from 4-nitroimidazole, others were derived from 1a through simple exchange reactions with the appropriate alcohols. The observed kinetics profiles and K(i) values suggest that the target compounds are competitive inhibitors that bind 6-9 orders of magnitude less tightly to the enzyme. Compounds 1c and 1d were the most active in the series with K(i)'s ranging from 12 to 15 microM.
