Peptide-based compounds including heteroatom-containing, three-membered rings efficiently and selectively inhibit specific activities of N-terminal nucleophile (Ntn) hydrolases associated with the proteasome. 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. Oral administration of these peptide-based proteasome inhibitors is possible due to their bioavailability profiles.
肽基化合物包括含杂原子的三元环,能有效并选择性地抑制与蛋白酶体相关的 N-末端亲核(Ntn)水解酶的特定活性。肽基化合物包括环氧化物或氮丙啶,并在 N 端进行了官能化。除其他治疗作用外,肽基化合物还具有抗炎和抑制细胞增殖的作用。由于这些肽基蛋白酶体抑制剂具有生物利用度高的特点,因此可以口服给药。
