生物活性

Tretazicar (CB 1954), an antitumor prodrug, is highly selective against the Walker 256 rat tumour line. Tretazicar is enzymatically activated to generate a bifunctional agent, which can form DNA-DNA interstrand cross-links. Tretazicar in rat cells involves the reduction of its 4-nitro group to a 4-hydroxylamine by the enzyme NAD(P)H:quinone oxidoreductase 1 (NQO1).

体外研究

Tretazicar (CB 1954) (0.1-1000 μM; 3 days) has sensitivity for retrovirally transduced AB22 (AB22-nr) cells with an IC50 of 3 μM.
DNA cross-link formation in affected cells is a result of the bioactivation of the drug by the enzyme DT diaphorase (NAD(P)H dehydro-genase (quinone)) in the Walker cells which reduces the 4-nitro group of Tretazicar. The product of this reaction is a difunctional alkylating agent, 5-aziridin-1-yl-4-hydroxylamino-2-nitrobenzamide.

体内研究

Tretazicar (CB 1954) (80 mg/kg; i.p. on days 2 and 9) results in a significant increase in survival.

Animal Model: Female BALB/c mice (AB22-nr, SKOV3 human ovarian tumour xenograft)
Dosage: 80 mg/kg
Administration: i.p. on days 2 and 9
Result: The median survival of the AB22-nr was 49 days. Resulted in a significant increase in survival.
