产品描述:

产品名称:Q-VD-OPh

靶点: Caspase

CAS号: 1135695-98-5

描述:

Q-VD-OPh is a potent pan-caspase inhibitor with IC₅₀ ranging from 25 to 400 nM for caspases 1, 3, 8, and 9, showing inhibitory effects on terminal caspase activation, substrate cleavage, and DNA ladder formation associated with apoptosis.

英文别名: QVD-OPH;Quinoline-Val-Asp-Difluorophenoxymethylketone

外观: white to light brown powder

In vitro(体外研究): Q-VD-OPh is a potent inhibitor of caspase-7 with an IC₅₀ of 48 nM utilizing a cell-free assay consisting of human recombinant caspase-7, Q-VD-OPh, and the substrate AMC-DEVD-pNa. Q-VD-OPh fully inhibits caspase-3 and -7 activity at 0.05 μM. Caspase-8 is also inhibited at low Q-VD-OPh concentrations. The cleavage of PARP-1 is fully prevented at 10 μM Q-VD-OPh. DNA fragmentation and disruption of the cell membrane functionality are both prevented at 2 μM Q-VD-OPh. Q-VD-OPh is significantly more effective in preventing apoptosis than the widely used inhibitors, ZVAD-fmk and Boc-D-fmk, and is also equally effective in preventing apoptosis mediated by the three major apoptotic pathways, caspase 9/3, caspase 8/10, and caspase12. Q-VD-OPh is not toxic to cells even at extremely high concentrations. QVD is also able to increase the expression of differentiation markers in acute myeloid leukemia (AmL) blasts. QVD alone or combined with VDDs increases differentiation and HPK1-cJun signaling in AmL cell context-dependent manner.

分子式: C₂₆H₂₅F₂N₃O₆

In vivo(体内研究): Chronic treatment with Q-VD-OPh prevents caspase-7 activation and limits the pathological changes associated with tau, including caspase cleavage. Q-VD-OPh could be a potential therapeutic compound for the treatment of Alzheimer's disease.
