  • Patent number: 5362721
    Abstract: The disclosed invention includes corticoid-17-alkylcarbonates substituted in the 17-position, a process for their preparation and pharmaceuticals containing them. These corticoid-17-alkylcarbonates have the following formula I ##STR1## where A is CHOH in any desired steric arrangement, C.dbd.O or CH.sub.2 ; Y is H, F, or Cl; Z is H, F or CH.sub.3 ; R(1) is O-acyl, carbonylalkyl, alkylsulfonate or arylsulfonate;R(2) is branched alkyl or (CH.sub.2).sub.2-4 --OCH.sub.3 andR(3) is H or methyl. They have excellent local and topical antiinflammatory action. They are distinguished by a particularly good ratio of local to systemic antiinflammatory activity and in some cases also show stronger local antiinflammatory activities than their isomeric corticoid-17-alkylcarbonates having a linear alkyl group in the 17-alkylcarbonate moiety.

  • Patent number: 4876354
    Abstract: Arylmethylazoles of the formula I ##STR1## in which Aryl is (substituted) phenyl or naphthyl;Z is CH or N;R.sup.1 and Q are H or alkyl;R.sup.2 is H, alk(en)yl or alkynyl;R.sup.3 and R.sup.4 are H, alkyl or other hydrocarbons; orR.sup.3 and R.sup.4 together are a --(CH.sub.2).sub.2-11 chain or a bridged --(CH.sub.2).sub.4-5 chain, and their acid addition salts, stereoisomers and optically active enantiomers possess outstanding antimycotic and antidepressant activity.They are obtained, inter alia, from arylmethylazoles II ##STR2## which are reacted with a strong base and then with a carbonyl compound III O.dbd.CR.sup.3 R.sup.4 ; thereafter, the product is reacted with the protic acid or with an alkyl halide IV R.sup.2 Hal.If desired, the products are converted to the acid addition salts, or the stereoisomers or optically active enantiomers are resolved.

  • Patent number: 4459225
    Abstract: New peptide amides of the formula IH--Tyr--D--Lys(For)--Gly--X (I)whereinFor is formyl,X is alkylamino, dehydro-Phe or Phe-alkylamido having up to 6 carbon atoms in the alkyl moiety, which moiety may be substituted by hydroxy and/or phenyl, Phe-cycloalkylamide or Phe-cycloalkylene amide having up to 8 carbon atoms in the cycloalkyl or cyclalkylene moiety, 1 to 2 CH.sub.2 groups being optionally replaced by --NH--, --O--, --S-- or --CO--, Phe-alkylene-cycloalkylamide having from 5 to 6 ring carbon atoms, which amide may be substituted by carbonamido,N-alkylcarbonamido or alkyl and 1 carbon atom whereof may be replaced by nitrogen, Phe-endo- or exo-norbornylamide or Phe-thiazolamide or Phe-thiazolidine-carboxylic acid amide, which may be substituted by 1 to 4 methyl groups each,and process for their manufacture are disclosed. These peptide amides are distinguished by an analgetic activity and suppress the motility of the ileum of the guinea pig.
