Abstract:Cruentaren A is a natural product that exhibits potent antiproliferative activity against various cancer cell lines, yet its binding site within ATP synthase remained unknown, thus limiting the development of improved analogues as anticancer agents. Herein, we report the cryogenic electron microscopy (cryoEM) structure of cruentaren A bound to ATP synthase, which allowed the design of new inhibitors through semisynthetic modification. Examples of cruentaren A derivatives include a trans-alkene isomer, which wa… Show more
