Description | MTP 131 (acetate) is a small mitochondrially-targeted tetrapeptide. |
In vitro | 细胞预处理MTP 131 (acetate)能够抑制H2O2引起的细胞毒性,并以剂量依赖性方式减少LDH释放,相比仅用H2O2处理的细胞。MTP 131 (acetate)预处理也防止了线粒体去极化和ROS生成。此外,MTP 131 (acetate)预处理抑制了细胞色素c从线粒体释放至细胞质,并显著减少了与仅H2O2处理相比的RGC-5细胞凋亡[1]。 |
In vivo | 18周龄的db/db小鼠,通过二氢乙菲啶氧化测量显示,其肾脏和心脏的超氧化物水平有所下降,同时尿白蛋白水平、系膜基质累积及尿液中H2O2水平有所上升。MTP 131 acetate的施用显著抑制了db/db小鼠中尿白蛋白、尿液H2O2及系膜基质累积的增加,并完全保持了这些小鼠肾脏超氧化物产生的水平。此外,MTP 131 acetate还降低了db/db小鼠总肾脏溶血卡磷脂及其主要亚型水平,并保持了溶血卡磷脂酰基转移酶1的表达[1]。 |
