tri-hydroxy substitutions at the 2,4,6-position of aryl ring C) and 5 (bearing di-hydroxy substitutions at the 3,4-position of aryl ring C) emerged as the most potent inhibitors of urease enzyme and displayed many times more potency than a standard thiourea drug. Besides that, analog 22 (which holds di-hydroxy substitutions at the 2,3-position of the aryl ring) and analog 23 (bearing ortho-fluoro substitution)
合成了 24 种基于带有苯并咪唑/苯并恶唑部分的三嗪吲哚类似物 ( 1 – 25 )。利用各种光谱方法,包括1 H-、 13 C-NMR 和 HREI-MS,对新提供的化合物 ( 1 – 25 ) 进行了分析。与标准硫脲药物相比,合成的类似物针对脲酶进行了测试(体外)。所有基于三嗪吲哚的苯并咪唑/苯并恶唑类似物 ( 1 – 25 ) 均表现出中等至优异的抑制特性,在硫脲作为标准药物的阳性对照下进行评估时,IC 50值为 0.20 ± 0.01 至 36.20 ± 0.70 μM。为了更好地理解构效关系,将合成的化合物分为两组:“A”和“B”。在“A”类类似物中,出现了类似物8 (在芳环C的2,4,6位上带有三羟基取代)和5 (在芳环C的3,4位上带有二羟基取代)作为最有效的脲酶抑制剂,其效力比标准硫脲药物高许多倍。除此之外,类似物22 (在芳环的 2,3 位上具有二羟基取代基)和类似物23
