Absorption, distribution, metabolism, and excretion (ADME) studies are critical for drug discovery. Conventionally, these tasks, together with other chemical property predictions, rely on domain-specific feature descriptors, or fingerprints. Following the recent success of neural networks, Accutar developed Chemi-Net, a completely data-driven, domain knowledge-free, deep learning method for ADME property prediction. To compare the relative performance of Chemi-Net with Cubist, one of the popular machine learning programs used by Amgen, a large-scale ADME property prediction study was performed on-site at Amgen. The results showed that our deep neural network method improved current methods by a large margin. Accutar foresee that the significantly increased accuracy of ADME prediction seen with Chemi-Net over Cubist will greatly accelerate drug discovery.

Jan 10, 2018: Accutar’s side chain flexible docking platform assisted discovery of bisubstrate inhibitors of Nicotinamide N-Methyltransferase (NNMT)

A bisubstrate NNMT inhibitor was developed aided by accutar platform recently. The binding pose of designed inhibitor with hNNMT was predicted by Accutar’s side chain flexible docking method. The docking result was further validated by crystallization experiment.

Jul 26, 2017: Publication of drug binding pocket side chain prediction by deep neural network

Using a deep neural network architecture without physics-based assumptions, Accutar have demonstrated that side chain conformation prediction accuracy can be improved by more than 25%, especially for aromatic residues compared with current standard methods.
