Design, synthesis, and biological activity of potent and selective inhibitors of mast cell tryptase

A new series of novel mast cell tryptase inhibitors is reported, which features the use of an indole structure as the hydrophobic substituent on a m-benzylaminepiperidine template. The best members of this series display good in vitro activity and excellent selectivity against other serine proteases. (c) 2005 Elsevier Ltd. All rights reserved.
