Cell lines |
PC12 cells |
|
Preparation Method |
PC12 cells were treated with MK3102 at a series of concentrations in culture media containing low serum (1% FBS, 1% HS, 100 IU/mL penicillin, and 100 µg/mL streptomycin) for 24 h. Control cells were treated with the same media containing low serum and an equivalent volume of DMSO (0.5%). The protective effects of MK3102 against 6-OHDA- or rotenone-induced toxicity in PC12 cells were evaluated. Briefly, cells were pretreated with MK3102 at various concentrations for 4 h and subsequently exposed to 6-OHDA (50 µM) or rotenone (1 µM) for 24 h. The effect of ZnPP, an HO-1 inhibitor, on the protective effects of MK3102 against 6-OHDA- or rotenone-induced toxicity was evaluated. In brief, the cells were pretreated with 0.2 µM ZnPP for 30 min and exposed to MK3102 for 4 h. Then, 6-OHDA or rotenone was added at the final concentrations of 50 and 1 µM, respectively, and incubated for 24 h. |
|
Reaction Conditions |
0-100µM for 24 hours; 0-50µM pretreat for 4 hours |
|
Applications |
Pretreatment with MK3102 presented a significant reversal of the 6-OHDA-induced toxicity at concentrations of 30 and 50 µM. |
| Animal experiment [2]: | |
|
Animal models |
Male C57BL/6 mice |
|
Preparation Method |
The 24 mice (6- to 8-week-old) were divided into 4 groups: the vehicle, MK3102, LPS, and LPS + MK3102 groups. The animals were orally administered with either vehicle (saline) or MK3102 at 5 mg/kg/d for 15 days. On the last day, the animals in the LPS and the LPS + MK3102 groups were intraperitoneally injected with LPS (5 mg/kg). The control and the MK3102 groups were intraperitoneally injected with the same amounts of saline. |
|
Dosage form |
5 mg/kg/d, oral, for 15 days. |
|
Applications |
Compared with the vehicle group, the expression levels of TNF-α, IL-6, and IL-8 were elevated significantly in the brain of LPS stimulated mice but were greatly suppressed by the coadministration of MK3102. |

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].
