  Design and Synthesis of New 2-Aryl-4,5-Dihydro-thiazole Analogues: In Vitro Antibacterial Activities and Preliminary Mechanism of Action

  摘要：

  通过一种新型的无金属和催化剂方法，设计并合成了 60 个 2-芳基-4,5-二氢噻唑类化合物，其中半胱氨酸和取代苯腈类化合物的产率为 64% 至 89%。标题化合物的结构主要通过核磁共振光谱数据分析得到了证实。抗菌活性测定结果表明，(S)-2-(2′-羟基苯基)-4-羟甲基-4,5-二氢噻唑（7h）和(R)-2-(2′-羟基苯基)-4-羟甲基-4,5-二氢噻唑（7h′）化合物对茄属拉氏菌（Ralstonia solanacearum）、丁香假单胞菌（Pseudomonas syringae pv.最低抑菌浓度为 3.91 μg-mL-1 至 31.24 μg-mL-1。取代基的影响表明，不仅取电子基团会削弱抗菌活性，而且供电子基团也会削弱抗菌活性，除非在 4,5-二氢噻唑类似物的 2-芳基取代基上引入 2′-羟基。扫描电子显微镜（SEM）和脂肪酸暴露实验的结果表明，这些抗菌化合物会影响受试细菌的脂肪酸合成。

  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−activity relationship 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

  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 rationally designed and synthesized. The in vitro bioassay results indicated that compound 7c showed broad-spectrum

  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.

  Sixty 2-aryl-4,5-dihydrothiazoles were designed and synthesized in yields ranging from 64% to 89% from cysteine and substituted-benzonitriles via a novel metal- and catalyst-free method. The structures of the title compounds were confirmed mainly by NMR spectral data analysis. Antibacterial activity assays showed that the compounds (S)-2-(2′-hydroxyphenyl)-4-hydroxy-methyl- 4,5-dihydrothiazole (7h) and (R)-2-(2′-hydroxyphenyl)-4-hydroxymethyl-4,5-dihydro-thiazole (7h′) exhibited significant inhibition against Ralstonia solanacearum, Pseudomonas syringae pv. actinidiae, Bacillus subtilis and Bacillus cereus, with minimum inhibitory concentrations (MICs) ranging from 3.91 to 31.24 μg·mL−1. The effect of substituents showed that not only electron-withdrawing groups, but also electron-donating groups could abolish the antibacterial activities unless a 2′-hydroxy group was introduced on the 2-aryl substituent of the 4,5-dihydrothiazole analogues. The results of scanning electron microscope (SEM) and fatty acid exposure experiments indicated that these antibacterial compounds influence fatty acid synthesis in the tested bacteria.
