Marcfortine A NSC 324645	Human Gut Microbiota Metabolites Microorganisms Source classification Endogenous metabolite	Parasite
Marcfortine A is an indole alkaloid originally isolated from P. roqueforti. It has nematocidal activity against the parasitic nematode H. contortus (LD99=0.06 μg/mL) and inhibits motility of adult worms (EC₅₀=2 μM). Marcfortine A eliminates H. contortus, T. colubriformis, and O. ostertagi from experimentally infected jirds (ED95s=0.33, 0.11, and 2.5 mg/animal, respectively). It dose-dependently inhibits nicotine-induced calcium mobilization in SH-SY5Y and TE-671 cells expressing α3 subunit-containing human nicotinic acetylcholine receptors (nAChRs) and muscle-type nAChRs, respectively.

Harmane 1 Publications Verification	Alkaloids Structural Classification other families Source classification Pyridine Alkaloids Plants Indole Alkaloids	Imidazoline Receptor Monoamine Oxidase Adrenergic Receptor nAChR GABA Receptor Opioid Receptor
Harmane is an inhibitor that binds to benzodiazepine receptors (with an IC₅₀ value of 7 μM), has an IC₅₀ of 24 μM for *muscarinic acetylcholine* receptors (QNB), an IC₅₀ of 2.8 μM for opioid receptors, and IC₅₀ values of 163 and 101 μM for spironolactone and serotonin*, respectively. Harmane is a selective monoamine oxidase inhibitor* (with IC₅₀ values of 0.5 μM for MAO A and 5 μM for MAO B). Harman inhibits dopamine biosynthesis by decreasing tyrosine hydroxylase (TH) activity and enhancing levodopa (L-DOPA)-induced toxicity in PC12 cells. Harmane lowers blood pressure in rats through the I1 imidazoline receptor (I1 receptor) and has antidepressant, anxiolytic, anticonvulsant, and analgesic effects. Harmane enhances the mutagenicity induced by 2-acetylaminofluorene (AAF) .

Arecaidine propargyl ester hydrobromide		Alkynes
Arecaidine propargyl ester hydrobromide is an agonist of M2 muscarinic acetylcholine receptors and has the activity of inhibiting tumor cell proliferation. The application of arecaidine propargyl ester hydrobromide has shown that it can reduce the number of ovarian cancer cells in vitro and induce apoptosis and the production of reactive oxygen species (ROS) at specific concentrations. Arecaidine propargyl ester hydrobromide can also arrest cells at the G2/M phase of the cell cycle and increase the percentage of abnormal mitosis. Arecaidine propargyl ester hydrobromide is more sensitizing to ovarian surface epithelial cells with higher M2 receptor levels than to cancer cells. Arecaidine propargyl ester hydrobromide exhibits the effect of lowering arterial blood pressure when interacting with the cardiovascular system in a natural physiological state, indicating its potential pharmacological application .
