection and monitored the presence of the monocationic [monoformate Mn(pentazamacrocycle)]+ complex. All bioanalytical sample measurements were performed at ABC Laboratories using the Galera bioanalytical method validated at ABC as ABC Method No. 81201-MI-02, which is similar to the method described in U.S. Pat. No. 8,444,856 to Slomczynska et al., which is hereby incorporated by reference in its entirety.
[0433] synthesis
[0434] Unless otherwise noted, all reagents used to synthesize compounds disclosed herein were purchased from Sigma-Aldrich and used without further purification.All elemental analyses were performed and reported by Galbraith Laboratories, Inc., Knoxville, TN.
[0435] The parent Mn(II) pentaazamacrocyclic dichloro complexes such as GC4419, GC4401, GC4444 and GC4403 (structures shown below) were synthesized using literature procedures. For GC4403, chiral R,R-diaminocyclohexane was used as the starting material. 2 For GC4419, the mirror image enantiomer of GC4403, chiral S,S-diaminocyclohexane was used instead. 3,4 The remainder of the synthesis of GC4419 can be identical in all respects to the published method for GC4403. 2 The synthesis of the GC4401 complex was previously reported in reference 5.
[0436]
[0437] The synthesis of GC4444 containing an additional 11-R-methyl substituent creating a fifth chiral center on carbon (and also derived from R,R-diaminocyclohexane) proceeded from the corresponding chiral tetraamine, the synthesis of which is published in reference 6 as Example 5C.
[0438] Synthesis of axial ligand derivatives
[0439] The same parent Mn(II) pentaazamacrocyclic dichloro complexes (GC4419, GC4403, GC4444 and GC4401) were also used as starting precursors for the synthesis of other axial ligand-bound derivatives using a general synthetic scheme in which a large excess of anionic salt was used to displace the chloride ligand to produce new compounds.

[0443] Using a 500-mL Erlenmeyer flask, 100 mL of deionized ("DI") water was added to 5.3 g of GC4419; the mixture was stirred vigorously for 15-20 minutes and then sonicated for 5 minutes. The resulting light brown suspension was filtered through a 10-20μ fritted funnel (about 0.3 g of solid material remained in the funnel). The resulting clear solution was added as a stream to a sodium acetate solution (approximately 429 mmol, 21 equivalents, in 100 mL of DI water) in one go. No solids separated and the light yellow solution was stirred for an additional 5 minutes. The solution was transferred to a separatory funnel and extracted with dichloromethane (3X 50 mL). The organic layers were separated, combined, and transferred back to the separatory funnel. The dichloromethane solution was back extracted (2X 50 mL) with sodium acetate aqueous solution (32 g / 100 mL). The dichloromethane layer was filtered through MgSO 4 The 1,2-dihydro-1,4-dihydro-2-nitropropene (2,4-dihydro-1,4-dihydro- ...

[0452]
[0453] Sodium pivalate (6.4 g) was added to a 125 mL conical flask and dissolved in 50 mL anhydrous EtOH (warmed to about 40 ° C) (the solution was almost colorless). Once the sodium pivalate solution was cooled back to room temperature, a solution containing 5.3 g GC4419 dissolved in 30 mL anhydrous EtOH was added (the solution was brown). Precipitation of NaCl was observed immediately after mixing. The light brown suspension was stirred for 1 h at room temperature and under Ar, and then placed in a refrigerator (2-8 ° C) overnight. The resulting light brown suspension was filtered using a tared 10-20 μ porous funnel (about 1.1 g solid sodium chloride salt remained in the funnel), and the solvent was removed from the filtrate using a rotary evaporator. The wet residue from the rotary evaporator was further vacuum dried for 15 minutes. IPA (100 mL) was added and the mixture was vortexed for 1 hour and then placed in a refrigerator overnight. The next day, after filtration, 1.28 g of white solid was separated and discarded. The clear tan-yellow filtrate was reduced to a wet solid using a rotary evaporator.
[0454] Dichloromethane (100 mL) was added to the wet solid. The mixture became a gelatinous suspension and was stirred and mixed at 37°C for 1 hour. The suspension was filtered using a tared 10-20μ porous funnel, and 1.7 g of additional white solid was separated and discarded. The solvent of the filtrate was removed using a rotary evaporator to obtain a tan slurry. MeOH (75 mL) was added to the tan slurry and a tan semi-solid was obtained after removing the solvent via a rotary evaporator. The material was vacuum dried for 72 h to obtain GC4709 as a tan solid, which was submitted for elemental analysis. HPLC showed a purity of 99.5%.

