体外研究 (In Vitro)
Stable heavy isotopes of hydrogen, carbon, and other elements have been incorporated into drug molecules, largely as tracers for quantitation during the drug development process. Deuteration has gained attention because of its potential to affect the pharmacokinetic and metabolic profiles of drugs[1].

Fingolimod hydrochloride (FTY720), an analog of sphingosine, is a potent sphingosine 1-phosphate (S1P) receptors modulator. Fingolimod hydrochloride is phosphorylated by sphingosine kinases, particularly by SK2, and then binds S1PR1, 3, 4, and 5. Fingolimod hydrochloride induces the internalization of S1P1, and consequently, inhibits S1P activity. Fingolimod hydrochloride also is a pak1 activator[1][4].

体外研究 (In Vitro)
Fingolimod hydrochloride (FTY720) is a S1P antagonist with an IC50 of 0.033 nM in K562 and NK cells[1]. The monocyte-derived immature dendritic cells (iDCs) are pretreated with various concentrations of S1P for various periods of time prior to their incubation with NK cells. Four hours incubation of autologous or allogeneic iDCs with 0.2-20 μM of S1P significantly protectes these cells from NK cell lysis. The IC50 values of S1P are calculated at 160 nM for autologous iDCs, and 34 nM for allogeneic iDCs. Next, the inhibitory effect of S1P is revered by various concentrations of Fingolimod hydrochloride (FTY720) or SEW2871, with an IC50 effect of 173 or 15 nM, respectively[1]. The immunomodulator Fingolimod hydrochloride (FTY720) is a structural analogue of S1P and acts in its phosphorylated isoform as an unselective agonist on S1P1 and S1P3-5 and a selective functional antagonist on S1P1. FTY720 enhances serum S1P levels by inhibiting S1P lyase activity[2]. The number of Iba1+ cells in ipsilateral CA3 is counted, and the corresponding graph shows a significantly lower number of Iba1+ cells in CA3 of the Kainic acid (KA)+FTY720 group than in CA3 of KA group[3].

体内研究 (In Vivo)
Administration of the immunomodulator Fingolimod hydrochloride (0.1 mg/kg i.v.) increases serum S1P, improves impaired systolic contractility and activates the PI3K-pathway in the heart. Administration of Fingolimod hydrochloride (FTY720) causes a significant rise in serum S1P levels in both sham-operated animals and animals challenged with LPS/PepG (P<0.0001)[2]. FTY720 attenuates microgliosis, modulates the microglia inflammatory phenotype by reducing LPS-mediated activation of p38 MAPK signalling pathway. Thus, FTY720 shares both direct neuroprotective and anti-inflammatory properties that can contribute to overall neuroprotection. In particular, the potential of FTY720 to switch microglia phenotype from a detrimental to a protective one represents a therapeutic mechanism for attenuating acute and chronic CNS damage[3].

Cell Assay [1]
Immature dendritic cells (DCs) are left intact or are incubated with 2 μM S1P, 10 nM Fingolimod hydrochloride, 10 nM SEW2871 or the combinations of S1P with these drugs for 4 h. As a control 1 μg/mL LPS is used. The cells are washed and incubated in a 96-well plate (v-bottom, 2×105 cells per well), washed again and resuspended in PBS buffer containing 0.1% sodium azide. They are labeled with 1 μg/mL FITC-conjugated mouse anti-human CD80, 1 μg/mL FITC-conjugated mouse anti-human CD83, 1 μg/mL FITC-conjugated mouse anti-human CD86, 1 μg/mL FITC-conjugated mouse anti-human HLA-class I, 1 μg/mL FITC-conjugated mouse anti-human HLA-DR, 1 μg/mL FITC-conjugated mouse anti-human HLA-E, or 1 μg/mL FITC-conjugated mouse IgG as a control. The cells are washed twice, and examined in the flow cytometer. Markers are set according to the isotype control FITC-conjugated mouse IgG[1].

