Pralsetinib (BLU-667) 是一种高效的选择性RET抑制剂。Pralsetinib (BLU-667) 抑制 WT RET,RET 突变体 V804L,V804M,M918T 和 CCDC6-RET 融合,IC50分别为 0.4、0.3、0.4、0.4、0.4 nM。
生物活性 | Pralsetinib (BLU-667) is a highly potent, selectiveRETinhibitor. Pralsetinib (BLU-667) inhibits WTRET,RETmutants V804L, V804M, M918T and CCDC6-RET fusion withIC50s of 0.4, 0.3, 0.4, 0.4, and 0.4 nM, respectively[1]. |
IC50& Target | IC50: 0.4 nM (Wild type RET), 0.3 nM (RET V804L), 0.4 nM (RET V804M), 0.4 nM (RET M918T), 0.4 nM (CCDC6-RET)[1] |
体外研究 (In Vitro) | Pralsetinib (BLU-667) demonstrates more than 10-fold increased potency over approved MKIs against oncogenic RET variants and resistance mutants[1]. Pralsetinib (BLU-667) demonstrates potent activity (IC50=0.4 nM) against common oncogenic RET alterations, including RET M918T, an activating mutation found in MTC, as well as the CCDC6-RET fusion observed in PTC and NSCLC[1]. Pralsetinib (BLU-667) suppresses RET pathway signaling in a panel of RET-driven cell lines: LC2/ad (CCDC6-RET, NSCLC), MZ-CRC-1 (RET M918T, MTC), and TT (RET C634W, MTC)[1].

体内研究 (In Vivo) | Pralsetinib (BLU-667) potently inhibits growth of NSCLC and thyroid cancer xenografts driven by various RET mutations and fusions without inhibiting vascular endothelial growth factor receptor 2 (VEGFR-2)[1]. Pralsetinib (BLU-667) shows dose dependent activity against both KIF5B-RET Ba/F3 and KIF5B-RET V804L Ba/F3 allograft tumors with doses as low as 10 mg/kg twice-daily[1].
