lipophilic chalcones, in particular those with 4'-hydroxyl-substituted B rings and hetero/polyaromatic A rings. In contrast, chalcones with good antimalarial activity have alkoxylated B rings and electron-deficient A rings. Visualization of the steric and electrostatic fields generated from comparative molecular field analysis (CoMFA) indicate that the ring A of chalcones make a more significant contribution
2'-Hydroxy chalcone derivatives having heteroaromatic rings have been synthesized and their photochemical and photophysical properties have been examined in terms of tautomer produced by intramolecular hydrogen atom transfer reaction.
New hybrid bromopyridine-chalcones as in vivo phase II enzyme inducers: potential chemopreventive agents
administration of cancer chemopreventive agents (CCAs) that prevent, delay or reverse the carcinogenic process. CCAs that are able to induce detoxification enzymes, especially monofunctional phase II enzymes, have become an excellent therapeutic strategy. Herein, we report the synthesis of eighteen new potential CCAs, structurally designed to combine (naphtho)chalcone and (bromo)pyridine skeletons. After a selection
