Description
Ivermectin B1ais the main component (>80%) of the anthelmintic ivermectin, which also contains ivermectin B1b(<20%; ). It produces antiparasitic activity by binding to glutamate-gated chloride channels expressed on nematode neurons and pharyngeal muscle cells, inducing irreversible channel opening and very long-lasting hyperpolarization/depolarization of the neuron/muscle cell, thereby blocking further function (EC50= 104 nM). Formulations containing ivermectin inhibit replication of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in Vero/hSLAM cells.
ChEBI: A macrocyclic lactone that is avermectin B1a in which the double bond present in the spirocyclic ring system has been reduced to a single bond. It is the major component of ivermectin.
