摘要:
Hydroximic acid derivatives possess anti-ischemic effects, and therefore, they are useful for treating ischemic states and diseases, such as myocardial ischemia (which may be induced by occlusion of coronary arteries). These derivatives include compounds of formula (I): ##STR1## wherein: X represents a halogen; Z represents an aromatic group, a pyridinyl group, a picolyl group, or a lutidyl group; and R represents an --A--N(R.sub.1)R.sub.2 group, wherein:R.sub.1 and R.sub.2 represent, independently from each other, hydrogen or an alkyl group;or R.sub.1 and R.sub.2, together with the adjacent nitrogen atom, form a 5- to 7-membered,saturated heterocyclic group optionally containing an additional nitrogen, oxygen,or sulfur atom, the heterocyclic group optionally being substituted by at least one alkyl group; andA represents a straight or branched chain alkylene group, as well as pharmaceutically acceptable acid addition salts thereof. The invention further relates to processes for preparing the above noted compounds, and pharmaceutical compositions containing these compounds or their pharmaceutically acceptable acid addition salts as an active ingredient. Additionally, the invention relates to intermediate compounds of formula II used in preparing the compounds of formula I. Formula II is as follows: ##STR2## In formula II, the variables Z and R have the same definitions provided above.
摘要:
The present invention provides novel hydroxylamine derivatives represented by the general formula: wherein:X is O, --NH, or a group of formula NR', wherein R and R' are independently selected from alkyl, cycloalkyl, phenylalkyl, phenyl optionally substituted with halo, haloalkyl,alkyl, alkoxy or nitro; and a N-containing heterocyclic ring;R.sup.1 is H or alkanoyl,R.sup.2 is H or hydroxy optionally acylated with alkanoyl, andR.sup.3 is a group of the formula --NR.sup.4 R.sup.5 wherein R.sup.4 and R.sup.5 are independently selected fromH, alkyl, and a group of the formula --CO--NH--R wherein R is as defined above, orwherein R.sup.4 and R.sup.5 when taken together form a 5- to 7-membered heterocyclic ring which may optionally contain one additional hetero atom selected from nitrogen, oxygen and sulfur and which is optionally substituted with alkyl or phenylalkyl.Also provided are pharmaceutically acceptable acid addition salts of the compounds defined above, as well as pharmaceutical compositions containing the compounds or their acid addition salts as active ingredients. The compounds of the invention have been shown to have anti-ischemic effects.

The invention relates to a method of treating or preventing illnesses resulting from damaged endothelial cells, wherein the method comprises administering to a patient a product comprising hydroxylamine derivatives of the general formulae (I) ##STR1## with the proviso that in the compounds of general formula (I) when X comprises a --NR.sup.3 R.sup.4 group and Y comprises a hydroxyl group, the X group is condensed with the Y substituent to form an intramolecular ring represented by general formula (Ill) ##STR2##
摘要:
The invention relates to racemic or optically active 1,3,4-benzotriazepin-5(4H)-one derivatives, a process for the preparation thereof, pharmaceutical compositions comprising the same, to the use of the said compounds for the treatment of diseases and for the preparation of pharmaceutical compositions containing the said compounds as active agent.The new compounds according to the invention correspond to the general formula (I), ##STR1## wherein R.sup.1 represents hydrogen or straight or branched chain C.sub.1-4 alkyl optionally carrying a pyridyl or a phenyl substituent;R.sup.2 stands for cyanoimino;R.sup.3 denotes hydrogen or straight or branched chain C.sub.1-4 alkyl;R.sup.4 stands for C.sub.1-4 alkyl; andthe dotted line does not represent a valency bond; orR.sup.2 stands for a group of the formula R.sup.9 R.sup.10 N, whereinR.sup.9 and R.sup.10 are independently hydrogen or straight or branched chain C.sub.1-10 alkyl, orR.sup.9 R.sup.10 N together form a 5- to 7-membered heterocyclic group; orR.sup.9 R.sup.10 N together form a group of the formula N.dbd.C(NR.sup.12 R.sup.13)NH.sub.2, wherein R.sup.12 and R.sup.13 are independently hydrogen or straight or branched chain C.sub.1-10 alkyl, orNR.sup.12 R.sup.13 together form a 5- to 7-membered heterocyclic group;R.sup.4 stands for C.sub.1-4 alkyl; andthe dotted line represents a valency bond, consequently substituent R.sup.1 is missing;with the proviso that if R.sup.9 and R.sup.10 are the same, they are other than hydrogen.The 1,3,4-benzotriazepin-5(4H)-one derivatives of the general formula (I) affect the circulatory system and possess antianginal, antihypertensive and peripheral vasodilating effects.
