Capuramycin and its congeners are considered to be important lead molecules for the development of a new drug for multidrug‐resistant (MDR) Mycobacterium tuberculosis infections. Extensive structure–activity relationship studies of capuramycin to improve the efficacy have been limited because of difficulties in selectively chemically modifying the desired position(s) of the natural product with biologically
卡普拉霉素及其同系物被认为是开发治疗多重耐药 (MDR)结核分枝杆菌感染新药的重要先导分子。由于难以用生物学上感兴趣的官能团选择性地化学修饰天然产物的所需位置,因此为提高功效而对辣椒霉素进行的广泛的结构-活性关系研究受到了限制。我们通过使用源自手性(氯-4-甲氧基苯基)(氯苯基)甲醇的新保护基团,针对尿苷脲基氮和伯醇,开发了卡普拉霉素及其类似物的高效合成方法。手性非外消旋(2,6-二氯-4-甲氧基苯基)(2,4-二氯苯基)甲醇衍生物是解析外消旋-3-氨基-1,3-二氢-5-苯基-2 H ‐1的有用试剂, 4-苯二氮卓-2-酮,其( S )构型异构体在提高卡普拉霉素的杀分枝杆菌活性方面发挥着重要作用。
