摘要:
The invention is concerned with 7H-dibenzo(a,c)-cyclohepten-5-one-(7) derivatives of general formula I ##STR1## wherein R.sup.1 and R.sup.2 can be the same or different, a hydrogen atom, an alkyl radical containing 1 to 3 carbon atoms, or, together with the nitrogen atom to which they are attached form a heterocyclic ring containing 3 to 6 carbon atoms,n is 2 or 3R.sup.3 is a hydrogen atom or a halogen atom andX is either a methylene radical or an oxygen atomand the pharmacologically acceptable salts thereof with inorganic and organic acids.The invention is furthermore concerned with analogous processes for the preparation thereof and their application for controlling psychic diseases and gastric and/or intestinal ulcers.
摘要:
The present invention provides compounds of the general formula: ##STR1## wherein R.sub.1, R.sub.2, R.sub.3, R.sub.4 and R.sub.5 may be the same or different and are hydroxy, straight or branched-chain alkoxy of from 1 to 5 carbon atoms, phenoxy, benzyloxy, two adjacent groups may be methylenedioxy, or hydrogen provided R.sub.4 and R.sub.5 are not simultaneously hydrogen; R.sub.6 is hydrogen, straight or branched-chain alkyl of from 1 to 5 carbon atoms, straight or branched-chain alkenyl of from 2 to 5 carbon atoms, cycloalkylalkyl of from 4 to 7 carbon atoms, alkoxy carbonyl of from 2 to 6 carbon atoms, trifluoroacetyl, aralkyl of from 5 to 11 carbon atoms, or acyl which is derived from an aliphatic, araliphatic or aromatic carboxylic acid of from 1 to 11 carbon atoms; and the pharmaceutically acceptable salts thereof; excluding 5,6,6a,7-tetrahydro-1-hydroxy-2,9,10trimethoxy-5-methyl-4H-dibenz(de,g)-isoquinoline and 5,6,6a,7-tetrahydro-1,2,9,10-tetramethoxy-5-methyl-4H-dibenz(de,g)isoquinoline.The present invention also provides a process for the preparation of these compounds and pharmaceutical compositions containing them. Furthermore, the present invention is concerned with the use of these compounds for treating diseases of the central nervous system.
摘要:
New organic nitrate compounds, formed by condensing a nitrato alkanoic acid with a sulfur-containing amino acid or peptide followed by the reaction of the resulting product with an amino acid, N-acylamino acid, peptide or an N-acyl peptide to produce a thio ester thereof, which prevent nitrate tolerance or overcome existing tolerance and which are useful for the treatment of cardiac diseases including circulatory diseases, coronary dilation, high blood pressure, cardiac insufficiency and for dilating the peripheral vessels.

Pharmaceutical compositions for administration by inhalation, wherein calcium-antagonists are employed as the active substances, e.g., metered-sprays of calcium-antagonists, in particular of diltiazem and a process for their manufacture are described.
摘要:
This invention provides compounds of the general formula I ##STR1## wherein R.sup.1 and R.sup.2 independently represent groups selected from the group consisting of straight chain alkyl groups; branched chain alkyl groups; aryl groups; optionally substituted aryl groups and the groups required to complete a ring system together with the sulphur atom;R.sup.3 and R.sup.4 independently represent groups selected from the group consisting of hydrogen; straight chain alkyl groups; branched chain alkyl groups and optionally substituted aryl groups;R.sup.5 and R.sup.6 independently represent groups selected from the group consisting of alkyl groups and the groups required to complete a heterocyclic ring together with the nitrogen atom; the groupR.sup.7 represents a group selected from the group consisting of hydrogen; straight chain alkyl groups and branched chain alkyl groups;X represents an anion of a physiologically acceptable acid andn represents a number selected from the group consisting of 0 and 1.The compounds show pharmacological activity, for example, as spasmolytics and broncholytics.
摘要:
A compound selected from a 2,4-diamino-5-thiobenzylpyrimidine of the formula: ##STR1## in which R is selected from hydrogen, alkyl, lower alkoxy, and halogen and R' is alkyl; and pharmacologically acceptable acid addition salts thereof. These compounds have an anti-bacterial action and are sulphonamide potentiators.
