体外研究
Pepstatin A对天冬氨酸蛋白酶比如蛋白质，组织蛋白酶D和E表现出有效的抑制作用。在HIV感染的H9细胞中，pepstatin A抑制部分细胞内HIV gag蛋白质的合成，而对HIV感染的细胞没有显著毒性。 Pepstatin A通过阻断ERK信号并抑制NFATc1的表达抑制破骨细胞的增殖。
体内研究
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.
