The method of claim 1, wherein R.sub.1 is H or C.sub.1-C.sub.6 aliphatic in the compound of formula I. 3. The method of claim 1, wherein R.sub.1 is H in the compound of formula I. 4. The method of claim 1, wherein two adjacent R.sub.2 in the compound of formula I together with the atoms to which they are attached form an optionally substituted carbocycle or an optionally substituted heterocycle. 5. The method of claim 1, wherein two adjacent R.sub.2 in the compound of formula I together with the atoms to which they are attached form an optionally substituted heterocycle. 6. The method of claim 1, wherein two adjacent R.sub.2 in the compound of formula I together with the atoms to which they are attached form an optionally substituted heterocycle selected from ##STR00850## 7. The method of claim 1, wherein two adjacent R.sub.2 in the compound of formula I together with the atoms to which they are attached form an optionally substituted heterocycle selected from ##STR00851## 8. The method of claim 1, wherein two adjacent R.sub.2 in the compound of formula I together with the atoms to which they are attached form ##STR00852## 9. The method of claim 1, wherein ring A in the compound of formula I is selected from ##STR00853## 10. The method of claim 1, wherein ring A in the compound of formula I is ##STR00854## 11. The method of claim 1, wherein 1 R.sub.3 in the compound of formula I is halo. 12. The method of claim 1, wherein 1 R.sub.3 in the compound of formula I is F. 13. The method of claim 1, wherein R'.sub.3 and an adjacent R.sub.3 in the compound of formula I together with the atoms to which they are attached form an optionally substituted heterocycle. 14. The method of claim 1, wherein R'.sub.3 and an adjacent R.sub.3 in the compound of formula I together with the atoms to which they are attached form an optionally substituted 3 to 7 membered heterocycle in which one or more of the ring atoms is N, O, S, or combination thereof. 15. The method of claim 1, wherein R'.sub.3 and an adjacent R.sub.3 together with the atoms to which they are attached form an optionally substituted 7 membered heterocycle in which one or more of the ring atoms is N, O, S, or combination thereof. 16. The method of claim 1, wherein the compound of formula I is administered as a pharmaceutical composition additionally comprising a pharmaceutically acceptable carrier or adjuvant. 17. The method of claim 16, wherein the composition comprises an additional agent selected from a mucolytic agent, bronchodialator, an anti-biotic, an anti-infective agent, an anti-inflammatory agent, CFTR modulator, or a nutritional agent. 18. A method of treating or lessening the severity of a disease in a patient, wherein the disease is selected from cystic fibrosis, hereditary emphysema, chronic obstructive pulmonary disease (COPD), and dry-eye disease, comprising administering to the patient a compound of claim 1. 19. The method of claim 18, wherein the disease is selected from cystic fibrosis, hereditary emphysema, and COPD. 20. The method of claim 18, wherein the disease is cystic fibrosis. 21. The method of claim 20, wherein the patient has a defective gene that causes a deletion of phenylalanine at position 508 of the CFTR amino acid sequence. 22. The method of claim 20, wherein the patient possesses a cystic fibrosis transmembrane receptor (CFTR) with a homozygous .DELTA.F508 mutation. 23. The method of claim 20, wherein the patient possesses a cystic fibrosis transmembrane receptor (CFTR) with homozygous G551D mutation. |
