Related Catalog	Research Areas >> Cancer Signaling Pathways >> Others >> Others
In Vivo	Diaziquone (6.75mg /sq m daily for 5 consecutive days or single-dose 26 mg/sq m) has a broad range of activity of diaziquone against primary nervous system tumors and has enhancement effect combined with either 1,3-bis(2-chloroethyl)-1-nitrosourea or procarbazine in athymic mice[1]. Animal Model: Homozygous nu/nu BALB/c athymic mice[1] Dosage: 6.75mg /sq m or 26 mg/sq m Administration: 6.75mg /sq m daily for 5 consecutive days or single-dose 26 mg/sq m Result: Showed rapid clearance in the plasma of athymic mice with a half-life of approximately 11.5 min. Produced significant growth delays. Produced significant increases in the median growth delay, significant increases in the number of tumor regressions.
