Abstract

Castanospermine and 3'-azido-3'-deoxythymidine (zidovudine) were evaluated in combination against human immunodeficiency virus (HIV) replication in vitro. Castanospermine and 3'-azido-3'-deoxythymidine inhibited HIV type 1 synergistically in acutely infected H9 cells. In addition, they synergistically inhibited both HIV type 1 and HIV type 2 in peripheral blood mononuclear cells. There were no additional toxic effects of these agents in combination. Drug interactions were evaluated by the median-effect principle and the isobologram technique. Combinations of a glycosylation inhibitor, such as castanospermine, with 3'-azido-3'-deoxythymidine deserve consideration for HIV-related chemotherapeutic intervention.

摘要

对栗精胺和3'-叠氮-3'-脱氧胸苷(齐多夫定)联合抗人免疫缺陷病毒(HIV)体外复制的效果进行了评估。栗精胺和3'-叠氮-3'-脱氧胸苷在急性感染的H9细胞中对1型HIV具有协同抑制作用。此外,它们在外周血单核细胞中对1型HIV和2型HIV均有协同抑制作用。这些药物联合使用没有额外的毒性作用。通过中位效应原理和等效线图技术评估药物相互作用。糖基化抑制剂如栗精胺与3'-叠氮-3'-脱氧胸苷的联合用药值得考虑用于HIV相关的化疗干预。