[0457]
[0458] Sodium cyclohexanebutyrate (5.77g) was added to a 125mL conical flask and then tried to dissolve it in 50mL anhydrous EtOH under stirring within 15 minutes. The mixture became gelatinous and 50mL EtOH (anhydrous) was added again, 100mL in total. This additional solvent could not obtain a clear solution after heating / ultrasound treatment (about 40°C). MeOH (10mL) was added and a clear solution was obtained after stirring / ultrasound treatment for 15 minutes. This solution was added once to a solution containing 3.6g of GC4419 dissolved in 15mL anhydrous EtOH (the color of the solution was brown). A fine suspension was obtained immediately. The suspension was stirred for 15 minutes and then placed in a freezer for 1h. A 10-15μ porous funnel was used to filter the suspension, and the clear brown filtrate was evaporated to dryness on a rotary evaporator. The resulting solid was vacuum dried overnight at room temperature. Next morning, the tan solid was stirred in 100mL dichloromethane (" DCM ") to dissolve the desired product, leaving excess cyclohexanebutyric acid sodium salt. The slurries were stirred for 3h before filtering (using 10-15 μ porous funnel and washing in funnel with 2x 30mL DCM). The yellow filtrate of gained was evaporated using a rotary evaporator, and 100mL MeOH was then added. The yellow solution of gained was evaporated again using a rotary evaporator, and the residue was placed in vacuum at room temperature overnight. The next day, the tan solid was isolated. The material was further decomposed and vacuum dried overnight, then ground using an agate mortar / pestle.
[0459] The isolated tan solid (5.4 g, 96% yield based on GC4419) was analyzed by HPLC and showed 99.6% purity.

[0462]
[0463] Sodium dodecanoate (6.17g) is added to 300mL anhydrous EtOH in a 500mL conical flask. The obtained white suspension is stirred (300rpm) while heating (about 50°C) on a hot plate. After 15 minutes, the suspension actually thickens. 100mL anhydrous EtOH is added and the obtained slurry is ultrasonically treated for 10 minutes. Then 15mL DI water (making it about 96% EtOH) is added under stirring, and the mixture is turned into a clear solution in one minute. 3.6g GC4419 dissolved in 30mL anhydrous EtOH is added to the solution. The color of the obtained solution is turbid and light brown, and it is stirred for 2h and then placed on a rotary evaporator. About half of the solvent is removed, and as the volume decreases, solid material emerges from the solution. At this time, both solid and solvent are transferred to a 25-50μ filter funnel together with the EtOH (50mL) rinse of the flask, and filtered. The light brown filtrate is then put into the rotary evaporator again. After further evaporation, a light brown solid is obtained, which is placed in vacuum overnight at room temperature. The next day, about 4.7g of a tan solid is isolated. DCM (100mL) is added and the suspension is stirred for 1h, then filtered to obtain a light yellow filtrate. After using the rotary evaporator to remove DCM, a light brown foam is obtained, which is dried in vacuo at room temperature for 48h.
[0464] The tan brittle solid (2.9 g, 44% yield) was analyzed by HPLC and showed 96.8% purity.

[0471]
[0472] Phenylglyoxylic acid (12.4 g) was added to 200 mL DI water in a 500 mL conical flask. After stirring for 5 minutes, a clear colorless solution was obtained. This was treated with 3.2 g NaOH in pellet form, and the mixture was stirred vigorously. The pH was measured when all the NaOH was dissolved. The pH was 3.61, and the pH was adjusted to about 8.5-9 using a 5 wt % NaOH aqueous solution.
[0473] A turbid solution of 5 g of GC4419 in 75 mL of DI water was filtered through a 10-20 μ filter funnel and added to about half of the pH-adjusted aqueous sodium phenylglyoxylate solution (about 110 mL) at one time. The precipitated white material was stirred for another 15 minutes, and then 100 mL of DCM was added. A yellow DCM layer was immediately produced.

[0573] The examples cited above show that axial ligands bonded to Mn(II) ions can exert very profound and previously unpredicted effects on the ability of these complexes to penetrate the GI tract and become orally bioavailable. We have discovered that there is a fairly narrow subset of ligand structures that can greatly enhance gastrointestinal (GI) uptake and thereby greatly improve oral bioavailability. This subset of axial ligand structures that provide enhanced oral bioavailability includes Fig.10 Those shown in .
[0574] There are some significant structural features that influence bioavailability. First, a broad range of alkyl carboxylic acid structures were screened for oral bioavailability in various oils, and it was observed that they were not equivalent in providing high oral bioavailability. In fact, the propionate ligand (and the related lactate ligand - a propionate ligand with an OH replacing the H, and possibly other ligands based on the propionate ligand) provide much better bioavailability than any other carboxylate ligand; such as the one carbon atom shorter chain, acetate, or longer chain carboxylate ligands such as butyrate or octanoate. Second, there is a unique class of axial ligands derived from phenylacetic acid; namely, the phenylacetate ligand. These derivatives are Fig.10As shown. Compared with the parent dichloro complex or with other alkyl carboxylate ion complexes (complexes derived from acetate ions or other higher molecular weight carboxylate ion ligands), all complexes derived from the phenylacetate ion class ligands have greatly improved bioavailability. Third, one of these derivatives is based on an amino acid, phenylglycine. The racemic-phenylglycine root ion ligand enhances the bioavailability of all tested various pentaaza macrocyclic ligands, indicating that this is not only an isolated effect of the parent manganese pentaaza macrocyclic compound of GC4419, but also general to this Mn (II) complex family. In addition, the L-phenylglycine root ion derivative GC4702 of GC4419 is actually more easily absorbed than other amino acid ligands (such as L-phenylalanine root ion or L-valine root ion complexes) or the rac-phenylglycine root ion complex GC4720. Furthermore, this bioavailability enhancing property may be limited to phenylglycinate ligand derivatives (also derivatives of phenylacetic acid), as exemplified by the extremely poor bioavailability of complexes derived from L-phenylalanine homologues or L-valine homologues, although other amino acid ligands, particularly L-alanine homologues belonging to the above-mentioned propionate ion-based ligand class, may also provide good bioavailability.
