Structure–Activity relationships within a series of caspase inhibitors: effect of leaving group modifications
摘要:
Various aryloxy methyl ketones of the 1-naphthyloxyacetyl-Val-Asp backbone have been prepared. A systematic study of their structure-activity relationship (SAR) related to caspases 1, 3, 6, and 8 is reported. Highly potent irreversible broad-spectrum caspase inhibitors have been identified. Their efficacy in cellular models of cell death and inflammation are also discussed. (C) 2003 Elsevier Ltd. All rights reserved.

The invention relates to substituted polycyclic aryl and heteroaryl tertiary-heteroalkylamine compounds useful as inhibitors of cholesteryl ester transfer protein (CETP; plasma lipid transfer protein-I) and compounds, compositions and methods for treating atherosclerosis and other coronary artery diseases. Preferred tertiary-heteroalkylamine compounds are substituted N,N-disubstituted diamines. A preferred specific N,N-disubstituted diamine is the compound:

A simple and sustainable one-step strategy for the preparation of electron-deficient aryl trifluoromethyl ethers (ArOCF3) from the corresponding phenols by electrochemical synthesis is presented. Anodic oxidation of trifluoromethane sulfinate (Langlois reagent) leads to direct O-trifluoromethylation of phenol-derivatives bearing fluorine, chlorine, bromine and nitrile substituents under mild conditions
