Drug-induced phospholipidosis (PLD) involves the accumulation of phospholipids in cells of multiple tissues, particularly within lysosomes, and it is associated with prolonged exposure to druglike compounds, predominantly cationic amphiphilic drugs (CADs). PLD affects a significant portion of drugs currently in development and has recently been proven to be responsible for confounding antiviral data during drug repurposing for SARS-CoV-2. In these scenarios, it has become crucial to identify potential safe drug candidates in advance and distinguish them from those that may lead to false in vitro antiviral activity. In this work, we developed a series of machine learning classifiers with the aim of predicting the PLD-inducing potential of drug candidates. The models were built on a high-quality chemical collection comprising curated small molecules extracted from ChEMBL v30. The most effective model, obtained using the balanced random forest algorithm, achieved high performance, including an AUC value computed in validation as high as 0.90. The model was made freely available through a user-friendly web platform named AMALPHI (https://www.ba.ic.cnr.it/softwareic/amalphiportal/), which can represent a valuable tool for medicinal chemists interested in conducting an early evaluation of PLD inducer potential.
药物性磷脂沉积症(PLD)涉及多种组织细胞中磷脂的积累,尤其是在溶酶体内,并且与长期接触类药物化合物有关,主要是阳离子两亲性药物(CADs)。PLD影响了目前正在研发的很大一部分药物,最近已被证明是在将药物重新用于治疗SARS-CoV-2期间混淆抗病毒数据的原因。在这些情况下,提前识别潜在的安全药物候选物并将它们与那些可能导致体外抗病毒活性假象的药物区分开来变得至关重要。在这项工作中,我们开发了一系列机器学习分类器,旨在预测药物候选物诱导PLD的潜力。这些模型基于一个高质量的化学数据集构建,该数据集包含从ChEMBL v30中提取的经过整理的小分子。使用平衡随机森林算法获得的最有效模型具有高性能,包括在验证中计算的AUC值高达0.90。该模型通过一个名为AMALPHI(https://www.ba.ic.cnr.it/softwareic/amalphiportal/)的用户友好型网络平台免费提供,这对于有兴趣对PLD诱导剂潜力进行早期评估的药物化学家来说可能是一个有价值的工具。
