Enantiomers of 1′,6′-isoneplanocin, including derivatives of the enantiomers of 1′,6′-isoneplanocin, are disclosed along with novel synthetic methods. In particular, a substituted cyclopentane epoxide is synthesized into the enantiomers of 1′,6′-isoneplanocin. Enantiomers of carbocyclic nucleoside analogs of 3-deazaneplanocin to provide D- and L-like 1′,6′-iso-3-deazaneplanocin are also disclosed. The small molecule chemotherapeutic compounds beneficially provide DNA and RNA antiviral activity, demonstrating activity towards, for example, human cytomegalovirus, measles, Ebola, norovirus, dengue, vaccinia and HBV. Compounds exhibiting reduced S-adenosylhomocysteine hydrolase inhibitory effects are disclosed and provide improved toxicity profiles in comparison to neplanocin. The invention provides improved prophylactic and/or therapeutic antiviral efficacy.
1′,6′-isoneplanocin 的对映体,包括 1′,6′-isoneplanocin 对映体的衍生物,以及新的合成方法被公开。特别是将取代的环戊烷环氧化物合成为 1′,6′-异柚皮素的对映体。此外,还公开了 3-去氮杂环庚素的碳环核苷类似物的对映体,以提供 D 型和 L 型 1′,6′-异-3-去氮杂环庚素。这些小分子化疗化合物具有良好的 DNA 和 RNA 抗病毒活性,对人类巨细胞病毒、麻疹、埃博拉、诺如病毒、登革热、疫苗和 HBV 等具有活性。本发明公开了具有降低 S-腺苷-高半胱氨酸水解酶抑制作用的化合物,与萘普拉霉素相比,其毒性特征得到了改善。本发明提高了预防性和/或治疗性抗病毒疗效。
