Design, synthesis and in vitro evaluation of amidoximes as histone deacetylase inhibitors for cancer therapy
摘要:
Amindoximes are geometric isomers of N-hydroxyamidines which are bioisosteres of hydroxamates. Since amindoxime group is capable of chelating transition metal ions including zinc ion, amindoximes should possess histone deacetylases (HDACs) inhibitory activity. In this work, we designed and synthesized a series of amindoximes, examined their inhibitory activities against HDACs, and investigated their cytotoxicity to human cancer cells. Preliminary results demonstrated that amindoximes possessed submicromolar HDACs inhibitory activity, with noteworthy enhancement compared with hydroxamates. Furthermore, the amindoximes arrested HCT116 and A549 cells in G2/M phase and showed good efficacy in inducing cells death. We provided a proof-of-concept that amindoximes could be used as HDACs inhibitors and hold great promise as epigenetic drugs. (C) 2016 Elsevier Ltd. All rights reserved.
Catalytic enantioselective [2,3] Stevens and Sommelet-Hauser rearrangements of α-diazo pyrazoleamides with sulfides were achieved by utilizing chiral N,N'-dioxide/nickel(II ) complex catalysts. These rearrangements proceeded well under mild reaction conditions, providing rapid and facile access to a series of functionalized 1,6-dicarbonyls or sulfane-substituted phenylacetates with high to excellent
3-Indolinedione derivatives have been identified as a novel class of promising agents for cancer treatment. In this study, eighteen 2,3-indolinedione derivatives were designed and synthesized, and their anticancer activities against mantle cell lymphoma (MCL) cells were evaluated. Most of them exhibited significant antiproliferative activity against the tested cell lines, and compound K5 was the most

evaluated in mantle cell lymphoma (MCL) cell lines. We demonstrated that target compounds had made great progress in improvement of antiproliferativeactivity compared to lead compound. Compounds 13c, 13g, 13h, 13l, 13n and 13o demonstrated effectively antiproliferativeactivity in MCL cells lines with single-digit micromolar potency. Furthermore, compound 13l specifically disturbed mitochondrial membrane

fragment hopping approach is widely applied in drug development. A series of diarylpyrimidines (DAPYs) were obtained by hopping the thioacetamide scaffold to novel human immunodeficiency virus type 1 (HIV-1) nonnucleoside reversetranscriptaseinhibitors (NNRTIs) to address the cytotoxicity issue of Etravirine and Rilpivirine. Although the new compounds (11a-l) in the first-round optimization possessed less
