Abstract

A synthetic method for a series of new coumarin conjugates was developed. Their structures and physicochemical properties were determined by modern spectral methods (IR, NMR, ESI-MS). The anticoagulant activity was studied in vivo by determining the prothrombin time (PT). Compounds 4a (PT = 10.88 ± 0.56 sec) and 4b (13.10 ± 3.56 sec) were the most active and comparable to the reference drug warfarin (7.97 ± 1.93 sec).
