The Biochemical journal, 242(1), 163-169 (1987-02-15)
From the structure-activity relationships of known competitive inhibitors, coumalic acid (2-oxo-1,2H-pyran-5-carboxylic acid) was deduced to be a potential syncatalytic inhibitor for chick-embryo prolyl 4-hydroxylase. The compound caused time-dependent inactivation, the reaction rate being first-order. The inactivation constant was 0.094 min-1
