Given a compound, can we predict which anatomical therapeutic chemical (ATC) class/classes it belongs to? It is a challenging problem since the information thus obtained can be used to deduce its possible active ingredients, as well as its therapeutic, pharmacological and chemical properties. And hence the pace of drug development could be substantially expedited. But this problem is by no means an easy one. Particularly, some drugs or compounds may belong to two or more ATC classes.
To address it, a multi-label classifier, called iATC-mISF, was developed by incorporating the information of chemical–chemical interaction, the information of the structural similarity, and the information of the fingerprintal similarity. Rigorous cross-validations showed that the proposed predictor achieved remarkably higher prediction quality than its cohorts for the same purpose, particularly in the absolute true rate, the most important and harsh metrics for the multi-label systems.
The web-server for iATC-mISF is accessible at http://www.jci-bioinfo.cn/iATC-mISF. Furthermore, to maximize the convenience for most experimental scientists, a step-by-step guide was provided, by which users can easily get their desired results without needing to go through the complicated mathematical equations. Their inclusion in this article is just for the integrity of the new method and stimulating more powerful methods to deal with various multi-label systems in biology.

给定一个化合物,我们能否预测它属于哪个解剖治疗化学(ATC)类别/类别?这是一个具有挑战性的问题,因为由此获得的信息可用于推断其可能的活性成分,以及其治疗、药理学和化学性质。因此,药物开发的速度可以大大加快。但这个问题绝非易事。特别是,一些药物或化合物可能属于两个或更多的 ATC 类别。
为了解决这个问题,我们开发了一种称为 iATC-mISF 的多标签分类器,该分类器结合了化学-化学相互作用的信息、结构相似性的信息和指纹相似性的信息。严格的交叉验证表明,与同类方法相比,所提出的预测器在相同目的下实现了显著更高的预测质量,特别是在绝对真实率方面,这是多标签系统最重要和最严格的指标。
iATC-mISF 的网络服务器可在 http://www.jci-bioinfo.cn/iATC-mISF 上访问。此外,为了最大限度地为大多数实验科学家提供便利,我们提供了一个逐步指南,用户无需经历复杂的数学方程即可轻松获得所需的结果。我们在本文中包含它们只是为了新方法的完整性,并激发更强大的方法来处理生物学中的各种多标签系统。
