概述
3-氨基丙烷磺酸是一种用于治疗AD的有前途的候选产品。目前在北美和欧洲处于Ⅲ期临床试验阶段。临床试验结果已经被发表。3-氨基丙烷磺酸被公认为能够通过其与可溶性Aβ肽的结合作用,从而减少淀粉样蛋白在脑中的聚集,沉积和/或负载。
应用
3-氨基丙烷磺酸的这种代谢过程对其药代动力学概况及其药物功效具有显着影响。为了提高3-氨基丙烷磺酸的治疗效果,提高其总体的生物可利用度,例如提高稳定性或减缓代谢,一个有效的途径是制成3-氨基丙烷磺酸的前药或衍生物,使其在给予受治疗者后在其体内产生3-氨基丙烷磺酸。
生物活性
Tramiprosate (Homotaurine),一种具有口服活性和可透过血脑屏障的天然氨基酸,存在于各种红色海藻中。Tramiprosate 与可溶性 Aβ 结合并以非原纤维形式维持 Aβ。Tramiprosate 还是一种 GABA 类似物,具有神经保护,抗惊厥和抗高血压的作用。
靶点
Target Value
GABA receptor

体外研究
Tramiprosate (200 μg/mL, 40 μg/mL, 8 μg/mL and 1.6 μg/mL; 1 hours) significantly attenuates oxygen/glucose deprivation (OGD)- or NMDA-induced injury in NGF-differentiated PC12 cells and primary cortical neurons. Tramiprosate decreases the intensity of the association between nNOS and PSD95, and Tramiprosate also inhibits the translocation of nNOS from the cytosol to the membrane.
体内研究
Tramiprosate (6.25-50 mg/kg; intraperitoneal injection; once) treatment dose-dependently reduces the infarct volume after MCAO. Tramiprosate (50 mg/kg) treatment shows a significant neurological functional recovery.
