ONX-0914 PR-957

产品介绍 ONX-0914 (PR-957) 是选择性的低分子量多肽-7 (LMP7) 的抑制剂,LMP7 是免疫蛋白酶体的类糜蛋白酶亚单位。ONX-0914 阻断细胞因子的产生并减轻实验性关节炎的进展。ONX-0914 是分枝杆菌蛋白酶体的非竞争性不可逆抑制剂 (Ki=5.2 μM)。ONX-0914 通过 HSF-1 介导的 p-TEFb 活化激活潜伏的 HIV-1。
生物活性

ONX-0914 (PR-957) is a selective inhibitor of low-molecular mass polypeptide-7 (LMP7), the chymotrypsin-like subunit of the immunoproteasome. ONX-0914 blocks cytokine production and attenuates progression of experimental arthritis. ONX-0914 is a noncompetitive irreversible inhibitor of the mycobacterial proteasome (Ki=5.2 μM). ONX-0914 reactivates latent HIV-1 through p-TEFb activation mediated by HSF-1.

体外研究

ONX-0914 inhibits LMP7-specific antigen presentation. ONX-0914 blocks cytokine productionby mouse splenocytes and blocks T celldifferentiation.

体内研究

ONX-0914 (2-10 mg/kg; i.v,; on days 4, 6 and 8) meliorates disease in mouse arthritis.
ONX-0914 (2, 6 and 10 mg per kg body weight on days 25, 27, 29, 31 and 33; i.v.) treatment also induced a rapid therapeutic response in the T and B cell–dependent CIA (collagen-induced arthritis) model.

西域 has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Collagen antibody-induced arthritis (CAIA, Arthritis was induced in BALB/c mice with antibodies specific for type II collagen (mAb) and endotoxin)
Dosage: 2, 6 or 10 mg per kg body weight
Administration: I.v.; treated on days 4, 6 and 8
Result: Blocked disease progression in a dose-dependent manner and completely ameliorated visible signs of disease at the highest dose.
