CEP-32496 (free base) Chemical Properties,Usage,Production
Description
B-Raf is a MAP kinase kinase kinase, which functions downstream of Ras family GTPases to activate MEK1/2 and ERK1/2 signaling. Mutations of B-Raf, particularly at Val600, are common in melanomas and melanocytic nevi. CEP-32496 is a potent inhibitor of B-RafV600E (Kd = 14 nM in an in vitro binding assay). It blocks B-RafV600E-dependent phosphorylation of MEK in human melanoma A375 and colorectal cancer COLO 205 cells (IC50s = 78 and 60 nM, respectively). CEP-32496 binds kinases other than B-Raf but displays selective cytotoxicity for cells expressing B-RafV600E. It displays good oral bioavailability in rats, dogs, and monkeys and has single oral dose pharmacodynamics inhibition of both pMEK and pERK in B-RafV600E colon carcinoma xenografts in nude mice.
Uses
CEP 32496 is an orally active BRAFV600E inhibitor with selective cellular and in vivo antitumor activity.
Synthesis

1188911-77-4
1188910-76-0
A 10L Chemglass jacketed reactor, equipped with an N2 inlet/outlet, was charged with 3-[(6,7-dimethoxy-4-quinazolinyl)oxy]aniline (Compound 2, 200.0 g, 637 mmol) and phenyl (5-(1,1,1-trifluoro-2-methylpropan-2-yl)isoxazol-3-yl)carbamate (Compound 3, 177.0 g, 596 mmol). equipped with N2 inlet/outlet, 4-dimethylaminopyridine (DMAP, 2.88 g) and 4.0 L of isopropylacetic acid were added. The internal temperature of the reaction mixture was raised to 70 °C and maintained at this temperature for 9 hours. The slurry was maintained during the reaction and HPLC monitoring showed that compound 2 was completely consumed after a period of heating. Subsequently, 2.0 L of heptane was added at 70 °C and the reaction mixture was cooled to 20 °C. Stirring was continued for 1 h to precipitate the solid, filtered, and the filter cake was washed with 2.0 L of a 1:1 (v/v) isopropyl acetate/heptane solvent mixture. The resulting white solid was dried under vacuum at 55 °C and 75 mbar by N2 exhaust to give 295 g (96% yield) of form A0 product with 99.3% HPLC purity.
in vivo
Oral administration of Agerafenib (CEP-32496) to Colo-205 tumor xenograft-bearing mice results in significant inhibition of pMEK in tumor cell lysates. For instance, a single 30 mg/kg (po) dose of Agerafenib leads to a 50 and 75% inhibition of normalized pMEK in tumor lysates at the 2 and 6 h postdose time point, respectively (p<0.03), while a 55 mg/kg (po) dose resulted in a 75% to 57% (p<0.03) inhibition of pMEK at 2 through 10 h post administration, with normalization to baseline by 24 h. Agerafenib exhibits an exceptional PK profile in mouse, dog, and cynomolgus monkey. Administration of Agerafenib to beagle dogs (single dose of 1 mg/kg iv and 10 mg/kg po) results in low clearance (CL=5.0 (mL/min)/kg) and excellent bioavailability (%F=100). Similarly, in cynomolgus monkey, the administration of Agerafenib (single dose of 1 mg/kg iv and 10 mg/kg po) leads to high oral exposure due to low clearance (CL=6.7 mL/min/kg) and excellent bioavailability (%F=100)[1].
