ABSTRACT:
Disclosed herein are novel benzophenone derivatives represented by formula I, a pharmaceutically acceptable salt thereof, a hydrate thereof or a solvate thereof, a pharmacological composition containing the same, and a use of the composition as therapeutic drugs. The benzophenone derivatives have an inhibition activity of microtubule formation and can be used to treat a normal proliferative state of a malignant tumor by killing the actively proliferating cells.
