Abstract
Abstract Benzene-ring substituted (2-methylhydrazino)-methyl-benzene compounds and intermediates therefore are described. The former compounds are useful as cytostatic agents and, particularly, inhibit the growth of transplantable tumors in both mice and rats. Thus, they are active, for example, against Walker tumors, Ehrlich carcinoma and Ehrlich ascites carcinoma.
