摘要:
背景: 人类巨细胞病毒(HCMV)感染仍然是免疫强化患者的主要问题。目前批准了三种抗病毒剂,即Ganciclovir(GCV),Fosarnet(FOS)和Cidofovir(CDV),用于治疗HCMV感染。它们都靶向病毒DNA聚合酶,并与显着的副作用相关。作用于其他靶标(ART)与当前批准的药物或最终Letermovir或Maribavir(MBV)的新型抗病毒化合物的组合可能导致协同作用。 Here, we evaluated the in vitro activity of a series of two-drug combinations against a wild-type recombinant HCMV strain by the Gaussia luciferase (GLuc) reporter assay.
METHODS: The in vitro activity of each drug was first tested individually against HCMV by using the GLuc记者测定法。 The activity of two-drug combinations consisting of ART and currently approved drugs, as well as letermovir or MBV, was then analysed by the Chou-Talalay method.
RESULTS: The concentrations of GCV, FOS, CDV and ART that reduced the GLuc activity by 50% (ECvalues) were 3.92±1.64 µm,62.45±8.39 µm,0.68±0.19 µm和3.86±1.25 µm,而MBV和Letermovir的分别为64±22 nm和2.50±0.83 Nm。 ART与GCV,CDV或MBV的结合与协同作用有关,而ART与FOS或Letermovir Res的组合Ultedin中度协同作用。正如预期的那样,MBV与GCV的组合具有拮抗作用。
结论:
