Abstract
1A-Higher aliphatic acyl derivatives of mitomycin C have been found to have superior anti-tumor activity and lipid-solubility as compared with known 1a-acyl derivatives of mitomycin C. Also, the new derivatives exhibit far lower toxicity than mitomycin C. These derivatives are represented by the following formula: ##STR1## wherein R is an aliphatic hydrocarbon group having 9-29 carbon atoms or a group wherein a hydrogen atom of the aliphatic hydrocarbon group is substituted by a hydroxy group.
