Frutinone A, a biologically active ingredient of an antimicrobial herbal extract, demonstrates potent inhibitory activity towards the CYP1A2 enzyme. A three‐step total synthesis of frutinone A with an overall yield of 44 % is presented. The construction of the chromone‐annelated coumarin core was achieved through palladium‐catalyzed CH carbonylation of 2‐phenolchromones. The straightforward synthetic
Frutinone A是一种抗微生物草药提取物的生物活性成分,对CYP1A2酶表现出有效的抑制活性。提出了三步完全合成果胶酮A的方法,总产率为44%。色酮-稠合的香豆素芯的构造通过实现钯催化Ç H的2-phenolchromones羰基化。简单的合成路线可在果胶酮A核心周围轻松替换,因此可以快速探索衍生物的结构-活性关系(SAR)谱。测定了合成的果胶酮A衍生物对CYP1A2的抑制活性,并且十种化合物对CYP1A2酶表现出一到两位数的纳摩尔抑制活性。
