AA92593 is a selective and competitive OPN4 (melanopsin) antagonist[1][2].
AA92593 is a competitive melanopsin antagonist, its presence in the retinal-binding pocket of melanopsin leads to the displacement of retinal, which could trigger a downstream signaling that would ultimately result in Per1 increased expression[1].AA92593 is shown to be specific because it competes with retinaldehyde for the melanopsin retinal binding site which is very distinct from other opsins[1].Inhibition of melanopsin activity with AA92593 increases a-MSH expression and induces melanin dispersion in the melanophores, which darkens the embryo[3].AA92593 exhibits an IC50 of 665 nM in CHOOpn4 cells[4].
AA92593 is able to decrease IOP in rabbits living under normal light condition[2].AA92593 produces an increment in melatonin levels resulting in a drop of IOP[2].
