摘要:
Heterocyclic substituted 2-acylamino-5-thiazoles, their preparation and pharmaceutical compositions containing them.A 2-Acylaminothiazole of formula: ##STR1## in which R.sub.1 is H, an alkyl or a substituted alkyl; R.sub.IV is a cycloalkyl, an aromatic group such as phenyl or a heterocyclic group which are unsubstituted or substituted; R.sub.V is a substituted alkyl, a substituted carboxy such as an ester or an amide; or R.sub.IV and R.sub.V together represent a phenoxyalkylene group which may be substituted on the phenyl; and Z is a heterocyclic e.g. indolyl group; or a salt of compound (I).
摘要:
The present invention relates to new pyrazole derivatives possessing an amide group substituted with an amino acid or one of its derivatives at position 3 and variously substituted in positions 1, 2, 4 or 5 of the pyrazole ring, to a process for preparing these and to pharmaceutical compositions containing the said pyrazole derivatives as an active ingredient.
摘要:
The present invention relates to pyridazine derivatives of formula: ##STR1## which are useful as ligands of cholinergic receptors, in particular, receptors of the M.sub.1 type.
摘要:
The invention relates to substituted 1-naphyl-3-pyrazolecarboxamides of formula I: ##STR1## These compounds are useful for the treatment of neuropsychiatric disorders, especially those associated with a dysfunction of the dopaminergic systems.
摘要:
The invention relates to the use of 5-alkylpyridazine derivatives of the formula ##STR1## in which R.sub.1 is a C.sub.1 -C.sub.4 alkyl group or a phenyl group and R.sub.2 and R.sub.3 independently are a C.sub.1 -C.sub.4 alkyl group, or R.sub.2 and R.sub.3, taken with the nitrogen atom to which they are bonded, form a morpholino group, or one of their pharmaceutically acceptable salts, for the preparation of pharmaceutical compositions for combating pathological conditions associated with a cortical cholinergic deficiency, especially for the treatment of degenerative syndromes associated with senescence.
