Leptomycin B is an inhibitor of the nuclear export of proteins which acts by binding directly to and inhibiting CRM1/exportin-1. Leptomycin B inhibits the nuclear export of the HIV regulatory protein Rev and stabilizes p53, showing antiviral, antibiotic, antifunal and antitumor in vitro and in vivo.

描述 | Leptomycin B (CI 940; LMB) is a potent inhibitor of protein nuclear export, inactivating CRM1/exportin 1 through covalent modification at a cysteine residue. It has been identified as a potent antifungal antibiotic that impedes the eukaryotic cell cycle[1]. |
Animal study | However, Leptomycin B's in vivo tolerance is limited, with a maximum tolerated dose (MTD) of 2.5 mg/kg when administered intravenously in HCT-116 tumor-bearing mice, indicating challenges in its therapeutic application due to off-target effects. Despite its potent inhibition of CRM1, the limited in vivo efficacy suggests the need for further refinement in targeting strategies to improve tolerance and efficacy[4]. |
