Uses
Labelled rac FTY720 (F805010). rac FTY720 is a sphingosine 1-phosphate receptor modular, ameliorates experimental autoimmune encephalomyelitis by inhibition of T cell infiltration.
Definition
ChEBI: Fingolimod phosphate is a primary amino compound that is fingolimod in which one on the hydroxy groups has been converted into its dihydrogen phosphate derivative. It is the active metabolite of fingolimod. It has a role as an antineoplastic agent, an immunosuppressive agent and a sphingosine-1-phosphate receptor agonist. It is a monoalkyl phosphate, a primary amino compound and a primary alcohol. It is functionally related to a fingolimod.
Biological Activity
fty720 is sphingosine-1-phosphate (s1p) receptors agonist [1]. fty720 is a novel immunomodulatory agent derived from isp-1 (myriocin), a fungal metabolite that exists in traditional chinese herbal medicine. in higher eukaryotes, s1p is the ligand for five g-protein-coupled receptors. these s1p receptors are differentially expressed and regulate vascular maturation, angiogenesis, cardiac development and immunity. s1p receptors are important for directed cell movement [2].
in vitro
the phosphorylated fty720 acted as agonist for a family of g protein-coupled receptors in vitro. fty720 inhibited sphingosine-1-phosphate lyase activity [3]. fty720 phosphate acted as a potent agonist at sphingosine-1-phosphate (s1p) receptors s1p1, s1p3, s1p4, and s1p5 with ic50 values of 0.2-6 nm [3].
in vivo
in a variety of transplant and autoimmune models, fty720 was efficacious without inducing a generalized immunosuppressed state. fty720 was effective in human kidney transplantation. fty720 elicited lymphopenia resulting from a reversible redistribution of lymphocytes from circulation to secondary lymphoid tissues by unknown mechanisms. in a rodent model of multiple sclerosis, the phosphorylated fty720 compound was a potent agonist at four s s1p receptors. phosphorylation of fty720 acted through sphingosine 1-phosphate signaling pathways to modulate chemotactic responses and lymphocyte trafficking [1]. fty720 was phosphorylated in vivo. in mice, treatment with fty720 inhibited tissue sphingosine-1-phosphate lyase activity, whereas lyase gene and protein expression were not significantly affected [3].
