The p-[N,N-bis (2-chloroethyl)amino]phenylacetate esters of 3 beta-hydroxy-N-methyl-17 alpha-aza-D-homo-5 alpha-androstan-17-one and 3 beta-hydroxy-17 alpha-aza-D-homo-5 alpha-androstane have been prepared and their antitumor activity evaluated against L1210 leukemia, P388 leukemia, Ehrlich ascites tumor (EAT) and Lewis Lung Carcinoma (LLC). The results are compared with those of the p-[N,N-bis (2-chloroethyl)amino]phenylacetate of 3 beta-hydroxy-17 alpha-aza-D-homo- 5 alpha-androstan-17-one. The above compounds were also tested in vitro against L1210, P 388, EAT and BHX cell cultures. All compounds were found to be active and their structure-activity relationship is discussed.

The protective effects of carbamazepine (CBZ) were studied in mice inoculated with Lewis Lung Carcinoma (3LL), Madison Lung Carcinoma (M109), L5178Y lymphoma, L1210 leukaemia and Candida albicans. There was no significant increase in survival time of mice treated with CBZ. However, CBZ, as well as its metabolite CBZ 10-11 epoxide (CBZ 10-11 EPOX), showed a significant increase in NK-cell activity. CBZ also produced a significant increase of phagocytosis and killing properties of PMNs. There was no significant difference in the stimulation of splenic lymphocyte blastogenesis by different concentrations of phytohaemagglutinina (PHA), observed between the controls and CBZ treated mice. The results demonstrate that the effect of chronic treatment with CBZ on the immune response is a complex phenomenon which remains a challenge for future research.

Understanding the biology and treatment of various cancers (including leukemia) and immunodeficiency disorders is still an ongoing and experimental process. Animal models have been and continue to be important to this process. This review will focus in on work by ourselves and others that have used murine models assessing the effects in vivo of the Friend virus complex (FVC, composed of a spleen focus forming virus and a murine leukemia helper virus) and solid tumors with metastatic potential in order to evaluate new and innovative therapies. These therapies include radiation, hyperthermia, and newly recognized naturally occurring biomolecules termed cytokines. These cytokines include, but are not limited to, the interferons, the tumor necrosis factors, the interleukins, the hematopoietic colony stimulating factors, lactoferrin and E-type prostaglandins. For example, it has been found that lactoferrin, when administered early enough, prolongs the survival of mice injected, but not yet infected, with the FVC. Of even greater potential usefulness is that mice already infected with the FVC can be completely rescued from death by treatment with split low dosage (150 cGy) total body irradiation. Irradiation treatment was associated with restoration of the T helper to T suppressor cell ratio, natural killer cell activity and marrow proliferative responses to the mitogens PHA and con A which were compromised by the FVC. More recent studies in our laboratory have demonstrated the potential of the interleukins and colony stimulating factors to decrease the metastatic potential of the B16 melanoma and the Lewis Lung Carcinoma cell lines. The cytokines can act in greater than additive fashion and combinations of therapies are possible. This review is meant to increase the awareness of these investigative animal models and the new types of combination therapies that can then be used as the basis for future clinical trials evaluating therapeutic efficacy.

Studies were carried out on the combination of Cimetidine (CMTD) with Cytoxan (CTX) in three murine tumors. While the combination significantly potentiated the anticancer effect of CTX in L1210 leukemia, the results with P388 leukemia were not significantly different. The results with Lewis Lung Carcinoma showed a consistent reduction in the number of metastases. However, there was no consistent concomitant prolongation in survival. The host strain, biology of the tumour and the drug used in combination with CMTD might be some of the factors responsible for the varied response.
