CuSO4/hydrazine hydrate was used as a catalyst system for copper(I)-catalyzed alkyne-azide cycloaddition (CuAAC) of AZT and 5′-azido adenosine with terminal alkynes to give 30 novel 1,2,3-triazole derivatives. Screening for their anticancer, anti-inflammatory, angiotensin-converting enzyme 2 (ACE2), and 3C-like protease (3CLpro) inhibitory activities showed that several triazoles of AZT containing murayafoline A and indirubin-3′-oxime inhibited the growth of HepG2 and LU-1 with the IC50 values ranging from 11.01 to 19.87 μg/mL. Besides that, some triazole derivatives of adenosine exhibited anti-inflammatory activity against RAW264.7 cells with the IC50 values within an interval of 12.00–59.48.00 μg/mL. Especially, two triazoles of adenosine with indirubin-3′-oxime at O- and N1 positions expressed the ACE2 and 3CLpro inhibitory activities in which the triazole of adenosine with indirubin-3′-oxime at N1 inhibited both ACE2 and 3CLpro inhibitory activities with IC50 values of 135.62 and 142.95 μg/mL, respectively.
以 CuSO4/hydrazine hydrate 为催化剂体系,铜(I)催化了 AZT 和 5′-叠氮腺苷与末端炔烃的炔烃-叠氮环加成反应(CuAAC),得到了 30 种新型 1,2,3- 三唑衍生物。对这些衍生物的抗癌、抗炎、血管紧张素转换酶 2(ACE2)和 3C 样蛋白酶(3CLpro)抑制活性的筛选表明,含有 murayafoline A 和 indirubin-3′-oxime 的 AZT 的几种三唑类衍生物可抑制 HepG2 和 LU-1 的生长,其 IC50 值在 11.01 到 19.87 μg/mL 之间。此外,腺苷的一些三唑衍生物对 RAW264.7 细胞具有抗炎活性,IC50 值在 12.00-59.48.00 μg/mL 之间。特别是腺苷的两个三唑类衍生物,在 O 位和 N1 位上含有靛红-3′-肟,具有抑制 ACE2 和 3CLpro 的活性,其中在 N1 位上含有靛红-3′-肟的腺苷三唑类衍生物同时具有抑制 ACE2 和 3CLpro 的活性,IC50 值分别为 135.62 和 142.95 μg/mL。
