摘要:
The invention concerns 2-aminithiazoline derivatives of formula (I) wherein: either R1 is a hydrogen atom or an alkyl radical and R2 is an alkyl, -alk-NH2, -CH-R3, -CH2-S-R4 or phenyl radical substituted by a nitro or NH-C(=NH)CH3 radical; or R1 is an alkyl radical and R2 is a hydrogen atom; R3 is a cycloalkyl (3-6C), pyridyl, pyridyl N-oxide, thienyl, thiazolyl, imidazolyl, pyrazinyl, triazolyl, phenyl or phenyl radical substituted by a nitro, hydroxy or carboxy radical; R4 represents a pyridyl or pyridyl N-oxide radical; alk represents an alkylene radical or their pharmaceutically acceptable salts excluding some known compounds, and the use of said derivatives as inducible NO-synthase inhibitors.
摘要:
The invention concerns pharmaceutical compositions containing as active principle a 4,5-dihydro-1,3-thiazol-2-ylamine of formula (I) wherein: R represents an -alk-S-alk-Ar, phenyl or phenyl radical substituted by alkoxy or halogen or one of its pharmaceutically acceptable salts, the novel derivatives of formula (I) and their preparation. Said compounds are useful for preventing and treating diseases wherein is involved abnormal production of nitrogen monoxide (NO) by induction of inducible NO-synthase (NOS-2).

摘要:
Compounds of formula (I), wherein R is a hydrogen atom or a -COOH, -alk-COOH, -PO3H2, -CH2-PO3H2, or -CH=CH-COOH radical, or a phenyl radical substituted by a carboxy radical, R1 is an alk-CN, -alk-COOH, -alk-Het, alk-PO3H2 or -alk-CO-NH-SO2R2 radical, R2 is an alkyl or phenyl radical, alk is an alkyl radical, Het is a saturated or unsaturated mono- or polycyclic heterocyclic ring containing 1-9 carbon atoms and one or more heteroatoms selected from O, S and N, said heterocyclic ring optionally being substituted by one or more alkyl, phenyl or phenylalkyl radicals, with the proviso that when R is a hydrogen atom or a -COOH or -PO3H2 radical, R1 cannot be -alk-COOH, isomers, racemic mixtures, enantiomers and diastereoisomers thereof, salts thereof, the preparation thereof, intermediates thereof and drugs containing said compounds, are disclosed. The compounds of formula (I) have valuable pharmacological properties and are antagonists of the α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptor also known as the quisqualate receptor. Furthermore, the compounds of formula (I) are non-competitive antagonists of the N-methyl-D-aspartate (NMDA) receptor, and specifically ligands for NMDA receptor glycine modulator sites.
