  • Title: Simple phosphonic inhibitors of human neutrophil elastase.
    Author: Sieńczyk M, Winiarski Ł, Kasperkiewicz P, Psurski M, Wietrzyk J, Oleksyszyn J.
    Journal: Bioorg Med Chem Lett; 2011 Mar 01; 21(5):1310-4. PubMed ID: 21315589.
    Abstract:
    Herein, we describe the synthesis and resulting activity of a complex series of α-aminophosphonate diaryl esters as irreversible human neutrophil elastase inhibitors and their selectivity preference for human neutrophil elastase over several other serine proteases such as porcine pancreatic elastase, trypsin, and chymotrypsin. We synthesized and examined the inhibitory potency of several new simple Cbz-protected α-aminoalkylphosphonate diaryl esters that yielded several new HNE inhibitors, where one of the obtained compounds Cbz-Val(P)(OC(6)H(4)-4-COOMe)(2) displayed an apparent second-order inhibition value at 33,015 M(-1) s(-1).
