Abstract:
:Several rationally designed analogs of 3-fluoro-2-oxo-3-phenylpropionic acid were chemically synthesized, and the reactions of the hydrate form of these compounds with 4-hydroxyphenylpyruvate dioxygenase from pig liver as inhibitors were examined. Compounds 14a and 14b were found to be potent competitive inhibitors of the enzyme with Ki values of 10 and 22 microM, respectively.
