nucleoside mimetics containing a 1,2,3-triazole linker. The (1,2,3-triazolyl)isoxazolidine phosphonates obtained herein were evaluated in vitro for activity against a variety of DNA and RNA viruses. None of the compounds were endowed with antiviral activity at subtoxic concentrations. Compounds 15f-j and 16f-j were cytostatic in the higher micromolar range.
反式和顺式-5-乙酰氧基-2-甲基异恶唑烷-3-基-3-膦酸盐在异头碳原子上的 9:1 混合物的叠氮化(TMSN(3)、SnCl(4))导致形成顺-和反-5-叠氮基-2-甲基异恶唑烷-3-基-3-膦酸盐的等摩尔混合物,它们被有效分离。纯反式和顺式-5-叠氮异恶唑烷-3-基-3-膦酸酯与选定的炔烃的 1,3-偶极环加成得到含有 1,2,3-三唑接头的相应核苷模拟物。在体外评估了本文获得的(1,2,3-三唑基)异恶唑烷膦酸盐对多种DNA和RNA病毒的活性。没有一种化合物在亚毒性浓度下具有抗病毒活性。化合物 15f-j 和 16f-j 在较高微摩尔范围内具有细胞抑制作用。
