摘要:
Pharmaceutical compositions for inhibiting the aggregation of erthyrocytes or thrombocytes which include phenylamides which conform to the formula: ##STR1## with R.sub.1-6, X, A and B being as defined. Processes for the preparation of novel phenylamides coming within the above formula are also discussed.
摘要:
The present invention provides tricyclic benzimidazoles of the formula ##STR1## wherein R.sub.1 is a phenyl radical of the general formula: ##STR2## wherein R.sub.2, R.sub.3 and R.sub.4 can be the same or different as in claim 1. For A, B, C and D are understood those compounds where one or two of A, B, C or D are nitrogen. These compounds are useful to inhibit the aggregation of thrombocytes and erythrocytes, lower blood pressure and can increase the power of the heart.
摘要:
Compounds of the formula I ##STR1## wherein R is a hydrogen atom or an alkyl radical, R.sub.1 is a hydrogen atom or an alkyl, alkenyl or a cycloalkyl radical, R.sub.2 is a hydrogen atom or an alkyl, alkenyl, alkylcarbonyl, alkoxycarbonyl, aminocarbonyl or hydrazinocarbonyl radical or R.sub.1 and R.sub.2, together with the carbon atom to which they are attached, form a cycloalkyl ring, X is a valency bond or an alkylene or vinylene radical, R.sub.3 is an aromatic heterocyclic five-membered ring containing 1 to 4 heteroatoms or pyridinyl which the five- and six-membered rings are optionaly substituted one or more times by alkyl, alkoxy, alkoxycarbonyl, carboxyl, alkylthio, hydroxyl, nitro, amino, halogen or cyano and the tautomers, optically-active forms and physiologically acceptable salts thereof with inorganic and organic acids.These compounds are useful for treatment of immunological disorders or autoimmune diseases such as aids/ARC, rheumatoid arthritis, lupus erythematosus and to suppress rejection reactions after organ/tissue transplants.
摘要:
The present invention is concerned with the use of compounds of the general formula: ##STR1## wherein R.sub.1 is a phenyl radical of the general formula: ##STR2## or R.sub.1 is a 5 or 6 membered heterocycle or when X is a valency bond R.sub.1 is also H, OH, mercapto, amino, alkyl, alkenyl, alkynyl, haloalkyl, alkylthio, formylaminoalkyl, pyridylcarbonylamino, cycloalkyl, or cycloalkenyl, alkoxyalkyl, carboxyalkyl, alkoxycarbonylalkyl or hydroxyalkyl of claim 1 or 2 for the preparation of pharmaceutical compositions with an erythrocyte aggregation inhibition action useful, for example, in states of shock or circulatory disturbance.
