Dh. Kinder et al., ANTIMETASTATIC ACTIVITY OF BORO-AMINO ACID ANALOG PROTEASE INHIBITORSAGAINST B16BL6 MELANOMA INVIVO, Invasion & metastasis, 12(5-6), 1992, pp. 309-319
Di- and tripeptide boro-amino acid analog protease inhibitors with spe
cificity for chymotrypsin and elastase decrease the number of melanoti
c foci formed in the lungs of mice in the B16BL6 experimental metastat
ic tumor model. These effects were at significantly lower concentratio
n than leupeptin or other natural chymotrypsin inhibitors previously r
eported. These results support the involvement of elastase and chymotr
ypsin in the metastatic process.
