Using the isoxazoline as a common structural feature, three series of glycoprotein IIb/IIIa receptor antagonists were evaluated, culminating in the discovery of XR299 (30). In an in vitro assay of platelet inhibition, XR299 had an IC50 of 0.24 microM and was a potent antiplatelet agent when dosed intravenously in a canine model. It was shown through X-ray studies of the cinchonidine salt 49 that the
使用异恶唑啉作为共同的结构特征,评估了三个系列的糖蛋白IIb / IIIa受体拮抗剂,最终发现了XR299(30)。在体外血小板抑制试验中,XR299在犬模型中静脉内给药时的IC50为0.24 microM,是一种有效的抗血小板药。通过辛可尼丁盐49的X射线研究表明,该受体需要5(R)-立体化学才能获得高效力。XR299,XR300(29)的乙酯前药在狗中具有口服活性。
