LEPTOMYCIN B FROM STREPTOMYCES SP Usage And Synthesis
▼
▲
Uses
Leptomycin B is the dominant and most studied member of the leptomycin class, isolated from selected Streptomyces strains. Leptomycin B is a nanomolar active and specific nuclear export inhibitor. Its target is CRM1/exportin1, a protein in the nuclear export sequence (NES). Proteins affected include c-Abl, cyclin B1, HIV-1 Rev, IκB, MPF, MAP/ERK, MDM2/p53, NF-κB/IκB7 and PKA. Leptomycin B inhibits export of many RNAs, e.g. COX-2 and c-FOS mRNA. Leptomycin B also shows antifungal and antibacterial and potent antitumour activities.
