A novel series of urea-based peptidomimetic calpain inhibitors
摘要:
A series of peptide aldehyde derivatives in which the P-2 chiral carbon has been replaced with nitrogen were synthesized as urea-based peptidomimetic inhibitors of mu-calpain. The compounds mirrored the general SAR of peptidyl aldehyde calpain inhibitors but displayed greater selectivity for mu-calpain over cathepsin B. (C) 2006 Elsevier Ltd. All rights reserved.

日期:——
CuH-catalyzed Z-selective partial reduction of alkynyl amides to afford α,β-unsaturated amides using silane as the hydrogen donor is developed. This reaction is carried out under mild conditions and able to accommodate a broad scope of alkynyl amides including those bearing a terminal carbon–carbon double bond or triple bond, affording alkenyl amides with high stereoselectivity and excellent yields.
