    • Peptide-based compounds including heteroatom-containing, three-membered rings efficiently and selectively inhibit specific activities of N-terminal nucleophile (Ntn) hydrolases. The activities of those Ntn having multiple activities can be differentially inhibited by the compounds described. For example, the chymotrypsin-like activity of the 20S proteasome may be selectively inhibited with the inventive compounds. The peptide-based compounds include an epoxide or aziridine, and functionalization at the N-terminus. Among other therapeutic utilities, the peptide-based compounds are expected to display anti-inflammatory properties and inhibition of cell proliferation.
    • 包括含杂原子的三元环的基于肽的化合物有效地选择性地抑制N末端亲核试剂(Ntn)水解酶的比活性。 具有多种活性的那些Ntn的活性可被所描述的化合物差别地抑制。 例如,本发明化合物可以选择性地抑制20S蛋白酶体的胰凝乳蛋白酶样活性。 肽类化合物包括环氧化物或氮丙啶,并且在N-末端官能化。 除了其他治疗用途之外,预期基于肽的化合物显示抗炎性质和抑制细胞增殖。
