  The co-crystal structure of Compound 6b with tubulin was prepared and solved for indicating the binding mode and for further optimization. Based on the co-crystal structures of tubulin with plinabulin and Compound 6b, a total of 27 novel A/B/C-rings plinabulin derivatives were designed and synthesized. Their biological activities were evaluated against human lung cancer NCI-H460 cell line. The optimum

  KPU-105 (4), a potent anti-microtubule agent that contains a benzophenone was derived from the dike-topiperazine-type vascular disrupting agent (VDA) plinabulin 3, which displays colchicine-like tubulin depolymerization activity. To develop derivatives with more potent anti-microtubule and cytotoxic activities, we further modified the benzophenone moiety of 4. Accordingly, we obtained a 4-fluorobenzophenone derivative 16j that inhibited tumor cell growth in vitro with a subnanomolar IC50 value against HT-29 cells (IC50 = 0.5 nM). Next, the effect of 16j on mitotic spindles was evaluated in HeLa cells. Treatment with 3 nM of 16j partially disrupted the interphase microtubule network. By contrast, treatment with the same concentration of CA-4 barely affected the microtubule network, indicating that 16j exhibited more potent anti-mitotic effects than did CA-4.
