The disclosure provides diphenyl compounds and the use thereof as growth factor pathway activators.
Growth factors are signaling molecules which bind their cognate cell surface receptors initiating signaling cascades that stimulate a variety of cellular processes including growth, metabolism, survival, migration and differentiation. One of the key growth factor signaling pathways is the PI3K (Phosphoinositide 3 Kinase)/Akt/mTOR (Mechanistic Target of Rapamycin) pathway. Akt (also called Protein Kinase B, PKB) is a serine/threonine kinase that mediates growth factor signaling by phosphorylating multiple cellular targets. (Manning B D, Cantley L C. AKT/PKB signaling: navigating downstream. Cell. 2007 Jun. 29; 129(7):1261-74.)
Impaired growth factor signaling can lead to various disease conditions including skeletal muscle loss, hearing loss, degeneration of a number of organ systems and delayed wound healing. (Rüegg M A, Glass D J. Molecular mechanisms and treatment options for muscle wasting diseases. Annu Rev Pharmacol Toxicol. 2011; 51:373-95; Yamamoto N, Nakagawa T, Ito J. Application of insulin-like growth factor-1 in the treatment of inner ear disorders. Front Pharmacol. 2014 Sep. 10; 5:208; Böhm F, Kohler U A, Speicher T, Werner S. Regulation of liver regeneration by growth factors and cytokines. EMBO Mol Med. 2010 August; 2(8):294-305; Sádaba M C, Martin-Estal I, Puche J E, Castilla-Cortázar I.

Insulin-like growth factors and kidney disease. Am J Kidney Dis. 2015 February; 65(2):327-36; Mitchell A C, Briquez P S, Hubbell J A, Cochran J R. Engineering growth factors for regenerative medicine applications. Acta Biomater. 2016 January; 30:1-12.) With the dramatic rise in the prevalence of diabetes, age and diabetes-associated non-healing chronic wounds are a critical health problem in the world today. (Demidova-Rice T N, Hamblin M R, Herman I M. Acute and impaired wound healing: pathophysiology and current methods for drug delivery, part 1: normal and chronic wounds: biology, causes, and approaches to care. Adv Skin Wound Care. 2012 July; 25(7):304-14.) Injury typically induces expression of growth factor receptors, and growth factors are involved in all stages of the wound healing process: coagulation, inflammation, formation of granulation tissue and remodeling or scar formation. (Demidova-Rice T N, Hamblin M R, Herman I M. Acute and impaired wound healing: pathophysiology and current methods for drug delivery, part 2: role of growth factors in normal and pathological wound healing: therapeutic potential and methods of delivery. Adv Skin Wound Care. 2012 August; 25(8):349-70; Goldman R. Growth factors and chronic wound healing: past, present, and future. Adv Skin Wound Care. 2004 January-February; 17(1):24-35.) Chronic wounds (vascular ulcers, diabetic ulcers and pressure ulcers) are characterized by decreased density of growth factor receptors and reduced mitogenic response to growth factors. (Demidova-Rice T N et al., supra, Adv Skin Wound Care. 2012 August; 25(8):349-70; Goldman R., supra, Adv Skin Wound Care. 2004 January-February; 17(1):24-35.)
The current paradigm for treating chronic wounds involves debridement (surgical or with debridement agents), control of infection and inflammation (with antibiotics and anti-inflammatory agents), correction of moisture imbalance (with wound dressings) and promotion of re-epithelialization/granulation tissue formation (with growth factors). (Demidova-Rice T N et al., supra, Adv Skin Wound Care. 2012 July; 25(7):304-14.) IGF-1/Insulin are well validated in wound healing both in preclinical and clinical settings, and mouse models of activated PI3K/Akt/mTOR signaling axis show accelerated wound closure. (Mori R, Tanaka K, de Kerckhove M, Okamoto M, Kashiyama K, Tanaka K, Kim S, Kawata T, Komatsu T, Park S, Ikematsu K, Hirano A, Martin P, Shimokawa I. Reduced FOXO1 expression accelerates skin wound healing and attenuates scarring.

