IKK-2 17.9 nM (IC50) |
STAT3 |
TPCA-1 inhibits lipopolysaccharide-induced human monocyte production of TNF-α, IL-6, and IL-8 with an IC50 of 170 to 320 nM[1][2].
TPCA-1 (0-2 μM) inhibits STAT3 phosphorylation and transactivation induced by cytokines and nonreceptor tyrosine kinase in dose- and time-dependent manner. TPCA-1 completely inhibits STAT3 phosphorylation without changing total STAT3 levels[3].
TPCA-1 increased sensitivity to ZD1839 in both TKI sensitive cells and insensitive cells[3].
