Natural products provide the inspiration for most drugs, and marine natural products, in particular, are emerging as promising new therapeutics with new targets or mechanisms of action. Pharmacological targeting of tubulin dynamics has been a validated strategy for cancer therapy for decades, yielding structurally diverse natural products and derivatives, including paclitaxel, vincristine, maytansine, and eribulin, targeting six known and different binding sites. We discovered a chemical scaffold from marine cyanobacteria that targets a seventh tubulin binding site. We report the entire spectrum of the discovered chemical and biological novelties, including the isolation, structure determination, and chemical synthesis of the natural product, and the investigation of its mechanism of action, target identification, and binding mode elucidation at the atomic level.
天然产物为大多数药物提供灵感,尤其是海洋天然产物正逐渐成为具有新靶点或作用机制的有前途的新疗法。数十年来,药理学上针对微管动力学的靶向治疗一直是癌症治疗的验证策略,产生了结构多样的天然产物和衍生物,包括紫杉醇、长春碱、马丹霉素和依立必利,靶向六个已知且不同的结合位点。我们发现了一种来自海洋蓝藻的化学骨架,靶向第七个微管结合位点。我们报告了所发现的化学和生物新颖性的整个范围,包括天然产物的分离、结构确定和化学合成,以及对其作用机制、靶点识别和在原子水平上结合方式的阐明的调查。
