Background:

Ivermectin (MK-933) is a broad-spectrum anti-parasite medication used in humans most commonly to treat nematode infections such as onchocerciasis, as well as scabies and lice. Ivermectin (MK-933) is a specific inhibitor of Impα/β1-mediated nuclear import and has potent antiviral activity towards both HIV-1 and dengue virus. It is a positive allosteric effector of P2X4 and the α7 neuronal nicotinic acetylcholine receptor (nAChRs).


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 P2X4 channel 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 P2X4 channels[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].
