This invention provides biphenyl derivatives containing (i) a (biphenyl-2-yl)oxycarbonylamino- or (biphenyl-2-yl)aminocarbonylamino-substituted (2-7C)azacycloalkyl or (5-10C)azabicycloalkyl group; (ii) a substituted 2-(4-hydroxyphenyl)-2-hydroxyethylamino group; and a divalent hydrocarbon group, where each group is further defined and optionally substituted as described in the specification. The biphenyl derivatives of the invention possess both &bgr;
2
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.
