The sphingosine-1-phosphate-1 (S1P1) receptoragonists have great potential for the treatment of multiple sclerosis (MS) because they can inhibit lymphocyte egress through receptor internalization. We designed and synthesized triazole and isoxazoline derivatives to discover a novel S1P1 agonist for MS treatment. Of the two scaffolds, the isoxazoline derivative was determined to have excellent in vitro
Provided is a 2H-chromene compound or a derivative thereof which has an excellent S1P1 agonist action. The 2H-chromene compound or derivative is particularly useful for preventing and/or treating a disease induced by undesirable lymphocyte infiltration or a disease induced by abnormal proliferation or accumulation of cells.

Xanthine oxidase is a key enzyme that catalyses hypoxanthine and xanthine to uric acid, whose overproduction leads to the gout-causing hyperuricemia. In this study, a series of 1-hydroxy/methoxy-4-methy1-2-phenyl-1H-imidazole-5-carboxylic acid derivatives (4a-4k and 6a-6k) was synthesized and evaluated for their inhibitory potency against xanthine oxidase. The 1-hydroxyl substituted derivatives 4a-4k showed excellent inhibitory potency with IC50 values ranging from 0.003 mu M to 1.2 mu M, with compounds 4d (IC50 = 0.003 mu M), 4e (IC50 = 0.003 FM), and 4f (IC50 = 0.006 mu M) manifesting the most potent xanthine oxidase inhibitory potency that were comparable with that of Febuxostat (IC50 = 0.01 410). Lineweaver-Burk plot analysis revealed that representative compound 4f acted as a mixed-type inhibitor for xanthine oxidase. The basis of significant inhibition of xanthine oxidase by 4f was rationalized by its molecular docking into the active site of xanthine dehydrogenase. (C) 2015 Elsevier Masson SAS.
