A topological index is a numerical value derived from the structure of a molecule or graph that provides useful information about the molecule's physical, chemical, or biological properties. These indices are especially important in chemo-informatics and QSAR/QSPR (Quantitative Structure-Activity Relationship/Quantitative Structure-Property Relationship) studies, where they are used to predict a wide range of properties without the need for experimental measurements. In essence, a topological index is a way to quantify the molecular structure in a form that can be used in mathematical models to estimate the molecule's behavior, activity, or properties. In terms of chemical graph theory and chemo-informatics, entropy-based indices quantify the structural complexity or disorder in a molecule's connectivity. These indices are useful for modeling and predicting molecular properties and biological activities. In this paper, we established a QSPR analysis of colorectal drugs between entropy indices and their physical properties and developed a relationship. Through a comprehensive analysis of these drugs, we gain essential insights into their molecular properties, which are vital for predicting their behavior and effectiveness in treating colorectal cancer. These models are compared with existing degree-based models, highlighting the superior performance of our approach. The QSPR study is performed using curvilinear regression models including linear, quadratic, cubic exponential and logarithmic models. Additionally, we propose the integration of machine learning (ML) techniques to further enhance the predictive accuracy and robustness of our models. By leveraging advanced ML algorithms, we aim to uncover more complex, non-linear relationships between topological indices and drug efficacy, potentially leading to more accurate predictions and better-informed drug design strategies.
拓扑指数是从分子或图的结构中导出的数值,它提供了有关分子物理、化学或生物学性质的有用信息。这些指数在化学信息学和QSAR/QSPR(定量构效关系/定量构性关系)研究中尤为重要,在这些研究中,它们被用于预测广泛的性质而无需进行实验测量。本质上,拓扑指数是一种以可用于数学模型的形式量化分子结构的方法,以估计分子的行为、活性或性质。就化学图论和化学信息学而言,基于熵的指数量化了分子连通性中的结构复杂性或无序性。这些指数对于建模和预测分子性质及生物活性很有用。在本文中,我们建立了熵指数与结直肠癌药物物理性质之间的QSPR分析并建立了一种关系。通过对这些药物的综合分析,我们对它们的分子性质有了重要的认识,这对于预测它们在治疗结直肠癌中的行为和有效性至关重要。将这些模型与现有的基于度的模型进行比较,突出了我们方法的优越性能。QSPR研究使用包括线性、二次、三次指数和对数模型在内的曲线回归模型进行。此外,我们建议整合机器学习(ML)技术以进一步提高我们模型的预测准确性和稳健性。通过利用先进的ML算法,我们旨在揭示拓扑指数与药物疗效之间更复杂的非线性关系,这可能会带来更准确的预测和更明智的药物设计策略。
