CEP-32496 is a selective inhibitor of BRAFV600E with IC50 value of 669 nM [1].
BRAF is a member of Raf kinase family and plays an important role in sending signals (directing cell growth) inside cells. BRAF involves in regulating MAP kinase/ERKs signaling pathway and mutant BRAFV600E activates MAPK pathway, it has been shown that BRAF mutant BRAFV600E is correlated with several human cancers [2].
CEP-32496 is a potent BRAFV600E inhibitor and has a different selectivity with the reported BRAFV600E inhibitor RG7204. Using Ambit Kinomescan Assay, it was shown that CEP-32496 potently binding to RAF family with Kd value ranged from 14 to 39 nmol/L. When tested with a panel of BRAF mutant (A375, SK-MEL-28, Colo-679, HT-144, and Colon-205) cell lines, CEP-32496 showed a selective cytotoxicity profile against tumor cell lines with V600E mutant while had no effect on wild type cell lines (HCT116, Hs578T, LNCaP, DU145, PC-3) [1]. CEP-32496 treatment exhibited high cytotoxicity against human tumor cell lines with expression of BRAFV600E while had little effect on wild type BRAF expressed cell lines [2].
In nude mice model with Colo-205 tumor cells subcutaneous xenograft, oral administration of CEP-32496 significantly inhibited pMEK normalization, induced tumor stasis (40%) while control group did not have this phenomenon in a dose of 30 mg/kg [1].
CEP-32496 also inhibits MEK phosphorylation with IC 50 value of 60 nM [1].

Identification of 1-(3-(6,7-dimethoxyquinazolin-4-yloxy)phenyl)-3-(5-(1,1,1-trifluoro-2-methylpropa n-2-yl)isoxazol-3-yl)urea hydrochloride (CEP-32496), a highly potent and orally efficacious inhibitor of V-RAF murine sarcoma viral oncogene homologue B1 (BRAF) V600E.[Pubmed:22168626]

The Ras/RAF/MEK/ERK mitogen-activated protein kinase (MAPK) signaling pathway plays a central role in the regulation of cell growth, differentiation, and survival. Expression of mutant BRAF(V600E) results in constitutive activation of the MAPK pathway, which can lead to uncontrolled cellular growth. Herein, we describe an SAR optimization campaign around a series of quinazoline derived BRAF(V600E) inhibitors. In particular, the bioisosteric replacement of a metabolically sensitive tert-butyl group with fluorinated alkyl moieties is described. This effort led directly to the identification of a clinical candidate, compound 40 (CEP-32496). Compound 40 exhibits high potency against several BRAF(V600E)-dependent cell lines and selective cytotoxicity for tumor cell lines expressing mutant BRAF(V600E) versus those containing wild-type BRAF. Compound 40 also exhibits an excellent PK profile across multiple preclinical species. In addition, significant oral efficacy was observed in a 14-day BRAF(V600E)-dependent human Colo-205 tumor xenograft mouse model, upon dosing at 30 and 100 mg/kg BID.
