)methylamino]-L-proline, 2-ester with salicyclic acid (14a), and its 1-benzoyl analogue (14b), were designed to bind covalently to beta Lys-132, as well as to interact with beta His-2 and beta Thr-4 via ionic and hydrogen bonds. This paper describes the synthesis of these agents, beginning with natural L-hydroxyproline methyl ester, and the testing of their ability to increase or decrease the solubility

that engages in a hydrogenbond with Gly 216. The first series of inhibitors has a m-chlorobenzyl moiety binding in the S1 pocket, and the second has a benzamidine moiety. When the adjacent hydrogenbond is present, the enhanced binding affinity per Å2 of hydrophobic contact surface in the S3 pocket improves by 75% and 59%, respectively, over the inhibitors lacking this hydrogenbond. This improvement
