生物活性

Fingolimod (FTY720 free base) is a sphingosine 1-phosphate (S1P) antagonist with an IC50 of 0.033 nM in K562 and NK cells. Fingolimod also is a pak1 activator, a immunosuppressant.

体外研究

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 or SEW2871, with an IC50 effect of 173 or 15 nM, respectively. 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.

体内研究

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. Treatment of the animals with Fingolimod for 28 d results in a clear reduction in the binding of F-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 F-GE180 (P<0.0001) after treatment with Fingolimod.
