The addition of organocerium reagents (from both organolithium and organomagnesium precursors) to chiral aldehyde hydrazones prepared from 1-aminoproline derivatives has been studied. The additions proceed in good yield and high diastereoselectivity and with good nucleophile (Me, n-Bu, i-Pr, t-Bu, Ph, etc.) and substrate scope (alkyl, alkenyl and aryl). The resulting hydrazines can be converted to

New pyrrolotriazinone derivatives having the chemical structure of formula (I), are disclosed; as well as process for their preparation, pharmaceutical compositions comprising them and their use in therapy as inhibitors of Phosphoinositide 3-Kinases (PI3Ks)
Leukotriene A4 hydrolase (LTA4H) inhibitors, compositions containing them, and methods of use for the inhibition of LTA4H enzyme activity and the treatment, prevention or inhibition of inflammation and/or conditions associated with inflammation.
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.
A Compound represented by the following general formula (1), salts thereof or hydrates of the foregoing is a novel compound useful for treatment and/or prevention of diseases associated with thrombus formation, and which is safer with suitable physicochemical stability.
