  3,4-Dihydro-2H-1,4-benzoxazine Derivatives Combining Thrombin Inhibitory and Glycoprotein IIb/IIIa Receptor Antagonistic Activity as a Novel Class of Antithrombotic Compounds with Dual Function

  摘要：

  3,4-Dihydro-2H-1,4-benzoxazine derivatives possessing both thrombin inhibitory and glycoprotein IIb/IIIa (GPIIb/IIIa) receptor antagonistic activities were obtained by combining mimetics of the D-Phe-Pro-Arg pharmacophore of thrombin inhibitors and the Arg-Gly-Asp pharmacophor of GPIIb/IIIa receptor antagonists in the same low molecular weight peptidomimetic compound. Systematic variation of the position of substituents around the 3,4-dihydro-2H-1,4-benzoxazine nucleus, the distance between the carboxylate and amidine moieties, together with additional substituents to fill the thrombin S-2 and S-3 pockets resulted in compounds displaying submicromolar inhibition constants (K-i) for thrombin and submicromolar IC50 for inhibition of binding of fibrinogen to platelet GPIIb/IIIa receptor. Some of these compounds, such as 17a, 17b, 17d, and 17h possessing a well balanced activity at both targets, are a good starting point for further optimization. Incorporation of anticoagulant and platelet antiaggregatory activity in the same molecule constitutes a promising approach toward novel antithrombotic agents.
