Abstract

The introduction of an aryl ring onto the 4-position of the C-6 benzyl amino group of the CDK inhibitor roscovitine (2), maintained the potent CDK inhibition demonstrated by roscovitine (2) as well as greatly improving the antiproliferative activity. A series of C-6 biarylmethylamino derivatives was prepared addressing modifications on the C-6 biaryl rings, N-9 and C-2 positions to provide compounds that displayed potent cytotoxic activity against tumor cell lines. In particular, derivative 21h demonstrated a >750-fold improvement in the growth inhibition of HeLa cells compared to roscovitine (2).
