Summary: | The invention relates to hydroximic acid derivatives of the general formula (I):wherein : X is halogen; Z is a pyridinyl or similar aromatic group; and R is alkyl or phenylalkyl group or an A-N(R 1)R 2 group and in this last group R 1 and R 2 are independently hydrogen or an alkyl group; or R 1 and R 2 form together with the adjacent nitrogen atom a 5...7 -member saturated heterocyclic group optionally comprising an additional nitrogen, oxygen or sulphur atom, the group being optionally substituted with an alkyl group; and A is a linear- or branched-chain alkylene group. The hydroximic acid derivatives of the formula (I) also includ the pharmaceutically acceptable acid addition salts thereof. The invention also relates to processes for the preparation of hydroximic acid derivatives of the general formula (I), to intermediates for carrying out one of the processes as well as to pharmaceutical compositions comprising as active ingredient the hydroximic acid derivatives of the general formula (I), used for the treatment of ischemic conditions and diseases in mammals, humans included.
Invenţia se referă la derivaţii de acid hidroximic cu formula generală (I):în care: X are semnificaţia unui halogen; Z are semnificaţia unei grupări aromatice, piridinil sau asemănătoare; şi R are semnificaţia unei grupări alchil, sau fenilalchil sau o grupare -A-N(R)Rşi în acestă ultimă grupare, Rşi Rau semnificaţia, independent unul de celălalt, a unui hidrogen sau a unei grupări alchil; sau Rşi Rformează împreună cu atomul de azot adiacent o grupare heterociclică saturată cu 5...7 membri, conţinând opţional un atom adiţional de azot, oxigen sau sulf, gruparea fiind opţional substituită cu o grupare alchil; şi A are semnificaţia unei grupări alchilen cu catenă liniară sau ramificată. Derivaţii de acid hidroximic cu formula generală (I) includ şi sărurile lor de adiţie acidă, acceptabile farmaceutic. De asemenea, invenţia se referă la procedee de obţinere a derivaţilor de acid hidroximic cu formula generală (I), la intermediari pentru realizarea unuia dintre procedee, precum şi la compoziţii farmaceutice care cuprind ca ingredient activ derivaţii de acid hidroximic cu formula generală (I), folosite pentru tratamentul stărilor şi bolilor ischemice, la mamifere, inclusiv la om. |
