ABSTRACT
|
|
|
| |
|
Human carbonic anhydrases (CAs) are well studied targets for the development of
inhibitors for pharmaceutical applications. The crystal structure of human CA II
has been determined in complex with two CA inhibitors (CAIs) containing
conventional sulfonamide and thiadiazole moieties separated by a -CF2- or
-CHNH2- spacer group. The structures presented here reveal that these spacer
groups allow novel binding modes for the thiadiazole moiety compared with
conventional CAIs.
