The invention relates to novel N-hydroxy-substituted 1,2,3,6-tetrahydropyridine and piperidine derivatives of the formula ##STR1## wherein A, B, D, E, G, I and R are as defined in the specification, m is 0, 1 or 2, with the proviso that:m is 0 or 2, or both G and I are hydrogen, when A is benzyl or halogen-monosubstituted benzyl group; andm is 1, when A is 2-picolyl, as well as their pharmaceutically acceptable acid addition salts. The compounds of formula (I) are useful for enhancing the tolerance of mammals (including man) against hypoxic and/or ischaemic states as well as for treating the degenerative and functional disturbances arising from hypoxic and/or ischaemic results.
摘要:
The present invention relates to novel 1,2,3,6-tetrahydropyridine derivatives of the general formula (I) ##STR1## wherein R stands for hydrogen or an alkyl group,X stands for an unsubstituted phenyl or benzyl group or for a phenyl or benzyl group substituted with a halogen atom,Y stands for hydrogen or halogen or a trifluoro-methyl groupas well as enantiomers acid addition salts thereof.The invention further extends to pharmaceutical compositions containing said compounds as active ingredient mainly for improving cerebral blood circulation and antihypoxic activity. The 1,2,3,6-tetrahydropyridine derivatives of the general formula (I) are prepared by treating an oxo derivative of the general formula (II) ##STR2## wherein R, X and Y are as given above in an organic solvent by a reducing agent and reacting the obtained 1,2,3,6-tetrahydropyridine derivative of the general formula (I), wherein R, X and Y are as given above, with a mineral or organic acid and converting the same, if desired, to an acid addition salt.
摘要:
The invention relates to novel 15-nitro-2.beta.,3.beta.-dihydro- and 15-nitro-2.beta.,3.beta.,6,7-tetrahydrotabersonine derivatives of the formula (I), ##STR1## wherein R.sup.1 stands for hydrogen;R.sup.2 stands for hydrogen or a C.sub.1-6 alkyl group; and the symbol represents a single or double bond as well as their salts.The invention further relates to pharmaceutical compositions containing the above compounds as well as a process for the preparation of the above compounds of formula (I) and of the pharmaceutical compositions.The compounds of formula (I) exert a reducing or inhibitory effect on cerebral edema and show antihypoxic properties. Thus, they are useful for the prevention or treatment of brain injuries of various origin induced by hypoxia of the brain.
摘要:
The invention relates to novel spiro[2H-1-benzopyran-2,4'-piperidine]-4(3H)-one derivatives of formula (I), ##STR1## wherein R stands for halogen, nitro group or a straight or branched chain C.sub.1-6 alkyl group, and their acid addition salts, as well as their quaternary salts of formula (Ia) ##STR2## wherein R and R' are the same or different and are identical to the meaning of said (above) R or can mean also hydrogen; and Z represents one equivalent of an anion. The compounds of formulas (I) and (Ia) exert an improving effect on dementias of various pathological origin and accompanying symptoms thereof. Furthermore, the invention relates to a process for the preparation of compounds of formulas (I) and (Ia); to pharmaceutical compositions containing as active gents the above compounds of formulas (I) and (Ia); and to a method of treatment.
摘要:
The invention relates to fused heterocyclic compounds with ring junction nitrogen atom of the formula: ##STR1## wherein Q stands for 2-indolizinyl, 2-imidazo[1,2-a]pyridinyl, 2-imidazo[1,2-a]pyrimidinyl, 6-(2,3-dihydroimidazo[2,1-b]thiazol)-yl or 6-imidazo[2,1-b]thiazolyl group; and n is an integer from 2 to 4, as well as therapeutically useful salts thereof. The invention further relates to pharmaceutical compositions containing these compounds as well as a process for the preparation of the above compounds and compositions. The compounds of formula (I) exhibit mainly antipsychotic effects so the invention relates also to a method of treatment of schizophrenia, organic mental disorders, affective disorders, anxiety and personality disorders.

摘要:
A needle guard assembly is provided for mounting to the hub of a needle assembly. The needle guard assembly includes a guide that is engageable on the hub. An elongate U-shaped cover is hingedly mounted to the guide and can be rotated from a first position where the needle cannula is substantially surrounded by the U-shaped walls of the cover into a second position where the needle cannula is exposed for use. The needle guard assembly further includes a slide that is slidably engaged in the guide and movable from a first position where the slide cooperatively engages the cover for completely surrounding the needle cannula to a second position where the slide is spaced proximally from the cover, thereby permitting the cover to rotate into its second position.
