BICYCLIC COMPOUNDS

Disclosed are compounds of Formula (I) 112-. (canceled) This application is a continuation of U.S. application Ser. No. 14/798,498, filed Jul. 14, 2015, which claims priority to U.S. application Ser. No. 14/185,164, filed Feb. 20, 2014, which claims priority to U.S. Provisional Application No. 61/767,531 filed on Feb. 21, 2013, whose contents are hereby incorporated by reference.The present invention generally relates to bicyclic compounds useful as S1Pagonists. Provided herein are bicyclic compounds, compositions comprising such compounds, and methods of their use. The invention further pertains to pharmaceutical compositions comprising at least one compound according to the invention that are useful for the treatment of conditions related to S1Pmodulation, such as autoimmune diseases and vascular disease.Sphingosine-1-phosphate (S1P) is a zwitterionic lysophospholipid metabolite of sphingosine (Sph), which in turn is derived from enzymatic cleavage of ceramides. Enzymatic phosphorylation of Sph by two kinases (SphK1 and SphK2) leads to the production of S1P largely from erythrocytes, but also from a radiation resistant source, possibly the lymphatic endothelium (Pappu, R. et al., 316:295-298 (2007)). Originally thought to operate solely as an intracellular signaling molecule, S1P was subsequently identified as a high affinity ligand for five members of the endothelial differentiation gene (EDG) class of G-protein coupled receptors (GPCRs) named S1Por S1P1, S1Por S1P2, S1Por S1P3, S1Por S1P4, and S1Por S1P5 (formerly called EDG-1, EDG-5, EDG-3, EDG-6, and EDG-8, respectively) (Chun, J. et al., 62:579-587 (2010)). The interaction of S1P with the S1P receptors plays a fundamental physiological role in a large number of processes including cell proliferation, cell morphology, tumor cell invasion, angiogenesis, tumorigenesis, cytoskeletal rearrangement, vascular development, and lymphocyte trafficking (Olivera, A. et al., 716:123-142 (2011)). S1P receptors are ...

The invention also relates to said iodo- or astatoarene and diaryliodonium compound as such. The invention also concerns a method of synthesizing a iodo- or astatolabelled biomolecule and/or vector using said iodo- or astatoarene. 115-. (canceled) The present invention concerns a method of synthesizing a iodo- or astatoarene comprising the reaction of a diaryliodonium compound with a iodide or astatide salt, respectively. The invention also relates to said iodo- or astatoarene and diaryliodonium compound as such. The invention also concerns a method of synthesizing a iodo- or astatolabelled biomolecule and/or vector using said iodo- or astatoarene.Aryliodonium salts have become increasingly popular in the last decades for arylation of nucleophiles thanks to their low toxicity, the high regioselectivity they allow and the mild reaction conditions they require compared to conventional methods. Halogens were amongst the first nucleophiles to be closely investigated for the nucleophilic aromatic substitution of aryliodonium salts more than 50 years ago. Yet, this is only recently that applications related to halogenation with these precursors have been developed, especially in radiochemistry with the radiolabelling of arenes with the β-emitter fluorine-18 for positron emitted tomography (PET).In contrast to F, the other radiohalogens have received limited attention for reaction with iodonium salts. For instance, no report exists as to the reactivity of radioactive bromide, iodide and astatide.Many of the radioiodinated and astatinated compounds of interest in nuclear medicine are aromatic derivatives since non-aromatic compounds often exhibit poor stability due to the weakness of the C—I and C—At bonds. These aromatic compounds are generally obtained by conventional methods such as nucleophilic ...

CARBON NANOBELT AND PRODUCTION METHOD THEREFOR

A carbon nanobelt represented by formula (1) was synthesized by chemical synthesis: 3. The carbon nanobelt according to claim 1 , wherein Ar in formula (1) or formula (1A) represents a benzene ring or a naphthalene ring.4. The carbon nanobelt according to claim 1 , wherein n in formula (1) or formula (1A) represents an integer of 0 to 10. The present invention relates to carbon nanobelts and production methods for them.Cyclic aromatic compounds that serve as a partial framework of a carbon nanotube (CNT) are a group of promising molecules expected to exhibit various types of functional expression and to have a variety of applications, such as their specific electronic properties due to n-conjugation, inclusion of a guest molecule through a hole inside the compound, and the use of the compound in synthesis of CNT (e.g., see NPL 1). In particular, cyclic aromatic compounds have recently drawn attention as a template molecule for bottom-up synthesis of CNT, which will enable the construction of uniformly structured CNT, which has been difficult to create by traditional methods (e.g., see NPL 2). A study reports that CNT can be synthesized by a CVD method, using a cycloparaphenylene compound (CPP) having benzene rings cyclically attached at their para-position as a template molecule.However, cyclic aromatic compounds synthesized thus far, including CPP, are formed such that the target ring structure is cyclically single bonded; thus, cleavage of a single carbon-carbon bond easily opens the cyclic structure. A group of molecules that have aromatic rings curved like a belt, and that require cleavage of at least two carbon-carbon bonds to open the ring structure, are defined as carbon nanobelts (e.g., see NPL 3). A carbon nanobelt is the smallest unit of CNT that can be illustrated as a molecule, and is expected to be more rigid than conventional cyclic aromatic compounds, showing promise as an excellent template molecule in characteristic evaluation of CNT and CNT ...
