Abstract: Cyclin dependent kinases (CDKs) act as potential therapeutic targets in cancer disease and automated docking was performed on a set of 144 Telmisartan analogues containing imidazole rings which are reported as angiotensin II receptor antagonists. Molecular docking analysis of CDKs 2, 4 and 5 resulted in better binding affinities within the active site region of each CDK. Compounds 122 and 121 are selective towards CDK2 and CDK4 inhibitions, whereas compounds 131, 133 and 134 were found to be selective towards CDK4 and CDK5 inhibitions. Compound 27 was found to be highly selective towards CDK2 with binding affinity of −201.547 kcal/mol when compared with dock scores of CDK4 and CDK5 (−195.687 and −170.421 kcal/mol). On the basis of geometric orientation of docked poses within active sites of CDKs, it was observed that the presence of triazole and tetrazole groups on these compounds is responsible for better inhibitory activities.
