Optimization of Hydroxybenzothiazoles as Novel Potent and Selective Inhibitors of 17β-HSD1
摘要:
17 beta-HSD1 is a novel target for the treatment of estrogen-dependent diseases, as it catalyzes intracellular estradiol formation. Starting from two recently described compounds, highly active and selective inhibitors were developed. Benzoyl 6 and benzamide 17 are the most selective compounds toward 17 beta-HSD2 described so far. They also showed a promising profile regarding activity in T47-D cells, selectivity toward ER alpha and ER beta inhibition of hepatic CYP enzymes, metabolic stability, and inhibition of marmoset 17 beta-HSD1 and 17 beta-HSD2.

with heteroaromatic trifluoromethyl ketone hydrates in neat water has been developed for the synthesis of α-trifluoromethyl tertiary alcohols bearing N-heteroaromatics. This method not only features excellent efficiency, broad substrate scope, catalyst-free conditions, and easy gram-scale preparation but also represents a new and rare example of “all-water” synthesis of trifluoromethylated molecules.

An efficient organocatalytic enantioselective cross-aldol reaction of aryl ketones with heteroaromatic trifluoromethyl ketone hydrates via enolate intermediates has been developed. The cross-aldol reactions catalyzed by Takemoto-type thiourea catalysts proceeded well under mild conditions, furnishing a variety of enantioenriched α-trifluoromethyl tertiaryalcohols bearing N-heteroaromatics with good
