Intracellular inhibition of human neutrophil elastase by orally active pyrrolidine-trans-lactams

Bioorg Med Chem Lett. 2001 Jan 22;11(2):243-6. doi: 10.1016/s0960-894x(00)00632-6.

Abstract

Described are the acylation binding of trans-lactam 1 to porcine pancreatic elastase, the selection of the SO2Me activating group for the lactam N which also confers metabolic stability in hamster liver microsomes, the introduction of aqueous solubility through the piperidine salt 9, the in vivo oral activity of 9 and its bioavailability, and the introduction of 9 as an intracellular neutrophil elastase inhibitor.
