摘要:
The invention relates to new 2-pyridine-thiol derivatives of the formula (I), ##STR1## wherein R is hydrogen or alkyl having from 1 to 4 carbon atoms,Z is phenyl optionally substituted by one or more halogen atoms and/or alkyl groups having from 1 to 4 carbon atoms,R.sup.1 and R.sup.2 each independently represents hydrogen, alkyl having from 1 to 4 carbon atoms, alkylphenyl having from 1 to 4 carbon atoms in the alkyl moiety or an ##STR2## group, in which R has the same meaning as defined above, and the substituent ##STR3## is attached to the pyridine ring in the position 3 or 4, with the proviso that if R.sup.1 and R.sup.2 are both methyl and Z is 4-chlorophenyl, R is other than hydrogen, and acid addition salts thereof.The invention further relates to processes for the preparation of the above compounds and to pharmaceutical compositions containing them as active ingredient.The compounds are pharmaceutically active, in particular show cytoprotective activity.
摘要:
The compound N-{2-[(3-benzoyl-1-pyridyl)-thio]-ethyl}-N'-cyano-S-methyl-isothiourea and pharmaceutically acceptable acid addition salts thereof are disclosed as well as pharmaceutical compositions containing same and a method of treatment employing same. The compound or its acid addition salts are effective in treating gastric oedema and thus are useful in ulcer therapy.
摘要:
New intermediate compounds of the formula (I) are disclosed ##STR1## wherein R is hydrogen or C.sub.1 to C.sub.4 alkyl;Z is phenyl optionally substituted by one or more halogen atoms and/or alkyl groups having 1 to 4 carbon atoms; andD is hydroxy, mesyloxy, p-tosyloxy, or halogen; or pharmaceutically acceptable acid addition salt thereof. The compounds of the Formula (I) are intermediates in the preparation of new compounds having anti-ulcer activity.
摘要:
Ulcer production in animals is prevented during prolonged antiphlogistic treatment with ulcerogenic quantities of indomethacin by using it in a composition of 1 part of indomethacin to 7.5 to 25 parts, preferably 10 parts by weight of a salicylate. Indomethacin is the most potent ulcerating compound among approved non-steroid antiinflammatory agents.
摘要:
Ulcer production in animals is prevented during prolonged antiphlogistic treatment with ulcerogenic quantities of phenylbutazone by using it in a composition of 1 part of antiphlogistic to 0.2 to 50 parts by weight of alkali metal salicylate.
摘要:
The present invention relates to novel optically active or racemic tetrahydro-1,2,4-oxadiazine-5-thione derivatives of the formula ##STR1## methods for their preparation, pharmaceutical compositions comprising the said compounds as active ingredients and a method for the anticonvulsive treatment of mammals, especially human beings.The compounds of the formula I have as good activity as diphenyl hydantoine but their toxicity is much lower.
