Abstract :

Kinesins constitute a superfamily of microtubule-based motor proteins with important cellular functions ranging from intracellular transport to cell division. Some kinesin family members function during the mitotic phase of the eukaryotic cell cycle and are crucial for the successful progression of cell division. MKLP-2 (also known as Kif20A, RabK6, RB6K, Rab6KIFL, Rabkinesin6) a member of the kinesin-6 family plays an essential role during cytokinesis and is overexpressed in various cancers such as pancreatic cancer, bladder cancer, breast cancer, small-cell lung cancer, hepatocarcinogenesis, melanoma and gastric cancer. Furthermore, MKLP-2 is weakly detectable or absent in the normal spleen, lymph nodes, pancreas, lung, brain, liver, kidney and skeletal muscle. MKLP-2 is involved in the relocation of chromosome passenger complex CPC (which consists of Aurora B, INCENP, surviving and borealin) to the spindle midzone. Down regulation of MKLP2 inhibits the growth of gastric and pancreatic cancer cells. We recently identified one compound (named paprotrain) as the first known inhibitor of MKLP-2. Paprotrain does not inhibit other members of the kinesin superfamily involved in mitosis. The synthesis, the structure-activity relationships and the biological activities will be discussed.
