S3298^New	Caulophylline (N-Methylcytisine) Caulophylline (N-Methylcytisine, Caulophyllin, NMC) is a tricyclic quinolizidine alkaloid with anti-inflammatory activities. Caulophylline binds to nicotinic acetylcholine receptors (nAChR) from squid optical ganglia with Kd of 50 nM. Caulophylline significantly reduces myeloperoxidase (MPO) activity, blocks the activation of NF-κB by inhibiting IκB and IKK phosphorylation.
S0002^New	IAXO-102 IAXO-102 is an antagonist of TLR4 targeting both MD-2 and CD14 co-receptors. IAXO-102 inhibits MAPK and p65 NF-κB phosphorylation and downregulates the expression of TLR4 dependent proinflammatory proteins. IAXO-102 inhibits experimental abdominal aortic aneurysm (AAA) development.

S2371	Vanillylacetone Vanillylacetone (NSC 15335) is similar in chemical structure to other flavor chemicals such as vanillin and eugenol and is used as a flavor additive in spice oils and in perfumery to introduce spicy aromas. Vanillylacetone (Zingerone) alleviates oxidative stress and inflammation, down-regulates NF-κB mediated signaling pathways. Zingerone acts as an anti-mitotic agent, and inhibits the growth of neuroblastoma cells.
