Clorgyline (M&B 9302) is a selective, irreversible monoamine oxidase A (MAO-A) inhibitor that can cross the blood-brain barrier and exhibits activity against the 5-HT Receptor at very high doses. Clorgyline regulates monoamine neurotransmitter levels, the release of dopamine and acetylcholine, the uptake and effects of Tyramine (HY-W007606), noradrenergic function, circadian locomotor activity rhythms, feeding behavior, and body weight. Clorgyline induces tumor-suppressive transcriptional programs, secretory differentiation, androgen signaling regulation, Bcl-2 expression, and radioprotective effects in non-malignant cells. Clorgyline is used in the research of high-grade prostate cancer, Huntington's disease, major affective disorder, radiation-induced normal tissue toxicity, and obesity.

In Vitro

Clorgyline (M&B 9302) potently inhibits MAO activity in rat intestinal mitochondrial preparations, with an ID₅₀ of 80 nM^[1].
The inhibitory effect of Clorgyline on acetylcholine release from isolated rat striatal brain slices is irreversible after washout^[1].
Clorgyline (5 min) enhances dopamine release from striatal synaptosomes in CFY rats within 5 minutes^[1].
Clorgyline (5 min pre-incubation) inhibits monoamine oxidase activity in the mouse cerebral cortex in vitro, and the combined use of Clorgyline and Pargyline (HY-A0091A) produces a stronger inhibitory effect than Clorgyline alone^[7].
Clorgyline (M&B 9302) (1 μM; 6-96 hr) significantly upregulates 156 genes in E-CA-88 high-grade prostate cancer cells and induces an antitumor transcriptional program that counteracts beta-catenin, ERBB2, and other oncogenic pathways, while promoting secretory differentiation by upregulating AR, PSA, and polycomb-repressed genes^[2].
Treatment with Clorgyline (1 μM; 6-96 hr) reduces the clonogenic proliferative capacity of two high-grade prostate cancer cell lines, E-CA-88 and E-CA-90, which is consistent with a pro-differentiation effect^[2].
Clorgyline (1 μM; 24-96 hr) upregulates oncogenic pathway suppressors, secretory differentiation markers, and Polycomb-repressed genes, while downregulating EZH2 in E-CA-90 high-grade prostate cancer cells. This confirms that the effects observed in E-CA-88 cells are reproducible in independent primary high-grade prostate cancer cultures^[2].
Clorgyline (1 nM; 6 h before irradiation) exerts a radioprotective effect in non-malignant HaCaT cells exposed to 0.5 and 5 Gy of ⁶⁰Co γ radiation, whereas it shows no radioprotective effect in tumorigenic HaCaT-ras, HPV-G, and PC3 cell lines^[5].
Clorgyline (1 nM; 6 h before irradiation) protects the progeny of irradiated non-malignant HaCaT cells from delayed reproductive death, while its protective effect on the tumorigenic HaCaT-ras and HPV-G cell lines is much weaker, and it reduces the survival rate of the progeny of unirradiated tumor cells^[5].
Clorgyline (1 nM; 6 h before irradiation) increases Bcl-2 protein expression in non-malignant HaCaT cells both under non-irradiated conditions and after exposure to 0.5 or 5 Gy ⁶⁰Co γ-ray irradiation^[5].
Clorgyline (1 nM; 6 h before irradiation) increases Bcl-2 protein expression in primary normal human urothelial explants^[5].

In Vivo

Clorgyline (M&B 9302) (0.25 mg/kg; subcutaneous injection; single dose) inhibits intestinal MAO in rats in vivo, with an ID₅₀ of 0.25 mg/kg for subcutaneous administration^[1].
Clorgyline (0.5-3 mg/kg; i.p.; once daily; for 28 days) inhibits cortical MAO-A activity by approximately 80% in wild-type FVB/N mice, elevates the levels of 5-hydroxytryptamine and norepinephrine in the striatum, and reduces DOPAC levels; the 3 mg/kg dose causes body weight loss and decreases the immobility time of mice in the tail suspension test^[3].
Clorgyline (1.5 mg/kg; i.p.; once daily; for 26 days) inhibits approximately 90% of cortical MAO-A, restores striatal monoamine neurotransmitter levels, and alleviates anxiety-like and depression-like behaviors in YAC128 Huntington's disease mice^[3].
Administration of Clorgyline (0.5-8 mg/kg/day; subcutaneous injection; via osmotic minipump; 14 days to 7 weeks) dose-dependently delays the onset of running wheel activity in Syrian hamsters under LD 14:10 conditions, with a 1.5-hour delay observed at a dose of 2 mg/kg/day after 7 days^[6].
Clorgyline (2 mg/kg/day; subcutaneous injection; via osmotic minipump; 6 weeks) slows the rate of re-entrainment of wheel-running activity rhythms to short photoperiods in Syrian hamsters, but does not prevent short photoperiod-induced testicular regression^[6].
The phase delay of spontaneous locomotor activity induced by Clorgyline (2 mg/kg/day; subcutaneous injection; via osmotic minipump; administration initiated 3 days before exposure to constant darkness) persists under constant darkness conditions, with both the onset and offset of activity delayed, indicating an effect on the central circadian pacemaker^[6].
Acute administration of Clorgyline (12-96 mg/kg; single injection; in combination with Pargyline) produces transient, dose-dependent anorectic effects and MAO inhibition in normal mice, whereas chronic administration (24 mg/kg; once-weekly injection; for 12 weeks) does not alter long-term food intake or body weight^[7].
Clorgyline (24 mg/kg; weekly injection; for 12 weeks; in combination with Pargyline) produces a sustained 12% reduction in food intake and body weight in ob/ob obese mice, and this effect persists after treatment discontinuation. In contrast, a single administration (24-96 mg/kg; single injection) potently inhibits MAO and elevates monoamine levels but does not affect food intake^[7].
Clorgyline (single injection; used in combination with Pargyline) reduces food intake and body weight in normal rats^[7].
Clorgyline (single injection; used in combination with Pargyline) reduces food intake, water intake, and body weight in normal golden hamsters^[7].
Clorgyline (single injection; used in combination with Pargyline) reduces food intake and body weight in normal Chinese hamsters^[7].
Clorgyline (0.5-1 mg/kg; i.p.; once daily; for 1-21 days) exerts a potent, sustained, and selective inhibitory effect on MAO-A in the brain (on day 21, at a dose of 1.0 mg/kg/day, MAO-A activity decreases to 0% of the control level, while MAO-B activity remains at ~78-95% of the control level). This effect is accompanied by a sustained elevation of norepinephrine levels in the brain, transient 2-fold increases in serotonin and dopamine levels, and no changes in tryptophan or tyrosine hydroxylase activity after 21 days^[8].
Clorgyline (1-10 mg/kg; i.p.; single dose), when administered as a single agent, almost completely inhibits brain monoamine oxidase-mediated serotonin oxidation at doses of 5 mg/kg and above. However, even after subsequent administration of L-tryptophan (HY-N0623), it does not induce hyperactivity or produce maximal brain serotonin accumulation^[9].
When Clorgyline (1-2.5 mg/kg; i.p.; single dose) is co-administered with Deprenil at 2.5 mg/kg each, type A and type B brain monoamine oxidase are almost completely inhibited, resulting in massive accumulation of 5-hydroxytryptamine in the brain and the occurrence of hyperactivity following L-tryptophan challenge^[9].

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Protocol 1

Add each solvent one by one: 10% DMSO 90% Corn Oil

Solubility: ≥ 2.5 mg/mL (9.19 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
