Pepstatin A (Pepstatin) is a specific inhibitor of aspartic proteases produced by actinomycetes, which can inhibit hemoglobin-pepsin, hemoglobin-proctase, casein-pepsin, casein-proctase, casein-acid protease and hemoglobin-acid protease with IC50 values of 4.5 nM, 6.2 nM, 150 nM, 290 nM, 520 nM and 260 nM, respectively. Pepstatin also inhibits HIV protease.
