Outline of Final Research Achievements

It was very difficult in the past to screen inhibitors of JARID1B, one of epigenome regulatory factor. We have made it possible using our in silico screening technologies with large-scale computer. In silico screening has been already performed to pick up the candidate compounds from five million drug like compounds. Then, we selected first lead compounds from the picked up candidate compounds with chemical assay. We have investigated the in vitro anti-cancer effects of these lead compounds, and the after, investigated the in vivo anti-cancer effects for the part of them. We succeeded in establishing a pathway to show the synthetic evolution guidelines for lead compounds based on the functional information from these experimental results. According to this procedure, it is possible to design a more efficient drug structure.
