| Fingolimod hydrochloride Usage And Synthesis |
Oral drug for the treatment of multiple sclerosis | Fingolimod hydrochloride is the first oral drug for the treatment of multiple sclerosis. It is successfully developed by the pharmaceutical company Novartis, and it has been approved for marketing by the US Food and Drug Administration (FDA). The recommended dose is 0.5mg once a day for oral administration.
Multiple sclerosis is a debilitating neurological disease that can cause the patient to lose a sense of balance, appear muscle spasms and other movement disorders. The disease has been treated with injectable drugs. This kind of medication brought great inconvenience to patients.
Fingolimod is a sphingosine-l-phosphate (S1PR) receptor modulator. After phosphorylation, It is bound to s1P receptor that is on the surface of lymphocyte, which will change lymphocyte migration, and promote cells into the lymphatic tissue, and prevent lymphocytes from leaving the lymphoid tissue and get into the graft. Thereby, it will prevent these cells from infiltrating the central nervous system (CNS), which achieves the effect of immunosuppression. According to the drug's introduction, drugmaker Novartis said that this process of pharmacological effects is reversible. If medication is stopped, the level of lymphocytes in circulating system will return to normal.

| Description | 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, S1P1–5, which have
varying tissue and cellular distribution. S1P1–3 receptors are ubiquitously
expressed in the immune, cardiovascular, and central nervous systems, S1P4
is restricted to the hematopoietic system, and S1P5 is mostly localized in the
white matter of CNS. S1P1–3 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 S1P4 is unknown,while the S1P5 receptor is thought to be involved in
natural killer cell trafficking and oligodendrocyte function. | Chemical Properties | White Solid | Originator | Yoshitomi Pharmaceutical Industries

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). | Uses | FTY720 is a derivative of ISP-1 (myriocin), a fungal metabolite of the Chinese herb Iscaria sinclarii as well as a structural analogue of Sphingosine.

Phosphorylation of FTY270 by sphingosine kinase causes S1P1R internalization, which sequesters lymphocytes in lymph nodes, preventing them from taking part in an autoimmune response. Clinically, it has been approved for the treatment of multiple sclerosis (MS). It has also been shown to block and reverse paclitaxel-induced chemotherapy induced peripheral neuropathy (CIPN) through S1PR inhibition as well as inhibit the activity of histone deacetylases in the hippocampus of mouse brains, thereby modulating memory. | 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. | Synthesis | Although several convenient preparations of fingolimod (FTY720)
have been reported in the literature, the route most closely resembling the process-scale
approach is described in the scheme. Friedel-Crafts acylation of commercial toluene derivative 89
with bromoacetyl chloride followed by ethoxide-mediated N-acylated aminomalonate (91) attack onto
the resulting -bromoketone 90 gave rise to ketoamide 92 in good overall yield. Next, separate hydride
reduction protocols were employed to furnish diol 93. Presumably, triethylsilyl hydride reduced the
ketone and both ethyl esters within 92 to the corresponding diacid, which then underwent lithium
aluminum hydride treatment to arrive at diol 93. Careful attention to stoichiometry was required to
avoid over reduction of amide 93, which was critical to achieve high-yielding (76%) salt formation of
fingolimod HCl (VI) through the use of 6 N ethanolic hydrochloric acid. ![Synthesis_162359-56-0](https://www.chemicalbook.com/NewsImg/2021-02-09/20210209490008881457302032.jpg)
