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
fumonisin caused by Fusarium verticillioides pose a serious threat to food security. To find more highly active fungicidal and antitoxic candidates with structure diversity based on naturally occurring lead xanthatin, a series of novel spiropiperidinyl-α-methylene-γ-butyrolactones were rationallydesigned and synthesized. The in vitro bioassay results indicated that compound 7c showed broad-spectrum

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
