TNFRSF1A/CD120a Inhibitor

Taurohyodeoxycholic acid (THDCA) sodium is the taurine-conjugated form of the secondary bile acid hyodeoxycholic acid. Taurohyodeoxycholic acid can also reduce the activity and expression of myeloperoxidase TNF-α and IL-6, as well as colonic damage in TNBS-induced ulcerative colitis mouse model.

Cudraflavone B is a prenylated flavonoid with anti-inflammatory and anti-tumor properties. Cudraflavone B is also a dual inhibitor of COX-1 and COX-2. Cudraflavone B blocks the translocation of nuclear factor κB (NF-κB) from the cytoplasm to the nucleus in macrophages. Thus, Cudraflavone B inhibits tumor necrosis factor α (TNFα) gene expression and secretion. Cudraflavone B also triggers the mitochondrial apoptotic pathway, activates NF-κB, the MAPK p38, and ERK, and induced the expression of SIRT1. Thus Cudraflavone B inhibits the growth of human oral squamous cell carcinoma cells.

Arucadiol is a rosane-type diterpenoid anti-inflammatory agent. 5 μM Arucadiol significantly inhibits LPS-induced TNF-α, IL-1β, and IL-8 production (inhibition rates of 39.8%, 44.4%, and 34.5%, respectively). Arucadiol exerts its anti-inflammatory activity by inhibiting the mRNA and protein expression of inflammatory cytokines and can be used in research on inflammation-related cardiovascular diseases such as atherosclerosis. Arucadiol can be naturally extracted from the roots of Salvia miltiorrhiza var. alba.
