MedKoo CAT#: 333093

CAS#: 168706-29-4

Description: Cynandione A is an acetophenone isolated from Cynanchum Wilfordii Radix. Cynandione A inhibit inflammation through macrophageal α7 nAChR activation and subsequent IL-10 expression. Cynandione A inhibits hepatic de novo lipogenesis by activating the LKB1/AMPK pathway in HepG2 cells. Cynandione A inhibits lipopolysaccharide-induced cell adhesion via suppression of the protein expression of VCAM‑1 in human endothelial cells. Cynandione A attenuates lipopolysaccharide-induced production of inflammatory mediators via MAPK inhibition and NF-κB inactivation in RAW264.7 macrophages and protects mice against endotoxin shock.
