Tissue degradation and invasion are hallmarks of the metastatic phenotype. While several extracellular matrix components can be digested by proteases, degradation of interstitial collagen is selectively initiated by collagenase. It is obvious that inhibitors of collagenase activity would be extremely useful in preventing tissue destruction and tumor cell invasion and thus prove invaluable therapeutic agents. We describe here the possible development of such inhibitors through the use of the principle of complementary hydropathy. A peptide was deduced from the nucleotide sequence complementary to that coding for the region in interstitial collagen surrounding the bond between Gly775 and Ile776 which is cleaved by the enzyme. Labeled collagen binds specifically and quantitatively to this peptide. A polyclonal mouse serum raised against this peptide recognized purified human collagenase, was able to immunoprecipitate collagenase from cultured human keratinocyte supernatants and was effective in inhibiting collagenolytic activity with a K(iapp) = 0.3 microM.
