AA41612
Based on 1 Customer Validation
AA41612 is a melanopsin (Opn4) inhibitor with an IC50 of 15.8 nM, a Ki of 0.43 nM, and a Kd of 0.28 nM. AA41612 competes with retinal for binding to melanopsin, blocks melanopsin activation, and inhibits melanopsin-mediated phototransduction processes without affecting rod- and cone-mediated responses. AA41612 attenuates light-induced melanopsin photocurrents, reduces light-induced cytoplasmic calcium elevation, and weakens high-irradiance pupillary light reflex in mice with induced classical photoreceptor degeneration. AA41612 can be used in studies related to migraine and photophobia.

Animal Model:C57BL/6J (adult, 8-12 weeks, pharmacologically induced classical photoreceptor degeneration via MNU and NaIO3 injection)[2]
-
Dosage:10 mg/kg
-
Administration:i.p.; single dose
-
Result:Reduced pupillary light reflex (PLR) at high irradiances (> 103 μW/cm2) by < 15% at the highest tested irradiance (2.8×104 μW/cm2).
Showed a significant difference between groups via two-way ANOVA with repeated measures.
Confirmed significantly lower PLR at irradiances > 103 μW/cm2 compared to mice injected with only MNU and NaIO3 via post-hoc testing.
