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.

Marcfortine A is an indole alkaloid isolated from Aspergillus and Pencillium species.

Marcfortine A is an indole alkaloid, isolated from Aspergillus and Pencillium species, with potent nematocidal activity. The marcfortines are structurally related to paraherquamides and are thought to act by blocking cholinergic neuromuscular transmission.
