Tolazoline(Imidaline) is a non-selective competitive α-adrenergic receptor antagonist.

IC50 & Target


In Vitro

Tolazoline (Imidaline) can be synthesized by the heterocyclation of the ethyl ester of iminophenzylacetic acid with ethylene diamine, which forms the desired product. The structure of Tolazoline (Imidaline) is strikingly similar to α-adrenergic agonists, which are antiedema sympathomimetics.

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

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.

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
