Reaction of O-Alkyl-N-substituted Iminothiocarbonates with Bromoacetyl Bromide. A General Method for the Synthesis of 3-Substituted 1,3-Thiazolidine-2,4-diones
chitinase (OfChi-h) from Ostrinia furnacalis (Asian corn borer) in this work, except for previously reported OfChtI. Novel piperonyl-tethered rhodaninederivatives 7a–j were rationally designed with piperine as lead and synthesized by introducing a unique rhodanine moiety into the piperine scaffold based on the similar binding cavity of OfChtI and OfChi-h. Compared to piperine, compounds 7a–j showed approximately
A new class of 3-aryl-rhodanine benzoic acid derivatives were designed, synthesized, and evaluated for their inhibition activities against anti-apoptotic Bcl-2 proteins. The potent compounds 33 and 41 bound to Bcl-2 with submicromolar K-i values and had selectivities to Bcl-2/Mcl-1 over Bcl-xL. In addition, they exhibited obvious antiproliferative activities in three human tumor cell lines (MDA-MB-231, K562 and PC-3). (C) 2015 Elsevier Ltd. All rights reserved.
