One hundred cis-diamminedichloroplatinum (II) (CDDP) analogs have been evaluated for antitumor activity in male CDF1 mice subcutaneously (s.c.) implanted with tumor fragments of Colon 26 carcinoma. Among the complexes tested, 2-aminomethyl-pyrrolidine (1, 1-cyclobutanedicarboxylato) platinum (II) (DWA 2114) had the best antitumor effect. The mice intraperitoneally (i.p.) injected with DWA 2114 at a dose of 40 mg/kg/day on days 4, 6 and 8 after inoculation showed a 97% growth inhibitory ratio (GIR) on day 14 compared to the non-treated control mice. We evaluated the inhibitory effects of DWA 2114 on other tumors, such as Colon 38 carcinoma, Ca 755 mammary adenocarcinoma and L1210 leukemia, and found that it also had antitumor effects on various kinds of tumors. The nephrotoxicity-inducing activity of DWA 2114 and CDDP was evaluated in normal BDF1 mice, as indicated by changes in blood urea nitrogen (BUN) at almost the maximum tolerated dose (MTD) (DWA 2114: 100 mg/kg, CDDP: 12 mg/kg). DWA 2114 had no effect on BUN levels, while CDDP elevated BUN levels. These results indicate that DWA 2114 represents a second generation platinum antitumor complex.

D001806 Blood Urea Nitrogen The urea concentration of the blood stated in terms of nitrogen content. Serum (plasma) urea nitrogen is approximately 12% higher than blood urea nitrogen concentration because of the greater protein content of red blood cells. Increases in blood or serum urea nitrogen are referred to as azotemia and may have prerenal, renal, or postrenal causes.

D002945 Cisplatin An inorganic and water-soluble platinum complex. After undergoing hydrolysis, it reacts with DNA to produce both intra and interstrand crosslinks. These crosslinks appear to impair replication and transcription of DNA. The cytotoxicity of cisplatin correlates with cellular arrest in the G2 phase of the cell cycle.
