摘要:
There are described new condensed diazepinones of general formula ##STR1## wherein .circle.B represents one of the divalent groups ##STR2## and D represents the groups ##STR3## and X.sup.1, X.sup.2 represents a .dbd.CH-- group or, if .circle.B assumes the meaning of the divalent group S, U or W, they may also represent an N atom, A.sup.1 and A.sup.2 in general represent lower alkylene groups, Z represents a C--C bond or the groups, --O--, --S--, --CH.sub.2 --, or --(CH.sub.2).sub.2 --; R represents hydrogen or methyl, R.sup.1 and R.sup.2 generally represent alkyl groups which, together with the nitrogen atom between them, may also form a saturated monocylic, heterocyclic group, R.sub.3 represents alkyl, chlorine or hydrogen, R.sub.4 represents hydrogen or methyl, R.sup.5 and R.sup.6 represent hydrogen, halogen or alkyl, R.sub.7 represents hydrogen, chlorine or methyl, R.sup.8 represents hydrogen or lower alkyl, R.sup.9 represents hydrogen, halogen, lower alkyl and R.sup.10 represents hydrogen or methyl and R.sup.12 represents branched or unbranched alkyl. The compounds of general formula I and the acid addition salts thereof may be resolved into their isomers. The compounds of formula I and their salts may be used as vagal pacemakers for the treatment of bradycardia and bradyarrhythmia.
摘要:
Compounds of general formula I are described, ##STR1## wherein X represents the group .dbd.CHR, .dbd.NR or an oxygen atom andA represents the groups --NR.sup.1 R.sup.2,wherein R.sup.1 and R.sup.2 represent alkyl, cycloalkyl or phenylalkyl groups, n represents the number 0, 1 or 2, R.sup.3 represents a hydrogen atom, a hydroxy or alkyl group or a group --(CH.sub.2).sub.n --N--R.sup.5 R.sup.6 (R.sup.5 and R.sup.6 being lower alkyl groups) and R.sup.4 is an alkyl or phenylalkyl group; two processes for preparing these compounds and the salts thereof are also described.The compounds have favourable effects on heart rate and can be used as vagal pacemakers for treating bradycardia and bradyarrhythmia in human and veterinary medicine. Some of these compounds also have very good antithrombotic effects.
摘要:
Pharmaceutical compositions are described which contain 1,5,6,7-tetrahydro-4H-indazol-4-ones of the formula ##STR1## some of these substances themselves being new. The pharmaceutical compositions may be used as analgesics, antipyretics and antiphlogistics.
摘要:
Disclosed are novel pyridodiazepines. These compounds, as well certain known 6,11-dihydro-5H-pyrido[2,3-b][1,5]benzodiazepin-5-ones are useful in the treatment of AIDS, ARC and related disorders associated with HIV infection.
摘要:
Compounds of the formula ##STR1## wherein R.sub.1 is phenyl, halo- and/or methyl-substituted phenyl or pyridinyl;R.sub.2 is hydrogen, straight or branched alkyl of 1 to 4 carbon atoms, 2- or 3-hydroxy-(alkyl of 2 to 3 carbon atoms) or 2- or 3-dimethylamino-(alkyl of 2 to 3 carbon atoms);R.sub.3 is hydrogen or alkyl of 1 to 3 carbon atoms; andR.sub.4 is hydrogen, chlorine or methyl.The compounds are useful as anticonvulsants.
摘要:
Compounds of the formula ##STR1## wherein R.sub.1 is hydrogen, methyl, methoxy, fluorine or chlorine; andR.sub.2 is hydrogen, methyl, ethyl or n-propyl;and non-toxic, pharmacologically acceptable salts thereof formed with an inorganic or organic base. The compounds as well as the salts are useful as antithrombotics.
摘要:
Compounds of the formula ##STR1## wherein X is oxygen or sulfur;R.sub.1 is hydrogen, methyl or ethyl; andR.sub.2 is methyl or ethyl;and non-toxic, physiologically acceptable salts thereof formed with an inorganic or organic base. The compounds as well as their salts are useful as sweetening agents.
