Biological activity: 1) Lactacystin inhibits cell cycle progression and induces neurite outgrowth in Neuro 2a cells. 2) Inhibits proteasome activity. Proteasome exhibits three protease activities of the tree, Lactacystin inhibits chymotrypsin-like activity most potently, followed by trypsin-like activity, but its inhibitory activity against peptidylglutamylpeptide hydrolytic activity is relatively weak.
