Chemical graph theory and topological indices are key tools in the study of molecular structures and their properties. This research explores anticancer drugs using neighborhood degree-based topological indices and compares their efficacy through regression and machine learning models. The QSPR approach is applied to 15 anticancer drugs by constructing neighborhood-based molecular graphs, and calculating their respective topological indices. Regression models like quadratic, cubic, and random forest are employed to predict response metrics including like boiling point, refractivity, and surface area of the drugs. Comparative studies indicate that quadratic models provide better predictive performance then their cubic counterparts in most scenarios. Random forest models also demonstrate satisfactory accuracy with smaller error bounds. The present findings highlight the usefulness of topological indices in chemoinformatics and their application in predicting drug response.
化学图论和拓扑指数是研究分子结构及其性质的关键工具。本研究利用基于邻域度的拓扑指数探索抗癌药物,并通过回归和机器学习模型比较它们的疗效。通过构建基于邻域的分子图并计算其各自的拓扑指数,将定量构效关系(QSPR)方法应用于15种抗癌药物。采用二次、三次和随机森林等回归模型来预测包括药物沸点、折射率和表面积等响应指标。比较研究表明,在大多数情况下,二次模型比三次模型具有更好的预测性能。随机森林模型也显示出令人满意的准确性,误差范围更小。目前的研究结果突出了拓扑指数在化学信息学中的有用性及其在预测药物反应中的应用。
