Publication Abstract from PubMedThe atomic-resolution crystal structures of human carbonic anhydrases I and II complexed with "two-prong" inhibitors are reported. Each inhibitor contains a benzenesulfonamide prong and a cupric iminodiacetate (IDA-Cu(2+)) prong separated by linkers of different lengths and compositions. The ionized NH(-) group of each benzenesulfonamide coordinates to the active site Zn(2+) ion; the IDA-Cu(2+) prong of the tightest-binding inhibitor, BR30, binds to H64 of CAII and H200 of CAI. This work provides the first evidence verifying the structural basis of nanomolar affinity measured for two-prong inhibitors targeting the carbonic anhydrases. Ultrahigh resolution crystal structures of human carbonic anhydrases I and II complexed with "two-prong" inhibitors reveal the molecular basis of high affinity.,Jude KM, Banerjee AL, Haldar MK, Manokaran S, Roy B, Mallik S, Srivastava DK, Christianson DW J Am Chem Soc. 2006 Mar 8;128(9):3011-8.
