Development, synthesis, and biological evaluation of (-)-trans-(2S,5S)-2-[3-[(2-oxopropyl)sulfonyl]-4-n-propoxy-5-(3-hydroxypropoxy)-phenyl]-5-(3,4,5-trimethoxyphenyl)tetrahydrofuran, a potent orally active platelet-activating factor (PAF) antagonist and its water-soluble prodrug phosphate ester

(-)-trans-(2S,5S)-2-[3-[(2-Oxopropyl)sulfonyl]-4-n-propoxy-5-(3- hydroxypropoxy)phenyl]-5-(3,4,5-trimethoxyphenyl)tetrahydrofuran (10) is one of the most potent platelet-activating factor (PAF) antagonists in vitro and in vivo developed to date. This diaryltetrahydrofuran derivative evolved from modifications of MK 0287 which has been evaluated in clinical studies for asthma. Two structural modifications
(-)-反式-(2S,5S)-2- [3-[(2-氧丙基)磺酰基] -4-正丙氧基-5-(3-羟基丙氧基)苯基] -5-(3,4,5 -三甲氧基苯基)四氢呋喃(10)是迄今为止在体外和体内开发的最有效的血小板活化因子(PAF)拮抗剂之一。该二芳基四氢呋喃衍生物是从MK 0287的修饰衍生而来的,该修饰已在哮喘的临床研究中进行了评估。进行了MK 0287的两个结构修改:(1)将3'-[((羟乙基)磺酰基]基团修饰为β-酮基丙基磺酰基基团;(2)用3-羟丙基醚取代5'-甲基醚。 。化合物10有效且特异性地抑制[3H] -C18-PAF与人血小板膜(Ki 1.85 nM)和PMN膜(Ki 2.89 nM)的结合。体内,10抑制ED50分别为60微克/千克,口服和4微克/千克的静脉注射的雄性大鼠的PAF诱导的血浆外渗和升高的N-乙酰-β-D-氨基葡萄糖苷酶(NAGA)水平,并抑制PAF诱导的支气管
