Abstract
Sphingosine 1-phosphate (S1P) evokes a plethora of physiological responses by stimulating members of a G protein-coupled receptor family, known as S1P receptors. Currently five different mammalian S1P receptor subtypes, S1P1-5, each with a different cellular expression pattern, were identified. The S1P1 receptor in particular has attracted major interest throughout the pharmaceutical industry following the breakthrough discovery that this S1P receptor subtype is critically involved in the regulation of lymphocyte trafficking through secondary lymphoid organs. Since then, examples of synthetic S1P1 agonists with lymphocyte reducing and immunomodulating activity demonstrated efficacy in numerous preclinical models of autoimmune disease and transplantation. Notably FTY720 (fingolimod), a pro-drug that is phosphorylated in vivo and converted into a non-selective S1P1,3,4,5 receptor agonist, has been widely used to increase the understanding of S1P1 receptor biology. Results from recently completed phase III clinical trials using FTY720 paved the way for this non-selective S1P1 receptor agonist to become the first oral therapy in multiple sclerosis, with potential expansion into many other autoimmune diseases. This review briefly outlines the field of S1P1 receptor biology and summarizes recent approaches in medicinal chemistry to discover potent and selective S1P1 receptor agonists. In particular, the complexity of discovering a molecule akin to FTY720 but with an improved side-effect profile will be discussed.

From Biodiversity to Chemical Diversity: Focus of Flavonoids
Flavonoids are the largest group of polyphenols, plant secondary metabolites arising from the essential aromatic amino acid phenylalanine (or more rarely from tyrosine) via the phenylpropanoid pathway. The flavan nucleus is the basic 15-carbon skeleton of flavonoids (C6-C3-C6), which consists of two phenyl rings (A and B) and a heterocyclic ...read more
