Abstract
The antineoplastic and antimetastatic activities of coumarin were evaluated in transplanted prostate tumours of the rat. The growth of Noble Nb-R prostate tumours was strongly inhibited by coumarin (40 mg/kg; administered three times per week), whereas the hormonally more sensitive Dunning R3327-G rat prostate carcinoma did not respond. Coumarin was also shown to possess antimetastatic activity in a Dunning R3327-MatLu tumour model. The number of lung metastases was reduced significantly by 40%-50% following the administration of coumarin (40 mg daily). Preliminary data from experiments with rats bearing DMBA-induced mammary carcinomas showed that these tumours are as sensitive to coumarin as Noble-R-prostate tumours.
