RGB-286638 is a small-molecule multi-targeted cyclin-dependent kinase (CDK) inhibitor with IC50 of 1-5 nM for cyclin T1-CDK9, cyclin B1-CDK1, cyclin E-CDK2, cyclin D1-CDK4, cyclin E-CDK3, and p35-CDK5.
RGB-286638 is less potent against cyclin H-CDK7 and cyclin D3-CDK6.
RGB-286638 also inhibits several tyrosine and serine/threonine non-CDK enzymes with IC50 of 1-50 nM, i.e. GSK-3β, TAK1, AMPK, Jak2, MEK1.
RGB-286638 potently inhibits cell growth of human p53-wt (MM.1S, MM.1R, and H929) and p53-mutant (U266, OPM1, and RPMI) MM cells with EC50 of 20-70 nM.
RGB-286638 (50nM) reduces the phosphorylation of Rb at S807/811 in MM.1S and MM.1R cells, but has no effects on p-Rb S780.
RGB-286638 induces cytotoxicity in p53 knockdown MM.1S, exhibits anti-MM activity in vivo.
