Outline of Final Research Achievements |
We performed docking-based virtual screening for acetohydroxy acid (AHAS) synthase with about 1.06 million three-dimensional molecules containing isomers made from about 600,000 chemicals representatively selected from Namki Shoji's compound library (about 7.79 million). AutoDock-Vina and myPresto were used for calculation. 174 compounds were selected by consensus analysis and final visual confirmation. The ability of these compounds to inhibit AHAS activity was assayed and compared with the commercially available herbicide bensulfuron-methyl. We found 13 compounds showing inhibition greater than 90% against bensulfuron-methyl. The compound with the best result showed 131% inhibition. Although it is necessary to investigate in more detail such as obtaining IC50 in the future, it was shown that this method can efficiently search for inhibitors.
