Fingolimod hydrochloride C화학적 특성, 용도, 생산
개요
Approved by the U.S. FDA in September 2010, fingolimod (also referred
to as FTY720) is the first approved oral therapy for the relapsing-remitting
form ofmultiple sclerosis (RRMS). Because of fingolimod’s structural
resemblance to sphingosine, a metabolite of sphingolipids that constitutes
the cell membrane of all eukaryotic cells, it was hypothesized that
fingolimod may be affecting sphingolipid metabolism in cells. A series of
elegant in vitro and in vivo studies confirmed that fingolimod is
converted to (S)-fingolimod phosphate primarily by sphingosine kinase-
2 and that (S)-fingolimod phosphate mediates multiple biological processes
by binding to novel GPCR’s referred to as sphingosine-1-phosphate (S1P)
receptors. S1P receptors are divided into five subtypes, S1P
1–5, which have
varying tissue and cellular distribution. S1P
1–3 receptors are ubiquitously
expressed in the immune, cardiovascular, and central nervous systems, S1P4
is restricted to the hematopoietic system, and S1P
5 is mostly localized in the
white matter of CNS. S1P
1–3 receptors play important roles in endothelial
barrier function, maintaining vascular tone, regulating heart rate and allowing
for lymphocyte egress fromsecondary lymphoid organs. The functional
role of S1P
4 is unknown,while the S1P5 receptor is thought to be involved in
natural killer cell trafficking and oligodendrocyte function.

용도
Fingolimod Hydrochloride is a derivative of ISP-1 (myriocin), a fungal metabolite of the Chinese herb Iscaria sinclarii as well as a structural analogue of Sphingosine. Fingolimod is a novel immune modulator that prolongs allograft transplant survival in numerous models by inhibiting lymphocyte emigration from lymphoid organs. Fingolimod is reported to be phosphorylated by sphingosine kinase to FTY720-P, which has been shown to potently stimulate GTPgS binding activity in S1P-transfected CHO cells (EC50 = 210 pM, 4.9 nM, 4.3 nM, and 1 nM for S1P1, S1P3, S1P4 and S1P5, respectively).
정의
ChEBI: The hydrochloride salt of 2-amino-2-[2-(4-octylphenyl) ethyl]-1,3-propanediol (fingolimod).
Clinical Use
Fingolimod hydrochloride is an immunosuppressive drug developed by Novartis and approved in the
U.S., Europe, and Australia in 2010 for the treatment of multiple sclerosis. The structure of
fingolimod derives from the naturally-occurring myriocin (ISP-1) metabolite of the fungus I. sinclairii
and the aminoalcohol functionality within the drug possesses structural similarity to the sphingosine
family of natural products.
