Emerging drug resistance and other drawbacks limit tubulin inhibitors' therapeutic applications and developing novel tubulin inhibitors still attracts intensive efforts. We describe the discovery and structure-activity relationship study of a series of benzimidazole-2-urea derivatives as novel β tubulin inhibitors. The representative compound 6o potently suppressed the proliferation of a panel of human cancer cells (NCI-H460, Colo205, K562, A431, HepG2, Hela, MDA-MB-435S) with IC50 values of 0.040, 0.050, 0.006, 0.026, 1.774, 0.452 and 0.052 μM, respectively. Compound 6o obviously inhibited NCI-H460 spindles formation and induced cell cycle arrest at G2/M phase at 0.10 μM. Computational study suggested that 6o interacts with β tubulin in a novel binding mode. Our results suggested that benzimidazole-2-urea derivatives might be promising tubulin inhibitors with novel binding mode for further development.
Bis-ethynyl heterocyclic compositions and method of synthesis

Bis-ethynyl quinoxaline compositions are prepared by the condensation reaction of an aromatic diglyoxyl or dibenzil with an ethynyl-substituted aromatic ortho-diamine. The compositions are useful as polymerizable plasticizers for heterocyclic thermoplastic resins in the fabrication of composites. Polymerizable plasticizers are materials that remain fluid and act as a plasticizer during early stages of fabrication and then polymerize to a rigid resin.

An aromatic bis(o-diamine) is reacted with an aromatic bisbenzil to provide a benzil end-capped quinoxaline oligomer which is then reacted with 4-(3-ethynylphenoxy)orthophenylene diamine to give an ethynyl terminated polyquinoxaline. Because the polyquino
