PR-39 TFA 是富含脯氨酸和精氨酸的天然抗菌肽,是一种非竞争性,可逆和变构的蛋白酶体 (proteasome) 抑制剂。PR-39 TFA 可逆地结合到蛋白酶体的 α7 亚基上,并通过泛素-蛋白酶体途径阻断 NF-κB 抑制剂 IκBα 的降解。PR-39 TFA 刺激小鼠的血管生成,抑制炎症反应并显着减小心肌梗死面积。
PR-39 TFA, a natural proline- and arginine-rich antibacterial peptide, is a noncompetitive, reversible and allosteric proteasome inhibitor. PR-39 TFAreversibly binds to the α7 subunit of the proteasome and blocks degradation of NF-κB inhibitor IκBα by the ubiquitin-proteasome pathway. PR-39 TFA stimulates angiogenesis, inhibits inflammatory responses and significant reduces myocardial infarct size in mice[1][2].
