产品详情
生物活性：
Naporafenib (LXH254) is a potent, selective, orally active, type II BRAF and CRAF inhibitor, with IC50 values of 0.072 and 0.21 nM against CRAF and BRAF, respectively.
体内研究：
Treatment with Naporafenib (Compound A) generates tumor regression in several KRAS-mutant models including the NSCLC-derived Calu-6 (KRAS Q61K) and NCI-H358 (KRAS G12C). Naporafenib exhibits efficacy in numerous MAPK-driven human cancer cell lines and in xenograft tumors representing model tumors harboring human lesions in KRAS, NRAS and BRAF oncogenes.Naporafenib shows significant antitumor activity in models harboring BRAF mutations either alone or coincident with either activated NRAS or KRAS, and RAS mutants lacking ARAF are more sensitive to Naporafenib.Animal Model:Outbred athymic (nu/nu) female mice and SCID Beige mice; BRAF-, NRAS-, and KRAS-mutant xenograft models, as well as a RAS/RAF wild-type model
Dosage:100 mg/kg
Administration:Orally, daily
Result:Significantly decreased tumor volume in models harboring BRAF mutations either alone or coincident with either activated NRAS or KRAS, slightly decreased tumor volume in KRAS model.
体外研究：
Naporafenib (Compound A) is an adenosine triphosphate (ATP)-competitive inhibitor of BRAF (also referred to herein as b-RAF or b-Raf) and CRAF (also referred to herein as c-RAF or c- Raf) protein kinases. Throughout the present disclosure, Naporafenib is also referred to as a c-RAF (or CRAF) inhibitor or a C-RAF/c-Raf kinase inhibitor. In cell-based assays, Naporafenib has demonstrated anti-proliferative activity in cell lines that contain a variety of mutations that activate MAPK signaling. Moreover, Naporafenib is a Type 2 ATP -competitive inhibitor of both B-Raf and C-Raf that keeps the kinase pocket in an inactive conformation, thereby reducing the paradoxical activation seen with many B-Raf inhibitors, and blocking mutant RAS-driven signaling and cell proliferation.Naporafenib (0-10 μM, 1 h) inhibits both monomeric and dimeric RAF and promotes RAF dimer formation.Naporafenib has reduced ability to suppress MAPK signaling driven by ARAF and further that the contribution of ARAF to MAPK signaling increases in the absence of CRAF expression.Naporafenib shows more sensitivity when cells lack ARAF.
