PF 1022A is a cyclooctadepsipeptide with broadspectrum anthelmintic properties produced by fermentation of the fungus Mycelia sterilia. PF 1022A is a channel-forming ionophore. PF 1022A showes strong anthelmintic activities against Ascaridia galli in chickens. PF 1022A also can be used for angiostrongyliasis research .
In Vitro
PF 1022A binds to the latrophilin-like transmembrane receptor important for pharyngeal pumping in nematodes. Furthermore, PF 1022A binds to GABA receptors, which might contribute to the anthelmintic effect. In vitro, PF 1022A shows low activity on embryonation but significantly inhibits egg hatch (10 and 100 μg/mL), whereas albendazole (10 and 100 μg/mL) reveales statistically significant inhibitions of both embryonation and egg hatch. PF 1022A (1-100 μg/mL) completely inhibits larval movement at most examination points. MCE has not independently confirmed the accuracy of these methods. They are for reference only.
