INHIBITION STUDIES OF TERPENE BASED NATURAL PRODUCTS WITH CYCLIN-DEPENDENT KINASE 4 (CDK4 MIMIC CDK2)
AbstractCyclin dependent kinases (CDKs) are known as cell cycle regulators in eukaryotic cell cycle. Different CDKs (CDK2, CDK4 etc.) are having structure homology among them. Using computer based molecular modeling tools, interactions between naturally occurring terpene based compounds with crystal structure of CDK4 mimic CDK2 enzyme having PDB ID : 1GII. Using In-silico techniques, the binding energies between terpene based compounds and receptor enzymes are calculated in the form of ΔG in kcal/mol. The reported binding energies for series of molecules are ranging from –5.35 to –13.20 kcal/mol. The negative docking energies and a few hydrogen bonds between selected ligands and receptor enzyme support the affinity of Terpene based compounds with CDK4 mimic CDK2 enzymes. It is also found out that those compounds having carbon atoms 30-31 interacts better with enzyme, whereas larger size compounds having carbon atoms higher than 40 show weak interactions. It is concluded that Tri-terpene class of compounds are the best CDK4 mimic CDK2 inhibitors.
