Azeliragon (TTP488) 是一种生物可利用的晚期糖基化终产物 (RAGE) 受体抑制剂,可缓解轻度阿尔茨海默病 (AD) 的发展。Azeliragon 还可穿过血脑屏障 (BBB)。
生物活性 | Azeliragon (TTP488) is an orally bioavailable inhibitor of thereceptor for advanced glycation end products (RAGE)in development as a potential treatment to slow disease progression in patients with mild Alzheimer’s disease (AD)[1]. Azeliragon also can cross the blood-brain barrier (BBB)[2]. |
体外研究 (In Vitro) | Azeliragon (4 nM; 16 hours; T cells) treatment inhibits of wild type mice (WT) but not the deletion of the receptor (RAGE-/- mice) T cells and significant reduction in the production of IFN-γ[3].
Cell Viability Assay[3] Cell Line: | Purified T cells from RAGE-/- or WT B6 mice. | Concentration: | 4 nM | Incubation Time: | 16 hours | Result: | Inhibited of WT but not RAGE-/- T cells, and significantly reduced the level of IFN-γ. |
|
体内研究 (In Vivo) | Azeliragon (100 mcg/d; intraperitoneal injection; every day) treatment reduces syngeneic islet graft and islet allograft in NOD and B6 mice (Islets were isolated from young prediabetic NOD/LtJ mice and transplanted into NOD mice with spontaneous diabetes; islets were isolated from WT BALB/c mice and transplanted into B6 mice with diabetes)[3].
Animal Model: | Prediabetic NOD/LtJ (6-7 week old) mice, NOD mice with spontaneous diabetes, WT BALB/c mice (8-10 week old) and B6 mice with diabetes[3]. | Dosage: | 100 mcg/d | Administration: | Intraperitoneal injection; every day | Result: | Prolonged islet auto and allograft survival. |
