originally proposed 2-(1 H-indol-3-yl)-4 H-3,1-benzoxazin-4-one structure of the alkaloid cephalandole A (1) led to a structural revision, and the isolated natural product has now been identified as the previously known compound 3-(1 H-indol-3-yl)-2 H-1,4-benzoxazin-2-one (7). The structural assignment was corroborated by detailed NMR studies. A short synthesis of the related natural compound cephalandole
Identification of 5-[5-cyano-1-(pyridin-2-ylmethyl)-1H-indole-3-carboxamido] thiazole-4-carboxylic acid as a promising dual inhibitor of urate transporter 1 and xanthine oxidase
In combination with allopurinol, tranilast is used as an urate transporter 1 (URAT1) inhibitor for the treatment of hyperuricemia, but its structure-activity relationship concerning URAT1 inhibitory activity is rarely studied. In this paper, analogs – were designed and synthesized using scaffold hopping strategy on the basis of tranilast and the privileged scaffold indole. Then, URAT1 activity was
