Baylis-Hillman-derived 3-(benzylaminomethyl)coumarins have been treated, sequentially, with chloroacetyl chloride and propargylamine to afford alkynylated coumarins as substrates for Click Chemistry reactions with azidothymidine (AZT) in the presence of a Cu(I) catalyst. The dual-action HIV-1 protease (PR) and reverse transcriptase (RT) inhibition potential of the resulting N-benzylated cycloaddition products, and a series of non-benzylated analogues, has been explored using saturation transfer difference (STD) NMR, computer modelling and enzyme inhibition techniques.
Baylis-Hillman 衍生的 3-(苄基氨甲基)香豆素依次用氯乙酰氯和丙炔胺处理,得到炔基化香豆素作为底物,在 Cu(I)催化剂存在下与叠氮胸苷 (AZT) 进行点击化学反应。使用饱和转移差 (STD) NMR、计算机建模和酶抑制技术研究了所得 N-苄基环加成产物和一系列非苄基类似物的双重作用 HIV-1 蛋白酶 (PR) 和逆转录酶 (RT) 抑制潜力。
