didanosine (DDI) and acyclovir, respectively. A quantitative structure–activity relationship (QSAR) study of these compounds as well as previous reported oxadiazolo[3,4-d]pyrimidine nucleoside derivatives indicated that compounds with high activity should have small values of log P(o/w), vsurf_G and a large log S value. These findings and results provide a base for further investigations.
我们合成了一系列的4 H,6 H- [1,2,5]恶二唑[3,4- d ]嘧啶-5,7-二酮1-氧化物核苷及其抗水泡性口炎病毒(VSV)活性。希望细胞也进行了体外研究。发现大多数化合物显示出明显的抗VSV活性,并且具有呋喃核糖苷的化合物9与去羟肌苷(DDI)和无环鸟苷相比分别提高了约10倍和18倍的抗VSV活性。对这些化合物以及先前报道的恶二唑并[3,4- d ]嘧啶核苷衍生物的定量构效关系(QSAR)研究表明,具有高活性的化合物应具有较小的log P(o/ w),vsurf_G和较大的log S值。这些发现和结果为进一步的研究奠定了基础。
