产品描述

Ractopamine-d3is intended for use as an internal standard for the quantification of ractopamine by GC- or LC-MS. Ractopamine is a trace amine-associated receptor 1 (TAAR1) agonist.1It increases chloride conductance inX. laevisoocytes expressing the human cystic fibrosis transmembrane conductance regulator (CFTR) and mouse TAAR1 (EC50= 16 µM), an effect that can be blocked by the TAAR1 antagonist EPPTB . It selectively induces chloride conductance in TAAR1- and CFTR-expressing oocytes over those expressing the human β2-adrenergic receptor (β2-AR) and CFTR at 36 µM. However, it is also considered a β2-AR agonist that binds to β2-ARs (Ki= 0.18 µM for the recombinant human receptor expressed in Sf9 cells) and induces relaxation of isolated guinea pig trachea with an EC50value of 9.1 nM.2Formulations containing ractopamine have been used as food additives in livestock to increase weight gain and leanness and improve feed efficiency.
