Avermectin A1a, 5-O-demethyl-22,23-dihydro- Chemical Properties,Uses,Production
Description
Ivermectin B1a is 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.
Uses
Ivermectin B1a-D2 is a deuterium labelled analogue of Ivermectin B1a (I940815), which is a major component of Ivermectin (I940800), a semi-synthetic derivative of Abamectin; consists of a mixture of not less than 80% component B1a and not more than 20% component B1b. Antihelmintic (Onchocerca). An invitro inhibitor of SARS-CoV-2/ Covid-19.
Definition
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.
