Abstract:
The design, synthesis and biological activity of a series of non-planar dihydro-beta-carboline and beta-carboline-based derivatives of the toxic anticancer agent fascaplysin is presented. We show these compounds to be selective inhibitors of CDK4 over CDK2 with an IC50 (CDK4-cyclin D1) = 11 micromol for the best compound in the series 4d. The crystallographic analysis of some of the compounds synthesised (3b/d and 4a-d) was carried out, in an effort to estimate the structural similarities between the designed inhibitors and the model compound fascaplysin.

M-Cdk Drives Transition Into Mitosis
Cyclin-dependent kinases, or Cdks, work in concert with cyclins to control cell cycle transitions. M-Cdk, a complex of Cdk1 bound to M cyclin, is a well-known example of this coordinated control that drives the transition from the G2 to the M phase.

Two states at the origin of replication
In eukaryotes, the initiation of replication occurs at many sites on the chromosomes, called the origins of replication.
