Minaprine
Minaprine is a brain-penetrant monoamine oxidase inhibitor. Minaprine also weakly inhibits acetylcholinesterase (AChE) activity. Minaprine reduces intraneuronal dopamine metabolism, lowers striatal homovanillic acid and dihydroxyphenylacetic acid levels, and raises striatal 3-methoxytyramine and 5-hydroxytryptamine levels. Minaprine exhibits convulsant, antidepressant properties.

AChE |
Minaprine (5×10-4 M) does not interact with dopaminergic receptors in rat striatal membranes, as it fails to displace [3H]spiperone binding[1].
Minaprine (40-160 μM) does not alter choline acetyltransferase activity in rat striatal or hippocampal tissue preparations in vitro[2].
Minaprine (40-160 μM) inhibits acetylcholinesterase activity in rat striatal and hippocampal tissue preparations in vitro[2].
Minaprine weakly displaces (3H) dexetimide from specific muscarinic receptors in rat striatal homogenates in vitro, with an IC50 of 2×10-4 M[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Minaprine (7.5-30 mg/kg; i.p.; single dose or once daily for 10 consecutive days) dose-dependently increases acetylcholine levels in multiple rat brain regions[2].

Result:Reduced striatal DOPAC to 403 ± 32 ng/g wet tissue (P < 0.01 vs control) and increased 3-MT to 19.1 ± 1.2 ng/g wet tissue at 2.5 mg/kg, 30 minutes post-administration.
Reduced striatal DOPAC to 364 ± 11 ng/g wet tissue (P < 0.01 vs control) and increased 3-MT to 24.5 ± 3.5 ng/g wet tissue (P < 0.05 vs control) at 5 mg/kg, 30 minutes post-administration.

Reduced striatal HVA to 321 ± 34 ng/g wet tissue (P < 0.01 vs control) and DOPAC to 239 ± 25 ng/g wet tissue (P < 0.01 vs control), and increased 3-MT to 43.6 ± 2.8 ng/g wet tissue (P < 0.01 vs control) at 15 mg/kg, 30 minutes post-administration.
Reduced striatal HVA to 312 ± 16 ng/g wet tissue (P < 0.01 vs control) and DOPAC to 241 ± 12 ng/g wet tissue (P < 0.01 vs control), and increased 3-MT to 56.6 ± 2.3 ng/g wet tissue (P < 0.01 vs control) at 30 mg/kg, 30 minutes post-administration.
Reduced striatal HVA to 283 ± 13 ng/g wet tissue (P < 0.05 vs control) and DOPAC to 471 ± 13 ng/g wet tissue (P < 0.01 vs control), and increased 3-MT to 66 ± 5 ng/g wet tissue (P < 0.01 vs control) at 15 mg/kg, 15 minutes post-administration.
Reduced striatal HVA to 190 ± 26 ng/g wet tissue (P < 0.01 vs control) and DOPAC to 288 ± 14 ng/g wet tissue (P < 0.01 vs control), and increased 3-MT to 86 ± 8 ng/g wet tissue (P < 0.01 vs control) at 15 mg/kg, 30 minutes post-administration.
Reduced striatal HVA to 222 ± 28 ng/g wet tissue (P < 0.01 vs control) and DOPAC to 339 ± 57 ng/g wet tissue (P < 0.01 vs control), and increased 3-MT to 73 ± 14 ng/g wet tissue (P < 0.01 vs control) at 15 mg/kg, 60 minutes post-administration.
Reduced striatal HVA to 231 ± 24 ng/g wet tissue (P < 0.01 vs control) and DOPAC to 488 ± 21 ng/g wet tissue (P < 0.01 vs control), and increased 3-MT to 41 ± 3 ng/g wet tissue (P < 0.01 vs control) at 15 mg/kg, 90 minutes post-administration.

Did not alter pargyline-induced changes in striatal HVA, DOPAC, or 3-MT levels when administered 5 minutes after Pargyline (HY-A0091A) (100 mg/kg i.p.) at 15 mg/kg.
Did not significantly alter striatal DA concentrations at any dose or time point tested.

Animal Model:CD-COBS (female, 200-300 g)[2]
-
Dosage:7.5 mg/kg; 15 mg/kg; 30 mg/kg; 15 mg/kg (daily for 10 days) followed by 30 mg/kg (challenge dose)
-
Administration:i.p.; single dose or once daily for 10 consecutive days
-
Result:Showed no significant change in striatal acetylcholine or choline levels at 7.5 mg/kg.
Produced a 17% increase in striatal acetylcholine levels; showed no change in choline levels at 15 mg/kg.
Produced a 59% increase in striatal acetylcholine levels, which persisted for at least 2 h; decreased striatal choline levels by 20% (significant only at 30 min post-administration) at 30 mg/kg.
Increased acetylcholine levels by 35% in the hippocampus, 14% in the midbrain-hindbrain, and 37% in the forebrain (excluding striatum and hippocampus), without altering choline levels in these regions at 30 mg/kg.
Caused an 18% inhibition of striatal acetylcholinesterase activity at 5 min post-administration (corresponding to peak brain drug levels), which resolved by 30 min at 30 mg/kg.
Showed no change in choline acetyltransferase activity after in vivo administration of 30 mg/kg.
Produced an increase in striatal acetylcholine comparable to that seen in drug-naive rats (no tolerance) after 10 days of daily 15 mg/kg treatment followed by a 30 mg/kg challenge dose.
