Chain-branched 1,3-dibenzylthioureas as vanilloid receptor 1 antagonists
摘要:
A series of chain-branched 1,3-dibenzylthiourea derivatives were synthesized, and tested their antagonist activity against vanilloid receptor 1. Chain-branching led to a significant change in the mode of action and the potency. (R)-Methyl or ethyl-branched 1,3-dibenzylthiourea derivatives showed the most potent antagonist activity up to the IC50 value of 0.05 muM which is 10-fold more potent than capsazepine.

COX-1/COX-2 inhibitors based on the methanone moiety
摘要:
This paper focuses on the synthesis and the in vitro testing of dual COX-1/COX-2 inhibitors. Starting from structures of non-steroidal anti-inflammatory drugs (NSAIDs) the diaryl methanone element was chosen as a lead. Modifications were carried out on this scaffold to obtain potent inhibitors of the COX enzymes. The N-(2-aroylphenyl)sulphonamides and -amides were studied in detail, and to consolidate the data evaluated the corresponding 3- and 4-regioisomers were also investigated. The potency and the enzyme selectivity were varied by structural modifications of the lead. (C) 2002 Published by Editions scientifiques et medicales Elsevier SAS.
Triphenylethylenes having an N-(dialkylaminoalkyl)alkanesulfonamide substituent in the one of the phenyl rings may be prepared from similarly substituted benzophenones by reaction thereof with a benzyl Grignard reagent followed by dehydration of the resulting triphenylethanol intermediate and if desired chlorination or nitration of the resulting product. The triphenylethylenes have estrogenic and post-coital antifertility action and are useful as intermediates for the preparation of other triphenylethylene compounds.
