Abstract:
Compounds of Formula I: ##STR1## are antagonists of the actions of leukotrienes. These compounds are useful as anti-asthmatic, anti-allergic, anti-inflammatory, and cytoprotective agents. They are also useful in treating angina, cerebral spasm, glomerular nephritis, hepatitis, endotoxemia, uveitis, and allograft rejection.
Abstract:
The invention encompasses compounds of Formula I useful in the treatment of diseases, including asthma, by raising the level of cyclic adenosine-3′,5′-monophosphate (cAMP) through the inhibition of phosphodiesterase IV (PDE IV). The invention also encompasses certain pharmaceutical compositions and methods for treatment of diseases by inhibition of PDE IV, resulting in an elevation of cAMP, comprising the use of compounds of Formula I.
