Chemical graphs are mathematical representations of molecular structures, where atoms are represented as vertices, while chemical bonds are depicted as edges of a graph. The chemical graphs are widely used in cheminformatics to analyze molecular properties, predict biological activity and design new drugs. A topological index (TI) in drug design is a numerical descriptor of a molecular graph that correlates its structure with biological activity and physicochemical properties. The aim of this study is to use the concepts of chemical graphs to examine the molecular characteristics and structural design of anti-HIV drugs. Secondly, we have utilized the concept of supervised machine learning to create a predictive model. Finally, we have compared the results of different machine learning algorithms such as Random Forest algorithm and XGBoost algorithm. These methods not only enhance drug effectiveness but also aid in predicting new drug candidates.
化学图是分子结构的数学表示,其中原子表示为顶点,而化学键则描绘为图的边。化学图在化学信息学中被广泛用于分析分子性质、预测生物活性和设计新药。药物设计中的拓扑指数(TI)是分子图的一种数值描述符,它将其结构与生物活性和物理化学性质相关联。本研究的目的是利用化学图的概念来研究抗HIV药物的分子特征和结构设计。其次,我们利用监督机器学习的概念创建了一个预测模型。最后,我们比较了不同机器学习算法(如随机森林算法和XGBoost算法)的结果。这些方法不仅提高了药物有效性,还有助于预测新的候选药物。
