Borrelidin

Abstract

Borrelidin is an 18-membered polyketide macrolide derived from several Streptomyces species. First discovered in 1949 from Streptomyces rochei, Borrelidin shows antibacterial activity by acting as an inhibitor of threonyl-tRNA synthetase and features a nitrile moiety, a unique functionality in natural products., Borrelidin also exhibits potent angiogenesis inhibition, which was shown in a rat aorta matrix model. Other studies have been performed to show that low concentrations of borrelidin can suppress growth and induce apoptosis in malignant acute lymphoblastic leukemia cells. Borredlidin’s antimalarial activity has also been shown in vitro and in vivo.
