Rhodionin is an orally active, multifunctional antivirulence and cytoprotective agent that targets and inhibits Lipase, sortase A (SrtA), CYP2D6 (IC50=0.761 μM), AChE (IC50=2.43-57.5 μM), and DPPH free radicals (IC50=19.49 μM). Rhodionin is isolable from the roots of Rhodiola crenulata. Rhodionin reduces postprandial serum triglyceride levels in mice by inhibiting lipase activity. Rhodionin also binds directly to SrtA to inhibit its transpeptidase activity, thereby reducing the fibrinogen adhesion and surface protein A levels of MRSA, effectively inhibiting biofilm formation and protecting against MRSA-induced cell damage. Rhodionin improves the survival rate of infected mice without affecting MRSA growth, and finds wide application in studies related to hyperlipidemia, exogenous obesity, and pneumonia induced by methicillin-resistant Staphylococcus aureus (MRSA) .

Avenanthramide C is an orally active polyphenolic compound that penetrates the blood-brain barrier. Avenanthramide C is derived from oats. Avenanthramide C inhibits NF-κB nuclear translocation and inhibits the phosphorylation of PI3K, PLCγ1, Lyn, Syk, and Akt. Avenanthramide C inhibits the expression and activity of MMP-9 and inhibits MAPK phosphorylation. Avenanthramide C scavenges DPPH radicals, reduces intracellular ROS, and inhibits pro-inflammatory cytokine release and adhesion molecule expression. Avenanthramide C inhibits cell degranulation. Avenanthramide C attenuates active systemic anaphylaxis and inhibits passive cutaneous anaphylaxis. Avenanthramide C ameliorates PHZ-induced blood stasis. Avenanthramide C inhibits neuroinflammation, restores long-term potentiation, and improves recognition and spatial memory in Alzheimer's disease models. Avenanthramide C can be used for research on allergic inflammation, thrombosis, atherosclerosis, and Alzheimer's disease .

CAS No.: 1898-66-4
Synonyms: 2,2-Diphenyl-1-picrylhydrazyl (Standard)
DPPH (Standard) is the analytical standard of DPPH. This product is intended for research and analytical applications. DPPH (2,2-Diphenyl-1-picrylhydrazyl) is a stable free radical that can be used to measure the radical scavenging activity of antioxidants. The odd electron of nitrogen atom in DPPH is reduced by receiving a hydrogen atom from antioxidants to the corresponding hydrazine. DPPH method may be utilized in aqueous and nonpolar organic solvents and can be used to examine both hydrophilic and lipophilic antioxidants .
