製品説明

Phentolamine mesylate (Phentolamine methanesulfonate) is a reversible, non-selective, and orally active blocker of α1 and α2 adrenergic receptor that expands blood vessels to reduce peripheral vascular resistance. Phentolamine mesylate can be used for the research of pheochromocytoma-related hypertension, heart failure and erectile dysfunction[1][2][3].

体外実験

Phentolamine (0.1-1 μM) inhibits the response to Clonidine in rat ileum, with the pA2 and pKB of 7.92 and 8.07, respectively[3].
? Phentolamine (10-70 μg/mL; 48 h) inhibits proliferation of HDMECs and HBMECs in a dose-dependent manner, with IC50s of 50 μg/mL and 30 μg/mL without toxicity, respectively[4].
? Phentolamine (10-20 or 20-40 μg/mL; 12-48 h) signi?cantly delays scratch wound closure of HBMECs and HDMECs in a dose-dependent manner[4].
? Phentolamine (30 or 50 μg/mL; 4-12 h) inhibits tube formation of HBMECs and HDMECs[4].

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% Corn Oil

    Solubility: ≥ 2.5 mg/mL (6.62 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

For the following dissolution methods, please prepare the working solution directly. It is recommended to prepare fresh solutions and use them promptly within a short period of time.
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:  PBS

    Solubility: 100 mg/mL (264.93 mM); Clear solution; Need ultrasonic

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.
