摘要:
Novel cystine derivatives having the structural formula (I): ##STR1## wherein R is benzyloxycarbonyl or tosyl, and the pharmaceutically acceptable acid addition salts thereof, are effective expectorants and antitussives, and are also effective for the liquescence of respiratory tract fluids.
摘要:
The .omega.-[4-(2-pyridyl)-piperazino]-alkanoylanilide compounds having the structural formula (I): ##STR1## wherein n is 1, 2 or 3, each of R, R.sub.1, R.sub.2 R.sub.3, and R.sub.4 is independently hydrogen, halogen, alkyl, alkoxy, OH, NH.sub.2, CF.sub.3, CN, alkylthio, 1-hydroxyalkyl, alkanoyl, NH.sub.2 CO, NH.sub.2 SO.sub.2, alkoxycarbonyl, alkylsulfonyl, benzyloxy, alkanoylamino, NH.sub.2 CONH, 3-phenylureido, 3-alkylureido or alkoxyoxalylamino, R.sub.5 is hydrogen or alkyl, and R.sub.6 is hydrogen or alkoxy, and the pharmaceutically acceptable salts thereof, are effective antianaphylactics, antibronchospastics, antihistaminics, sedatives, analgesics, antiserotonics and blood-pressure-lowering agents.
摘要:
Novel 3-methylflavone-8-carboxylates having the structural formula (I): ##STR1## wherein Z is N-methylpiperidinyl, tropinyl or quinuclidinyl, or a group having the structural formula (II): ##STR2## in which n is 0 or 1, R is hydrogen or alkyl having from 1 to 4 carbon atoms, or phenyl, R.sub.1 is hydrogen or alkyl having from 1 to 4 carbon atoms, R.sub.2 is hydrogen or hydroxy, and further wherein R, R.sub.1 and R.sub.2 may together form, with the carbon atoms from which they depend, a cycloalkyl ring having from 4 to 6 carbon atoms, and R.sub.3 is hydrogen or alkyl having from 1 to 4 carbon atoms, with the proviso that R, R.sub.1, R.sub.2 and R.sub.3 cannot at the same time all be hydrogen, and the pharmaceutically acceptable salts thereof, are effective smooth muscle relaxants, calcium blockers, anaesthetics and anti-inflammatories.
摘要:
There are provided 2,4-dichloro-4'-phenyl-.alpha.-(N-imidazolyl-methyl)-dibenzyl ether, 2,4-dichloro-4'-phenylthio-.alpha.-(N-imidazolyl-methyl)-dibenzyl ether and pharmaceutically acceptable acid addition salts thereof. These compounds show activity against some fungi, yeasts and gram positive aerobic and anaerobic bacteria. The new compounds can be prepared by condensing 1-(2',4'-dichlorophenyl)-2-(N-imidazolyl)-ethanol with 4-chloromethyl-biphenyl, 4-bromomethyl-biphenyl, 1-phenylthio-4-chloromethyl-benzene or 1-phenylthio-4-bromomethyl-benzene in a solvent, most preferably dimethylsulphoxide.
摘要:
Solid dosage form for the controlled release of flavoxate hydrochloride is described. The dosage form includes a matrix allowing gradual release of the flavoxate hydrochloride contained within it, a suitable binder which limits the dimensions of the finished solid dosage form, and an acidifying agent which ensures stability of the flavoxate hydrochloride with time and improves its release profile by making it independent of pH.
