    • PURPOSE:To provide a carcinostatic agent containing a microorganism-originated protease as an active component, exhibiting remarkable carcinostatic activity against various tumors, keeping the carcinostatic effect for a long period at the local point of the cancer and having low cytotoxicity to normal cell. CONSTITUTION:A protease originated from microorganism (e.g. neutral protease originated from Serratia marcescens) is used as an active component. The behavior of a polymeric carcinostatic agent applied locally to the tumor tissue is completely different from that of low-molecular carcinostatic agent. The polymeric substance is retained for a long period at the local tumor without being recovered and secreted either hematogenically nor lymphogenically. Accordingly, when the microorganism-originated polymeric protease is applied to the local position of cancer, an excellent carcinostatic effect can be attained and the drug action is continued for a long period. Furthermore, it has been found that the cytotocity against normal cell is considerably lower than the cytotoxity against cancer cell.

    • PURPOSE:A carcinostatic agent containing a neocarzinostatin derivative having low toxicity, being accumulated specifically in lymphocyte. CONSTITUTION:A carcinostatic agent containing a compound shown by the formula (ring N is neocarzinostatin residue; R1+R2 is residue of styrene-maleic acid copolymer having 2,500-80,000mol.wt) as an active ingredient. Administration in tissue of affected part such as primary site of cancer, site from which cancer is extracted after operation, etc., intracutaneous, hypodermic, intramuscular, intravenous, and oral medication, etc., application to the affected part, and administration of external use such as suppository may be used as the administration. A dose is 0.1-10mg/kg/time/day, preferably once-twice per week or daily administration. The compound shown by the formula as the active ingredient is obtained by reacting neocarzinostatin with a styrene-maleic acid copolymer containing at least one maleic anhydride residue in the molecule in neutrality or in weak basicity at 0-40 deg.C.
