摘要:
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.
