Ucf-101 is a selective and competitive inhibitor of pro-apoptotic protease Omi/HtrA2, with an IC50 of 9.5 μM for His-Omi. Ucf-101 exhibits very little activity against various other serine proteases (IC50>200 μM). Ucf-101 has a natural red fluorescence at 543 nm that is used to monitor its ability to enter mammalian cells. Ucf-101 has a significant cardioprotective effect against MI/R injury and also has certain neuroprotective effect.

Description

Ucf-101 is a selective and competitive inhibitor of pro-apoptotic protease Omi/HtrA2, with an IC50 of 9.5 μM for His-Omi. Ucf-101 exhibits very little activity against various other serine proteases (IC50>200 μM). Ucf-101 has a natural red fluorescence at 543 nm that is used to monitor its ability to enter mammalian cells. Ucf-101 has a significant cardioprotective effect against MI/R injury and also has certain neuroprotective effect[1][2][3].

IC50 & Target

IC50: 9.5 μM (His-Omi)[1]
In Vitro

Ucf-101 (20-100 μM; 30 min) inhibits the proteolytic activity of MBP-Omi-(134-458)[1].
Ucf-101 (10-100 μM; pretreated for 10 min) inhibits His-Omi-(134-458) activity in a concentration-dependent manner when assayed with His-Omi-(134-458) and β-casein[1].
Ucf-101 (1-25 μM; 36 h) inhibits Omi-induced caspase-independent apoptosis of mouse embryo caspase-9 (-/-) null fibroblasts[1].
Ucf-101 (1-20 μM; pretreated for 1 h) inhibits the 6-OHDA-induced apoptosis of Parkinson’s disease (PD)-PC12 cells at the low concentration (2.5 μM), and increases the apoptosis rate at the high concentration (≥10 μM)[3].
Ucf-101 (2.5 μM; pretreated for 1 h) downregulates the expression of Glucose-regulated protein 78 (Bip/Grp78) and C/EBP homologous protein (CHOP) in PD- PC12 cells[3].

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: 1.79 mg/mL (3.61 mM); Suspended solution; Need ultrasonic

    This protocol yields a suspended solution of 1.79 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (17.9 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: 1.67 mg/mL (3.37 mM); Suspended solution; Need ultrasonic

    This protocol yields a suspended solution of 1.67 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (16.7 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

    Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
