Cyclin-dependent kinases (CDKs) are central drivers of aberrant cell-cycle progression in diverse malignancies, yet the clinical utility of existing CDK inhibitors remains limited by selectivity challenges and toxicity. Here, we integrate multi-tiered computational screening to identify phytochemicals from seven ethnomedicinal plants of the Chittagong Hill Tracts, Bangladesh, with potential anticancer activity against CDK2 and CDK6. An initial library of 200 plant-derived compounds was curated from the IMPPAT 2.0 database and refined through comprehensive ADME/T profiling, yielding 17 drug-like candidates. Molecular docking revealed two molecules, Bergapten (CID 2355) and D-Camphor (CID 159055) as top binders, exhibiting affinities comparable to but not exceeding, native inhibitors for CDK2 (–7.93 kcal/mol and –7.14 kcal/mol) and CDK6 (–8.74 kcal/mol and –8.59 kcal/mol). MM-GBSA free-energy calculations indicated better binding interactions of Bergapten in CDK2, while moderate binding was observed for CDK6. Electronic structure analysis demonstrated stable HOMO–LUMO characteristics consistent with reduced chemical reactivity. Molecular dynamics simulations revealed better structural stability profiles, with no significant fluctuations observed for Bergapten. Collectively, these in silico results identify Bergapten as a potential drug candidate targeting CDK2/CDK6 with favorable pharmacokinetic properties. However, experimental validation is required to confirm its biological activity and therapeutic relevance.
