ut 15

Treprostinil (Orenitram) is a potent DP1, IP and EP2 agonist (EC50: 0.6/1.9/6.2 nM).

Treprostinil Sodium (UT-15) is a potent DP1, IP and EP2 agonist (EC50: 0.6/1.9/6.2 nM).

UT-155 is a selective and potent antagonist of the androgen receptor (AR) with a binding affinity (Ki) of 267 nM for the AR ligand-binding domain (AR-LBD).

(R)-UT-155 is a selective androgen receptor degrader (SARD) ligand.

Treprostinil diethanolamine (UT-15C) is a potent agonist of EP2, DP1, and IP, with values of 3.6, 4.4, and 32.1 nM for EP2, DP1, and IP, respectively, and 212, 826, 2505, and 4680 nM for EP1, EP4, EP3, and FPKi, respectively. Treprostinil diethanolamine contributes to the upregulation of cAMP, maintaining vascular homeostasis and causing vasodilation in human pulmonary arteries.

Treprostinil Palmitil (TP), a prodrug of the DP1 and EP2 agonist Treprostinil (UT-15), exhibits EC50 values of 0.6 and 6.2 nM, respectively. It is a pure prodrug without any inherent binding affinity for G-protein coupled receptors, including prostanoid receptors.
