Bioactivity | Monomethyl fumarate, an active metabolite of Dimethyl fumarate (DMF), is a potent GPR109A agonist. Monomethyl fumarate has the potential for multiple neuroprotective pathways and other models of retinal disease[1][2][3]. | ||||||||||||
Invitro | Monomethyl fumarate completely inhibits forskolin induced cAMP synthesis with an IC50 of 70 nM. Monomethyl fumarate induces a dose-dependent Ca2+ signal in GPR109A transfected cells with an EC50 of 9.4 μM[1]. Monomethyl fumarate (25 μM; 24 hours) attenuates 7β-OHC-induced cytotoxicity: cell growth inhibition; decreased cell viability; mitochondrial dysfunction; and cell death induction[3]. | ||||||||||||
In Vivo | A single dose of Monomethyl fumarate (50-100 mg/kg; IP) before light exposure prevents these morphologic changes (bright light exposure induced photoreceptor death) in a dose-dependent manner[2]. Monomethyl fumarate (100 mg/kg) reduces retinal inflammation and oxidative stress. Monomethyl fumarate significantly suppresses light-induced retinopathy (LIR) upregulated genes in the NFkB pathway including: Nlrp3, Casp1, Il-1β, and Tnf-α[2]. Animal Model: | ||||||||||||
