Antitumour activity of chlorimidazine on transplantable mouse tumour systems.

The antitumour activity of the newly synthesized compound, chlorimidazine (1-chlorethyl-2-chlormethyl-2-imidazoline hydrochloride), has been investigated on mouse tumour systems including L 1210 and P 388 leukaemias and Lewis lung carcinoma. It has been found that optimum treatment schedules resulted in 153% T/C in mice with L 1210 leukaemia, 159% T/C in mice bearing P 388 leukaemia and 68% TWI for Lewis lung carcinoma. Due to the results obtained the compound acts as a novel potential antitumour agent that warrants further evaluation.
