Thursday, May 10, 2018, Baltimore, MD - Insilico Medicine, a Baltimore-based next-generation artificial intelligence company specializing in the application of deep learning for target identification, drug discovery and aging research announces the publication of a new research paper in Molecular Pharmaceutics journal titled "Adversarial Threshold Neural Computer for Molecular De Novo Design". The described Adversarial Threshold Neural Computer (ATNC) model based on the combination of Generative Adversarial Networks (GANs) with Reinforcement Learning (RL) is intended for the design of novel small organic molecules with the desired set of pharmacological properties.
"This is a proof of concept scratching the surface of what we have in house. Stay tuned for the cool experimental validation results to be announced this Summer. I hope that part of this work integrated into our pipeline will help make the world a better and healthier place and help make perfect molecules for specific targets and multiple targets that will have a much higher chance of becoming great drugs", said Evgeny Putin, the deep learning lead at Insilico Medicine.
The architecture of GANs was initially proposed by Ian Goodfellow in 2015, and since the inception, the GAN-based models have achieved the unprecedented accuracy in image, video and text generation. The fundamental principle of GANs is adversarial training based on the competition between the Generative and Discriminative networks that leads to joint evolution and highly accurate results with the desired properties. Insilico Medicine scientists pioneered the application of GANs and their conjunction with RL for drug discovery process and published the proof of concept.
"The GAN-RL architecture proposed by Putin in this paper demonstrated the ability to generate a substantial percentage of valid and unique molecular structures. This study is a proof of concept using string representations of molecular structure and internally we are using multiple integrated generators with reinforcement learning and the proprietary representation of molecular structure, which allows us to synthesize the exact molecules and link chemistry and biology", said Alex Zhavoronkov, the founder and CEO of Insilico Medicine.
Insilico Medicine is regularly publishing research papers in peer-reviewed journals. The company was first who applied deep generative adversarial networks (GANs) to the generation of new molecular structures with specified parameters and published seminal proof of concept papers in the field. The paper published in Molecular Pharmaceutics in 2016 demonstrated the proof of concept of the application of deep neural networks for predicting the therapeutic class of the molecule using the transcriptional response data, received the American Chemical Society Editors' Choice Award. A recent paper published in November 2017 described the application of the next-generation AI and blockchain technologies to return the control over personal data back to the individual. One of the latest papers published in the Journals of Gerontology demonstrated the application of the deep neural networks to assessing the biological age of the patients.
