Review Manuscript: RL-GANs in Drug Discovery: ECAAE & ATNC

Abstract Draft

Generative Adversarial Networks (GANs), the leading type of neural networks are drastically reducing cost and time consumed in de novo drug discovery. Novel molecular structures toke months of work in the conventional pipeline just a few years ago. Now, GANs can do the same work in hours. GANs operate by generating new drugs to target disease, instead of relying on screening from limited drug databases as previous classifiers have attempted. Two GANs have been published as of October 2018: the Entangled Conditional Adversarial Auto-encoder (ECAAE)1 and the Adversarial Threshold Neural Computer (ATNC)2. Both have shown some of the first generated molecule in vitro validation ever from neural networks. Validation for both has shown good IC50, selectivity, and inhibition potency for their respective hit kinase inhibitors. The targeted kinases from the successful inhibitor validation tests were JK3, SGK1, and Aurora A/B. These kinases show hyper phosphorylation in cancer of at least 8 organs, Parkinson’s disease, ALS, rheumatoid arthritis, psoriasis, and vitiligo.
