Virtual screening is receiving renewed attention in drug discovery, but progress is hampered by challenges on two fronts: handling the ever-increasing sizes of libraries of drug-like compounds and separating true positives from false positives. Here, we developed a machine learning-enabled pipeline for large-scale virtual screening that promises breakthroughs on both fronts. By clustering compounds according to molecular properties and limited docking against a drug target, the full library was trimmed by 10-fold; the remaining compounds were then screened individually by docking; and finally, a dense neural network was trained to classify the hits into true and false positives. As illustration, we screened for inhibitors against RPN11, the deubiquitinase subunit of the proteasome, and a drug target for breast cancer.

用于大规模虚拟药物筛选的机器学习管道

虚拟筛选在药物发现中得到了新的关注，但进展受到两个方面的挑战的阻碍：处理不断增加的类药物化合物库以及区分真阳性和假阳性。在这里，我们开发了一种支持机器学习的管道，用于大规模虚拟筛选，有望在两个方面取得突破。通过根据分子特性对化合物进行聚类并限制与药物靶点的对接，整个库被修剪了 10 倍；然后通过对接单独筛选剩余的化合物；最后，训练一个密集的神经网络，将命中分类为真假阳性。作为说明，我们筛选了针对 RPN11（蛋白酶体的去泛素酶亚基）和乳腺癌药物靶点的抑制剂。
