We have previously reported that piperine, a known piperidine alkaloid from Piper longum, competitively inhibited mouse brain MAO-A and MAO-B activities. Piperine also showed in vivo antidepressant-like activity against the tail suspension test. In the present study, we further expanded on the identification of MAO inhibitors from the fruit of P. longum. Activity-guided fractionation of a methylene chloride soluble extract led to the isolation of three known piperine-related compounds… 
Synthesis and inhibitory effect of piperine derivates on monoamine oxidase.
Isolation and Characterization of Acetylcholinesterase Inhibitors from Piper longum and Binding Mode Predictions.
TLDR
The aim of this study was to identify the contained acetylcholinesterase inhibitors of Piper longum using a bioassay-guided phytochemical investigation and to investigate the binding mode of the tested compounds.
Natural based piperine derivatives as potent monoamine oxidase inhibitors: an in silico ADMET analysis and molecular docking studies
TLDR
Piperine related derivatives are found as considerable MAO inhibitors and antioxidants and the SAR structure activity relationships are depicting the structural features required for the MAO inhibition.
Selective MAO-B inhibitors: a lesson from natural products
TLDR
This review presents the latest discoveries in the search for selective MAO-B inhibitors from natural sources and classified compounds on the basis of structural analogy or source: flavonoids, xanthones, tannins, proanthocyanidins, iridoid glucosides, curcumin, alkaloids, cannabinoids, and natural sources extracts.
New amide alkaloids from Piper longum fruits
TLDR
Three new amide alkaloids piperlongumamides A-C, together with 12 known ones, were isolated from the fruits of Piper longum using spectroscopic data analyses, and exhibited weak inhibitory activity against HL-60, A-549, and MCF-7 cell lines.
New Amides and Phenylpropanoid Glucosides from the Fruits of Piper retrofractum
Two new amides (E)-N-cinnamoyl-2-methoxypiperidine (1) and (R)-1-(2-oxopyrrolidin-3-yl)-5,6-dihydropyridin-2(1H)-one (2), four new amide glucosides, retrofractosides A–D (3–6), and two new

Piperine from the fruits of Piper longum with inhibitory effect on monoamine oxidase and antidepressant-like activity.
TLDR
The results suggest that piperine possesses potent antidepressant-like properties that are mediated in part through the inhibition of MAO activity, and therefore represent a promising pharmacotherapeutic candidate as an antidepressant agent.
A review of the mechanisms and role of monoamine oxidase inhibitors in Parkinson’s disease
TLDR
The presence of MAO-A andMAO-B in postmortem human brains suggested the possibility of developing MAO inhibitors directed at each subtype for the treatment of diseases such as PD and depression.

TLDR
MAO A and B knock-out mice are valuable models for investigating the role of monoamines in psychoses and neurodegenerative and stress-related disorders and show increased reactivity to stress.
Piperlonguminine from Piper longum with inhibitory effects on alpha-melanocyte-stimulating hormone-induced melanogenesis in melanoma B16 cells.
TLDR
Piper longum L (fruits, Piperaceae) was discovered to have an inhibitory effect on alpha-melanocyte-stimulating hormone (alpha-MSH)-induced melanogenesis in melanoma B16 cells, and piperlonguminine has been identified as the melanogenesis inhibitor from P. longum by activity-guided extraction and isolation.

Guineensine, an Acyl-CoA: cholesterol acyltransferase inhibitor, from the fruits of Piper longum.
TLDR
Bioactivity-guided fractionations for ACAT inhibitor led to the isolation of guineensine from the CHCl (3) extract of Piper longum, which inhibited ACAT activity in a dose-dependent manner.

TLDR
Piperine showed a lower hepatoprotective potency than silymarin, but exerted a significant protection against tert-butyl hydroperoxide and carbon tetrachloride hepatotoxicity by reducing both in vitro and in vivo lipid peroxidation, enzymatic leakage of GPT and AP.
