Discovery of trans-3-(pyridin-3-yl)acrylamide-derived sulfamides as potent nicotinamide phosphoribosyltransferase (NAMPT) inhibitors for the potential treatment of cancer
Nicotinamidephosphoribosyltransferase (NAMPT) has emerged as a promising target for the discovery of anticancer drugs. Based on NAMPTinhibitorFK866 that has been advanced into phase II trial, we identified a trans-3-(pyridin-3-yl)acrylamide compound 13 incorporating with a biarylsulfanilamide moiety as a new NAMPTinhibitor. Further structure-activity relationship (SAR) exploration led to additional

The title reagent engaged in the modified Julia olefination with aldehydes under mild reaction conditions (DBU, CH(2)Cl(2), rt or -78 degrees C) to yield alpha,beta-unsaturated esters; aryl aldehydes and aliphatic aldehydes possessing significant chain branching elements gave trans alkene products with high stereoselectivity (E : Z up to >98 : 2), while straight chain aliphatic aldehydes gave cis products
