1,3,5-Substituted indoles and indazoles have been studied as receptor antagonists of the peptidoleukotrienes. The best of these compounds generally had a methyl group at the N1 position, a [(cyclopentyloxy)carbonyl]amino or 2-cyclopentylacetamido or N'-cyclopentylureido group at the C-5 position, and an arysulfonyl amide group as part of the acidic chain at the C-3 position of the ring. Such compounds had in vitro dissociation constants K(B) in the range 10-9-10-11 M on guinea pig trachea against LTE4 as agonist and inhibition constants (K(i)) ≤ 10-9 M on guinea pig parenchymal membranes against [3H]LTD4. A number of compounds were orally effective at doses ≤1 mg/kg in blocking LTD4-induced 'dyspnea' in guinea pigs. Compound 45 [N-[4-[[5-[[cyclopentyloxy)carbonyl]amino]-1-methylindol-3-yl]methyl]- 3-methoxybenzoyl]-2-methyl]benzenesulfonamide, ICI 204,219; pK(B) = 9.67 ± 0.13, K(i) = 0.3 ± 0.03 nM, po ED50 = 0.3 mg/kg] is currently under clinical investigation for asthma. In the indole series, certain alkylsulfonyl amides possessing a 3-cyanobenzyl substituent at the N-1 position (60, 61) were produced that had K(B) ≤ 10-9 M on guinea pig trachea.

, (2008/06/13)
This invention provides a series of novel keto sulfones of formula I STR1 in which the group =A-- is selected from =C(Ra)-- and =N-- and the other radicals have the meanings defined in the following specification. The compounds of formula I are leukotriene antagonists. The invention also provides pharmaceutically acceptable salts of the formula I compounds; pharmaceutical compositions containing the formula I compound, or their salts, for use in the treatment of, for example, allergic or inflammatory diseases, or endotoxic or traumatic shock conditions; and processes for the manufacture of the formula I compounds, as well as intermediates for use in such manufacture.
