Four different classes of new 17 beta-hydroxysteroid dehydrogenase type 2 (17 beta-HSD2) inhibitors were synthesized, in order to lower the cytotoxicity exhibited by the lead compound A, via disrupting the linearity and the aromaticity of the biphenyl moiety. Compounds 3, 4, 7a and 8 displayed comparable or better inhibitory activity and selectivity, as well as a lower cytotoxic effect, compared to the reference compound A. The best compound 4 (IC50 = 160 nM, selectivity factor = 168, LD50 approximate to 25 mu M) turned out as new lead compound for inhibition of 17 beta-HSD2. (C) 2015 Elsevier Ltd. All rights reserved.
Synthesis and antiproliferative activity of novel 4-substituted-phenoxy-benzamide derivatives
A series of novel 4-substituted-phenoxy-benzamide derivatives bearing an aryl cycloaliphatic amine moiety were synthesized and evaluated for antiproliferative activity against SW620, HT29 and MGC803 cancer cell lines in vitro. The pharmacological data demonstrated that the majority of target compounds exhibited moderate efficacy in HT29 and MGC803 cell lines. Compound 10c showed promising inhibition of hedgehog (Hh) signaling pathway in an Hh-related assay. In addition, the superposition pattern of 10c showed a good fit for a pharmacophoric model generated by Hh inhibitors and provided a basis for further structural optimization.

Synthesis and structure-activity relationships (SAR) of arginine vasopressin (AVP) receptor modulators are described. Potent and selective compounds are prepared when the amide linkage connecting rings A and B of VPA-985 is replaced with a bond, C=O, -O-, -S-, or -SO2- bond. (c) 2005 Elsevier Ltd.
