 ### Case Study 2 (a): Antiviral Drugs Repurposing for SARS-CoV2 3CLPro, using One Line.
-  Given a new target sequence (e.g. SARS-CoV2 3CL Protease), retrieve a list of repurposing drugs from a curated drug library of 81 antiviral drugs. The Binding Score is the Kd values. Results aggregated from five pretrained model on BindingDB dataset! (Caution: this currently is for educational purposes. The pretrained DTI models only cover a small dataset and thus cannot generalize to every new unseen protein. For best use case, train your own model with customized data.)
