摘要:
The invention relates to new polycyclic compounds substituted on the A-ring. More particularly, the invention concerns new polycyclic compounds of the formula (I) ##STR1## wherein R.sup.1 is methoxy or halogen andR.sup.2 is hydrogen; orR.sup.1 is hydrogen andR.sup.2 is halogen and acid addition salts thereof.
摘要:
The invention relates to the new apovincaminol-3',4',5'-trimethoxy-benzoate and acid addition salts thereof. The new compound may be prepared by reacting apovincaminol or an acid addition salt thereof with 3,4,5-trimethoxy benzoic acid or a reactive derivative thereof capable of acylation and if desired converting the compound thus obtained into an acid addition salt. The new compound of the present invention can be used in therapy in the treatment of skin diseases attached to pathological cell proliferation and in the propylaxis of such diseases.
摘要:
The present invention relates to the compounds of the Formulae 1a and 1b and pharmaceutically acceptable acid addition salts thereof.The new 9-nitro-apovincaminol-3',4',5'-trimethoxybenzoate of the Formula 1a ##STR1## and the 11-nitro-apovincaminol-3',4',5'-trimethoxy-benzoate of the Formula 1b ##STR2## and pharmaceutically acceptable acid addition salts thereof can be prepared by nitrating the apovincaminol-3',4',5'-trimethoxy-benzoate of the Formula 11, ##STR3## if desired separating the mixture of the compounds of the Formulae 1a and 1b thus obtained into its components, if desired converting a compound of the Formula 1a or 1b thus obtained into pharmaceutically acceptable acid addition salts thereof.The new compounds of the present invention can be used in therapy in the treatment of psoriasis.
摘要:
The invention relates to the new 17,18-dehydro-apovincaminol-3',4',5'-trimethoxy-benzoate of formula (I) ##STR1## and acid addition salts thereof.
