Compounds 4 and 10a–i are single enantiomers with the S absolute configuration. ND = not determined.
Synthetic method used (A, B, or other).
Single testing dose was 300 mg/kg, ip. The effect is presented as the number of animals responding out of the total number of animals tested, except for any ED50 values.
Oral dose of 100 mg/kg, unless otherwise noted. The effect is presented as the number of animals responding out of the total number of animals tested.
IC50 values for the inhibition of human CA-II were determined in house by using a CO2 hydration assay (ref 10a–d), unless otherwise noted. The number of independent experiments (N) is one unless indicated otherwise; N > 1 is given in parentheses.
95% confidence interval: 86.6–139.
Oral dose of 300 mg/kg.
See text for information on this other (non-A/non-B) method.
Structure is equivalent to 10 with G = H.
