Design, synthesis and biological evaluation of new tryptamine and tetrahydro-beta-carboline-based selective inhibitors of CDK4.


PMID 18650093

Abstract

We present the design, synthesis and biological activity of a library of substituted (biphenylcarbonyl)-tryptamine and (biphenylcarbonyl)-tetrahydro-beta-carboline compounds related to the natural product fascaplysin, as novel inhibitors of CDK4/cyclin D1. We show all these molecules, prepared using the Suzuki-Miyaura reaction, being selective inhibitors of CDK4 over CDK2. The most active compounds have a CDK4 IC(50) in the range 9-11 microM, three of them containing the para-biphenyl plus para-substituents supporting the existence of a pi-stacking pocket within the active site of CDK4.
