To enhance the potency, reduce the side effects and improve oral property of estradiol in estrogen replacement therapy (ERT), 6 novel estradiol–RGD octapeptide conjugates have been prepared. In an ovariectomized mouse osteoporotic model, at an oral dosage of 110.3 nmol/kg per day, their anti-osteoporosis activity was significantly higher than that of estradiol and estradiol–RGD tetrapeptide conjugates

(EN) A benzodiazepinedione derivative which acts as a nonpeptidyl platelet aggregation inhibitor is provided. This inhibitor potently inhibits fibrinogen binding to the GPIIbIIIa receptor and is provided in therapeutic compositions for the treatment of diseases for which blocking platelet aggregation is indicated. These nonpeptidyl inhibitors are provided in combination with thrombolytics and anticoagulants.(FR) Un dérivé de benzodiazépinedione intervient en tant qu'inhibiteur non peptidyle d'aggrégation des plaquettes. Il inhibe fortement la liaison des fibrinogènes au récepteur GPIIbIIIa et figure dans des compositions thérapeutiques relatives au traitement de maladies pour lesquelles il convient de bloquer l'aggrégation des plaquettes. Ces inhibiteurs non peptidyles sont combinés avec des thrombolytiques et des anticoagulants.
