Na+/K+ ATPase Modulator

4-PSQ is an orally active neuroprotective agent. 4-PSQ possesses both antioxidant and anti-inflammatory activities. 4-PSQ improves cognitive impairment and depressive- and anxiety-like emotional abnormalities in mice by regulating the activity of Na⁺, K⁺-ATPase, the NFκB signaling pathway, and the expression of p21. 4-PSQ can be used for the research of neurological diseases.

Strictosamide is a compound that can be isolated from Nauclea officinalis. Strictosamide has various activities such as anti-inflammatory, analgesic, anti-Plasmodium, antifungal, and promoting wound healing.

Citreoviridin, a toxin from Penicillium citreoviride NRRL 2579, inhibits brain synaptosomal Na⁺/K⁺-ATPase whereas in microsomes, both Na⁺/K⁺-ATPase and Mg²⁺-ATPase activities are significantly stimulated in a dose-dependent manner. Citreoviridin inhibits cell proliferation and enhances apoptosis of human umbilical vein endothelial cells.

Citreoviridin-¹³C₂3 is ¹³C labeled 2,3-Pentanedione (HY-W012998). 2,3-Pentanedione is a common constituent of synthetic flavorings and is used to impart a butter, strawberry, caramel, fruit, rum, or cheese flavor in beverages, ice cream, candy, baked goods, gelatins, and puddings. 2,3-Pentanedione also occurs naturally as a fermentation product in beer, wine, and yogurt and is releasedduring roasting of coffee beans.

JAK05 exhibits inhibitory activity against Helicobacter pylori, inhibits strains J63, J196 and J107 with MIC of 3-5 µg/mL. JAK05 exhibits binding affinity to H+/K+-ATPase, COX-1/2, TNF-α and PGE2, reveals antioxidant and anti-inflammatory activities. JAK05 exhibits anti-ulcer activity in rat ethanol-induced gastric ulcer models.
