Protosappanin A (PTA) has anti-oxidative/nitrative activities on brain immune and neuroinflammation through regulation of CD14/TLR4-dependent IKK/IκB/NF-κB inflammation signal pathway; it exerts anti-neuroinflammatory effect by inhibiting JAK2-STAT3 pathway in lipopolysaccharide-induced BV2 microglia. Protosappanin A induces immunosuppression of rats heart transplantation targeting T cells in grafts via NF-kappaB pathway. Protosappanin A and protosappanin B have antimicrobial activity, they show both alone activities and resistance reversal effects of amikacin and gentamicin against MRSA. Protosappanin A shows strong effect against HIV-1 IN with an IC50 value of 12.6 uM.

1. Phellodendrine (Phallodendrin) has anti-nephritic activity, may be due to its ability to inhibit the proliferation or the migration of macrophages and cytotoxic T lymphocytes in the glomeruli.

CL075 (3M002) is a selective TLR8 agonist.CL075 has immunomodulatory activity by triggering the MyD88-dependent signaling pathway, activating NF-κB and IRF7 to elicit the production of inflammatory cytokines and type I interferon (IFN).

Ethacrynic acid (Edecrin) is a nonsulfonamide loop diuretic that inhibits the activity of the Na+/K+/2Cl- cotransporter NKCC2 in the thick ascending limb of the loop of Henle. It also inhibits glutathione S-transferase and Wnt signalling, producing cytotoxicity in chronic lymphocytic leukaemia cells and other tumour cells.

Yangonin (Y100550) is a novel CB receptor ligand, it exhibits affinity for the human recombinant CB receptor. Yangonin (Y100550) could be a valuable candidate for the intervention of NF-κB-dependent pathological conditions such as inflammation.
