H052
Based on 1 Customer Validation
H052 is a potent Staphylococcus aureus α-hemolysin (Hla) inhibitor. H052 specifically binds to the W286 residue of the Hla monomer, preventing its oligomerization into a heptameric transmembrane pore, thereby completely blocking calcium ion influx and subsequent cell damage and barrier disruption. H052 can be used for research on pulmonary infections caused by S. aureus.

体外実験
H052 (90 nM) inhibits Hla-induced Ca2+ influx in human CD14+ monocytes with EC50 90 nM[1].
H052 (0.04 mM for Hla-induced LDH release; 100 μM for standard cytotoxicity; 72 h) prevents Hla-induced LDH release in A549 cells and is not cytotoxic up to 100 μM[1].
H052 (7.3 mM) protects human airway epithelial cells from Hla-induced cell death in a live-dead assay with EC50 7.3 mM[1].
H052 (4.0 mM) completely protects Calu-3 epithelial barrier integrity from Hla-induced TEER loss at 4.0 mM[1].
H052 (1.6 μM) prevents Hla-induced adherens junction degradation in HPMEC at 1.6 μM[1].
H052 directly binds Hla at W286 to inhibit functional pore formation in biochemical/cell-free assays[2].
H052 protects epithelial and endothelial cells along with erythrocytes and immune cells from Hla-induced damage and covers 79% of published Hla isolates[2].

体内:
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: ≥ 2.5 mg/mL (5.44 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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: ≥ 2.5 mg/mL (5.44 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
