Synthesis and evaluation of CS-2100, a potent, orally active and S1P(3)- sparing S1P(1) agonist.[Pubmed:22405291]
Eur J Med Chem. 2012 May;51:92-8.
Modulators of sphingosine phosphate receptor-1 (S1P(1)) have recently been focused as a suppressant of autoimmunity. We have discovered a 4-ethylthiophene-based S1P(1) agonist 1-({4-Ethyl-5-[5-(4-phenoxyphenyl)-1,2,4-oxadiazol-3-yl]-2-thienyl}methyl)azetidi ne-3-carboxylic acid (CS-2100, 8) showing potent S1P(1) agonist activity against S1P(3) and an excellent in vivo potency. We report herein the synthesis of CS-2100 (8) and pharmacological effects such as S1P(1) and S1P(3) agonist activity in vitro, peripheral blood lymphocyte lowering effects and the suppressive effects on adjuvant-induced arthritis and experimental autoimmune encephalomyelitis (EAE) in animal models. The pharmacokinetic data were also reported. CS-2100 (8) had >5000-fold greater agonist activity for human S1P(1) (EC(50); 4.0 nM) relative to S1P(3) (EC(50); >20,000 nM). Following administration of single oral doses of 0.1 and 1 mg/kg of CS-2100 (8) in rats, lymphocyte counts decreased significantly, with a nadir at 8 and/or 12 h post-dose and recovery to vehicle control levels by 24-48 h post-dose. CS-2100 (8) is efficacious in the adjuvant-induced arthritis model in rats (ID(50); 0.44 mg/kg). In the EAE model compared to the vehicle-treated group, significant decreases in the cumulative EAE scores were observed for 0.3 and 1 mg/kg CS-2100 (8) groups in mice. While CS-2100 (8) showed potent efficacy in various animal disease models, it was also revealed that the central 1,2,4-oxadiazole ring of CS-2100 (8) was decomposed by enterobacteria in intestine of rats and monkeys, implicating the latent concern about an external susceptibility in its metabolic process in the upcoming clinical studies.
Discovery of CS-2100, a potent, orally active and S1P3-sparing S1P1 agonist.[Pubmed:22264485]
Bioorg Med Chem Lett. 2012 Feb 15;22(4):1788-92.
S1P(3)-sparing S1P(1) agonists have attracted attention as a suppressant of autoimmunity with reduced side effects. Our synthetic efforts and extensive SAR studies led to the discovery of 10b named CS-2100 with the EC(50) value of 4.0 nM for human S1P(1) and over 5000-fold selectivity against S1P(3). The in vivo immunosuppressive efficacy was evaluated in rats on host versus graft reaction and the ID(50) value was determined at 0.407mg/kg. The docking studies of CS-2100 with the homology model of S1P(1) and S1P(3) showed that the ethyl group on the thiophene ring of CS-2100 was sterically hindered by Phe263 in S1P(3), not in the case of Leu276 in S1P(1). This observation gives an explanation for the excellent S1P(3)-sparing characteristic of CS-2100.
