Abstract:
Fifteen KSP inhibitors were docked into the receptor and the binding mode was analyzed for the first time. It was considered that in addition to the main binding pocket all the inhibitors merged in, there exists a cooperative minor binding pocket, which could be explored for significantly increased binding affinity. In addition, a good linear relationship between the biological activities and the lowest binding free energies has also been found. This may help in predicting the binding affinity of newly designed KSP inhibitors.
