Docking and simulation studies on cyclin D/CDK4 complex for targeting cell cycle arrest in cancer using flavanone and its congener.

Flavanone compounds are naturally occurring phytochemicals present in most of citrus fruits reported to be a potential anticancer moiety as it majorly participates in the inhibition of the cell cycle, apoptosis, and angiogenesis. Because of poor bioavailability, natural flavanones were not used as therapeutic targets so flavanone congeners were prepared by modifying at B-functional group using compound libraries such as PubChem Database. Cyclin-dependent kinase is primarily activating the cell cycle and potentiating the M phase, in order to control the cell cycle in cancer cyclin-dependent pathway was targeted and potential cyclin D/CDK4 receptor protein was retrieved from Protein Data Bank (PDBID:2W9Z).
