Title:
DISULFIDE COMPOUNDS AND ANTINEOPLASTIC AGENTS
Document Type and Number:
WIPO Patent Application WO/1986/004898
Kind Code:
A1
Abstract:
Mitomycin derivatives represented by general formula (I), wherein X represents X1 or X2, X1 represents an alkyl group, a cycloalkyl group (optionally substituted), a pyridyl group, an unsubstituted or substituted phenyl group, a residue of an amino acid having a thiol group or a dipeptide or tripeptide residue containing the amino acid excluding the thiol group, X2 represents a group represented by formula (II), (wherein A1 represents -(CH2)m- (wherein m represents an integer of 3 to 12) or -(CH2CH2O)n-CH2CH2- (wherein n represents an integer of 1 to 5), Y, Z, R1, and R2 are the same as defined with (I), provided that A represents -(CH2)$(1,3)$- (wherein$(1,4)$represents an integer of 3 to 8) when X is X1 and A represents A1 when X ix X2, Y and Z each represents H or methyl, and one of R1 and R2 represents a carbamoyloxymethyl group and the other represents H when X is X1, and one of them represents a carbamoyloxymethyl group and the other represents H, or both are bound to each other to form an exo-methylene group (=CH2) when X is X2. These compounds are superior to known mitomycin derivatives having two methylene units between a nitrogen atom at 7-position and a SS grouping in at least one of CI value (chemotherapeutic index), reduction of side effects, and solubility in water.