The only FDA approved treatment for chronic wounds is Becaplermin (Regranex) which contains recombinant PDGF and has had limited efficacy. (Eaglstein W H, Kirsner R S, Robson M C. Food and Drug Administration (FDA) drug approval end points for chronic cutaneous ulcer studies. Wound Repair Regen. 2012 November-December; 20(6):793-6.) Recombinant PDGF has several drawbacks as a treatment for chronic wounds, including its short half-life in the protease-rich hostile wound microenvironment and insufficient delivery mechanisms. A need remains for growth factor pathway activators that bypass growth factor receptors (which are downregulated in chronic wounds), have increased stability, and pose no risk for immunogenicity.

In the formulas, a line traversing a ring and bonded to a substituent group (e.g., an R group) means that the substituent may be bound in place of hydrogen to any ring atom where the valency of the atom allows. For example, the R group in formula (I) may be bound to any carbon atom of the phenyl ring traversed by the line, except for the carbon atom bound to the rest of the molecule through the methylene group and the carbon atom bound to the R4 substituent. Where the line traverses a ring in a bicyclic ring system (fused, bridged, or spiro), the substituent group may be bound to any ring atom in any ring of the system.

In step (ii), 4-bromophenyl hydrazine (2) is converted to pyrazole or triazole 3. Conversion to the pyrazole (X=CH) can be accomplished by treating hydrazine 2 with a suitable ethyl 2,4-dioxoalkanoate (EtOC(O)C(O)CH2C(O)R1).

In step (iv), compound 9 is converted to pyrazole or triazole 10 (both of which are themselves compounds of formula (I)). Conversion to the pyrazole (X=CH) can be accomplished by converting compound 9 to the corresponding hydrazine (e.g., by treatment with sodium nitrite and aqueous acid), treating the hydrazine with a suitable ethyl 2,4-dioxoalkanoate (EtOC(O)C(O)CH2C(O)R1) to afford a pyrazole carboxylate ethyl ester intermediate, and converting the ester to the amide 10. The ester may be converted directly to the amide (e.g., by treatment with ammonia gas in dry methanol), or conversion may be accomplished by hydrolysis of the ester (e.g., by treatment with LiOH in methanol), followed by amide formation (e.g., by treatment with ammonia in the presence of HATU and a base). Conversion to the triazole (X=N) can be accomplished by converting compound 9 to the corresponding hydrazine (e.g., by treatment with sodium nitrite and aqueous acid), treating the hydrazine with a suitably substituted diethyl amidomalonate (EtOC(O)CH(NHC(O)R1)C(O)OEt) to afford a triazole carboxylate ethyl ester intermediate, and converting the ester to the amide 10.

Alternatively, in step (i-a), Miyaura borylation of compound 5 or 10 affords boronate ester intermediate 12 (step (i-a)), followed by Suzuki coupling of intermediate 12 with an aryl, heteroaryl, or vinyl halide or triflate of formula A-L (where L is Cl, Br, I, or OTf) affords compound 11.
In step (ii), further modification of the A substituent in compound 11 according to well-known methods, such as cross-coupling (e.g., Suzuki coupling, Sonogashira coupling), amide coupling, reductive amination, hydrogenation, and the like, to arrive at the desired R4 substituent affords the compound of formula (I). For some R4 substituents, it is possible to couple the R4 substituent directly to compound 5 or 10 in step (i), such that step (ii) is unnecessary. In such cases, A is R4, and compound 11 is the compound of formula (I).

