This invention relates to a compound of formula I: or a pharmaceutically acceptable salt thereof. Such compounds possess both muscarinic receptor antagonist and β 2 adrenergic receptor agonist activities. The invention also relates to pharmaceutical compositions comprising such compounds, processes and intermediates for preparing such compounds, and methods of using such compounds as bronchodilating agents to treat pulmonary disorders.
1. A method for treating a pulmonary disorder in a patient comprising administering to the patient biphenyl-2-ylcarbamic acid 1-(2-{[4-(4-{[(R)-2-hydroxy-2-(8-hydroxy-2-oxo-1,2-dihydroquinolin-5-yl)ethylamino]methyl}-phenylcarbamoyl)butyl]methylcarbamoyl}ethyl)piperidin-4-yl ester of formula:
or a pharmaceutically acceptable salt thereof.
2. A method for treating a pulmonary disorder in a patient comprising
(a) administering to the patient biphenyl-2-ylcarbamic acid 1-(2-{[4-(4-{[(R)-2-hydroxy-2-(8-hydroxy-2-oxo-1,2-dihydroquinolin-5-yl)ethylamino]methyl}-phenylcarbamoyl)butyl]methylcarbamoyl}ethyl)piperidin-4-yl ester of formula:
or a pharmaceutically acceptable salt thereof and
(b) administering to the patient a steroidal anti-inflammatory agent, or a pharmaceutically acceptable salt or solvate thereof;
wherein step (a) and (b) are conducted simultaneously or sequentially in any order.
3. The method of claim 1 or 2 , wherein the pulmonary disorder is chronic obstructive pulmonary disease.
4. The method of claim 1 or 2 , wherein the pulmonary disorder is asthma.
5. A method for producing bronchodilation in a mammal comprising administering to the mammal a bronchodilation-producing amount of biphenyl-2-ylcarbamic acid 1-(2-{[4-(4-{[(R)-2-hydroxy-2-(8-hydroxy-2-oxo-1,2-dihydroquinolin-5-yl)ethylamino]methyl}-phenylcarbamoyl)butyl]methylcarbamoyl}ethyl)piperidin-4-yl ester of formula:
or a pharmaceutically acceptable salt thereof.
6. The method of claim 5 , wherein the mammal is a human.
