Based on our previous experiences with synthesis of purines, novel 2,6,9-trisubstituted purine derivatives were prepared and assayed for the ability to inhibit CDK1/cyclin B kinase. One of newly synthesized compounds designated as olomoucine II, 6-[(2-hydroxybenzyl)amino]-2-[1-(hydroxymethyl)propyl]amino}-9-isopropylpurine, displays 10 times higher inhibitory activity than roscovitine, potent and specific CDK1 inhibitor. Olomoucine 11 in vitro cytotoxic activity exceeds purvalanol A, the most potent CDK inhibitor, as it kills the CEM cells with IC50 value of 3.0 muM. (C) 2002 Elsevier Science Ltd. All rights reserved.
