生物活性
Pepstatin A (Pepstatin) 是一種強效的aspartic protease抑制劑, 并可抑制HIV的復(fù)制。Pepstatin A 也是 cathepsins D 和 cathepsins E 的抑制劑。Pepstatin A 通過抑制溶酶體蛋白酶來抑制自噬。靶點

體外研究
Pepstatin A對天冬氨酸蛋白酶比如蛋白質(zhì),組織蛋白酶D和E表現(xiàn)出有效的抑制作用。在HIV感染的H9細胞中,pepstatin A抑制部分細胞內(nèi)HIV gag蛋白質(zhì)的合成,而對HIV感染的細胞沒有顯著毒性。 Pepstatin A通過阻斷ERK信號并抑制NFATc1的表達抑制破骨細胞的增殖。
體內(nèi)研究
Pepstatin (Pepstatin A) has a very low toxicity, with LD 50 s of 1090 mg/kg, 875 mg/kg, 820 mg/kg and 450 mg/kg for mice, rats, rabbits, and dogs by i.p. route, and > 2000 mg/kg for all species by oral route. Pepstatin (0.5-50 mg/kg, p.o.) suppresses stomach ulceration of the pylorus in ligated Shay rats.
