A medicament for preventive and/or therapeutic treatment of a microbial infection having an activity of eliminating resistance of a microorganism with acquired resistance to an antimicrobial agent, which comprises as an active ingredient a compound represented by the following general formula (I), a physiologically acceptable salt thereof, or a hydrate thereof: wherein R1 and R2 independently represent hydrogen atom, a halogen atom, carboxyl group and the like; J1 represents a 5- or 6-membered heteroaromatic ring; W1 represents -CH=CH-, -C≡C-, -CH2CH2- and the like; A1 represents phenylene group, pyridinediyl group, furandiyl group and the like; G1 represents oxygen atom, carbonyl group, ethynyl group and the like; p represents an integer of from 0 to 3; G2 represents phenylene group, furandiyl group, tetrahydrofurandiyl group and the like; G3 represents -CH2- or single bond; m and n represent an integer of 0 or 1; and Q1 represents an acidic group.

Two series of compounds, N- sulfonamides and N- sulfonamides, were prepared as leukotriene D4 (LTD4) antagonists.In the phenyl series, N--trifluoromethanesulfonamide (Wy-48,252, 16) was the most potent inhibitor of LTD4-induced bronchoconstriction in the guinea pig.With an intragastric ID 50 of 0.1 mg/kg (2-h pretreatment), 16 was 300 times more potent than LY-171,883.Compound 16 also intragastrically inhibited ovalbumin-induced bronchoconstriction in the guinea pig with an ID 50 of 0.6mg/kg.In vitro against LTD4-induced contraction of isolated guinea pig trachea pretreated with indomethacin and L-cysteine, 16 produced a pKB value of 7.7.In the rat PMN assay 16 inhibited both 5-lipoxygenase and cyclooxygenase (IC 50's = 4.6 and 3.3 μM).In the naphthyl series, N-trifluoromethanesulfonamide (Wy-48,090, 47) in addition to potent LTD4 antagonist activity (on isolated guinea pig trachea 47 had a pKB value of 7.04) also had antiinflammatory activity (63percent inhibition at 50 mg/kg in the rat carrageenan paw edema assay and 34percent inhibition of TPA-induced inflammation at 1 mg/ear in the mouse ear edema model).Perhaps the antiinflammatory activity of 47 was due to its additional activity of inhibiting both 5-lipoxygenase and cyclooxygenase enzymes (IC 50's = 0.23 and 11.9 μM, respectively, in rat PMN).
