Synthesis of aryl dihydrothiazol acyl shikonin ester derivatives as anticancer agents through microtubule stabilization
摘要:
The high incidence of cancer and the side effects of traditional anticancer drugs motivate the search for new and more effective anticancer drugs. In this study, we synthesized 17 kinds of aryl dihydrothiazol acyl shikonin ester derivatives and evaluated their anticancer activity through MTT assay. Among them, C13 showed better antiproliferation activity with IC50 = 3.14 +/- 0.21 mu M against HeLa cells than shikonin (IC50 = 5.75 +/- 0.47 mu M). We then performed PI staining assay, cell cycle distribution, and cell apoptosis analysis for C13 and found that it can cause cell arrest in G2/M phase, which leads to cell apoptosis. This derivative can also reduce the adhesive ability of HeLa cells. Docking simulation and confocal microscopy assay results further indicated that C13 could bind well to the tubulin at paclitaxel binding site, leading to tubulin polymerization and mitotic disruption.

ylic acid amides (ATCAA). The antiproliferative activity of the SMART agents against melanoma and prostate cancer cells was improved from μM to low nM range compared with the ATCAA series. The structure−activityrelationship was discussed from modifications of “A”, “B”, and “C” rings and the linker. Preliminary mechanism of action studies indicated that these compounds exert their anticancer activity

Cu(I)-Catalyzed oxidative homo-coupling of thiazoline-4-carboxylates with good functional group tolerance has been developed. The methodology presented an efficient method to directly construct vicinal carbon-hetero quaternary centers existing in numerous functional molecules and could be applied to the synthesis of 4,4′-bithiazoles which are difficult to prepare by direct C–H activation.

A series of (R)-2-phenyl-4,5-dihydrothiazole-4-carboxamide derivatives containing a diacylhydrazine moiety were designed and synthesized. Their structures were confirmed by melting points, 1H NMR, 13C NMR, and elemental analysis (EA). Their antifungal and insecticidal activities were evaluated. The antifungal activity result indicated that most title compounds against Cercospora arachidicola, Alternaria

Abstract A series of (R)-2-phenyl-4,5-dihydrothiazole-4-carboxamide derivativescontaining a sulfur ether moiety were synthesized and characterized on the basis of NMR and elemental analysis (EA). The crystal structure of (R)-N-(2-methyl-1-(methylthio)propan-2-yl)-2-(4-nitrophenyl)-4,5-dihydrothiazole-4-carboxamide (13d) was determined to show R configuration. The bioasssy results indicated that most
