Quinoclamine, a naphthoquinone derivative, is a NF-κB inhibitor. Quinoclamine exhibits anti-cancer activity[1][2].

IC50 & Target


In Vitro

Quinoclamine causes differentiation of U-937 cells into macrophage-like cells[1].
Quinoclamine inhibits NF-κB activities in HepG2 cells, with an IC50 of 1.7 μM[2].
Quinoclamine (1-4 μM; 30 minutes ) suppresses endogenous NF-κB activity in HepG2 cells through the inhibition of IκB-α phosphorylation and p65 translocation[2].
Quinoclamine inhibits induced NF-κB activities in lung and breast cancer cell lines[2].
Quinoclamine affects the expression levels of genes involved in cell cycle or apoptosis[2].
Quinoclamine down-regulates the expressions of UDP glucuronosyltransferase genes involved in phase II drug metabolism[2].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
