生物活性

Balsalazide could suppress colitis-associated carcinogenesis through modulation of IL-6/STAT3 pathway.

IC50 & Target[1][2]

IL-6

 

STAT3

 

体内研究
(In Vivo)

At the endpoint, the protein production of MIP-1β, MCP-1, IL-6, and IL-10 in the colon tissues decrease in concordance with the plasma concentrations of the cytokines. The drug-treated groups reveal lower expression of p-STAT3 compared to the CAC group. In addition, BCL2 decreases and BAX increases markedly in the BSZ+VSL#3 group[1]. Balsalazide is a new 5-aminosalicylic acid (5-ASA) containing prodrug[2].

Animal Administration
[1]

Mice[1]
C57B/L6J mice are randomly divided into four groups: CAC group, Balsalazide (BSZ) group (300 mg/kg), VSL#3 group, and BSZ+VSL#3 group. After two weeks, the AOM/DSS model is induced by AOM injection followed by two cycles of 2% DSS[1].
