Antipain 

Antipain is a protease inhibitor isolated from Actinomycetes. Antipain inhibits N-methyl-N'-nitro-N-nitrosoguanidine (MNNG)-induced transformation and increases chromosomal aberrations. Antipain restricts uterine DNA synthesis and function in mice^[1][2][3][4].

The intact, cycling female mice received subcutaneous injections of Antipain (3 mg) for 16 days, their uteri shows significant diminution in weight and total DNA when compared to untreated controls^[4].
Antipain (100 μg/g body wt; i.p.; at 12h intervals from 0 to 120 h or 240 to 360 h) shows inhibitory effect on Urethane-induced lung neoplasia in mice^[5].
