Crenigacestat (LY3039478) 是具有口服活性的Notch和γ-secretase的抑制剂,其在多种肿瘤细胞中的IC50为 ~1nM。
生物活性 | Crenigacestat (LY3039478) is an orally activeNotchandγ-secretaseinhibitor, with anIC50of 1 nM in most of the tumor cell lines tested[1][2][3][4]. |
体外研究 (In Vitro) | Crenigacestat (100 nM) exhibits anti-cancer activity in K07074 cells (a primary mouse liver tumor cell line)[2]. Crenigacestat (LY3039478) decreases expression of Myc and cyclin A1 (part of the NOTCH-driven proliferative signature) in murine and human model systems. Crenigacestat (LY3039478) treatment also leads to G0/G1 cell cycle arrest in CCRCC cells[3].
Cell Viability Assay[2]. Cell Line: | K07074 cells. | Concentration: | 100 nM. | Incubation Time: | 24-96 hours. | Result: | Effectively reduced the growth of K07074 cells. |
|
体内研究 (In Vivo) | Crenigacestat (8 mg/kg, oral gavage three times a week) resulted in significantly increases survival and delayed tumor growth in independent cohorts of mice demonstrating in vivo efficacy in CCRCC[3].
Animal Model: | CCRCC xenografts were established in NOD-scid IL2R null mice with subcutaneous implantation using the 769-P cell line[3]. | Dosage: | 8 mg/kg. | Administration: | Oral gavage three times a week. | Result: | Resulted in increased overall survival when compared with vehicle control in CCRCC xenografts. |
