Synthesis and biological evaluation of (±)-hippolachnin and analogs

J Antibiot (Tokyo). 2019 Jun;72(6):375-383. doi: 10.1038/s41429-019-0176-x. Epub 2019 Apr 12.

Abstract

Due its unique structure and its reported potent antifungal activity, the marine polyketide hippolachnin A (1) has attracted much attention in the synthetic community. Herein, we describe the development of a concise, diversifiable and scalable synthesis of the racemic natural product, which serves as a platform for the generation of bioactive analogues. Biological testing of our synthetic material did not confirm the reported antifungal activity of hippolachnin A but unraveled moderate activity against nematodes and microbes.
