MK3102 (Omarigliptin) is a novel once-weekly dipeptidyl peptidase-4 (DPP-4) inhibitor (IC50: 2.2 nM) developed for the treatment of type 2 diabetes [1,2]. MK3102 crossed the blood brain barrier (BBB) due to its low molecular weight and lipophilic properties [3].
MK3102 (3, 10, 30, and 50 µM, 4 h) pretreated PC12 cells were attenuated 6-OHDA (50 µM, 24h) - or rotenone (1 µM, 24h) - induced cytotoxicity. MK3102 inhibited the 6-OHDA- or rotenone-induced production of intracellular ROS in PC12 cells [4]. MK3102 decreased the 6-OHDA- and rotenone-induced IκBα phosphorylation and nuclear translocation of NF-κB, resulting in reduced production of the inflammatory mediator NO and iNOS expression [4]. MK3102 suppressed the release of HMGB-1, and decreased the permeability of endothelial monolayer in bEnd.3 brain endothelial cells [1].
MK3102 has a long half-life (rat, 11 h; dog, 22 h) and lower clearance (rat, 1.1 mL min-1 kg-1; dog, 0.9 mL min-1 kg-1) in preclinical species [5]. Concentration of MK3102 in rats' plasma (5 mg/kg, after 2 h, p.o) were found to be 2688.79 ng/mL, MK3102 crossed the BBB after the oral administration showing concentration of 621.75 ng/g in brain tissue. Intra-nasal administration of OG showed significant higher brain/plasma concentration ratio of 0.76 enhancing the ratio by 3.3 folds compared to the oral route [3]. MK3102 (5 mg/kg/d) suppressed the release of inflammatory factors in the brains of LPS-Stimulated mice and protected the BBB integrity destroyed by LPS stimulation [1].
