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]
