Estimation of antitumor activity of compound T1097 - NOS inhibitor and glycolysis inhibitor - on experimental Erlich carcinoma in vivo

Abstract The antitumor potential of a new original compound T1097 to realize a complex antineoblastic effect - NOS-inhibiting anti-angiogenic and HK2-inhibiting hypoxia-oriented cytotoxic - was investigated on the model of transplantable Ehrlich carcinoma in vivo. During the entire observation period, T1097 showed pronounced dose-dependent antitumor properties: statistically significant inhibitory effect of T1097 on the growth of tumor nodes exceeded the effect of original compound - HK2-inhibitor 3-bromopyruvate in an equimolar dose. The maximum antineoblastic effect (61%) of T1097 was obtained with its subchronic parenteral administration at a dose of 17 mg/kg and was not accompanied by the development of tumor resistance. Our findings confirm the prospects of this direction in the search for new drugs.
