Research Abstract

Angiogenic inhibitors are expected as a new anti-cancer drug. It has not been confirmed that angiogenic inhibotors have therapeutic effects on peritoneal carcinomatosis. We examined the effects of one of the angiogenic inhibitors, TNP-470, on peritoneal carcinomatosis in mice.
TNP-470 in aqueous solution form showed a therapeutic effect when given in an early stage of the disease, while did not in advanced stages. The main side effect of the aqueous TNP-470 was accumulation of ascites induced through osmotic effects by emulsifying agent, sometimes generating a lethal toxicity.
TNP-MS,comprizing TNP-470 in the form of microspheres, was shown to be a dosage from preserving the drug activity, and TNP-MS releases the drug in an active from for a prolonged period of time, in the paritoneal cavity in animals. By these characteristics, TNP-MS achieved a therapeutic effect when administered in relatively advanced stages of peritoneal carcinomatosis in mice.
