[A glycolytic marker test for individualizing the selection of chemical compounds for antitumor activity]

Based on literature data on effects of various preparations on the glycolysis in tumor and normal cells, a glycolytic molecular biochemical marker is proposed to screen chemical substances as potential antitumor drugs. A glycolytic specificity was noted in tumor cells which was regarded as a criterion for distinction of tumor cells from normal ones and among various histotypes of tumor cells as well as for the selective sensitivity of tumor cells to a substance. 17 of 38 substances tested were observed to inhibit glycolysis in tumor cells. The testing chemical substances for an antitumor activity with application of the glycolytic marker is recommended. A possibility is discussed of applying the marker for testing potential antitumor drugs, their individualization, and genetic typing.
