KPT-330
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].

|
Applications |
KPT-330(10 mg/kg) showed antitumour activity against human non-small cell lung cancer. Moreover, KPT-330 potentiated the antitumor activity of gemcitabine in human pancreatic cancer through inhibition of tumor growth, induction of apoptosis, and depletion of the antiapoptotic proteins. |
|
Other notes |
Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |
