Etrasimod

SKU: orb1296117

Description

Etrasimod (APD334) is a potent and selective oral S1P1 receptor antagonist, with an IC50 of 1.88 nM in CHO cells. It is a valuable research tool for investigating S1P1 signaling in autoimmune and inflammatory disease models, both in vitro and in vivo.

Bioactivity

• Target IC50:
  S1P1:1.88 nM (CHO cells)
• In Vivo:
  APD334 has a relatively low systemic clearance (<4% of hepatic blood flow) and high Cmax across all species. In both dog and monkey, a significant decrease in the volume of distribution (Vss) is observed relative to the rodent. Oral bioavailability is in the range of 40–100% and the terminal phase half-life varied from 6 h in monkey, to as long as 29 h in the dog.

• In Vitro:
  In CHO cells expressing HA-tagged S1P1, APD334 is found to have an IC50 value of 1.88 nM. Moderate agonism at human S1P4 and S1P5 is observed but is reduced relative to S1P1, both in terms of potency and efficacy. APD334 is devoid of any agonism or antagonism at human S1P2 and S1P3.

• Animal Research:
  APD334 induced effects on blood lymphopenia are determined in male Sprague-Dawley rats. Briefly, male rats are given a 0 (vehicle only), 0.03 (mice only), 0.1, 0.3 or 1 mg/kg oral dose of APD334 formulated in 0.5% methylcellulose (MC) in water. Rat blood samples are collected at 0, 1, 3, 5, 8, 16, 24, 32, 48 and 72 hours post-dose. APD334 induced effects on blood lymphopenia are determined in male BALB/c mice. Briefly, male mice are given a 0 (vehicle only), 0.03 (mice only), 0.1, 0.3 or 1 mg/kg oral dose of APD334 formulated in 0.5% methylcellulose (MC) in water. Mouse blood samples are taken at 0, 1, 3, 5, 8, 16, 24 and 32 hours post-dose.
