  Discovery of a Selective S1P₁ Receptor Agonist Efficacious at Low Oral Dose and Devoid of Effects on Heart Rate

  摘要：

  Gilenya (fingolimod, FTY720) was recently approved by the U.S. FDA for the treatment of patients with remitting relapsing multiple sclerosis (RRMS). It is a potent agonist of four of the five sphingosine 1-phosphate (SIP) G-protein-coupled receptors (S1P(1) and S1P(3-5)). It has been postulated that fingolimod's efficacy is due to S1P(1) agonism, while its cardiovascular side effects (transient bradycardia and hypertension) are due to S1P(3) agonism. We have discovered a series of selective S1P(1), agonists, which includes 3-[6- (5-{3-cyano-4-[(1-methylethyl)oxy]phenyl}-1,2,4-oxadiazol-3-yl)-5-methyl- 3,4-dihydro-2(1H)-isoquinolinyl]propanoate, 20, a potent, S1P(3)-sparing, orally active S1P(1) agonist. Compound 20 is as efficacious as fingolimod in a collagen-induced arthritis model and shows excellent pharmacokinetic properties preclinically. Importantly, the selectivity of 20 against S1P(3) is responsible for an absence of cardiovascular signal in telemetered rats, even at high dose levels.

  2-Amino-2-(4-octylphenethyl)propane-1,3-diol 1 (fingolimod, FTY720) has been recently marketed in the United States for the treatment of patients with remitting relapsing multiple sclerosis (RRMS). Its efficacy has been primarily linked to the agonism on T cells of S1P(1), one of the five sphingosine 1-phosphate (S1P) G-protein-coupled receptors, while its cardiovascular side effects have been associated with activity at S1P(3). Emerging data suggest that the ability of this molecule to cross the blood-brain barrier and to interact with both S1P(1) and S1P(5) in the central nervous system (CNS) may contribute to its efficacy in treating patients with RAMS. We have recently disclosed the structure of an advanced, first generation S1P(3)-sparing S1P(1) agonist, a zwitterion with limited CNS exposure. In this Article, we highlight our strategy toward the identification of CNS-penetrant S1P(3)-sparing S1P(1) and S1P5 agonists resulting in the discovery of 5-(3-2-[2-hydroxy-1- (hydroxymethyl)ethyl]-5-methyl-1,2,3,4-tetrahydro-6-isoquinolinyl}-1,2,4-oxadiazol-5-yl)-2-[(1-methylethyl)oxy]benzonitrile 15. Its exceptional in vivo potency and good pharmacokinetic properties translate into a very low predicted therapeutic dose in human (< 1 mg p.o. once daily).
