Abstract:
Bowman-Birk inhibitor analogues containing 2, 3 and 4-carbon analogues of the natural disulfide were synthesised via solid phase microwave-assisted RCM and found to have K(i) values against chymotrypsin in the low to sub-micromolar range, the best replacement for the disulfide arising from the linkage by RCM of two l-homoallylglycine residues.
