Deep learning enables discovery of highly potent anti-osteoporosis natural products. Eur J Med Chem. 2020 Oct 31;:112982 Authors: Liu Z, Huang D, Zheng S, Song Y, Liu B, Sun J, Niu Z, Gu Q, Xu J, Xie L Abstract A pre-trained self-attentive message passing neural network (P-SAMPNN) model was developed based on our anti-osteoclastogenesis dataset for virtual screening purpose. Validation processes proved that P-SAMPNN model was significantly superior to the other base line models. A commercially available natural product library was virtually screened by the P-SAMPNN model and resulted in confirmed 5 hits from 10 selected virtual hits. Among the confirmed hits, compounds AP-123/40765213 and AE-562/43462182 are the nanomolar inhibitors against osteoclastogenesis with a new scaffold. Further studies indicate that AP-123/40765213 and AE-562/43462182 significantly suppress the mRNA expression of RANK and downregulate the expressions of osteoclasts-related genes Ctsk, Nfatc1, and Tracp. Our work demonstrated that P-SAMPNN method can guide phenotype-based drug discovery. PMID: 33158578 [PubMed - as supplied by publisher]
