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
A Merriweather et al.
Molecular and biochemical parasitology, 116(2), 185-197 (2001-08-28)
The cuticle of parasitic nematodes consists primarily of a network of collagen molecules. The enzyme responsible for collagen maturation is prolyl 4-hydroxylase, making this enzyme a central activity in cuticle biosynthesis and a potentially important chemotherapeutic target. Adult and embryonic
