Product Name :
R547
Description:
R547 is orally bioavailable diaminopyrimidine cyclin-dependent kinase inhibitor (CDKI) with potential antineoplastic activity. CDKI R547 selectively binds to and inhibits CDKs, especially CDK1/cyclin B, CDK2/cyclin E, and CDK4/cyclin D1. The inhibition of CDKs results in cell cycle arrest, inhibition of tumor cell proliferation, and induction of apoptosis. Through CDK inhibition, this agent also reduces phosphorylation of the retinoblastoma (Rb) protein, thus preventing activation of transcription factor E2F and so further suppressing tumor cell proliferation. CDKs are ATP-dependent serine/threonine kinases that are important regulators of cell cycle progression and are frequently overexpressed in tumor cells.

R547 effectively inhibits the proliferation of tumor cell lines independent of multidrug resistant status, histologic type, retinoblastoma protein, or p53 status, with IC50s R547 possessing both 5-and 6-fluoro substitution culminated in an Inhibitor with low, single-digit nanomolar potency against the CDKs(Ki=0.001, 0.003, and 0.001 μM for CDK1, CDK2, and CDK4, respectively) and excellent cellular potency (IC50=0.08 μM, HCT116 cell line).|In Vivo:|R547 administered with oral and i.v. dosing in multiple established human tumor significantly inhibits tumor activity(P R547 inhibits tumor growth up to 95% in the HCT116 human colorectal tumor xenograft model in nude mice . R547 causes significant TGI in all of the models tested when dosed orally and i.v. at or below the maximum tolerated dose. R547 inhibits phosphorylation of retinoblastoma protein in tumors at the efficacious exposures in tumor xenograft models, providing a pharmacodynamic biomarker for clinical use. R547 reported here suggests that this is a promising molecule for evaluation in the treatment of solid tumors.|References:|Berkofsky-Fessler W, et al.
