摘要

皮肤致敏是毒理学的一个关键终点,特别是在局部和透皮治疗的药物发现和开发过程中。在将新化合物纳入商业产品之前,准确评估皮肤致敏潜力对于确保其安全性和有效性至关重要。在本研究中,采用层次支持向量回归(HSVR)方案开发了定量结构-活性关系(QSAR)模型,用于定量预测直接肽反应性测定(DPRA)测量的赖氨酸耗损百分比,这是用于确定化学物质皮肤致敏潜力的关键因素之一。结果表明,HSVR模型在训练集、测试集和离群集上产生了准确和一致的预测,强调了其在各种数据集上的稳健性和可靠性。此外,HSVR模型在预测精度方面优于其他可用模型。这些发现突出了计算建模作为一种快速、成本效益高、道德合理的传统方法替代品的潜力。这一进步对化妆品和制药行业更安全的产品开发做出了重大贡献。

Modeling skin sensitization: hierarchical support vector regression−based prediction of lysine depletion in DPRA
Skin sensitization is a critical endpoint in toxicology, especially in the context of drug discovery and development process for topical and transdermal treatments. Accurate evaluation of skin sensitization potential is essential to ensure the safety and efficacy of new compounds before their incorporation into commercial products. In this study, a quantitative structure−activity relationship (QSAR) model employing a hierarchical support vector regression (HSVR) scheme was developed to quantitatively predict the percentage of lysine depletion measured by the Direct Peptide Reactivity Assay (DPRA) that is one of the keys factors used to identify the skin sensitization potential of chemical compounds. The results demonstrated that the HSVR model produced accurate and consistent predictions across the training, test, and outlier sets, underscoring its robustness and reliability across various datasets. Moreover, the HSVR model showed outperformed other available models in terms of predictive accuracy. These findings highlight the potential of computational modeling as a rapid, cost−effective, and ethically sound alternative to traditional methods. This advancement represents a significant contribution to safer product development in the cosmetic and pharmaceutical industries.

期刊介绍: Chemico-Biological Interactions publishes research reports and review articles that examine the molecular, cellular, and/or biochemical basis of toxicologically relevant outcomes. Special emphasis is placed on toxicological mechanisms associated with interactions between chemicals and biological systems. Outcomes may include all traditional endpoints caused by synthetic or naturally occurring chemicals, both in vivo and in vitro. Endpoints of interest include, but are not limited to carcinogenesis, mutagenesis, respiratory toxicology, neurotoxicology, reproductive and developmental toxicology, and immunotoxicology.
