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 at least three peptide units, 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.
基于肽的化合物包括含杂原子的三元环,可以高效且选择性地抑制N-末端亲核试剂(Ntn)水解酶的特定活性。所述化合物可以差异性地抑制具有多种活性的Ntn的活性。例如,20S蛋白酶体的胰凝乳样活性可以通过该发明的化合物被选择性地抑制。基于肽的化合物包括至少三个肽单元,环氧或氮杂环以及N-末端的功能化。在其他治疗用途中,基于肽的化合物预计将显示抗炎性和细胞增殖抑制作用。
