Abstract

Currently, clinically approved nucleos (t) ide analogs (NAs) are very efficient in reducing the load of hepatitis B virus (HBV) with minimum side effects. Chronic hepatitis B (CHB) is one of the major causes of morbidity and mortality worldwide. However, the long-term administration of antiviral drugs promotes HBV for potential drug resistance. Herein, 2'-fluoro-6'-methylene carbocyclic adenosine (FMCA) and its phosphoramidate (FMCAP) have been discovered, which may be utilized in combination with therapies for curing drug-resistant chronic hepatitis B. In preclinical studies, these carbocyclic NAs demonstrated potential anti-HBV activity against adefovir, as well as lamivudine (LMV / LAM) drug-resistant mutants. In vitro, these peptides have demonstrated significant activity against LMV / ent Preliminary studies of FMCA / FMCAP in chimeric mice and female Non-obese diabetic / severe combined immunodeficiency (NOD / SCID) mouse models having the LMV / ETV triple mutant shown a high rate of reduction of HBV DNA levels compared to ETV. In this review, we have summarized preclinical studies of FMCA and its phosphoramidate prodrug (FMCAP).

抽象

目前,临床批准的核苷(酸)类似物(NAs)在减少乙肝病毒(HBV)负荷方面非常有效,副作用最小。慢性乙型肝炎(CHB)是世界范围内发病率和死亡率的主要原因之一。然而,抗病毒药物的长期使用会促进HBV的潜在耐药性。在此,已经发现了2'-氟-6'-亚甲基碳环腺苷(FMCA)及其氨基磷酸酯(FMCAP),其可与用于治疗耐药性慢性乙型肝炎的疗法组合使用。在临床前研究中,这些碳环NAs显示出对阿德福韦以及拉米夫定(LMV / LAM)耐药突变体的潜在抗HBV活性。在体外,这些肽已经显示出针对LMV / ent的显着活性嵌合小鼠和具有LMV / ETV三重突变体的雌性非肥胖糖尿病/严重联合免疫缺陷(NOD / SCID)小鼠模型中FMCA / FMCAP的初步研究显示出高的比率与ETV相比,HBV DNA水平降低。在这篇综述中,我们总结了FMCA及其氨基磷酸酯前体药物(FMCAP)的临床前研究。

——以后可以像HIV那样,组合用药,提高药效,进一步降低副作用
