Anti-angiogenic agents were be clinically useful for the therapy of solid tumors, as the growth and proliferation of tumors require neovascularization. Previous reports have been made on the antitumor effect of TNP-470, an angiogenic inhibitor, on medulloblastomas implanted subcutaneously into nude mice. The present study was undertaken for the purpose of investigating possible antitumor effects on two model subcutaneous and intracranial tumors transplanted into rats. 9-L gliosarcomas were transplanted into the left femoral region subcutaneously and the left frontal region of Fisher 344 female rats, and the TNP-470 was then administered subcutaneously. The rats were divided into two treatment groups and a control group. TNP-470 resulted in dose-dependent inhibition of 9-L gliosarcoma growth and also prolonged survival in treatment groups. Therefore TNP-470 was considered to be effective for the treatment of malignant brain tumors, although it caused dose-dependent decreases in body weight.
