Discovery of a novel EP2/EP4 dual agonist with high subtype-selectivity
摘要:
A series of gamma-lactam prostaglandin E(1) analogs bearing a 16-phenyl moiety in the omega-chain and aryl moiety in the alpha-chain were synthesized and biologically evaluated. Among the tested compounds, gamma-lactam PGE analog 3 designed as a structural hybrid of 1 and 2 was discovered as the most optimized EP2/EP4 dual agonist with excellent subtype-selectivity (K(i) values: mEP2 = 9.3 nM, mEP4 = 0.41 nM). A structure-activity relationship study is presented. (C) 2011 Elsevier Ltd. All rights reserved.

The present disclosure describes novel compounds of the general Formula (I), their analogs, tautomeric forms, stereoisomers, polymorphs, hydrates, solvates, pharmaceutically acceptable salts, pharmaceutical compositions, metabolites, and prodrugs thereof. These compounds can inhibit both LSD and HDAC and are useful as therpeautic or ameliorating agent for diseases that are involved in cellular growth such as malignant tumors, schizophrenia, Alzheimer's disease, parkinson's disease and the like.
To identify potent EP2/EP4 dual agonists with excellent subtype selectivity, a series of c-lactam prostaglandin E analogs bearing a 16-phenyl x-chain were synthesized and evaluated. Structural hybridization of 1 and 2, followed by more detailed chemical modification of the benzoic acid moiety, led us to the discovery of a 2-mercaptothiazole-4-carboxylic acid analog 3 as the optimal compound in the series. An isomer of this compound, the 2-mercaptothiazole-5-carboxylic acid analog 13, showed 34-fold and 13-fold less potent EP2 and EP4 receptor affinities, respectively. Structure activity relationship data from an in vitro mouse receptor binding assay are presented. Continued evaluation in an in vivo rat model of another 2-mercaptothiazole-4-carboxylic acid analog 17, optimized for sustained compound release from PLGA microspheres, demonstrated its effectiveness in a rat bone fracture-healing model following topical administration.
