Synthetic studies on mitotic kinesin Eg5 inhibitors: Synthesis and structure-activity relationships of novel 2,4,5-substituted-1,3,4-thiadiazoline derivatives

The 2,4,5-substituted-1,3,4-thiadiazoline derivative 1a has been identified as a new class of mitotic kinesin Eg5 inhibitor. With the aim of enhancement of the mitotic phase accumulation activity, structure optimization of side chains at the 2-, 4-, and 5
