Description:

WARNING: This product is for research use only, not for human or veterinary use.

Talfirastide, also known as TXA127 or Angiotensin (1-7), is a synthetic heptapeptide identical to endogenous angiotensin-(1-7) with vasodilator and antiproliferative activities. Therapeutic angiotensin 1-7 may inhibit cyclooxygenase 2 (COX-2) and the production of proinflammatory prostaglandins and may activate the angiotensin-(1-7) receptor Mas, resulting in diminished tumor cell proliferation. Activation of the angiotensin-(1-7) receptor Mas, a G-protein coupled, seven transmembrane protein, may down-regulate the phophorylation and activation of Erk1 and Erk2 in the Erk1/Erk2 Mapk signaling pathway.
