Rifabutin (ansamycin; LM427), a semisynthetic rifamycin derivative, inhibits the replication of human immunodeficiency virus type 1, the virus etiologically linked to acquired immunodeficiency syndrome. The inhibition of virus production was observed in human immunodeficiency virus type 1-infected peripheral blood mononuclear cells both by reverse transcriptase assay and virus-antigen assay. In addition, rifabutin effectively reduced human immunodeficiency virus type 1-associated cytopathic effect to OKT4-positive cells. Virion-associated reverse transcriptase was also markedly inhibited by rifabutin. The inhibitory dose of rifabutin was nontoxic to lymphoid cells, which further suggests that it might serve as a useful agent in the therapeutic modalities of acquired immunodeficiency syndrome.
利福布汀(安莎霉素;LM427),一种半合成利福霉素衍生物,可抑制1型人类免疫缺陷病毒的复制,该病毒在病因上与获得性免疫缺陷综合征相关。通过逆转录酶测定和病毒抗原测定,在1型人类免疫缺陷病毒感染的外周血单核细胞中观察到病毒产生受到抑制。此外,利福布汀有效地降低了1型人类免疫缺陷病毒对OKT4阳性细胞的细胞病变效应。利福布汀对病毒体相关的逆转录酶也有明显抑制作用。利福布汀的抑制剂量对淋巴细胞无毒,这进一步表明它可能是获得性免疫缺陷综合征治疗模式中的一种有用药物。
