Abstract

A new biological response modifier, L-(adamant-2-yl)glycyl-L-alanyl-D-isoglutamine hydrochloride (AdTP), recently synthesized and characterized for antitumor, antiviral and immunomodulating properties was studied in comparison to the peptidoglycan monomer (PGM) isolated from Brevibacterium divaricatum to test the effects of their use concomitant to that of anticancer cytotoxic drugs such as cyclophosphamide, 5-fluorouracil (5-FU), cisplatin and 4-(3,3-dimethyl-1-triazeno)-5-carboxamide (dacarbazine). The experiments, performed using both Lewis lung carcinoma and MCa mammary carcinoma of CBA mouse, indicated that: a) the cytotoxic drugs, used at the maximum tolerated doses, caused different degrees of reduction of the tumors; b) the same drugs reduced lung metastases with greater efficacy when treatments were applied at the early stages of metastasis formation; c) AdTP, similarly to PGM confirmed its ability to increase some immunological parameters of lymphocytes obtained from the spleens of the treated mice; d) AdTP increased the effects of 5-FU on lung metastases but failed to show any increase of life expectancy with any treatment performed. These data indicate that AdTP, although increasing some functional responses of lymphocytes in vitro, does not improve the therapeutic activity of cyclophosphamide, cisplatin, 5-FU and dacarbazine in the experimental models presently used.
