Z-Asp-CH2-DCB
Based on 1 Customer Validation
Z-Asp-CH2-DCB is an irreversible broad spectrum caspase inhibitor. Z-Asp-CH2-DCB also inhibits proteases with caspase-like activity. Z-D-CH2-DCB blocks the production of IL-1β, TNF-α, IL-6, and IFN-γ in staphylococcal enterotoxin B (SEB)-stimulated peripheral blood mononuclear cells (PBMC), and reduces SEB-1-stimulated T-cell proliferation in a dose-dependent manner. Z-Asp-CH2-DCB prevents SU5416-induced septal cell apoptosis and emphysema development.

Biological Activity
Z-Asp-CH2-DCB (10-100 μM) blocks the production of IL-1β, TNF-α, IL-6, and IFN-γ in SEB-stimulated (200 ng; 16 hours) PBMC in a dose-dependent manner. The production of the chemokines MCP-1, MIP-1α, and MIP-1β was also suppresses. The inhibitory effect of Z-Asp-CH2-DCB on TSST-1-activated PBMC is similar, reducing IL-1β, IL-6, TNF-α, IFN-γ, MCP-1, MIP-1α, and MIP-1β to 10, 36, 25, 10, 11, 25, and 30%, respectively, of levels in untreated cells[1].
Z-Asp-CH2-DCB (10-100 μM; 48 hours) inhibits T-cell proliferation in PBMC stimulated with 200 ng of SEB/ml [1].

-
Animal Model:Male Sprague-Dawley rats (SU5416+ Z-Asp-CH2-DCB group)[1]
-
Dosage:1 mg
-
Administration:Intraperitoneal injection; every day for 3 weeks
-
Result:The caspase 3-like activity in SU5416-treated rat lungs is significantly higher, whereas lungs from rats treated with SU5416+Z-Asp-CH2-DCB showed no increase in apoptotic activity.

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.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.08 mg/mL (4.58 mM); Clear solution
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 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.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.08 mg/mL (4.58 mM); Clear solution
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 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.
