生物活性

Ochromycinone ((Rac)-STA-21) is a natural antibiotic and a STAT3 inhibitor. Ochromycinone can inhibits STAT3 DNA binding activity, STAT3 dimerization. Ochromycinone has anticancer and antimicrobial activity[1][2].

IC50 & Target[2]

STAT3

 

体外研究
(In Vitro)

STA-21 inhibits STAT3 DNA binding activity, STAT3 dimerization, and STAT3-dependent luciferase activity. Moreover, STA-21 reduces the survival of breast carcinoma cells with constitutive STAT3 signaling but has minimal effect on the cells in which constitutive STAT3 signaling is absent[2].

Shanghai Jinpan Biotech Co Ltd has not independently confirmed the accuracy of these methods. They are for reference only.
