Coxsackievirus B

A series of bioactive benzimidazoles were theoretically evaluated for their effect against enteroviruses, particularly coxsackievirus B and coxsackievirus A16. The structure-activity relationship allowed to deduce a very efficient model that can be used as a reference for the synthesis of compounds against this type of virus. The model used is essentially based on the RML and NN method, and its validation was carried out using cross-validation. The results obtained by molecular docking and ADMET of compound 9 as an inhibitor of enterovirus A16 give the proposal of the drug of this series.

Background: Microtubules are dynamic filamentous cytoskeletal structures which play several key roles in cell proliferation and trafficking. They are supposed to contribute in the development of important therapeutic targeting tumor cells. Chalcones are important group of natural compounds abundantly found in fruits & vegetables that are known to possess anticancer activity. We have used QSAR and docking studies to understand the structural requirement of chalcones for understanding the mechanism of microtubule polymerization inhibition. Methods: Three dimensional (3D) QSAR (CoMFA and CoMSIA), pharmacophore mapping and molecular docking studies were performed for the generation of structure activity relationship of combretastatin-like chalcones through statistical models and contour maps. Results: Structure activity relationship revealed that substitution of electrostatic, steric and donor groups may enhance the biological activity of compounds as inhibitors of microtubule polymerization. From the docking study, it was clear that compounds bind at the active site of tubulin protein. Conclusion: The given strategies of modelling could be an encouraging way for designing more potent compounds as well as for the elucidation of protein-ligand interaction.
