CYCLIN A BINDING GROOVE INHIBITOR ACE-ARG-LYS-LEU-PHE-GLY
OverviewOverview
Inhibition of cyclin A- and cyclin E-associated cyclin-dependent kinase-2, (CDK2) activities is an effective way of selective induction of apoptotic, cell death via the E2F pathway in tumour cells. The cyclin groove, recognition motif (CRM) in the natural CDK-inhibitory (CDKI) tumour, suppressor protein p27KIP1 was used as the basis for the design and, synthesis of a series of cyclic peptides whose biological activity and, structural characterisation by NMR and X-ray crystallography is reported., Whereas linear p27KIP1 sequence peptides were comparatively ineffective, introduction of side chain-to-tail constraints was found to be productive., An optimal macrocyclic ring size for the conformational constraint was, determined, mimicking the intramolecular H-bonding system of p27., Molecular ...
