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

hospital-acquired, Gram-negative pathogens, poses a significant threat to public health. We report several 2-substituted 4,5-dihydrothiazole-4-carboxylic acids to be novel MBL inhibitors. Structure activity relationship (SAR) and molecular modeling studies were performed and implications for further inhibitor design are discussed.
natural product 2‐aryl‐4,5‐dihydrothiazole‐4‐carboxylic acid, a series of novel (R)‐2‐aryl‐4,5‐dihydrothiazole‐4‐carboxylic acidderivatives were designed and synthesized. Their structures were characterized by 1H NMR, 13C NMR and HRMS. The single crystal structure of compound 9b was determined by X‐ray diffraction analysis. The antifungalactivities were evaluated for the first time. The bioassay results

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
