we now describe the actions of the microtubule disrupter , colchicine , on primary cultures of bovine adrenal chromaffin cells and compare these with corresponding actions of beta-lumicolchicine . beta-lumicolchicine is a structural isomer of colchicine which neither binds microtubular protein ( tubulin ) nor interferes with microtubule assembly .
