Compounds having beta2 adrenergic receptor agonist and muscarinic receptor antagonist activity

The invention is directed to compounds of formula I: wherein R1, R2, R3, R4, R5, R6, R7a, R7b, W, G1, G2, a, b, c, d and m are as defined in the specification, or a pharmaceutically acceptable salt or solvate or stereoisomer thereof. The invention is also directed to pharmaceutical compositions comprising such compounds; methods of using such compounds; and process and intermediates for preparing such compounds.

Biphenyl derivatives

This invention provides biphenyl derivatives of formula I: wherein R1, R2, R3, R4, R5, R6, R7, W, a, b and c are as defined in the specification, or a pharmaceutically acceptable salt or solvate or stereoisomer thereof. The biphenyl derivatives of this invention possess both β2 adrenergic receptor agonist and muscarinic receptor antagonist activity and therefore, such biphenyl derivatives are useful for treating pulmonary disorders, such as chronic obstructive pulmonary disease and asthma.
