Structure–activity studies of cyclic ketone inhibitors of the serine protease plasmin: Design, synthesis, and biological activity
摘要:
Three series of cyclic ketone inhibitors were synthesized and evaluated against the serine protease plasmin. Peptide inhibitors that incorporated 3-oxotetrahydrofuran and 3-oxotetrahydrothiophene 1,1-dioxide groups had the highest activities. Alkylamino substituents, which were designed to bind in the S1 subsite of plasmin, were attached to the inhibitors. Compounds 5c and 5g, which incorporated 6-aminohexyl substituents, were found to be optimal and demonstrated IC50 values in the low micromolar range. Incorporating conformationally constrained peptide segments into the inhibitors did not improve their activities. (c) 2006 Elsevier Ltd. All rights reserved.
