Three peptides with sequences related to the binding loop of Cucurbita maxima trypsin inhibitor III were obtained: [G3,GIO]CMTI-HI (1-10) (1), [A1,G3,A9,G10]MTlII (1-10) (2) and c(K-A-A-P-R-I-L-M-K-Y-A-E) (3). All peptides were synthesized by the solid-phase methodusing the Fmoc/Bu t procedure. Peptide 1 revealed a relatively high inhibitory activity (association equilibrium constant with bovine beta-trypsin Ka = 4 x 10 9 [M -1]). Significantly lower activity (Ka = 3.6x l O4 [M -1) was obtained for peptide 3. Peptide 2 appeared to be inactive.
