Monomethyl fumarate 是 Dimethyl fumarate (DMF) 的活性代谢产物,一种有效的 GPR109A 激动剂。Monomethyl fumarate 具有用于多种神经保护途径和其他视网膜疾病模型的潜力。
生物活性 | Monomethyl fumarate, an active metabolite of Dimethyl fumarate (DMF), is a potentGPR109A agonist. Monomethyl fumarate has the potential for multiple neuroprotective pathways and other models of retinal disease[1][2][3]. |
体外研究 (In Vitro) | Monomethyl fumarate completely inhibits forskolin induced cAMP synthesis with an IC50of 70 nM. Monomethyl fumarate induces a dose-dependent Ca2+signal in GPR109A transfected cells with an EC50of 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].

体内研究 (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: | Albino BALB/c mice (male, 6 weeks old)[2] | Dosage: | 50, 65, 75, 100 mg/kg | Administration: | IP | Result: | Prevented these morphologic changes (bright light exposure induced photoreceptor death) in a dose-dependent manner. |
