Indirubin and its analogue, indirubin-5-sulphonic acid, have shown potent ability to inhibit cyclin-dependent-kinases (CDKs). Using the crystal structure of CDK2 complexed with indirubin-5- sulphonate as the template, models of CDK4 complexed with indirubin and its analogue were built by homology modeling and molecular docking. The structure comparisons of CDK4 with indirubin and its analogue could explain different inhibition ability. Moreover, the different activity of indirubin-5-sulphonic acid complexed with CDK2 and CDK4 was also illustrated. The model structure provided the basis for designing more potent anticancer drug.
