Abstract:

Background: The endogeneous antioxidant mechanism often fails to combat the huge free radical overload necessitating external antioxidant supplementation. Thus identification and definite structural manipulation of the naturally available antioxidant derivatives using in silico methodology help to design new moieties with improved therapeutic potential.

Objective: The present work has been performed with the aim to identify the essential molecular fragments that contribute to the antioxidant property of the coumarin derivatives.

Method: In this work three separate chemometric methods were utilised to highlight the structural requisites of the coumarin derivatives.

Results: The QSAR model thus developed helps to highlight the prime molecular fragments, while the 3D pharmacophore model denotes the features constituting the biological pharmacophore for the coumarin derivatives. Again, the HQSAR contour signifies the relative contribution of the different molecular fragments.

Conclusion: In silico techniques thus adapted in the present work highlight a significant paradigm in the process of screening and designing therapeutically active antioxidant moieties.

Keywords: Antioxidants, coumarin, QSAR, 3D pharmcophore, HQSAR.
