摘要:
The invention relates to Spergualin-related compounds of the formula: ##STR1## (wherein R.sub.1 is a lower alkylene group which may be substituted by a hydroxymethyl group; X is a hydrogen atom or a halogen atom; m and n are each 0 or an integer of 1 to 5) and salts thereof and a process for producing the same.
摘要:
This invention relates to a novel spergualin-related compound and a process for the production thereof. The novel compound, which has a high antitumor activity, is represented by the general formula ##STR1## wherein R.sub.1 represents a hydrogen atom, hydroxyl group, or an aliphatic acyloxy group having 1 to 10 carbon atoms, R.sub.2 represents an amino acid residue (except for the residue of .alpha.-hydroxyglycine) formed by removing one hydrogen atom and hydroxyl group from respectively the .alpha.- or .omega.-amino group and the .alpha.-carboxyl group of an .alpha.- or .omega.-amino acid, said amino acid residue forming acid amide linkages with the adjacent carbonyl group and amino group, and m is an integer of 4 to 6.
