EP0106565B1 — Leukotriene antagonists, their production, and compositions containing them

USPTO Abstract

Compounds of the formulae: <CHEM> and their pharmaceutically acceptable (including acid-addition) salts, which are novel, are antagonists of leukotrienes of C4, D4 and E4, the slow reacting substance of anaphylaxis. They can be made into pharmaceutical compositions by incorporating them in a pharmaceutical carrier. In the formulae, each R is H, OH, SH C1 6 alkyl C2 6 alkenyl, CF3, C1 6 alkoxy, C1 6 alkylthio, benzyl, phenethyl, halogen, amino, N(R4)2, COOR4 or CH2OR4 where R4 is H or C1 6 alkyl, formyl, CN, CF3S or NO2; each R min is R4; OR4; COOR4; N(R4)2; SR4; CH2OR4 or CHO; or together R min and R min are O, CH2 or <CHEM> Y min is sulfur, sulfoxide, sulfone, @ = NR11, = NR12, = N - CO - R13, - N - CN, CH2 or C = 0 where R11 is H, C1-4 alkyl, C1 4 alkanoyl, phenylsulfonyl or p-toluenesulfonyl, R12 is H or C1-4 alkyl and R13 is C1-4 alkyl or C1-4 alkoxy; Y is of the type defined for Y min or oxygen; each R1 is hydrogen C1-3 alkyl; each m is 0 or an integer from 1 to 6; <CHEM> where each R6 is H or C1-4 alkyl; each R7 is H, OH or C1-4 alkyl; and each R8 is H or C1-4 alkyl and is absent when the two indicated carbons are triply bonded; R5 is COOR4; CH2OH, CHO: tetrazole; NHSO2R14; CONHSO2R14; hydroxymethylketone; CN; CON(R7)2; a monocyclic or bicyclic heterocyclic ring containing an acidic hydroxyl group; or COOR15 where R15 is: <CHEM> where each s is independently 0-3, R6 is as defined above and R16 is (A) a monocyclic or bicyclic heterocyclic radical containing from 3 to 12 nuclear carbon atoms and 1 or 2 N heteroatoms or one N and one S heteratom, each ring in the heterocyclic radical being formed of 5 or 6 atoms, or (B) W-R17 where W is O, S or NH and R17 contains up to 21 carbon atoms and is (1) a hydrocarbon radical or (2) an acyl radical or an organic acyclic or monocyclic carboxylic acid containing not more than 1 heteroatom in the ring; each of r and q is 0-20 but r + q does not exceed 20; and p is 0 or 1; R3 is C1-6 alkyl or C3-6 alkenyl; R9 is C1-6 alkyl, C1 6 alkoxy or (CH2)rR5, where r and R5 are as defined above; and R10 is H, C1-6 alkyl; R4CO- or R4OCH2, where R4 is as defined above and R14 is OH, C1-6 alkoxy, C1-6 acyl, phenyl, phenyl having C1-3 alkyl or C1-3 alkoxy substitution, halogen, halogenated alkyl, carboxy, cyano or formyl.
