摘要: Drug complexes wherein a carboxy (C1-4)alkyldextran polyalcohol, which has been treated under such conditions as to allow the substantially complete formation of the polyalcohol, is bonded to the residue of a medicinal compound such as an antitumor agent via a spacer consisting of one amino acid or a spacer consisting of two to eight amino acids bonded to each other via peptide bonds. The complexes are excellent in the tumor site selectivity and thus can exhibit a high antitumor effect with relieved expression of toxicity.

摘要: A physiologically active protein (including a fused protein comprising the same and a peptide bonded thereto through an amide linkage) is improved in the adaptability to a medicine by modifying the protein through the action of a transglutaminase on the same and an amino group donor having a polyethylene glycol, polysaccharide, polyamino acid or branched saccharide derivative portion without detriment to the inherent physiological activity.
