Abstract

Platinum compounds are very important to treatment of various malignant tumors. However, prediction of platinum-binding sites is very hard to be made. Nevertheless, hydrolysis of leaving groups bounded to platinum compounds plays an important role in delivering platinum to a target molecule. Herein, a study in silico provides an understanding of the molecular surface in atomic level of three-dimensional structure of cisplatin and transplatin and their binding-sites in order to offer some insights in drug designing. The goal of this work was to implement a new approach based on geometric and physicochemical parameters to find platinum-binding sites using parallel computing algorithms for graphics processing units (GPUs).
