Abstract

In this study, binding interactions between methasterone and bovine serum albumin (BSA) were analyzed using spectroscopic techniques and molecular docking. UV absorption spectroscopy showed the formation of a ground-state complex between methasterone and bovine serum albumin (BSA). Thermodynamic parameters from fluorometric analysis indicated that the hydrogen bonding and van der Waal forces were the main interacting forces between the complex and the reaction was found to be spontaneous. Molecular docking further validated it. Nano differential scanning fluorimetry showed the protein was found to be more thermally stable in the presence of methasterone. Circular dichroism spectroscopy revealed slight reduction in the helicity after binding with methasterone suggesting conformational changes to promote binding. As no prior information exists on the binding interactions between methasterone and BSA, this study provides insights into methasterone-BSA interactions, which can serve as a foundation for future investigations into its pharmacological properties.

期刊介绍： STEROIDS is an international research journal devoted to studies on all chemical and biological aspects of steroidal moieties. The journal focuses on both experimental and theoretical studies on the biology, chemistry, biosynthesis, metabolism, molecular biology, physiology and pharmacology of steroids and other molecules that target or regulate steroid receptors. Manuscripts presenting clinical research related to steroids, steroid drug development, comparative endocrinology of steroid hormones, investigations on the mechanism of steroid action and steroid chemistry are all appropriate for submission for peer review. STEROIDS publishes both original research and timely reviews. For details concerning the preparation of manuscripts see Instructions to Authors, which is published in each issue of the journal.
