Description

Icatibant (HOE-140) is a potent and specific peptide antagonist of bradykinin B2 receptor with IC50 and Ki of 1.07 nM and 0.798 nM respectively[1][2][3].

IC50 & Target

Bradykinin B2 Receptor (B2R)

 

In Vitro

Icatibant (10-30 μM) potentiates angiotensin III, but not angiotensin II (contraction mediated by angiotensin AT1 receptors), and Lys-des-Arg9-bradykinin, but not des-Arg9-bradykinin (effects mediated by the bradykinin B1 receptors)[3].

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

In Vivo

Icatibant (0.3, or 1.5 mg/kg, subcutaneous administration twice daily in mice) shows a significant preventive effect on ulcerative Colitis[2].

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

Animal Model: Female mice of the CBA/J (H-2k) strain[2].
Dosage: 0.06, 0.3, or 1.5 mg/kg.
Administration: Subcutaneous administration twice daily.
Result: The length of the large intestine was 93.6±6.8 mm with the 1.5 mg/kg dosage and 94.0±4.1 mm with the 0.3 mg/kg dosage , showing a significant preventive effect on shortening.

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.
