title: Activity of 6-methyl-8-substituted ergolines against the 7,12-dimethylbenz(a)anthracene-induced mammary carcinoma.
abstract: The ability of a series of 8-beta-carboxamido ergolines, 8-formamido ergolines, and 8-methyl ergolines to cause regressions of established dimethylbenz[a]anthracene-induced mammary carcinomas was compared to some ergot alkaloids. Although most of the ergoline derivatives depressed serum prolactin concentrations in rats, only a few had pronounced effects against the dimethylbenz[a]anthracene-induced mammary carcinoma in rats. Some derivatives from each of the three groups of substituted ergolines gave comparable activities against the dimethylbenz[a]anthracene-induced mammary carcinoma.
