Design and synthesis of a novel class of furan-based molecules as potential 20S proteasome inhibitors

A novel class of furan-based compounds as potential 20S proteasome inhibitors have been designed and synthesized, among which nine compounds are peptide derivatives and six molecules are statine peptidomimetics. The C-terminal furanyl moiety was introduced to target molecules as furan-based amino acids. All the compounds were obtained steadily with moderate to high yield. Compound 12 was a selective moderate potent proteasome peptidomimetic inhibitor. It inhibited HepG2 and HL-60 proliferation effectively.

All the compounds were obtained steadily with moderate to high yield. Compound 12 was a selective moderate potent proteasome peptidomimetic inhibitor (IC50 = 7.85 μM, CT-L activity). It inhibited HepG2 and HL-60 proliferation effectively (IC50 = 34.2 and 37.07 μM, respectively).Figure optionsDownload as PowerPoint slide
