  • Patent number: 5589486
    Abstract: 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.

  • Patent number: 4831194
    Abstract: The invention relates to a new process for the preparation of aminodiaryl sulfoxide derivatives of the formula (I), ##STR1## wherein X is halogen, alkoxy having from 1 to 6 carbon atoms or a group --(N,R,R.sup.1), in which p1 R and R.sup.1 are hydrogen or alkyl having from 1 to 6 carbon atoms,R.sup.2 is hydrogen, halogen, alkyl having from 1 to 6 carbon atoms, alkoxy having from 1 to 6 carbon atoms or phenyl or phenylthio both optionally substituted by one or more identical or different halogen(s) and/or amino group(s),and acid addition salts thereof.The compounds of formula (I) are pharmaceutically active, in particular are potent anthelmintics, or can be used as active ingredients in pesticidal compositions. The invention therefore relates to pharmaceutical and pesticidal compositions containing compounds of formula (I) or salts thereof as active ingredient.Compounds of formula (I), in which the substituents are as defined above, but if X stands for a group --N(R,R.sup.1) in which R and R.sup.
