摘要

我们早些时候曾报道过，抗病毒药物奥司他韦（Osm，Tamiflu®）可抑制滋养体附着在肠上皮细胞上并在培养过程中产生囊肿。Osm 还能分解脂质筏（LRs）和贾第鞭毛虫胞外囊泡（EVs）的生物生成。在目前的研究中，我们利用磷酸奥司他韦衍生合成了 41 种 Osm 类似物。这些化合物对贾第鞭毛虫的生长和包囊的产生进行了测试。结果发现，与母体奥司他韦相比，其中四种类似物，即化合物 3b、2c、11i 和 11d 对滋养体和包囊具有更强的活性。对这些制剂作用机制的研究正在进行中，将在适当的时候报告。

Synthesis and evaluation of anti-Giardia activity of oseltamivir analogs

We reported earlier that oseltamivir (Osm, Tamiflu®), an anti-viral agent, inhibits the attachment of trophozoites to intestinal epithelial cells and cyst production in culture. Osm also disassembles lipid rafts (LRs) and the biogenesis of extracellular vesicles (EVs) by Giardia. In the current study, we synthesized forty-one Osm analogs with the derivatization of oseltamivir phosphate. These compounds were tested on giardial growth, and cyst production. Of these, four analogs, i.e., compounds 3b, 2c, 11i, and 11d, were found to have superior activities against trophozoites and cysts compared to the parent oseltamivir. Investigation of the mechanism(s) of action of these agents are in progress and will be reported in due course.
