Featuring the dendrimer‐like properties, the cross‐linked small‐molecule micelles (cSMs) have been shown to be a good alternative to dendrimers in many applications. Following this trend, herein the copper(I)‐chelated cross‐linked cyclen micelles (CuI@cCMs) were created as a nanocatalyst for azide‐alkyne cycloaddition. Both alkynes and azides with diverse structures performed with excellent reactivity
交联的小分子胶束(cSM)具有树状聚合物的特性,在许多应用中已被证明是树状聚合物的良好替代品。遵循这种趋势,在这里,铜(I)螯合的交联环胶束(Cu I @cCMs)被创建为叠氮化物-炔烃环加成反应的纳米催化剂。在百万分之几(ppm)的催化剂用量下,具有多种结构的炔烃和叠氮化物在水中均具有出色的反应活性。循环实验表明,纳米催化剂多次重复使用后,催化效率仅略有下降。重要的是,Cu I cCMs可以轻松进入细胞并进行细胞内催化以点燃和/或杀死癌细胞。
Clubbed [1,2,3] triazoles by fluorine benzimidazole: A novel approach to H37Rv inhibitors as a potential treatment for tuberculosis
A Novel Clubbed [1,2,3] triazoles with. uorine benzimidazole series of H37Rv strain inhibitors, potentially useful for the treatment of tuberculosis is disclosed on the basis of promising results of preliminary antimicrobial study. Evaluation of the SAR of substitution within these series has followed the identi. cation of a range of compounds. Some of the derivatives are under further evaluation showing better considerable activity compared to rifampin. (C) 2008 Elsevier Ltd. All rights reserved.