The solution was concentrated in vacuo and dried under vacuum overnight to afford the product (4 mg, 2%): LCMS Rt=1.41 min (condition A), MS (M+1)=468.4. 1H NMR (400 MHz, Methanol-d4) δ 7.55-7.48 (m, 6H), 7.48-7.42 (m, 2H), 7.33-7.26 (m, 2H), 6.98-6.91 (m, 2H), 5.00-4.91 (m, 1H), 4.10 (s, 2H), 2.96-2.83 (m, 3H), 2.55-2.47 (m, 4H), 2.43-2.33 (m, 4H), 2.07-1.94 (m, 1H).
1-(4-Chlorophenyl)-1-methyethylamine (0.4 g, 2.358 mmol) was added to THF (10 mL) followed by base K2CO3 (0.815 g, 5.89 mmol). The mixture was cooled to 0° C. and benzyl 2-bromoacetate (0.448 mL, 2.83 mmol) was added slowly. The reaction was allowed to warm to room temperature and stirred overnight. The resultant slurry was then added to brine and the organic materials extracted into ethyl acetate. The organic layers were dried with magnesium sulfate and reduced under pressure. The resulting crude product was purified by FCC (gradient 2%-10% MeOH in DCM) to afford benzyl (2-(4-chlorophenyl)propan-2-yl)glycinate (0.6 g, 80%): LCMS Rt=0.78 min (condition B), MS (M+1)=318.1.
A solution of benzyl (2-(4-chlorophenyl)propan-2-yl)glycinate (0.3 g, 0.944 mmol) in tetrahydrofuran (6 mL) was cooled to −15° C., and treated with zirconium(IV) chloride (0.264 g, 1.133 mmoL). The mixture was stirred at −15° C. for 30 minutes and a 3M solution of methylmagnesium bromide in ether 1.888 mL, 5.66 mmol) was slowly added. The reaction mixture was warmed to RT slowly and stirred overnight. 25% sodium hydroxide aqueous solution was added to quench the reaction. The mixture was extracted with dichloromethane, and the organic layer was washed with water and brine, and concentrated in vacuo. The resulting crude product was purified by FCC (gradient 10-60% hexane in ethyl acetate) to afford 2-(benzyloxy)-N-(2-(4-chlorophenyl)propan-2-yl)-2-methylpropan-1-amine (0.09 g, 28%): LCMS Rt=0.81 min (condition B), MS (M+1)=332.2.
A microwave vial was charged with methyl-1-(4-(2-(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)propan-2-yl)phenyl)-1H-pyrazole-3-carboxamide (Intermediate IX) (100 mg, 0.239 mmol), 2-(benzyloxy)-N-(2-(4-chlorophenyl)propan-2-yl)-2-methylpropan-1-amine (87 mg, 0.263 mmol), K3PO4 (152 mg, 0.717 mmol), second generation Xphos Precatalyst (18.81 mg, 0.024 mmol), water (0.5 mL), THF (2 mL), and was evacuated and degassed with N2 for 5 min. The mixture was heated in the microwave at 100° C. for 2 hr, cooled to RT, and concentrated in vacuo. The resulting crude product was purified by FCC (gradient 2%-10% MeOH in DCM) then by preparative HPLC to afford 1-(4-((4′-(2-((2-hydroxy-2-methylpropyl)amino)propan-2-yl)-[1,1′-biphenyl]-4-yl)methyl)phenyl)-5-methyl-1H-1,2,4-triazole-3-carboxamide (4 mg, 3%): LCMS Rt=1.44 min (condition A), MS (M+1)=498.4. 1H NMR (400 MHz, Methanol-d4) δ 7.60-7.49 (m, 8H), 7.46 (d, J=8.5 Hz, 2H), 7.32 (d, J=8.1 Hz, 2H), 4.11 (s, 2H), 2.52 (s, 3H), 2.28 (s, 2H), 1.49 (s, 6H), 1.16 (s, 6H).
Phosphorylation of Akt on S473 and FoxO3a nuclear to cytoplasmic translocation were used as readouts of PI3K/Akt/mTOR pathway activation downstream of growth factor signaling.
Reporter cell line. U2OS GFP-FoxO3a H212R reporter cell line was established by transducing U2OS cells with the retroviral plasmid pLEGFP-C1 containing FoxO3a H212R transgene and selecting for G418 resistant clones.
Reporter assay. U2OS GFP-FoxO3a H212R cells were plated in 384-well plates at 4000 cells per well in 30 microliters of McCoy's 5A medium containing 10% FBS. On day 1 the cells were washed with serum free medium and serum starved overnight. On day 2 the cells were treated with different doses of the compounds for 30 minutes, fixed with 4% Paraformaldehyde for 1 hour and stained with Phospho-AKT (Ser473) antibody (Cell Signaling Technology, catalog #4060) overnight at 4° C. After nuclei staining with Hoechst 33342 (Life Technologies, catalog # H3570) the plates were imaged with InCell 2000 (GE Healthcare Bio-Sciences). FoxO3a inhibition activity is calculated as the ratio of nuclear to cytosolic GFP intensity in percent. Akt activation is measured as the total cellular intensity of Phospho-Akt antibody staining in percent. DMSO control is set as 0% activity.
Results. The measured FoxO3a inhibition activity and Akt activation activity are reported in the following table:
