kappa-opioid

Lumichrome is an endogenous compound in humans, produced by photodegradation of riboflavin. It utilizes a p53-dependent mechanism to inhibit growth and induce apoptosis in human lung cancer cells.

Matrine (Vegard), an alkaloid isolated from the Sophora genus, acts as a kappa opioid receptor agonist.

Amentoflavone (3',8''-Biapigenin), as a potent inhibitor of CYP3A4 and CYP2C9, can interact with many other medications. CYP3A4 and CYP2C9 are proteins used for drug metabolism in the body. Amentoflavone also is an inhibitor of human cathepsin B. It has antimalarial activity in trials significant affinities towards the Delta-1, kappa opioid receptors (as an antagonist) and binds to benzodiazepine receptors. Amentoflavone may be a potential lead for a new type of anti-inflammatory agents having the dual inhibitory activity of group II phospholipase A2 and cyclooxygenase. Amentoflavone and quercetin differentially exerted suppression of PGE2 biosynthesis via downregulation of COX-2/iNOS expression.

Matrine (Standard) is the standard substance of Matrine, and it is applicable for quantitative analysis, quality control, and related research in biochemical experiments. Matrine (Vegard), an alkaloid isolated from the Sophora genus, acts as a kappa opioid receptor agonist.

Akuammidine shows anti-inflammatory and anti-asthmatic properties, it has opioid analgesic activity, it shows a preference for mu-opioid binding sites with Ki values of 0.6, 2.4 and 8.6 microM at mu-, delta- and kappa-opioid binding sites, respectively.

Akuammigine has in vitro antimalarial activity. Akuammigine competitively antagonizes the effect of noradrenaline on postsynaptic alpha-adrenoceptors, yielding pA2 values of 4.68. Akuammidine also shows a preference for mu-opioid binding sites with Ki val
