摘要:
A compound represented by the formula: wherein R is a hydrogen atom or a lower alkyl group, X is a hydroxymethyl group and Y is a cyano group, and when R is a lower alkyl group, X and Y may combine to form -CH 2 -O-, and salts thereof, process for preparing the same, and an anti-tumor composition containing the same, which is improved in stability in comparison with a starting compound DC-52.
摘要:
Novel DC-89 compounds represented by the general formula: wherein X represents a single bond or -CH₂-; and when X represents a single bond, Y represents -CH₂Br or -CH₂Cl and when X represents -CH₂-, Y represents Br, are obtained by the present invention. The compounds have antibacterial and anti-tumor activity.
