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.

Figure 2 Interactions between HCA II and inhibitors. (a) BB3, (b) TDM. Hydrogen bonds are indicated by dashed red lines (distances given in Å), side chains are as labeled and the Zn atom is shown as a black sphere. Figures were generated and rendered with BobScript and Raster3D, respectively (Esnouf, 1999[Esnouf, R. M. (1999). Acta Cryst. D55, 938-940.]; Merritt & Bacon, 1997[Merritt, E. A. & Bacon, D. J.
