Phenprocoumon

Phenprocoumon (CAS No.: 435-97-2) is a synthetic coumarin derivative broadly classified as a small molecule biochemical probe for hemostasis related biology and vitamin K dependent enzymatic regulation, and it is primarily used in biomedical research to interrogate vitamin K cycle control of coagulation factor maturation and related redox processes. Current evidence characterizes phenprocoumon as a vitamin K antagonist with inhibitory activity against vitamin K epoxide reductase complex function, with reported potency in low micromolar levels and overall pharmacological activity generally described from micromolar to sub micromolar ranges depending on assay format, substrate conditions, and species specific enzyme context. Mechanistically, it suppresses recycling of reduced vitamin K, thereby limiting gamma carboxylation of vitamin K dependent proteins and enabling pathway level studies of coagulation associated biosynthetic networks, post translational modification control, and systems pharmacology of anticoagulant response phenotypes in experimental settings. In life sciences workflows, it is commonly incorporated into in vitro enzyme and cell based assays, comparative profiling of vitamin K antagonists, resistance mechanism studies involving VKOR related determinants, and in vivo pharmacology models designed to evaluate coagulation biology or compound response variability under controlled laboratory conditions. As with other members of this research class, experimental concentrations or dosing regimens are selected according to specific model design, endpoint sensitivity, and study objectives in discovery or translational preclinical research contexts, and the material is intended strictly for laboratory research use and not for food, supplement, or any human use scenarios.
