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.
本发明涉及一种新的与spergualin相关的化合物及其生产方法。这种具有高抗肿瘤活性的新化合物由一般公式##STR1##表示,其中R.sub.1代表氢原子、羟基或具有1至10个碳原子的脂肪酰氧基,R.sub.2代表氨基酸残基(除了α-羟基甘氨酸残基)由α-或ω-氨基和α-羧基中分别去除一个氢原子和羟基得到,该氨基酸残基与相邻的羰基和氨基形成酸酰胺键,m为4至6的整数。
