and seven analogues. Four natural lignans were prepared by this method, and five lignans were synthesised for the first time. The synthesised compounds were evaluated for anti-HIV, anti-HSV, and anti-tumour activities. Results showed that the dibenzylbutyrolactone lignans and their analogues were inactive against HIV Tat transactivation and HSV-1 in vitro, but some compounds displayed significant activity
已开发出二苄基丁内酯木脂素及其类似物的有效合成。基于胡椒醛或藜芦醛与琥珀酸二乙酯的 Stobbe 缩合,以及与 3,4-亚甲基二氧苄基溴的烷基化反应,得到木脂素的骨架。(±)-二酸用奎宁分解并转化官能团以获得三种苄基丁内酯木脂素和七种类似物。采用该方法制备了4种天然木脂素,首次合成了5种木脂素。对合成的化合物进行了抗 HIV、抗 HSV 和抗肿瘤活性的评估。结果表明,二苄基丁内酯木脂素及其类似物在体外对 HIV Tat 反式激活和 HSV-1 无活性,但一些化合物对 MDA-MB-435 人乳腺癌细胞显示出显着的活性。
