3.4.21.92 (4R)-3-(4-methoxyphenyl)-4-(pent-4-yn-1-yl)oxetan-2-one inhibitor efficiently alters the oligomerization of the enzyme to smaller species, almost quantitative shift from the tetradecamer to the heptamer with modification of 35% of the active sites 199410 3.4.21.92 1-(1,1-dioxido-1,2-thiazetidin-2-yl)hexan-1-one alkyne-free beta-sultam analogue. Treatment leads to dehydroalanine formation of the active site serine. The reaction proceeds through sulfonylation and subsequent elimination, thereby obliterating the catalytic charge relay system 199414 3.4.21.92 1-(4-benzoyl-1,1-dioxido-1,2-thiazetidin-2-yl)ethanone alkyne-free beta-sultam analogue. Treatment leads to dehydroalanine formation of the active site serine. The reaction proceeds through sulfonylation and subsequent elimination, thereby obliterating the catalytic charge relay system 199412 3.4.21.92 1-[4-(4-ethynylbenzoyl)-1,1-dioxido-1,2-thiazetidin-2-yl]ethanone treatment results in almost instant covalent modification of all 14 active sites and complete inhibition of peptidase activity 199411 3.4.21.92 1-[4-(4-ethynylbenzoyl)-1,1-dioxido-1,2-thiazetidin-2-yl]undec-10-en-1-one inhibitor efficiently alters the oligomerization of the enzyme to smaller species, almost quantitative shift from the tetradecamer to the heptamer with modification of 63% of the active sites 199409 3.4.21.92 1-[4-benzoyl-1,1-dioxido-1,2-thiazetidin-2-yl]undec-10-en-1-one alkyne-free beta-sultam analogue. Treatment leads to dehydroalanine formation of the active site serine. The reaction proceeds through sulfonylation and subsequent elimination, thereby obliterating the catalytic charge relay system 199413 3.4.21.92 3-(4-methoxyphenyl)-4-(pent-4-ynyl)oxetan-2-one shows stronger inhibitory effect 73175 3.4.21.92 3-(non-8-ynyl)-4-(pent-4-ynyl)oxetan-2-one exerts the weakest effect on peptidase activity 73181 3.4.21.92 3-butyl-4-(pent-4-ynyl)oxetan-2-one shows stronger inhibitory effect 73190 3.4.21.92 CAANDENYALAA - 141886
