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.

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.

Octopamine hydrochloride ((±)-p-Octopamine hydrochlorid) is a biogenic monoamine structurally associated with noradrenaline. It can serve as a neurohormone, a neurotransmitter, and a neuromodulator in invertebrates.

4-aminobenzoic acid is an organic acid with UV-absorbing and antifibrotic properties. When exposed to light, 4-aminobenzoic acid absorbs UV light and releases excess energy through a photochemical reaction, which may cause DNA damage.4-aminobenzoic acid also increases oxygen uptake at the tissue level and may enhance monoamine oxidase (MAO) activity to promote serotonin degradation, which in excess may lead to fibrotic Changes.

Serotonin hydrochloride (Serotonin HCl) is an endogenous 5-HT receptor agonist, a monoamine neurotransmitter in the CNS, and a catechol O-methyltransferase (COMT) inhibitor(Ki=44 μM).

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

Ethyl 4-hydroxyphenylacetate is a selective inhibitor of monoamine oxidase A.

Tyramine (Uteramine) is an indirect sympathomimetic that occurs naturally in cheese and other foods. Tyramine does not directly activate adrenergic receptors, but it can serve as a substrate for adrenergic uptake systems and MONOAMINE OXIDASE to prolong the actions of adrenergic transmitters. It also provokes transmitter release from adrenergic terminals and may be a neurotransmitter in some invertebrate nervous systems.

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

It is an isomer of cresotinic acid (2-hydroxy-3-methylbenzoic acid) and oxymethylbenzoic acid (2-methoxybenzoic acid). Derivatives of mandelic acid are formed as a result of metabolism of adrenaline and noradrenaline by monoamine oxidase and catechol-o-methyl transferase. It is also present in certain skin care products, is an intermediate molecule in the production of other biochemicals, may be used as an analytical reagent and is a precursor in the manufacture of dyes. Mandelic acid (acidomandelico) is found to be associated with phenylketonuria, which is an inborn error of metabolism.

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.

Tetrahydroharmine (Leptaflorine) is a natural product found in the stems and large branches of Banisteriopsis caapi cultivar Da Vine. Tetrahydroharmine is a Monoamine oxidase A inhibitor.

Jatrorrhizine (neprotin) is a protoberberine alkaloid isolated from Enantia chlorantha (Annonaceae) and other species. It was found to have antimicrobial and antifungal activity. It binds and noncompetitively inhibits monoamine oxidase (IC50 4 micromolar for MAO-A and 62 for MAO-B).

Glicoricone acts as a partial estrogen antagonist. Glicoricone inhibited the monoamine oxidase with the IC50 values of 6.0 x 10(-5)-1.4 x 10(-4) M.

Cudratricusxanthone A has potent anti-proliferative, antioxidative, and monoamine oxidase inhibitory effects, it also possesses anti-cancer activities and provide a basis for developing effective therapeutic agents to inhibit growth and metastasis of brea

Hyperforin, a natural product from Hypericum, is commonly used as an antidepressant and also has neurological, inflammatory, antimicrobial, antitumor and antiangiogenic effects. Hyperforin acts as a monoamine reuptake inhibitor (MRI) in vitro, including serotonin, norepinephrine, dopamine, GABA, and glutamate, with an IC 50 of ≈0.1 μg mL. Hyperforin is also capable of inducing the cytochrome P450 enzymes, CYP3A4 and CYP2C9, through binding to and activation of the pregnane X receptor. Hyperforin is capable of activating TRPC6 channels by binding to a specific motif.

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

Glycyrrhisoflavone is a tyrosinase inhibitor with anti-inflammatory effects. Glycyrrhisoflavone inhibits α-glucosidase and monoamine oxidase.

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.

Tryptamine is a monoamine alkaloid found in animals, plants, and fungi. It contains an indole ring structure and is structurally analogous to the tryptophan. It is found in trace amounts in the brains of mammals and is recognized to play a role as a neuro

Rubrofusarin triglucoside, a glycoside isolated from Cassia obtusifolia Linn seeds, demonstrates inhibitory activity against human monoamine oxidase A (hMAO-A), exhibiting an IC50 value of 85.5 μM[1].

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