monoamineoxidase

Norharmane (β-Carboline) is a natural β-carboline first isolated from plants of the Zygophyllaceae family.

Harmane (Loturine) is a bio-active β-Carboline and monoamine oxidase inhibitor found in coffee and tobacco smoke.

Obtusin is a natural product.

Rosiridin (6'-O-Deacetylrosiridoside C) has cardioprotective activity.

Osthenol is a natural product, and is selective, reversible, and competitive human monoamine oxidase-A (hMAO-A) inhibitor (Ki=0.26 µM).It shows antitumor-promoting activity, it also has antifungal and antibacterial activities.

Methylpiperic acid, a piperine alkaloid, exhibits potent inhibitory activity on monoamine oxidase (MAO), with differing efficacy on isoforms: greater inhibition of MAO-A (IC 50 27.1 μM) compared to MAO-B (IC 50 1.6 μM), indicative of its bidirectional inhibition. Moreover, it is applied in the treatment of mental disorders [1].

β-Aminopropionitrile (3-Aminopropionitrile) is a selective inhibitor of lysyl oxidase.

Tovopyrifolin C is a naturally occurring flavonoid found in a variety of plants that inhibits monoamine oxidase (IC50=2.7 µM).

Hypericin (Cyclosan) is a natural anthraquinone compound, an extract of Hypericum perforatum, which inhibits PKC, MAO, dopamine-beta-hydroxylase, reverse transcriptase, telomerase, and CYP, etc. Hypericin exhibits antimicrobial, antiviral, antitumor, and antidepressant activities.

1H-pyrazole (1,2-Diazole), is a versatile building block, with a vast applications in organic synthesis. The derivatives of Pyrazole are used in medicine, for their analgesic, anti-inflammatory, antipyretic, antiarrhythmic, tranquilizing, muscle relaxing, psychoanaleptic, anticonvulsant, monoamineoxidase inhibiting, antidiabetic and antibacterial activities.

Paeonol (Peonol) is an active extraction from Paeonia suffruticosa. Paeonol inhibits MAO-A and MAO-B with IC50 of 54.6 μM and 42.5 μM, respectively.

Rosmarinic acid (Labiatenic acid) is widely found in plants and has antioxidant, anti-inflammatory, and antibacterial activities. It inhibits MAO-A, MAO-B, and COMT with IC50 of 50.1, 184.6, and 26.7 μM respectively.

Isatin (2,3-Indolinedione) is an endogenous MAO inhibitor.

Harmol, a β-carboline alkaloid, is a monoamine oxidase inhibitor that can be used as an analytical reference standard.

1. Desmethoxyyangonin (5,6-Dehydrokavain) protects LPS or LPS D-GalN-induced damages in cell or liver tissues mainly through de-regulating IKK NFκB and Jak2 STAT3 signaling pathways. 2. The induction of CYP3A23 by dihydromethysticin and Desmethoxy yangonin involves transcription activation, probably through a PXR-independent or PXR-involved indirect mechanism.
