First Claim
1. A compound of formula:
- ##STR25## wherein;
Ar is an aryl or heteroaryl group that is optionally substituted with at least one group selected from the group consisting of halo, lower alkoxy, lower aryloxy, --C(O)N(OM)R4, A--B, cyano, or R3 ;
but when W is --A--B, Ar is substituted at least once with --C(O)N(OM)R4, and is optionally substituted with halo, lower alkoxy, lower aryloxy, A--B, cyano, or R3 ;
W is independently --C(O)N(OM)R4, or --A--B;
but when W is --A--B, Ar is substituted at least once with --C(O)N(OM)R4, and is optionally substituted with halo, lower alkoxy, lower aryloxy, A--B, cyano, or R3 ;
A is lower alkyl, lower alkenyl, lower alkynyl, alkaryl or aralkyl groups, wherein one or more carbons optionally can be replaced by O, N, or S;
(with valence completed with hydrogen or oxygen as necessary), provided --A-- does not form two adjacent heteroatoms;
B is selected from the group consisting of pyridylimidazole and benzimidazole, either of which is optionally substituted with R3 ;
M is hydrogen, a pharmaceutically acceptable cation, or a metabolically cleavable leaving group;
X is O, S, S(O), NR5, or CHR5 ;
R1 and R2 are independently hydrogen, lower alkyl;
halo lower alkyl, halo; and
--COOH; and
R3 and R4 are independently hydrogen or alkyl, alkenyl, alkynyl, aryl, aralkyl, alkaryl, C1-6 alkoxy-C1-10 alkyl, C1-6 alkylthio-C1-10 alkyl, heteroaryl, or heteroarylalkyl-;
R5 is hydrogen, lower alkyl, lower alkenyl, lower alkynyl, alkaryl, --AN(OM)C(O)N(R3)R4, --AN(R3)C(O)N(OM)R4, --AN(OM)C(O)R4, --AC(O)N(OM)R4, --AS(O)n R3, --AS(O)n CH2 C(O)R3, --AS(O)n CH2 CH(OH)R3, --AC(O)NHR3 ; and
wherein n is 0-2,or pharmaceutically acceptable salt thereof.

Abstract
Disubstituted tetrahydrofurans, tetrahydrothiophenes, pyrrolidines and cyclopentanes are disclosed that reduce the chemotaxis and respiratory burst leading to the formation of damaging oxygen radicals of polymorphonuclear leukocytes during an inflammatory or immune response. The compounds exhibit this biological activity by acting as PAF receptor antagonists, by inhibiting the enzyme 5-lipoxygenase, or by exhibiting dual activity, i. e., by acting as both a PAF receptor antagonist and inhibitor of 5-lipoxygenase.
A method to treat disorders mediated by PAF and/or leukotrienes is also disclosed, that includes administering an effective amount of one or more of the above-identified compounds or a pharmaceutically acceptable salt thereof, optionally in a pharmaceutically acceptable carrier.
