hERG K+通道的阻断与致死性心律失常密切相关。该通道臭名昭著的配体混杂性使hERG成为药物开发过程早期阶段考虑的最重要的抗靶标之一。在这里,我们报告了一个创新的和免费访问的网络服务器的发展,早期识别推定的hERG阻滞剂和非阻滞剂的化学图书馆。我们收集了最大的公开可用的5,984种化合物的hERG数据集。我们成功地开发了强大的外部预测二进制(CCR ≥ 0.8)和多类模型(准确度≥ 0.7)。这些模型可以作为一个网络服务免费提供给公众在http://labmol.farma-cia.ufg.br/predherg/。用户可以得到以下三种结果:二元模型预测、多类模型预测和原子贡献概率图。随着新信息的出现,Pred-hERG将不断更新和升级。
The blockage of the hERG K+ channels is closely associated with lethal cardiac arrhythmia. The notorious ligand promiscuity of this channel earmarked hERG as one of the most important antitargets to be considered in early stages of drug development process. Herein we report on the development of an innovative and freely accessible web server for early identification of putative hERG blockers and non-blockers in chemical libraries. We have collected the largest publicly available curated hERG dataset of 5,984 compounds. We succeed in developing robust and externally predictive binary (CCR ≈0.8) and multiclass models (accuracy ≈0.7). These models are available as a web-service freely available for public at http://labmol.farma-cia.ufg.br/predherg/. Three following outcomes are available for the users: prediction by binary model, prediction by multi-class model, and the probability maps of atomic contribution. The Pred-hERG will be continuously updated and upgraded as new information became available.
