Abstract

The mode of action of known natu,ral and syritheti􀀔 inhibitors of the serine _ protease trypsin was studied using struc􀀝e-based drug design: Three groups of putative . . inhibitors were examined. Group I inhibitors consist of molecules designed to incorporate the binding properties of a natural inhibit􀀭r. Group 11 inhibitors wern . . . constructed from a combination of a· hydrophobic tetrapeptide and a hydrophilic di peptide, and Group III were cyclic phenylthiohydru1toin deriv􀀼tives: As a result of the study of the interactioris between certain residri􀁈􀁉 or.features of the inhibitor m􀀅lecule,

such as hydrophobic appendages . or cyclic conformation, .. and specific .· binding sites . on the surface of the enzyme, the_ ma1n features of binding of the serine proteases were delineated Relative binding eilergi􀁟s obtained fr􀁠m moJecular modeling and computational chemistry show that _many of th_e de􀁧igned 1nhibitors exhibit fav9rable . binding. One lead compound, a phenylthiohydantoin- arginine • was shown 􀁲y fluoresc􀁴nt _­ assay.to inhibit Bovine trypsin.
