Effect of 1-(2-chloroethyl)-3-(beta-D-glucopyranosyl)-1-nitrosourea on experimental tumors

A newly synthesized water-soluble nitrosourea derivative, 1-(2-chloroethyl)-3-(beta-D-glucopyranosyl)-1-nitrosourea (GANU; NSC-254157) has marked activities against experimental tumors such as lymphoid leukemia L-1210, ascites sarcoma- 180, ascites hepatoma AH-130, and Walker carcinosarcoma-256. A single intraperitoneal injection of the compound is more effective than successive injections on the L-1210 system. An especially interesting point is that both the single intraperitoneal and single oral administrations 2 days after tumor implantation showed a high effectiveness. In addition, growth of the mammary adenocarcinoma transplanted subcutaneously on the back of mice was also considerably suppressed by successive intraperitoneal injections of the compound.
