anomers were obtained by a multistep synthesis with use of 2-amino- or 2-mercapto-alpha-D-xylofuran[1',2':4,5]-2-oxazoline as starting material. The xylofuranosyl nucleosides were tested for their activity against a variety of RNA and DNA viruses and for inhibition of cell growth and macromolecule synthesis. Three compounds, 9-(beta-D-xylofuranosyl)adenine, 9-(beta-D-xylofuranosyl)guanine, and 1-(
天然存在的核苷的α-和β-D-木呋喃糖基类似物,以及其他D-木呋喃糖基衍生物,已成为其生物学(即抗病毒抗代谢和抑制细胞生长)特性的系统合成和研究对象。通过将嘌呤和嘧啶糖苷配基与过酰化的1-O-乙酰基-α-D-木呋喃糖基糖基化,然后除去保护基团来制备β端基异构体。通过使用2-氨基或2-巯基-α-D-木呋喃[1',2':4,5] -2-恶唑啉为起始原料的多步合成法获得α-端基异构体。测试了木呋喃糖基核苷对多种RNA和DNA病毒的活性以及对细胞生长和大分子合成的抑制作用。9-(β-D-木呋喃糖基)腺嘌呤三种化合物
