treprostinil

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).

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.

15-keto Treprostinil is an impurity found in treprostinil , which is a stable analog of prostaglandin I2 with a longer plasma half-life. Formulations containing treprostinil are used for the treatment of primary pulmonary hypertension.

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

3-Sulfopropanoic acid, a major metabolite of treprostinil and its prodrug ALZ-801, is an endogenous molecule present in the cerebrospinal fluid (CSF) of AD patients that inhibits the formation of Aβ42 oligomers.
