Inhibition Studies of Naturally Occurring Terpene based Compounds with Cyclin-Dependent Kinase 2 Enzyme

Abstract

Sunil H Ganatra and Amita S Suchak

The knowledge of the molecular basis of carcinogenesis has helped to discover new, less toxic chemotherapy agents. At present, considerable attention has been focused on identifying the molecular level interactions of naturally occurring Terpene based substances, capable of inhibiting target enzymes. CDKs enzymes are known as cell regulators in eukaryotic cell cycle. In finding new anti-cancer agents, CDKs are used as target enzymes, particular among them are CDK2 enzymes. Computer based Chem-office and Autodock molecular modeling tools used to understand the ways with which Terpene based natural products interacts with Cyclin-dependent kinase 2 (CDK2). Using in-silico techniques, the binding energy between ligands and receptor enzyme are calculated in the form of ΔG in Kcal.mol-1. The reported binding energies for series of molecules are ranging from -7.96 to -16.62 Kcal.mol-1. The negative docking energies and a few hydrogen bonds between ligand and receptor enzyme support the affinity of Terpene based compounds with selected enzyme. Number of hydroxyl groups present in ligand enhances the interaction strength and stability of complex. The finding confirms the affinity of Terpene based natural products as CDK2 inhibitor.
