| Outline of Final Research Achievements |
The chemical space subject to pharmaceutical developments consists of 10~60 pharmaceutical candidates. Our challenge is to discover new compounds in the huge space that exhibit desired properties on various pharmacological activities, required to be a drug. The aim of this study is to create a new molecular design method by the integration of Bayesian and machine learning methods. Our approach is as follows: (a) we develop forward prediction models based on experimental data that predict the properties of a compound with the chemical structure, (ii) the backward prediction is derived by inverting the forward model according to the Bayes formula, and (iii) the backward model is used to generate new compounds with the chemical structures likely to achieve desired pharmacological activities. Under industry-academia partnerships, we are putting into practice the developed method in the area of resin and pigment chemistry in addition to pharmaceutical developments.
