Glesatinib (MGCD265) 是一种具有口服活性的,有效的MET/SMO双抑制剂。 Glesatinib 是一种酪氨酸激酶抑制剂,可拮抗非小细胞肺癌 (NSCLC) 中 P 糖蛋白介导的多药耐药性 (MDR)。
生物活性 | Glesatinib (MGCD265) is an orally active, potentMET/SMOdual inhibitor. Glesatinib, a tyrosine kinase inhibitor, antagonizesP-glycoprotein(P-gp) mediated multidrug resistance (MDR) in non-small cell lungcancer(NSCLC)[1][2]. |
体外研究 (In Vitro) | Glesatinib (MGCD265; 0.01-5 μM; for 72 hours) results in a dose-dependent inhibition of cancer cell growth and shows the low IC50value of 0.08 μM on NSCLC H1299 cells[1]. Glesatinib (0.01, 0.1, 0.5, 1 μM) significantly increases by several-fold the percentage of apoptotic cells in NSCLC H1299 cells[1]. Glesatinib has the cytotoxicity to P-gp overexpressing cancer cells KB-C2, SW620/Ad300, HEK293/ABCB1, and their parent cells KB-3-1, SW620, HEK293 cells with the IC50s fell between 5 and 10 μM[1]. Glesatinib (1, 3 μM; 120 mins) increases the intracellular [3H]-Paclitaxel accumulation and inhibits [3H]-Paclitaxel efflux in cancer cell lines overexpressing P-gp[2]. Glesatinib (0-40 μM) stimulates the ATPase activity of P-gp transporters in a dose-dependent manner[2].
Cell Proliferation Assay[1] Cell Line: | NSCLC H1299 cells | Concentration: | 0.01, 0.1, 1, 2, 5 μM | Incubation Time: | For 72 hours | Result: | Resulted in a dose-dependent inhibition of cancer cell growth and showed the lowest IC50value of 0.08 μM. |
|
体内研究 (In Vivo) | Glesatinib (MGCD265; 15 mg/kg/day; orally; 40 weeks) causes a significant decrease in tumor size[1].
Animal Model: | 4–6-week old female balb/c athymic (nu/nu) mice with HCC827 NSCLC tumor xenografts[1] | Dosage: | 15 mg/kg | Administration: | Orally; daily; 40 weeks | Result: | Caused a significant decrease in tumor size. |
