RTI-7470-44 is a highly potent and selective antagonist of the human trace amine-associated receptor 1 (hTAAR1), demonstrating an IC50 of 8.4 nM in an in vitro cAMP functional assay. In radioligand binding studies, it exhibits a Ki value of 0.3 nM, highlighting its strong affinity for hTAAR1. Notably, RTI-7470-44 shows significant species selectivity, with over 90-fold preference for hTAAR1 compared to its rat and mouse counterparts. This compound also possesses favorable pharmacokinetic properties, including good blood-brain barrier penetration, moderate metabolic stability, and a promising off-target safety profile. In electrophysiological studies, RTI-7470-44 enhanced the spontaneous firing rate of dopaminergic neurons in the mouse ventral tegmental area (VTA) and effectively counteracted the effects of the TAAR1 agonist RO5166017.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
