Almorexant hydrochloride

SKU: orb1688486

Description

Almorexant hydrochloride is an orally bioavailable dual orexin receptor antagonist that inhibits intracellular Ca2+ signaling. It has been used in sleep research to study orexin's role in arousal and has shown effects in reducing methamphetamine-induced excitatory responses in both in vitro and in vivo models.

Bioactivity

• Target IC50:
  OX1:1.3 nM(ki)|OX2:0.17 nM(ki)
• In Vivo:
  Daily intraperitoneal injection of Almorexant hydrochloride (1.8 μmol/kg) at day 0 in mice xenografted with AsPC-1 cells and up to the mice sacrifices resulted in a significant decrease in tumor volume (> 50%), as compared to untreated mice. Treatment with Almorexant hydrochloride started after AsPC-1 tumors were developed, rapidly and strongly reduced the volume of established tumors. OX1R expression revealed by immunodetection was not affected by Almorexant hydrochloride treatment.

• In Vitro:
  AsPC-1 cells preincubated or not with the SHP2 inhibitor NSC-87877 (50 μM) were challenged for 5 min without or with 1 μM orexin-A or 1 μM Almorexant hydrochloride. In parallel, HPAF-II cells were also challenged for 5 min without or with 1 μM orexin-A. Orexin-A and Almorexant hydrochloride promote tyrosine phosphorylation of SHP2/OX1R complex.
