Abstract

BACKGROUND: AG60 is a complex of acriflavine and guanosine. Our previous study revealed that AG60 had not only in vitro antitumor activities in several human cancer cell lines, but also strong antitumor effects in animal experiments using p388 or S180 cells-implanted mice.
METHODS
Antitumor effects of AG60 were compared with those of Adriamycin, acriflavine, guanosine or control group. Body weight, tumor weight change, and survival time were measured in Ehrlich carcinoma cells implanted ICR mice.
RESULTS
Body weights in AG60, acriflavine, or Adriamycin treated groups were significantly lower than those in control group during 30 day observation period(p<0.05). The percent tumor growth inhibition of AG60, Adriamycin, acriflavine, or guanosine two weeks after last treatment was respectively 86% (T/C%=14), 83% (T/C%=17), 68%(T/C%=32), 41% (T/C%=59). According to above data, tumor growth inhibition in AG60 treated group was significantly stronger than that in control, acriflavine or guanosine treated group(p<0.01), but there was no significant difference between AG60 and Adriamycin treated group. Mean survival time in control, AG60, Adriamycin, acriflavine, or guanosine treated group was respectively 33+/-3.9 days, 68+/-4.2 days, 54+/-5.8 days, 36+/-3.8 days, 50+/-8.1 days.
CONCLUSIONS
The anti-tumor effect of AG60 against Ehrlich tumor was significantly stronger than that of control, acriflavine or guanosine, and comparable with Adriamycin. Mean survival time in AG60 treated group was significantly longer than that in control, acrifavine, guanosine or Adriamysin treated group.
