體外研究
(In Vitro)

Sitagliptin phosphate 對(duì) Caco-2 細(xì)胞提取物中的 DPP-4 表現(xiàn)出有效的抑制作用,IC50 為 19 nM[1]。西格列汀通過(guò)涉及 cAMP/PKA/Rac1 激活的通路減少分離的脾臟 CD4 T 細(xì)胞的體外遷移[2]。最近的一項(xiàng)研究表明,西格列汀發(fā)揮一種新穎的直接作用,通過(guò) DPP-4 獨(dú)立的、蛋白激酶 A 和 MEK-ERK1/2 依賴的途徑刺激腸道 L 細(xì)胞分泌 GLP-1。因此,它降低了自身免疫對(duì)移植物存活的影響[3]

體內(nèi)研究
(In Vivo)

在自由喂養(yǎng)的 Han-Wistar 體內(nèi),Sitagliptin phosphate 抑制血漿 DPP-4 活性的 ED50 值計(jì)算為給藥后 7 小時(shí) 2.3 mg/kg 和給藥后 24 小時(shí) 30 mg/kg大鼠[1]。
鏈脲佐菌素誘導(dǎo)的 1 型糖尿病小鼠模型顯示血漿中 DPP-4 水平升高,這在服用 Sitagliptin phosphate 飲食的小鼠中可被顯著抑制。這是通過(guò)對(duì)高血糖癥的調(diào)節(jié)產(chǎn)生積極影響來(lái)實(shí)現(xiàn)的,可能是通過(guò)延長(zhǎng)胰島移植物的存活[4]
Sitagliptin phosphate 的血漿清除率和分布容積在大鼠中 (40-48 mL/min/kg,7-9 L/kg) 高于狗 (9 mL/min/kg,3 L/kg);其半衰期在大鼠中較短,為 2 小時(shí),而在狗中為 4 小時(shí)[5]。

Cell Assay
[2]

CD4T-cells are plated on membrane inserts in serum-free RPMI 1640, and cell migration is assayed using Transwell chambers (Corning), in the presence or absence of purified porcine kidney DPP-4 (32.1 units/mg; 100 mU/mL final concentration) and DPP-4 inhibitor (100 μM). After 1 hour, cells on the upper surface are removed mechanically, and cells that have migrated into the lower compartment are counted. The extent of migration is expressed relative to the control sample.

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Administration
[1]

Mice: Overnight fasted C57BL/6J mice are challenged 45 min after compound administration with an oral glucose load (2 g/kg). Blood samples for glucose measurement are obtained by tail bleed predose and at serial time points after the glucose load. To evaluate the duration of the effect on glucose tolerance, vehicle or DPP-4 inhibitors are administered 16 h before the glucose challenge.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
