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:
A process for the preparation of 1-hydroxyaporphine derivatives of the general formula: ##STR1## wherein R.sub.1, R.sub.3 and R.sub.4, which are the same or different, are lower alkyl, aryl or aralkyl radicals or R.sub.3 and R.sub.4 can together form a lower alkylene bridge member and R.sub.2 is a hydrogen atom or a lower alkyl, aralkyl or alkoxycarbonyl radical or an acyl radical derived from an aliphatic, aromatic or araliphatic carboxylic acid.
摘要:
The invention concerns new 5-oxo-pyrido[4,3-d]pyrimidine derivatives and the pharmacologically acceptable salts thereof, as well as a chemically novel process for the preparation of the new compounds and their use in the control of cerebral, cardiac, or peripheral vascular diseases or of stenotic symptoms.

摘要:
The invention concerns new derivatives of certain alkoxy-4(1H)-pyridones, processes for preparing them, and pharmaceutical compositions containing them. The compounds of the invention are useful in the prevention and/or treatment of heart and blood vessel diseases such as thromboses, arteriosclerosis and hypertension, and of inflammatory processes, allergies, cancers, and certain degenerative damage of the central nervous system.
摘要:
The present invention is concerned with the use of indolocarbazole imides of the general formula (I): ##STR1## for the preparation of pharmaceutical compositions for the treatment and/or prevention of cancer, virus diseases (for example HIV infections), heart and blood vessel diseases (for example high blood pressure, thromboses, heart rhythm disturbances and atheroscleroses), bronchopulmonary diseases, degenerative diseases of the central nervous system (for example Alzheimer's disease), inflammatoryl diseases (for example rheumatism and arthritis), diseases of the immune system (for example allergies), as well as psoriasis and for use as immune suppressives; as well as new compounds of general formula (I).
