[Comparative study of anti-tumor activity of the monoglucosides protopanaxadiol and betulafolientriol].

Abstract
Antitumor and cytotoxic activity of monoglucosides such as 3-0-panaxadiol (1), 12-0-panaxadiol (2) and 20-0-panaxadiol (3) and 3-0-betulafolientriol (4), 12-0-betulafolientriol (5) and 20-0-betulafolientriol (6) was studied. It was found that in concentrations of 10 to 50 micrograms/ml the above monosides induced marked impairment of the selective permeability of the tumor cells and the inhibition of the labeled precursor inclusion into the macromolecule biosynthesis. Administration of the monosides in a single dose of 100 mg/kg 24 hours after the inoculation of the Ehrlich tumor cells resulted in prolongation of the mean life-span of the mice by 144 per cent (1), 153 per cent (2), 144 per cent (3), 125 per cent (4), 133 per cent (5) and 178 per cent (6). A significant reduction of the tumor mass was observed at the early stages of the tumor development and later the tumor progress intensively resumed. The tests for the effect of the monoside-activated macrophages on the growth of the tumor cells showed that production of the growth factors by the macrophages was stable and had a negative action on the efficacy of the chemotherapy with the monoglucosides.
