BER-5
Based on 1 Customer Validation
BER-5 is a potent MrgX2 antagonist. BER-5 possess broad-spectrum antagonistic activity against a diverse range of MrgX2 agonists. BER-5 can inhibit Substance P (SP) (HY-P0201)-induced degranulation of LAD2 cells. BER-5 attenuates SP-induced allergic reactions in mice. BER-5 can be used for the study of allergic reactions.

Biological Activity
BER-5 (12.5-50 μM) inhibits SP-induced degranulation of LAD2 cells specifically manifested by the suppression of β-hexosaminidase (30 min), histamine (2 h), and IL-8 release (6 h)[1].
BER-5 (0-100 μM ,30 min) (IC50 = 20.64 μM) inhibit the SP-induced release of β-hexosaminidase more effectively in LAD2 cells compared with Bergaptol (BER; HY-76316) (IC50 = 46.79 μM) and Imperatorin (IMP; HY-N0285) (IC50 = 99.73 μM)[1].
BER-5 (50 μM) slightly increased the half-maximal effective concentration (EC50) while significantly decreasing the maximum efficiency (Emax) response of SP in LAD2 cells[1].
BER-5 (12.5-50 μM) inhibits degranulation induced by C48/80 (HY-130592), (R)-ZINC-3573 (HY-118069), Rocuronium Bromide (HY-17440) and Ciprofloxacin (HY-B0356) in LAD2 cells, suggesting that BER-5 possess broad-spectrum antagonistic activity against a diverse range of MrgX2 agonists[1].
BER-5 (12.5-50 μM, 30 min) inhibits Ca2+ mobilization induced by SP in a concentration-dependent manner in MrgX2-HEK293 cells[1].

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: ≥ 5 mg/mL (15.61 mM); Clear solution
This protocol yields a clear solution of ≥ 5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (50.0 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: ≥ 5 mg/mL (15.61 mM); Suspended solution
This protocol yields a suspended solution of ≥ 5 mg/mL (saturation unknown). Suspended solution can be used for oral and intraperitoneal injection.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (50.0 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.
