摘要:
Use of a compound of formula (A), wherein: W is a residue which imparts antagonistic and/or agonistic activity at histamine H3-receptors when attached to an imidazole ring in 4(5) position; R?1 and R2¿ may be identical or different and represent each independently a lower alkyl or cycloalkyl, or taken together with the nitrogen atom to which they are attached, a saturated nitrogen-containing ring (i) as defined, a non-aromatic unsaturated nitrogen-containing ring (ii) as defined, a morpholino group, or a N-substituted piperazino group as defined for preparing medicaments acting as antagonists and/or agonists at the H¿3?-receptors of histamine.
摘要:
L'invention concerne des dérivés de l'imidazole répondant à la formule générale (IA) ou (IB). Procédés pour la préparation de ces composés et composition pharmaceutique les incorporant.
摘要:
Les composés proviennent d'une amine R-NH2 ayant une forte affinité pour le récepteur H3 de l'histamine et à la fonction amine primaire de laquelle est lié un groupe déterminant une liaison lentement hydrolysable en milieu neutre. Les compositions pharmaceutiques comprennent ces composés et un véhicule ou excipient pharmaceutiquement acceptable. Ces composés sont utilisés pour la réalisation d'un médicament inhibiteur de la synthèse et de la libération d'histamine, notamment à effets sédatifs, régulateur du sommeil, anticonvulsivant, antidépresseur, antiallergique, anti-inflammatoire, antisécrétoire ou antiulcéreux.

摘要:
A method for the asymmetrical synthesis of S-acylated derivatives of 2-mercaptomethyl 3-phenyl propanoic acid of formula (I) is disclosed. The method comprises the steps of (a) preparing diol (VI) by reducing a malonic ester (V) in the presence of a hydride; (b) preparing respective monoacetates (VII R) or (VII S); (c) oxidising the monoacetates to give acids (IX S) or (IX R); (d) saponifying compounds (IX S) or (IX R) to form hydroxyacids (X S) or (X R); and (e) thioacylating hydroxyacids (X S) or (X R) with a mercaptoacid R1SH (XI) using a Mitsunobu reaction to give the desired acids (I R) or (I S), respectively. The method is useful for synthesising N-(mercaptoacyl) amino acids of formula (II).
摘要:
The compounds are derived from an R-NH2 amine with a strong affinity for the histamine H3-receptor and to the primary amine function of which is bonded a group forming a bond which can hydrolyze slowly in a neutral medium. The pharmaceutical compositions consist of these compounds and a pharmaceutically acceptable excipient. The compounds are used to produce a drug inhibiting histamine synthesis and release, and having, in particular, sedative, sleep regulating, anti-convulsive, anti-depressive, anti-allergic anti-inflammatory, anti-secretory or anti-ulcerous effects.
