    Notes: Summary The chemotherapeutic activity of five cytostatic drugs was investigated experimentally in monotherapy and in two-drug combinations, using Yoshida sarcoma cells implanted into the wall of the glandular stomach of Sprague-Dawley rats. In monotherapy, the antibiotic agent mitomycin C and the nitrosourea methyl-CCNU exhibited the highest cytotoxic activity in this tumor model. In combination therapy, the combination of these two drugs was superior to all the other therapeutic schemes tested. In general, the results demonstrate a marked superiority of combination therapy in comparison with monotherapy.

    Description / Table of Contents: Zusammenfassung Die chemotherapeutische Wirkung von 12 neu entwickelten Nitrosoharnstoffen wurde vergleichend an Yoshida-Sarkom-Asziteszellen experimentell untersucht, die in die Wand des Colon descendens von Sprague-Dawley-Ratten implantiert worden waren. Cyclophosphamid sowie die Nitrosoharnstoffe BCNU, MeCCNU und Chlorozotocin dienten als positive Kontrolle. Unter den untersuchten Nitrosoharnstoffen zeigten 1-(2-Hydroxyethyl)-3-(2-chlorethyl)-3-nitrosoharnstoff (Hydroxyethyl-CNU), Chlorozotocin, 1-(2-Chlorethyl)-1-nitroso-3-(4-morpholino)-harnstoff, 1-(2-Chlorethyl)-1-nitroso-3-(1-piperidino)-harnstoff, 4-[1-(2-Chlorethyl)-1-nitroso]-3-[4-(2,6-dimethylmorpholino)]-harnstoff und 1-(2-Chlorethyl)-1-nitroso-3-(3,4-methylendioxybenzyl)-harnstoff die stärkste Aktivität in diesem Tumormodell. Auf Grund der vorliegenden Ergebnisse ist Morpholino-CNU als die erfolgversprechendste Substanz unter den neu synthetisierten BCNU-Analogen anzusehen.
    Notes: Summary The chemotherapeutic activity of 12 newly synthesized nitrosoureas was compared in tests using Yoshida sarcoma ascites cells implanted into the wall of the descending colon in Sprague-Dawley rats. Cyclophosphamide and the nitrosoureas, BCNU, MeCCNU, and chlorozotocin served as positive controls. Among the nitrosoureas tested, 1-(2-hydroxyethyl)-3-(2-chloroethyl)-3-nitrosourea (hydroxyethyl-CNU), chlorozotocin, 1-(2-chloroethyl)-1-nitroso-3-(4-morpholino) urea, 1-(2-chloroethyl)-1-nitroso-3-(1-piperidino) urea, 4-[1-(2-chloroethyl)-1-nitroso]-3-[4-(2,6-dimethylmorpholino)] urea, and 1-(2-chloroethyl)-1-nitroso-3-(3,4-methylenedioxybenzyl) urea were found to be the most active compounds in this tumor model. Based on the present results, morpholino-CNU is considered the most promising compound among these newly synthesized BCNU analogues.
