Abstract A series of thiazole containing coumarin derivatives ( 2a-o ) were efficiently synthesized as pharmacophore hybrids through Hantzsch cyclisation of 3-(2-bromoacetyl)-2 H -chrome-2-ones with different N -substituted thiourea/ N,N -di-substituted thiourea. All the synthesized compounds were evaluated for their potential as antibacterial, anti-tubercular and antiviral agents and some of the compounds
摘要 通过3-(2-溴乙酰基)-2 H-chrome-2-ones与不同N-取代硫脲/N,N-的Hantzsch环化反应,高效合成了一系列含有噻唑的香豆素衍生物(2a-o)作为药效团杂化物。双取代硫脲。评估了所有合成的化合物作为抗菌剂、抗结核剂和抗病毒剂的潜力,其中一些化合物对这些菌株显示出相当大的效力。噻唑部分的 2-溴苯氨基 (2h) 和 3,4-二氯苯氨基 (2g) 基团的存在分别导致最高的抗菌 (MIC 73 μM) 和抗结核 (MIC 60 μM) 活性。抗病毒筛选显示甲氨基衍生物 (2a) 强烈抑制 H1N1 甲型流感病毒的复制(IC 50 值 4.84)。
