  Fluorinated dual antithrombotic compounds based on 1,4-benzoxazine scaffold

  摘要：

  Fluorinated 3,4-dihydro-2H-1,4-benzoxazine derivatives possessing both thrombin inhibitory and glycoprotein IIb/IIIa receptor antagonistic activities were prepared as potential dual antithrombotic compounds. Fluorine scan (3-fluorobenzyl, 4-fluorobenzyl, 3,4-difluorobenzyl and 3,5-difluorobenzyl substituted compounds) was performed in order to obtain 6-(carboxymethyl)(3,4-difluorobenzyl) amino compound (9i) as the most potent compound with balanced dual activity (K-i(Thr) = 0.33 +/- 0.07 mu M, IC50(GP IIb/IIIa) = 1.1 +/- 0.6 mu M).

  Thrombin inhibitors with lipid peroxidation and lipoxygenase inhibitory activities

  摘要：

  Vascular oxidative stress, endothelial injury, and thrombosis are intertwined processes that display a synergistic pathological effect in many cardiovascular diseases. Antithrombotic therapy with anticoagulant and/or antiplatelet agents, combined with interventions against vascular oxidative stress and/or inflammation, both boosting endothelial antithrombotic potential, could display a synergistic action in the treatment of thrombosis. Of the compounds 10a-h and 11a-d, shown to possess thrombin inhibitory activity, 11a-d were found to display radical scavenging activity, 10a, 10d, and 10f were demonstrated to inhibit lipid peroxidation of linoleic acid, and 10b and 10h inhibited soybean lipoxygenase. The observed combination of thrombin inhibition with lipid peroxidation and/or lipoxygenase inhibitory activity makes compounds 10 and 11 interesting candidates for further investigations towards multiple antithrombotic drugs.

  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.
