for azidation of aromatic compounds25 by a diazotization-azidation sequence. In the present work, we have developed an efficient and simple method for the diazotization and azidation of aromatic amines using the acidic ionic liquid N-methyl-2-pyrrolidonium bisulfate ([H-NMP]HSO4) as solvent and a novel proton source for the diazotization process at room temperature. The diazotization of various aryl
New 1-aryl-4-(β-D-fructopyranos-3-O-yl)methyl-1H-1,2,3-triazole derivatives have been synthesized by a CuAAC reaction and their antibacterial and antifungal activity has been evaluated. Some of the derivatives showed remarkable in vitro antibacterial activity against Staphylococcus aureus, Staphylococcus epidermidis, Pseudomonas aeruginosa, and Klebsiella pneumoniae and moderate antifungal activity

implicated in the etiology and progression of metabolicdisorders. Although lines of genetic evidence suggest that blockage of this pathway yields favorable outcomes in treating such ailments, few inhibitors have been used to validate the promising genetic findings. Here, we synthesized and characterized a novel class of triazole-based Wnt/β-catenin signaling inhibitors and assessed their effects on energy

Abstract The synthesis of a novel series of 3-functionalised benzenesulfonamides incorporating phenyl-1,2,3-triazole with an amide linker was achieved by using the “click-tail” approach. The new compounds, including the intermediates, were assayed as inhibitors of human carbonicanhydrase (CA, EC 4.2.1.1) isoforms hCA I and II (cytosolic isoforms) and also for hCA IV and IX (transmembrane isoforms)
抽象的 通过使用“点击尾巴”方法,可以合成一系列新的3-官能化的苯磺酰胺,这些苯基磺酰胺结合了苯基-1,2,3-三唑和一个酰胺连接基。以乙酰唑醇为标准药物,测定了包括中间体在内的新化合物作为人类碳酸酐酶(CA,EC 4.2.1.1)同工型hCA I和II(胞质同工型)的抑制剂,以及hCA IV和IX(跨膜同工型)的抑制剂。这些化合物中的大多数对所有这些同工型均表现出优异的活性。hCA I被K i s抑制在50.8–966.8 nM的范围内,而青光眼相关的hCA II被K i s抑制在6.5–760.0 nM的范围内。K i抑制同工型hCA IVs的范围为65.3–957.5 nM,而与肿瘤相关的缺氧诱导的hCA IX被K i s抑制的范围为30.8–815.9 nM。从结果还推断出3-官能化的-1-苯基-1,2,3-三唑氨磺酰基苯甲酰胺对抗这些同工型的结构活性关系。
