`
`in the treatment or
`to use of an S1P receptor modulator the
`
`
`associated
`with a demyelinating disease,
`
`e.g.
`multiple
`
`S1 P receptor modulators are typically sphingosine analogues,

`or

`2-amino-propanol derivatives, e. g. a compound comprising a

`Sphingosine-1 phosphate (hereinafter "S1P*) is a natural serum lipid. Presently there are
`eight known S1P receptors, namely S1P1
`to

`receptors,
`
`
`e.g. S1P1 to S1P8. Agonist binding to S1P receptor a

`
`
`
`receptors may be
`
`by quantifying
`
`The binding affinity of S1P receptor modulators to individual human S1P
`determined in following assay:
`SIP receptor modulator activities of compounds are tested on the human S1P receptors
`SI Pi, SIP2, SIPj,
`and SIP5. Functional receptor
`activation
`is
`assessed
`SIP4
`compound induced GTP [y-^S] binding to membrane protein prepared from transfected
`CHO or RH7777 cells stably expressing the appropriate human S1P receptor. The assay
`technology used is SPA (scintillation proximity based assay). Briefly, DMSO dissolved
`compounds are serially diluted and added to SPA- bead (Amersham-Pharmacia)
`immobilised SIP
`receptor expressing membrane protein (10-20ng/well) in the presence of
`50 mM Hepes, 100 mM NaCI. 10 mM MgCfe, 10 pM GDP, 0.1% fat free BSA and 0.2 nM
`GTP ft-^Sl (1200 Ci/mmol). After incubation in 96 well microtiterplates at RT for 120 min,
`unbound GTP fr-^S] is separated by a centrifugation step. Luminescence of SPA beads
`triggered by membrane bound GTP
`is quantified with a TOPcount plate reader
`(Packard). EC30S are calculated using standard curve fitting software. In this assay, the
`S1P
`receptor modulators preferably have
`
`a
`
`
`
`binding receptor <50 nM. affinity to

`
`Preferred S1P
`binding properties also
`
`
`have accelerating lymphocyte homing properties, e.g. compounds
`which elicit a lymphopenia resulting from a re-distribution, preferably reversible,
`of
`lymphocytes from circulation
`to secondary lymphatic tissue, without evoking a generalized
`immunosuppression. Naive
`
`
`cells are sequestered; CD4 and CD8 T-cells and B-cells from
`the blood are stimulated to migrate

`with each episode, yet remain clinically stable between relapses. About 65% of patients
`initially experience the RR form of MS, but within 10 years about half will develop the
`secondaiy progressive form.
`• Secondary-progressive
`(SP-MS): Initially RR followed by gradually increasing disability,
`with or without relapses. Major irreversible disabilities appear most often during SP.
`• Primary-progressive (PP-MS): Progression disease course from onset without any
`relapses or
`remissions,
`
`affecting about 15% of MS patients.

`relapses; periods between
