Low-molecular-weight fucosylated glycosaminoglycan and its oligosaccharides from sea cucumber as novel anticoagulants: A review
2020
Abstract Antithrombotic drugs have some side effects, such as risk of serious bleeding. Development of antithrombotic drugs that inhibit components of the intrinsic coagulation pathway and have a low risk of causing bleeding has recently been a focus of research. Fucosylated glycosaminoglycan (FG), also named as fucosylated chondroitin sulfate (FCS), has potent anticoagulant activity and inhibits intrinsic factor tenase (FXase) complex. Low-molecular-weight FG (LFG) and its oligosaccharides show characteristics of anticoagulant and antithrombotic activities with negligible side effects, such as activation of human FXII, induction of platelet aggregation, and especially, the risk of serious bleeding. They are potential new anticoagulant drugs and have been extensively studied in recent years. This review presents recent findings regarding the preparation, structural analysis, pharmacological activity, and structure–activity relationships of LFG and its derived oligosaccharides, so as to provide a reference for the development of new anticoagulants with low side effects.
