Interaction of Noscapine with Human Serum Albumin (HSA): A Spectroscopic and Molecular Modelling Approach

Noscapine, an opium derived anticancer agent manifests therapeutic applications and is compliant to beneficial modifications. In this paper, we study its interaction with human serum albumin (HSA) by different spectroscopic methods including UV-vis, fluorescence, circular dichroism and thermal denaturation and molecular docking. Binding and thermodynamics parameters support a feasible interaction of Nos-HCl with HSA. Further, type of interactions between Nos-HCl and HSA were also elucidated. The energy transfer between HSA and Nos-HCl was analyzed by Forster mechanism and lifetime measurements. Additionally, it was shown that Nos-HCl binds HSA in subdomain IIIA which constitute the drug binding Sudlow’s Site II. Preliminary results for binding site were deciphered via the site marker competitive experiments which were then confirmed using molecular docking analysis.
