KPT-330, analog of KPT-185, is a selective inhibitor of CRM1 [1].
Chromosomemaintenance protein 1 (CRM1) is a nuclear export receptor involved in the active transport of transcription factors, cell-cycle regulators, tumor suppressors and RNA molecules. In cancer, CRM1 is overexpression and overactive transport [1].
KPT-330 is an orally bioavailable and selective CRM1 inhibitor. In kidney cancer (RCC) cells, KPT-330 inhibited CRM1 and increased nuclear localization of p21. Then, KPT-330 induced apoptosis and inhibited cells growth [2]. In human non-small cell lung cancer (NSCLC) cells, KPT-330 inhibited cell proliferation and induced the expression of apoptosis-related proteins and cell cycle arrest [3].
In mice bearing MiaPaCa-2 xenograft model, KPT-330 (20 mg/kg) significantly inhibited tumor growth without significant toxicity or body weight loss. Also, KPT-330 increased PAR-4, pro-apoptotic Bax, cleaved PARP and caspase-3. These results suggested that KPT-330 induced apoptosis by the activation of PAR-4 signaling [1]. In mice bearing human NSCLC xenografts, KPT-330 significantly inhibited tumor growth [3].
