Biological Activity: Paraherquamide A (PNU-97333) is an anthelmintic and nicotinic acetylcholine receptor (nAChR) antagonist, with pIC50 values ranging from 6.87 to 7.58 for L-type nAChR and from 4.84 to 5.54 for N-type nAChR. Paraherquamide A acts as a competitive antagonist against multiple nematode nAChR subtypes, as well as a mixed competitive-noncompetitive antagonist against nematode N-type nAChR. Paraherquamide A induces flaccid paralysis in parasitic nematodes without altering ATP levels, inhibits nematode motility, and antagonizes cholinergic agonist-induced muscle contraction in nematodes. Paraherquamide A can be used in studies related to nematode parasitic infections[1][2].
