The present invention relates to novel compounds of formulae (I) and (II) which are useful in the prevention, treatment and diagnosis, in vivo diagnosis of diseases or disorders related to S1P receptors, in particular, in diseases which are connected to the regulatory function of sphingosine-1-phosphate (S1P) and its analogues, such as inflammation, pain, autoimmune diseases and cardiovascular diseases.

Sphingosine-1-phosphate (S1P) influences various fundamental biological processes by interacting with a family of five G protein-coupled receptors (S1P(1-5)). FTY720, a sphingosine analogue, which was approved for treatment of relapsing forms of multiple sclerosis, is phosphorylated in vivo and acts as an agonist of four of the five S1P receptor subtypes. Starting from these lead structures we developed new agonists for the S1P(1) receptor. The biological activity was tested in vivo and promising ligands were fluorinated at different positions to identify candidates for positron emission tomography (PET) imaging after [F-18]-labelling. The radioligands shall enable the imaging of S1P(1) receptor expression in vivo and thus may serve as novel imaging markers of S1P-related diseases. (C) 2015 Elsevier Ltd. All rights reserved.

The present invention provides a diaphragm excellent in mechanical properties at high temperatures. The diaphragm comprises a cross-linked fluororubber layer obtained by cross-linking a fluororubber composition containing a fluororubber (A) and a carbon black (B), the cross-linked fluororubber layer having a loss modulus E" of 400 kPa or higher and 6,000 kPa or lower determined by a dynamic viscoelasticity test under conditions of measurement temperature: 160°C, tensile strain: 1%, static tension under a constant static load condition for measuring strain distribution: 157 cN, and frequency: 10 Hz.
