Orally active, highly S1P1 subtype-selective sphingosine-1-phosphate (S1P) receptor antagonist with in vitro and in vivo efficacy.
TASP0277308 is an orally active, highly S1P1 subtype-selective sphingosine-1-phosphate (S1P) receptor antagonist (IC50 = 2.7/4.2 nM against 0.1 nM S1P for binding mouse/human S1P1; IC50 >8.7 μM for S1P2-5). TASP0277308 effectively inhibits S1P1-mediated GTPγS membrane binding, cAMP response and chemotaxis (IC50 = 7.8, 3.5, 15 nM, respectively, agianst 10 nM S1P; hS1P1-expressing HEK293 or CHO) and demonstrates in vivo efficacy in various animal disease models, including collagen-induced arthritis and tumor angiogenesis in mice (10-100 mg/kg bid po), as well as neuropathic pain in rats (0.6-3 mg/kg via acute po or ip, acute 30 nmol or daily 10 nmol intrathecal injection).
