Within the context of graph theory, a topological index serves as a numerical descriptor that encapsulates the physicochemical properties of a chemical graph. These are particularly useful in cheminformatics, where they serve as a compact representation of the molecule's structure, capturing various physicochemical properties such as molecular size, shape, branching, and connectivity. These studies are pivotal in the initial phases of drug development, facilitating the identification and optimization of potential pharmaceutical drugs. In this paper, we discuss a range of distance-based topological indices applied to a selection of tricyclic anti-depressant drugs aiming to understand their physicochemical characteristics. Additionally, the quantitative structure-property relationship (QSPR) analysis is explored for distance-based topological indices aim to predict how changes in chemical structure might influence the efficacy and potency of these drugs.
在图论的背景下,拓扑指数作为一种数值描述符,用于概括化学图的物理化学性质。这些指数在化学信息学中特别有用,在那里它们作为分子结构的紧凑表示,捕捉各种物理化学性质,如分子大小、形状、分支和连通性。这些研究在药物开发的初始阶段至关重要,有助于识别和优化潜在的药物。在本文中,我们讨论了一系列基于距离的拓扑指数,应用于选择的三环抗抑郁药物,旨在了解它们的物理化学特征。此外,还探讨了基于距离的拓扑指数的定量结构-性质关系(QSPR)分析,旨在预测化学结构的变化如何影响这些药物的疗效和效力。
