Product Description
Clorgyline, formerly known as Clorgiline, M&B 9302 or MB9302, is a potent, irreversible and selective inhibitor of monoamine oxidase (MAO), it is structurally related to pargyline which is described as an antidepressant. Specifically, it is an irreversible (covalent) and selective inhibitor of monoamine oxidase A (MAO-A). Clorgiline was never marketed, but it has found use in scientific research. In addition to its actions as an MAOI, clorgiline has been found to bind with high affinity to the σ1 receptor (Ki = 3.2 nM) and with very high affinity to the I2 imidazoline receptor (an allosteric site on the monoamine oxidase enzyme) (Ki = 40 pM).
Clorgyline hydrochloride is a potent, irreversible, and selective inhibitor of monoamine oxidase A (MAO-A). It preferentially targets MAO-A over MAO-B, with Ki values of 0.054 µM and 58 µM, respectively. The compound has IC50 values of 0.0012 µM and 1.9 µM for MAO-A and MAO-B, respectively. Clorgyline is without effect on serotonin receptors, but it does inhibit the sigma receptor σ1 on Jurkat human T lymphocyte cells with an IC50 of 31 nM. It has a molecular formula of C13H15Cl2NO·HCl and a molecular weight of 308.6.
Biological Activity I Assay Protocols (From Reference)
Targets
Clorgyline hydrochloride targets monoamine oxidase A (MAO-A) and the sigma receptor σ1. It acts as an irreversible inhibitor of MAO-A, binding covalently to the enzyme and preventing the breakdown of monoamines such as serotonin, norepinephrine, and dopamine. It also inhibits the sigma receptor σ1 on Jurkat human T lymphocyte cells.
ln Vitro
In vitro, Clorgyline hydrochloride is a potent and selective inhibitor of MAO-A. It inhibits MAO-A with a Ki of 0.054 µM and MAO-B with a Ki of 58 µM. It also inhibits the sigma receptor σ1 with an IC50 of 31 nM. By inhibiting MAO-A, it prevents the breakdown of monoamines, making it a valuable tool for studying the regulation of mood, anxiety, and neurodegenerative diseases.
ln Vivo
In vivo, Clorgyline hydrochloride is used as a research tool to study the role of MAO-A in various physiological and pathological processes. It has been used in neuropharmacology and psychiatric research. By inhibiting MAO-A, it increases the levels of monoamines in the brain, which can affect mood and behavior. It is not marketed as a therapeutic agent.
Enzyme Assay
Clorgyline hydrochloride is evaluated in cell-free enzymatic assays using purified MAO-A and MAO-B enzymes. The compound is incubated with the enzyme and a substrate, and the inhibition of enzyme activity is measured. IC50 and Ki values are determined to quantify the potency and selectivity of MAO-A inhibition. Sigma receptor binding assays are also performed.
Cell Assay
Clorgyline hydrochloride is assessed in cell-based assays using cell lines expressing MAO-A or sigma receptors. Cells are treated with Clorgyline, and MAO-A activity is measured by assessing the metabolism of monoamines. Sigma receptor activity is assessed by measuring receptor-mediated signaling pathways.
Animal Protocol
Clorgyline hydrochloride is administered in animal models to evaluate its effects on MAO-A activity and behavior. It is used to study the role of MAO-A in mood regulation, anxiety, and neurodegenerative diseases. Efficacy is assessed by measuring monoamine levels in the brain and by behavioral tests.
ADME/Pharmacokinetics
Clorgyline hydrochloride has a molecular weight of 308.6 and a molecular formula of C13H15Cl2NO·HCl. It has a CAS number of 17780-75-5. The compound is a powder with a purity of ≥95%. It should be stored under recommended conditions.
Toxicity/Toxicokinetics
Clorgyline hydrochloride is an irreversible inhibitor of MAO-A. No detailed toxicity data is available for this compound beyond its use as a research tool. It is for research use only and is not intended for human therapeutic use.

Additional Infomation
Clorgyline is an aromatic ether, a 2,4-dichlorophenyl ether of 3-aminoprop-1-ol, wherein the nitrogen atom is replaced by a methyl group and a prop-1-yn-3-yl group. It is a monoamine oxidase inhibitor and was formerly used as an antidepressant. It has a dual role as an EC 1.4.3.4 (monoamine oxidase) inhibitor and an antidepressant. It is a tertiary amine compound, a terminal alkyne compound, an aromatic ether, and a dichlorobenzene.
