The present invention provides compounds and pharmaceutical compositions for inhibiting N-acylethanolamine acid amidase (NAAA). Inhibition of NAAA is contemplated as a method to sustain the levels of palmitoylethanolamide (PEA) and oleylethanolamide (OEA), two substrates of NAAA, in conditions characterized by reduced concentrations of PEA and OEA. The invention also provides methods for treating inflammatory diseases and pain, and other disorders in which decreased levels of PEA and OEA are associated with the disorder.

Abstract An amino acid, lethal to New Hampshire chickens (LD 50 , 150 mg/kg) was isolated from dried sclerotia of the fungus Sclerotium rolfsii (Sacc.). Purification of the rather unstable compound was effected on a cation exchange column by means of displacement chromatography and the amino acid was crystallised from 80% methanol. A structure was assigned to the compound on the basis of available
Synthetic Studies of Amino Acids by the Use of Copper Complex. II. The Condensation Reaction of<i>N</i>-Pyruvylideneglycinatocopper(II) Complexes with various Aldehydes
mechanism of the reaction which involves the base-catalyzed condensation of bis(glycinato)copper(II) with aldehydes was carried out with the purpose of improving it so that it can proceed even with lower molar equivalent ratios of aldehydes to the complex and under milder conditions. On the basis of the results reported in the literature and those of this investigation, the reaction has been carried

β-Hydroxy-Dl-norvaline(HyNva) was successfully separated into its diastereoisorners by fractional crystallization from 2-propanol as p-toluenesulfonic acid(TsOH) salts. The two racemic diastereoisorners were resolved into four stereoisomers by Vogler’s method, using diastereomers of the N-benzyloxycarbonyl Dl-amino acid and l-tyrosine hydrazide.
