Description

Leptomycin is a polyketide antibiotic initially produced by Streptomyces. Leptomycin exhibits anticancer and antifungal activity. Leptomycin inhibits CRM1, preventing nuclear export of proteins. In lung cancer cells, leptomycin induces G1 phase cell cycle arrest; in cervical carcinoma cells, leptomycin increases activation of p53, inducing apoptosis.
