    摘要:
    恩他卡朋是儿茶酚-O-甲基转移酶(COMT)的新型抑制剂,可作为左旋多巴疗法的辅助治疗帕金森氏病。但是,口服他卡朋的生物利用度相对较低(29-46%)。在这项研究中,我们制备了更多的恩他卡朋的亲脂性酰基酯和酰氧基酰基酯,酰氧基烷基醚和烷氧基羰基酯,我们将它们评估为增强恩他卡朋口服生物利用度的潜在前药。所有衍生物均符合前药标准,并在人血清中体外释放他卡酮。在大鼠中进一步研究了entacapone的单新戊酰基(1a)和二新戊酰基(1b)酯的口服生物利用度。1b的亲脂性较高(在pH 7.4时,log Papp 4.0),但口服生物利用度较低(F = 0.6%),最可能是由于其低水溶性。在pH 7.4时,entacapone(1a)的单新戊酰基酯的亲脂性(log Papp 0.80)比entacapone(log Papp 0.18)高,同时保持水溶性等于entacapone。但是,与母体药物恩他

    Gradient index optical materials are formed by drop by drop dispensing of nanoparticle/monomer suspensions. Refractive index variations are defined by nanoparticle concentrations that can vary in three dimensions. Droplets of differing compositions can be mixed, and droplets or layers or droplets are partially cross-linked by exposure to ultraviolet radiation prior to dispensing additional droplets. Gradient index optical elements such as lenses, prisms, and waveguides can be formed in flexible polymer layers.
    渐变折射率光学材料是通过滴滴分配纳米颗粒/单体悬浮液形成的。折射率变化由纳米颗粒浓度在三个维度上变化定义。不同成分的液滴可以混合,液滴或液滴层可以在分配额外液滴之前通过紫外线辐射部分交联。可以在柔性聚合物层中形成渐变折射率光学元件,如透镜、棱镜和波导。
