Ivermectin (MK-933) is a broad-spectrum anti-parasite agent. Ivermectin (MK-933) is a specific inhibitor ofImpα/β1-mediated nuclear importand has potent antiviral activity towards bothHIV-1and dengue virus. It is a positive allosteric effector ofP2X₄and the α7 neuronal nicotinic acetylcholine receptor (nAChRs). Ivermectin also inhibitsbovine herpesvirus1 (BoHV-1)replication and inhibitsBoHV-1DNA polymerase nuclear import^[1][2][3][4]. Ivermectin is a candidate therapeutic againstSARS-CoV-2/COVID-19^[5].

In the submicromolar range (EC₅₀=250 nM) the action of Ivermectin (MK-933) is rapid and reversible, resulting in increased amplitude and slowed deactivation of P2X₄channel currents evoked by ATP^[1].
Ivermectin (MK-933) markedly increases the potency of ATP and that of the normally low-potency agonist a,b-methylene-ATP in a use- and voltage-independent manner without changing the ion selectivity of P2X₄channels^[1].
Ivermectin (MK-933) activates glutamate-gated chloride channels in the nerves and muscles of the parasite, leading to membrane hyperpolarization and muscle paralysis^[2].
Ivermectin (MK-933) strongly inhibits the binding of Impα/β1 to NS5 (IC₅₀=17 μM), but not of Impβ1 alone to NS5^[3].
Ivermectin (MK-933) has potent antiviral activity towards both HIV-1 and dengue virus, both of which are strongly reliant on importin α/β nuclear import, with respect to the HIV-1 integrase and NS5 (non-structural protein 5) polymerase proteins respectively^[3].
