Agerafenib (RXDX-105, CEP-32496) 是一种高度有效的BRAF(V600E/WT)和c-Raf抑制剂,Kd为14 nM/36 nM和39 nM,适度有效作用于Abl-1, c-Kit, RET (c-RET), PDGFRβ和VEGFR2,对MEK-1, MEK-2, ERK-1和ERK-2具有微弱的亲和力。
Agerafenib (CEP-32496; RXDX-105) 是一种口服高效的 BRAFV600E 抑制剂,Kd 为 14 nM。
CEP-32496是一种高效的和口服有效的BRAF突变体V600E、野生型BRAF和c-Raf抑制剂,Kd值分别为14 nM、36 nM和39 nM。
除了BRAF(V600E)之外,CEP-32496对野生型BRAF和相关的CRAF表现出高的结合亲和力,对某些可以用于疾病治疗的受体酪氨酸激酶,如Abl-1、c-Kit、RET、PDGFR- β和VEGFR-2也具有结合能力。CEP-32496对于MAPK信号转导途径的RAF成员具有选择性,但是对MAPK通路的其他关键激酶没有显著亲和力,包括MEK-1、MEK-2、ERK-1和ERK-2。这表明,观察到的细胞活性主要是通过抑制BRAF(V600E)驱动的。与表达野生型BRAF的肿瘤细胞系相比,CEP-32496对表达BRAF突变体的肿瘤细胞系具有选择性的细胞毒性,这个实验结果进一步支持了上述论点。
在Colo-205肿瘤异种移植小鼠中,口服给药CEP-32496,显著抑制了肿瘤细胞裂解物中的pMEK。
Information
Agerafenib (RXDX-105, CEP-32496) is a highly potent inhibitor ofBRAF(V600E/WT)andc-RafwithKdof 14 nM/36 nM and 39 nM, also potent to Abl-1, c-Kit, Ret (c-Ret), PDGFRβ and VEGFR2, respectively; insignificant affinity for MEK-1, MEK-2, ERK-1 and ERK-2. Phas
In vitro
CEP-32496 inhibits A375 cell (BRAFV600E) proliferation with EC50 of 78 nM. CEP-32496 exhibits more sensitive cytotoxicity for tumor cell lines (A375, SK-MEL-28, Colo-205, Colo-679, and HT-144) expressing mutant BRAF than those expressing wild-type BRAF (HCT116, Hs578T, LNCaP, DU145, and PC-3). CEP-32496 inhibits mitogen-activated protein (MAP)/extracellular signal-regulated (ER) kinase (MEK) phosphorylation (pMEK) in human melanoma (A375) and colorectal cancer (Colo-205) cell lines with IC50 of 78 nM and 60 nM, respectively.
In vivo
CEP-32496 exhibits good stability in mouse, dog, monkey, and human liver microsomal preparations with measured intrinsic clearance values of <23 (μL/min)/mg and t1/2 > 60 min in all assays. CEP-32496 (30 mg/kg, orally, BID) exhibits tumor stasis and a 40% incidence of partial tumor regressions (PRs) in Colo-205 xenograft mouse model, whereas the 100 mg/kg dose group exhibits both tumor stasis and an 80% incidence of PRs. CEP-32496 (30 mg/kg, orally, BID) leads to a 50% and 75% inhibition of normalized pMEK in tumor lysates at the 2 hours and 6 hours postdose time point, respectively, while a 55 mg/kg dose results in a 75% to 57% inhibition of pMEK at 2 hours through 10 hours post administration in Colo-205 xenograft mouse model. CEP-32496 is orally bioavailable in multiple preclinical species (>95% in rats, dogs, and monkeys). CEP-32496 (100 mg/kg) results in inhibition of pMEK and pERK and sustained tumor stasis and regressions in BRAF(V600E) colon carcinoma xenografts in nude mice.
