摘要:
A dichlorocyclopropane fused lactone derivative was prepared as a novel mechanism-based inactivator of serine protease, alpha-chymotrypsin. The lactone derivative showed transient irreversible inhibitory activity toward alpha-chymotrypsin with the value of kobsd/[I] = 54 M(-1)s(-1) and the enzyme activity recovered perfectly after 6 hours.
