Eupalestin	Structural Classification Flavonoids Flavones Lupinus perennis L. Plants Compositae Source Classification	NF-κB p38 MAPK Adenosine Deaminase Interleukin Related
Eupalestin is an anti-inflammatory agent. Eupalestin reduces the levels of p-p65 NF-κB and p-p38 MAPK. Eupalestin inhibits MPO and adenosine deaminase. Eupalestin decreases the levels of pro-inflammatory cytokines including IL-17A, IL-6, TNF and IFN-γ. Eupalestin exerts anti-inflammatory activity in a carrageenan (HY-125474)-induced mouse pleurisy model .

HY-100807S

Quinolinic acid-d3 2 Publications Verification
Quinolinic acid-d₃ is the deuterium labeled Quinolinic acid. Quinolinic acid, an endogenous metabolite of tryptophan, is a N-methyl-D-aspartate receptor (NMDA receptor) agonist. Quinolinic acid increases glutamate efflux, induces the generation of ROS, activates nitric oxide synthase, produces excessive NO, leading to calcium ion influx and neuronal apoptosis.

HY-100807S2

Quinolinic acid-13C4,15N
Quinolinic acid-13C4, 15N is an isotopic labeled Quinolinic acid (HY-100807). Quinolinic acid, an endogenous metabolite of tryptophan, is a N-methyl-D-aspartate receptor (NMDA receptor) agonist. Quinolinic acid increases glutamate efflux, induces the generation of ROS, activates nitric oxide synthase, produces excessive NO, leading to calcium ion influx and neuronal apoptosis.

HY-100807S1

Quinolinic acid-13C7
Quinolinic acid- ¹³C₇ is the ¹³C labeled Quinolinic acid (HY-100807). Quinolinic acid, an endogenous metabolite of tryptophan, is a N-methyl-D-aspartate receptor (NMDA receptor) agonist. Quinolinic acid increases glutamate efflux, induces the generation of ROS, activates nitric oxide synthase, produces excessive NO, leading to calcium ion influx and neuronal apoptosis.

HY-138166S

Rosuvastatin lactone-d6

Rosuvastatin lactone-d₆ is the deuterium labeled Rosuvastatin lactone. Rosuvastatin lactone is a metabolite of Rosuvastatin (HY-17504A), a statin lipid-lowering agent and HMG-CoA inhibitor. Rosuvastatin lactone exhibits endothelium-independent and HMG-CoA reductase-independent vasorelaxant activity in rat aortic rings, and its vasorelaxant effect is jointly mediated by NO produced by inducible nitric oxide synthase (iNOS) located in vascular smooth muscle and activation of potassium channels. Rosuvastatin lactone itself has no lipid-lowering effect .

HY-163712S

17-Epiestriol-d5-1

17-Epiestriol-d₅-1 is the deuterium labeled 17-Epiestriol (HY-163712). 17-Epiestriol is an estrogen metabolite and a selective estrogen receptor (ER) β agonist. 17-epiestriol inhibits the mRNA and protein expression of the vascular cell adhesion molecule VCAM-1 induced by tumor necrosis factor α (TNFα). 17-epiestriol also inhibits TNFα-induced VCAM-1 expression and prevents NF-κB migration to the nucleus. 17-Epiestriol also induces the mRNA and protein expression of endothelial nitric oxide synthase .
