3-(2-Aminocarbonylphenyl)propanoic acid analogs as potent and selective EP3 receptor antagonists. Part 1: Discovery and exploration of the carboxyamide side chain
摘要:
A series of 3-(2-aminocarbonyl-4-phenoxymethylphenyl) propanoic acid analogs were synthesized and evaluated for their EP3 antagonist activity in the presence of additive serum albumin. Several compounds were biologically evaluated for their in vivo efficacy with respect to the PGE(2)-induced uterine contraction in pregnant rats as well as their pharmacokinetics. The discovery process of these potent and selective EP3 antagonists and their structure activity relationship are also presented. (C) 2009 Elsevier Ltd. All rights reserved.

Abstract Grignardreagents add to benzonitrile at low temperature catalyzed by CuBr and TBSCl affording N-TBS ketimines, which were investigated as intermediaries for the synthesis of primary amines and ketones. N-silylimines were easily obtained by an organolithium addition to benzonitrile followed by a reaction with TBSCl in CH2Cl2. In situ reduction of these imines by BH3 and 1,3,2-oxazaborolidines

A convenient Fe-catalyzed decarbonylative alkylation–azidation cascade reaction of styrene derivatives with aliphatic aldehydes and TMSN3 to provide aliphatic azides is developed. With DTBP as an oxidant and radical initiator, this reaction smoothly converts aliphatic aldehydes into 1°, 2° and 3° alkyl radicals and subsequently allows for the cascade construction of C(sp3)–C(sp3) and C(sp3)–N bonds
An epoxysuccinic acid derivative having the following formula: ##STR1## \x9bwherein R.sup.1 is hydrogen, alkyl, aryl, or aralkyl; each of R.sup.2 and R.sup.3 independently is aryl, aralkyl or alkyl; X is --O-- or --NR.sup.4 --; and R.sup.4 is hydrogen, alkyl, or aralkyl! is useful for prevention and treatment of bone diseases such as osteoporosis, malignant hypercalcemia and Paget's syndrome, and further useful for treatment of osteoarthritis and rheumatoid arthritis which are accompanied by abnormal enhancement of cathepsin L activity, and furthermore useful as a medicine for treating diseases in which cathepsin B and L participate, such as muscular dystrophy and muscular atrophy.
