effects against influenza virus. Crenatoside, a phenylethanoid glycoside from Pogostemon cablin Benth, which has been shown as a novel effective NA inhibitor previously, is considered as the leading compound for our further SARs studies. This work presented design, synthesis of novel crenatoside analogues from readily available d-Glucose and l-rhamnose in a convergent manner. Furthermore, their biological
已发现天然产物,尤其是衍生自TCMH的天然产物,对流感病毒具有抗病毒作用。Crenatoside,一种来自Pogostemon cablin Benth的苯乙类固醇糖苷,以前被证明是一种新型的有效NA抑制剂,被认为是我们进一步SAR研究的主要化合物。这项工作提出了从收敛的d-葡萄糖和1- r-鼠李糖中合成,设计新的番石榴苷类似物的方法。此外,还研究了它们的生物活性和SAR。特别是,化合物2 h对 NAs的IC 50值令人印象深刻,为27.77μg/ mL,其效力比领先化合物Crenatoside(IC 50)高3倍。 = 89.81μg/ mL)。这些结果有望证明它们具有治疗流感疾病的潜力。
