oligosaccharides that is currently undergoing clinical evaluation in cancer patients. As well as its anticancer properties, 1 displays a number of other interesting biological activities. A series of analogues of 1 were synthesized with a single carbon (pentasaccharide) backbone to facilitate structural characterization and interpretation of biological results. In a fashion similar to 1, all compounds were
磷磺
甘露聚糖1(
PI-88)是高度
硫酸化的低聚糖的混合物,目前正在癌症患者中进行临床评估。除了其抗癌特性外,1还显示了许多其他有趣的
生物学活性。用单个碳(五糖)骨架合成了一系列1的类似物,以促进结构表征和
生物学结果的解释。以类似于1的方式,所有化合物都能够抑制乙酰
肝素酶并与促血管生成生长因子FGF-1,FGF-2和V
EGF紧密结合。该化合物还抑制单纯疱疹病毒(HSV-1)的细胞感染和细胞间传播。初步药代动力学数据表明,与1.相比,该化合物表现出不同的药代动力学行为。
