This invention is directed to certain physiologically active compounds of formula (I)
wherein
represents a bicyclic ring system, of about 10 to about 13 ring members, in which the ring
is an azaheterocycle, and the ring
represents an azaheteroaryl ring, or an optionally halo substituted benzene ring;
and N-oxides thereof, and their prodrugs, and pharmaceutically acceptable salts and solvates of the compounds of formula (I) and N-oxides thereof, and their prodrugs. Such compounds inhibit the production or physiological effects of TNF and inhibit cyclic AMP phosphodiesterase. The invention is also directed to pharmaceutical compositions comprising compounds of formula (I), their pharmaceutical use and methods for their preparation.
Sulfonyl derivatives represented by the following general formula (I): Q1-Q2-T1-Q3-SO2-QA and drugs containing the same (wherein Q1 is an optionally substituted, saturated or unsaturated, five- or six-membered cyclic hydrocarbon group, a five- or six-membered heterocyclic group, or the like; Q2 is a single band, oxygen, sulfur, C1-C6 alkylene or the like; QA is optionally substituted arylalkenyl, heteroarylalkenyl or the like; and T1 is carbonyl or the like). These compounds have potent FXa-inhibitory effects and promptly exert satisfactory and persistent antithrombotic effects through oral administration, thus being useful as anticoagulant agents little accompanied with side effects.
Many 2-[[(4-fluoroalkoxy-2-pyridyl)methyl]sulfinyl]-1H-benzimidazoles were synthesized and tested for antisecretory, antiulcer, and cytoprotective activities. Most of these compounds were superior to omeprazole in antisecretory and antiulcer potencies, and especially in protecting the gastric mucosa from ethanol-induced damage. Among these compounds 2-[[[3-methyl-4-(2, 2, 2-trifluoroethoxy)-2-pyridyl]methyl]sulfinyl]-1H-benzimidazole, AG-1749 (lansoprazole) (6f), was selected for further development and clinical evaluation.
The present invention provides a compound of the Formula I: wherein A is: and W, Y, X, R1, R2, R3, and R4 are as defined herein, or a pharmaceutically acceptable salt thereof, for use as an inhibitor of the EP4 receptor.
