The present invention concerns novel compounds, their preparation and their uses, therapeutic uses in particular. More specifically it concerns derivative compounds having at least two aromatic cycles, their preparation and their uses, in particular in the area of human or animal health. These compounds have an affinity for the biological receptors of neuropeptide Y, NPY, present in the central and peripheral nervous systems. The compounds of the invention are preferably NPY antagonists, and more particularly antagonists of sub-type NPY Y1, and can therefore be used for the therapeutic or prophylactic treatment of any disorder involving NPY. The present invention also concerns pharmaceutical compositions containing said compounds, their preparation and their uses, as well as treatment methods using said compounds.

Rate constants for solvolyses of benzhydryl chlorides, which take place on the 10 ms to minute time scale, have been determined in aqueous acetone and acetonitrile by conductometry, using conventional conductometers as well as stopped-flow techniques. Secondary and tertiary amines were used to suppress ion recombination (common-ion return) thus giving access to the ionization rate constants k1. The

chiral γ,γ-disubstituted allylboronates in the presence of RuPhos ligand occurs with high regioselectivity and enantiospecificity, furnishing nonracemic compounds with quaternary centers. Mechanistic experiments suggest that the reaction occurs by transmetalation with allyl migration, followed by rapid reductive elimination.

The present invention is to provide a compound or a salt thereof represented by the formula:
wherein R1 is an optionally substituted hydrocarbon group or an optionally substituted heterocyclic group, the ring A is an optionally substituted divalent nitrogen-containing heterocyclic group, X′ is an optionally substituted alkylene chain, Y is an optionally substituted divalent cyclic group, X is a chemical bond or an optionally substituted alkylene chain, and Z is (1) an optionally substituted amino group, (2) an optionally substituted imidoyl group or (3) an optionally substituted nitrogen-containing heterocyclic group, or a pro-drug thereof, which have activated coagulation factor X inhibitory activity and which are useful as anti-coagulants.

2-[(Phenylthio)methyl]pyridine derivatives inhibited the dermal reverse passive Arthus reaction (RPAR) in the rat. In the same model, indomethacin was inactive, and hydrocortisone was active. Compounds Ia-d also significantly reduced exudate volume and white blood cell accumulation in the pleural RPAR. This pattern of activity was similar to that of hydrocortisone and different from that of indomethacin
