Dual Effects of Indoleamine 2,3-Dioxygenase Inhibitors on the Therapeutic Effects of Cyclophosphamide and Cycloplatam on Ehrlich Ascites Tumor in Mice

Bulletin of Experimental Biology and Medicine Aims and scope

Ethyl pyruvate, an inhibitor of indoleamine 2,3-dioxygenase, slightly suppressed the growth of transplantable Ehrlich tumor in mice and signifi cantly potentiated the therapeutic effect of cyclophosphamide. Another inhibitor amidoxime produced a similar effect. However, both ethyl pyruvate and amidoxime signifi cantly reduced the effect of cycloplatam therapy. The observed changes can be stipulated by different effects of cyclophosphamide and cycloplatam on the subpopulations of lymphoid cells taking part in the formation of antitumor immunity and resistance to tumors.
