3-triazole tagged pyrazolo[3,4-b]pyridine derivatives 3 and 4 were prepared respectively starting from 6-phenyl-4-(trifluoromethyl)-1H-pyrazolo[3,4-b]pyridin-3-amine 1 via selective N-propargylation, followed by reaction with diverse substituted alkyl/perfluoroalkyl/aryl/aryl amide azides under Sharpless conditions. All the synthesized compounds 3 and 4 were screened for cytotoxicactivity against four

highly efficient method for the synthesis of 2-imino-4-(trifluoromethyl)thiazolidin-4-ol derivatives has been achieved by the one-pot, three-componentreactions of primary amines, aryl isothiocyanates, and 3-bromo-1,1,1-trifluoropropanone. The reactions go via symmetrical and unsymmetrical thiourea intermediates. Subsequent reactions of the products allow the synthesis of various scaffolds, including
Design, synthesis and biological evaluation of 1,2,3-triazole based 2-aminobenzimidazoles as novel inhibitors of LasR dependent quorum sensing in <i>Pseudomonas aeruginosa</i>
(autoinducers) to recognize their population density. Inhibiting this quorum sensing signalling pathway is one of the potential methods to treat bacterial infection. 2-Aminobenimdazoles are reported to be the strongest inhibitors of quorum sensing against wild-type P. aeruginosa. 1,2,3-Triazole based acyl homoserine lactones are found to be good inhibitors of the quorum sensing LasR receptor. Hence, in our
细菌通过称为群体感应的信号通路调节其表型、生长和种群。在此过程中,细菌产生信号分子(自诱导剂)来识别其种群密度。抑制这种群体感应信号通路是治疗细菌感染的潜在方法之一。据报道,2-氨基苯并咪唑是野生型铜绿假单胞菌群体感应最强的抑制剂。 1,2,3-三唑基酰基高丝氨酸内酯被发现是群体感应 LasR 受体的良好抑制剂。因此,在我们目前的研究中,合成了 40 种 1,2,3-三唑基 2-氨基苯并咪唑,并使用 IR、NMR、MS 和元素分析进行了表征。开发了N- (1 H-苯并[ d ]咪唑-2-基)-2-(4-壬基-1 H -1,2,3-三唑-1-基)乙酰胺( 6d )的单晶。筛选所有最终化合物对铜绿假单胞菌的体外群体感应抑制活性。通过测量绿色荧光蛋白的产生来确定表达 LasR 的铜绿假单胞菌MH602 报告菌株的群体感应抑制活性。标题化合物中, N- ( 1H-苯并[ d ]咪唑-2-基)-2-(4-(4-氯苯基)-1H

isoxazole-linked benzothiazole/benzoxazole derivatives were synthesized and evaluated for their anticancer activity against human cancer cell lines, such as HeLa (cervical), and A549 (lung) cell lines, with HEK-293 cell line used as a control. Among them, conjugates 8a, 8f, 13g, 13h and 13j displayed significant cytotoxic activity against human cancer cell lines. Furthermore, these active conjugates induced
