A direct rate assay for plasminogen activator has been developed using a synthetic fluorogenic peptide substrate, 7-(N-Cbz-glycylglycylargininamido)-4-methylcoumarin trifluoroacetate, which should be useful for the study of the effect of various agents on functional changes in cells secreting this enzyme.

It is reported that neutral cephalosporins (that is, compounds not bearing a free carboxyl at position C-4) can be modified to become potent time-dependent inhibitors of HLE.

While the most potent in vitro HLE inhibition had previously been obtained with lipophilic ester derivatives, it was found that the less active, but more polar and stable, amide derivatives were much more effective in vivo.

A failure to maintain normal levels of elastase and cathepsin G in mature PMNs in the beige mousezo has been described which may be due to inactivation of enzyme by inhibitors present.
