Abstract: New complex salts of hematoporphyrin and of its derivatives have the general Formula 1 (FIG. 1). The method of preparation of new complex salts of Formula 1 consists of reacting, with a basic amino acid, hematoporphyrin derivatives of general Formula 4 (FIG. 4). The new complex salts are used as a therapeutic agent for detection and treatment of neoplasms.
