In work at Shanghai Curegene Pharmaceutical Co. Ltd., synthesis and optimization of a series of SARS-CoV-2 3CL protease (3CLpro, Mpro) inhibitors led to the identification of compounds [I], [II] and [III] as lead candidates suitable for further evaluation, based on their enzymatic IC50s (14, 12 and 8.6 nM, respectively), cellular EC50s (36, 26 and 52 nM, respectively) and human liver microsome (HLM) stability.
Novartis AG is enlisting the help of Generate:Biomedicines Inc. and its artificial intelligence platform to generate drugs for multiple undisclosed targets. The number of targets and therapeutic areas also weren’t disclosed. Novartis will pick the targets, although the targets Generate has been working on are off limits. Generate will be responsible for creating the lead candidate, at which point Novartis will take over development.
