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.

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.

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
The condensation of L-cysteine and aryl nitriles to (R)-2-aryl-4,5-dihydrothiazole-4-carboxylic acids in buffered media was reinvestigated. Pure products (yields of 58-95%; up to 99% ee) were obtained in a NaHCO3/NaOH-buffered aqueous alcoholic medium.
