Mechanism of action

SR123781A is a synthetic hexadecasaccharide comprising an antithrombin (AT) binding domain, a thrombin binding domain, and a neutral methylated hexasaccharide sequence, was obtained from glucose through a convergent synthesis. SR123781A showed high affinity for human AT and was a potent catalyst of its inhibitory effect with regard to factor Xa and thrombin.
