Effect of several d-morphinans on ascites tumors in mice.
Dextromethorphan and its analogues (DM 16, DM 34, DM 72, DM 75 and DM 96) were examined for their effect on Ehrlich ascites carcinoma or ascites sarcoma-180 in female mice of the ddY strain. The suspension of Ehrlich carcinoma cells or sarcoma-180 cells was prepared from mice at 10 days after i.p. inoculation of the cells, using Hanks' balanced salt solution, and the cell suspension was inoculated i.p. into mice (2 X 10(6) viable cells/mouse). The chemicals dissolved in physiological saline containing 5% HCO-60 were then injected i.p. into the mice once daily for 5 successive days (5-40 mg/kg/day). In addition, mice given the tumor cells were treated with the saline containing 5% HCO-60 alone for 5 days (untreated mice). In groups of mice bearing Ehrlich ascites carcinoma or ascites sarcoma-180, the mean survival time of mice treated with 20-40 mg/kg/day of DM 96 was more than twice that of the corresponding untreated mice. The mean survival time of mice treated with 20 mg/kg/day of DM 96 was also longer than that of mice treated with 40 mg/kg/day of the other chemicals, irrespective of the ascites tumors. Concerning these survival times, the LD50 (i.p.) of DM 96 in mice differed slightly from that of other chemicals (88 mg/kg and 77-106 mg/kg). These results indicate that DM 96 is more active than the other chemicals against the ascites tumors in mice.

Effect of the centrally acting antitussives on ascites tumor cells.
Dextromethorphan, dimemorfan, dihydrocodeine and oxymethebanol, centrally acting antitussives, were examined for their effect on Ehrlich carcinoma cells and sarcoma-180 cells in vitro or in vivo. The tumor cells were suspended in Hanks balanced salt solution (pH 7.4) supplemented with 2% bovine albumin, and they were incubated with and without 1 mM drugs at 37 degrees C for 120 min. The incubation of the tumor cells with dextromethorphan or dimemorfan resulted in a decrease in the proportion of the viable cells (less than 25% after 120 min). However, no significant change was observed in the proportion of the viable tumor cells during the incubation with and without the other drugs (80-83% after 120 min). In addition, mice given the tumor cells i.p. were injected intraperitoneally with drugs (20-80 mg/kg/day) once daily for 5 successive days, and their survival time was observed. There was a slight difference in the survival time between mice treated with and without dextromethorphan or dimemorfan. However, a significant difference was found in the survival time between mice treated with and without dextromethorphan when mice given Ehrlich carcinoma cells were injected with the drug (40 mg/kg/time) twice a day for 5 days (about 18 days and 29 days). These results indicate that dextromethorphan and dimemorfan are cytotoxic to the tumor cells in vitro and in vivo.
