potentially due to high affinity for unactivated platelets. Isoxazolylsulfonamide 34b (DMP 802), a highly selective GPIIb/IIIa antagonist, demonstrated a prolonged duration of action after iv and po dosing and high affinity for resting and activated platelets. The prolonged antiplatelet profile of DMP 802 in dogs and the high affinity of DMP 802 for human platelets may be predictive of clinical utility as
异恶唑啉GPIIb / IIIa(αIIbbeta3)拮抗剂DMP 754(7)的α-氨基甲酸酯取代基的修饰导致了一系列α-磺酰胺和α-磺酰胺二氨基丙酸酯异恶唑啉基乙酰胺,被发现是体外血小板聚集的有效抑制剂。发现芳基和杂芳基-α-磺酰胺基团与(5R)-异恶唑啉(2S)-二氨基丙酸酯的立体化学相结合可在犬中显着延长抗血小板作用的持续时间,这可能是由于对未活化的血小板具有高亲和力。异恶唑基磺酰胺34b(DMP 802)是一种高度选择性的GPIIb / IIIa拮抗剂,在静脉和口服给药后表现出延长的作用时间,并且对静息和活化的血小板具有高亲和力。
