Abstract

Bropirimine is an oral immunostimulant found to have efficacy in human transitional cell carcinoma in situ following the initial discovery of its antitumor activity against the murine bladder cancer MBT-2. To determine if bropirimine might have activity in prostate cancer, it was tested against two rodent prostate cancer cell lines in vivo.Tumors resulted from subcutaneous injection of PAIII and Dunning MAT-LyLu rodent prostate cancer cells. Bropirimine was given at 250 mg/kg orally on different schedules, and tumor volume and survival were recorded.In the PAIII model, bropirimine prevented growth when given the day of tumor injection, and 95% of advanced tumors regressed completely when start of therapy was delayed. Bropirimine also caused growth inhibition and prolongation of survival in the MAT-LyLu model.Bropirimine immunotherapy is very effective in vivo against the PAIII cell line, and it has significant growth inhibition against the Dunning MAT-LyLu cell line.
