Synthesis and structure-activity relationships of benzophenone-bearing diketopiperazine-type anti-microtubule agents
KPU-105 (4), a potent anti-microtubule agent that contains a benzophenone was derived from the diketopiperazine-type vascular disrupting agent (VDA) plinabulin 3, which displays colchicine-like tubulin depolymerization activity. To develop derivatives wit
