  • Publication number: 20030220347
    Abstract: The present invention provides 1,4 substituted piperazines, 1,4 substituted piperidines, and 1-substituted,4-alkylidenyl piperidines compounds. The compounds of the invention are dual acting molecules having both leukotriene inhibition properties as well as antihistaminergic properties. The compounds of the invention are useful for treating conditions in which there is likely to be a histamine and/or leukotriene component. These conditions include preferably asthma, seasonal and perennial allergic rhinitis, sinusitus, conjunctivitis, food allergy, scombroid poisoning, psoriasis, urticaria, pruritus, eczema, rheumatoid arthritis, inflammatory bowel disease, chronic obstructive pulmonary disease, thrombotic disease and otitis media. Also provided are methods of treating asthma and rhinitis by administering an effective asthma and rhinitis-relieving amount of the compounds to a subject in need thereof.

  • Patent number: 5003074
    Abstract: Compounds of formula I ##STR1## wherein R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are H, alkyl or aryl, m and n are 0 or 1, and A is a divalent organic radical which, with (CR.sup.1 R.sup.2).sub.m NF--SO.sub.2 (CR.sup.3 R.sup.4).sub.n groups, forms a 5- to 8-membered ring, are admirably suitable fluorinating agents for fluorinating carbon atoms, especially as stereospecific fluorinating agents, when the compounds contain a chiral carbon atom and are in optically active form. The compounds of formula I are prepared by reacting the corresponding silated sulfonamides, wherein the NF group is replaced by an N-SiR.sup.7 R.sup.8 R.sup.9 group and R.sup.7, R.sup.8 R.sup.9 are each independently C.sub.1 -C.sub.12 alkyl, cyclopentyl, cyclohexyl, benzyl or phenyl, with a fluorinating agent.
