Abstract

Efficient R-group exploration in the vast chemical space, enabled by increasingly available building blocks or generative AI, remains an open challenge. Here, we developed an enhanced Free-Wilson QSAR model embedding R-groups by atom-centric pharmacophoric features. Regioisomers of R-groups can be distinguished by explicitly accounting for the atomic positions. Good predictivity is observed consistently across 12 public data sets. Integrated into an open-source program, we showcase its application in performing Free-Wilson analysis as well as R-group exploration in an uncharted chemical space.

人工智能增强r -基团在药物化学中的探索
在越来越多可用的构建模块或生成式人工智能的支持下,在广阔的化学领域进行有效的r群探索仍然是一个开放的挑战。在这里,我们开发了一个增强的Free-Wilson QSAR模型,通过原子中心的药效特征嵌入r -基团。r -基团的区域异构体可以通过明确地计算原子位置来区分。在12个公共数据集中观察到一致的良好预测。集成到一个开源程序中,我们展示了它在执行Free-Wilson分析以及在未知化学空间中的r -群探索中的应用。

期刊介绍: The Journal of Chemical Information and Modeling publishes papers reporting new methodology and/or important applications in the fields of chemical informatics and molecular modeling. Specific topics include the representation and computer-based searching of chemical databases, molecular modeling, computer-aided molecular design of new materials, catalysts, or ligands, development of new computational methods or efficient algorithms for chemical software, and biopharmaceutical chemistry including analyses of biological activity and other issues related to drug discovery. Astute chemists, computer scientists, and information specialists look to this monthly’s insightful research studies, programming innovations, and software reviews to keep current with advances in this integral, multidisciplinary field. As a subscriber you’ll stay abreast of database search systems, use of graph theory in chemical problems, substructure search systems, pattern recognition and clustering, analysis of chemical and physical data, molecular modeling, graphics and natural language interfaces, bibliometric and citation analysis, and synthesis design and reactions databases.