Animal Administration [2][3]
Mice[2] This study is carried out on 2-month-old male C57BL/6J mice or sphingosine kinase-2 deficient (SPHK-2-/-) mice weighing 25-30 g, receiving a standard diet and water ad libitum. C57BL/6J wild-type or SPHK-2-/- mice receives i.p.-injections of LPS (9 mg/kg)/PepG (1 mg/kg) or its vehicle (0.9% saline). Sham mice are not subjected to LPS/PepG, but are otherwise treated in the same way. At 1 h after LPS/PepG challenge, mice are treated with Fingolimod hydrochloride (0.1 mg/kg i.v.) or its vehicle (10% DMSO). To elucidate the role of different S1P receptors in the observed effects of Fingolimod hydrochloride, mice receive (45 min after LPS/PepG and 15 min prior to Fingolimod hydrochloride) the selective PI3K inhibitor LY294002 (0.3 mg/kg i.v.) or the selective S1P2 receptor antagonist JTE 013 (1 mg/kg i.v.) or (1 h after LPS/PepG) the selective S1P1 receptor agonist SEW2871 (1 mg/kg i.v.) or vehicle (10% DMSO). Rat[3] The Sprague-Dawley rats (200 to 250 g) are used. Fingolimod hydrochloride is applied icv (1 μg/2 μL), together with Kainic acid (KA), plus intraperitoneally (ip; 1 mg/kg) 24 h before, and daily, until sacrifice 3 days aftericv. Rats are evaluated for neurological score, neuronal loss in CA3 hippocampal region and activation of microglia at the lesion site.

Fingolimod has been reported to reduce LPA synthesis via inhibition of the lysophospholipase autotaxin. Fingolimod treatment correlates with a significant elevation of axonal cAMP, a crucial factor for axonal outgrowth. Additionally, Fingolimod significantly reduces LPA levels in the injured nerve. PF-8380 treatment correlates with improved myelin thickness[2].

体内研究 (In Vivo)
Fingolimod treatment results in significantly increased nerve conduction at 14 days post-crush in wildtype C57BL/6 mice. However, Foxn1-/- mice, which are devoid of T- but not B-lymphocytes, show an improvement of nerve regeneration under fingolimod treatment. Although the mean increase in nerve conduction velocity in both fingolimod-treated and controlFoxn1-/- mice implies a potentially positive role of T-lymphocyte deficiency on nerve regeneration, only fingolimod-treated Foxn1-/- mice show a significant improvement compared to C57BL/6 controls and performed better in the functional analysis[2]. Treatment of the animals with Fingolimod for 28 d results in a clear reduction in the binding of 18F-GE180 when compare with vehicle-treated animals and evaluated by ex vivo autoradiography. Quantification of the binding of the radiotracer revealed a significant reduction in the binding potential of 18F-GE180 (P<0.0001) after treatment with Fingolimod[3].

Animal Administration [2][3]
Mice[2] Rag1-/- mice(B6.129S7-Rag1tm1Mom/J), Foxn1-/- mice (B6.Cg/NTac-Foxn1nu) mice, and control C57BL/6 mice are used. Mice receive non-phosphorylated Fingolimod via intraperitoneal injection at a concentration of 1 mg/kg once daily over the course of 16 days, starting 2 days before crush until 14 days post-crush. PF-8380 is dissolved in DMSO and administered at a concentration of 10 mg/kg via intraperitoneal injection once daily, as well starting 2 days before until 14 days post-crush. Controls receive an equal volume of solvent. Rats[3] Male Lewis rats (50-100 g, n=18) are used. After the peripheral activation of the lesion, the DTH EAE lesions are allowed to develop until day 127 to generate large chronic lesions and the animals are then treated for 28 d with either Fingolimod (n=7) or vehicle (n=7). The Fingolimod treatment is given daily (0.3 mg/kg in 0.5 mL of water). The control group is given water (0.5 mL) as a vehicle control. The animals are dosed via oral gavage to ensure accurate dosing. In this model, the acute inflammation subsides after day 20 of activation of the lesion, and the BBB damage subsides. Thus, at day 127 the lesion clearly represents a well-developed chronic MS lesion. PET imaging is performed immediately before initiation of treatment and at the end of the treatment period.
