NOVEL ORGANIC COMPOUNDS AND THEIR PHARMACEUTICAL USE There are described compounds of formula (I) in which n is 0, 1 or 2, R1 is a hydrocarbyl group optionally substituted with an optionally substituted phenyl group and containing from 5 to 30 carbon atoms, R2 is optionally substituted phenyl or C1-10alkyl optionally substituted by one or more substituents selected from optionally protected hydroxyl, optionally protected carboxyl, nitrile, optionally protected tetrazolyl, -COR6 where R6 is C1-4alkyl, C1-4alkoxy, an optionally protected amino acid residue or -NR? where each R7 is hydrogen or C1-4alkyl, and -NHR9 where R8 is hydrogen, a protecting group, an optionally protected amino acid residue, C1-4alkyl or -COR9 where R9 is C1-4alkyl or C1-4alkoxy, and R3, R4 and R5 are each selected from hydrogen, carboxyl, C2-5 alkoxycarbonyl, C1-4alkyl, C1-4alkoxy, hydroxyl, optionally protected tetrazolyl, halo, trifluoromethyl, nitrile, nitro and -CONR? where each R10 is hydrogen or C1-4 alkyl; and salts thereof. The compounds are leukotriene antagonists. |
