ABSTRACT:
There are described compounds of formula ##STR1## in which n is 0, 1 or 2, R.sup.1 is a hydrocarbyl group optionally substituted with an optionally substituted phenyl group and containing from 5 to 30 carbon atoms, R.sup.2 is optionally substituted phenyl or C.sub.1-10 alkyl optionally substituted by one or more substituents selected from optionally protected hydroxyl, optionally protected carboxyl, nitrile, optionally protected tetrazolyl, --COR.sup.6 where R.sup.6 is C.sub.1-4 alkyl, C.sub.1-4 alkoxy, an optionally protected amino acid residue or --NR.sub.2.sup.7 where each R.sup.7 is hydrogen or C.sub.1-4 alkyl, and --NHR.sup.8 where R.sup.8 is hydrogen, a protecting group, an optionally protected amino acid residue, C.sub.1-4 alkyl or --COR.sup.9 where R.sup.9 is C.sub.1-4 alkyl or C.sub.1-4 alkoxy, and R.sup.3, R.sup.4 and R.sup.5 are each selected from hydrogen, carboxyl, C.sub.2-5 alkoxycarbonyl, C.sub.1-4 alkyl, C.sub.1-4 alkoxy, hydroxyl, optionally protected tetrazolyl, halo, trifluoromethyl, nitrile, nitro and --CONR.sub.2.sup.10 where each R.sup.10 is hydrogen or C.sub.1-4 alkyl; and salts thereof. The compounds are leukotriene antagonists.
