详细说明

Selleck Chemicals - S2320

Research Area: Inflammation
Biological Activity:
Luteolin is a PDE4 inhibitor and a general phosphodiesterase inhibitor, and an Interleukin 6 inhibitor. It significantly reversed the xylazine/ketamine-induced anesthesia in mice. Luteolin is a flavonoid; more specifically, it is one of the more common flavones. It is thought to play an important role in the human body as an antioxidant, a free radical scavenger, an agent in the prevention of inflammation, a promoter of carbohydrate metabolism, and an immune system modulator. These characteristics of luteolin are also believed to play an important part in the prevention of cancer. [1]References on Luteolin[1] http://en.wikipedia.org/wiki/Luteolin , ,

Biochem/physiol Actions
Hydroxylated flavone derivative, a strong antioxidant and radical scavenger. Suggested to play a role in prevention of cancer, possibly via the inhibition of fatty acid synthase activity.

Toronto Research Chemicals - L475000

Hydroxylated flavone derivative with strong anti-oxidant and radical scavenging properties. Suggested to play a role in cancer prevention.
