In general, benzothiazole derivatives have attracted great interest due to thier pharmaceutical and biological importance. New 2-amino-6-arylbenzothiazoles were synthesized in moderate to excellent yields via Suzuki cross coupling reactions using various aryl boronic acids and aryl boronic acid pinacol esters and the antiurease and nitric oxide (NO) scavenging activity of the products were also examined. The most active compound concerning urease enzyme inhibition was 6-phenylbenzo[d]thiazole-2-amine 3e, with an IC50 value of 26.35 µg/mL. Compound 3c, 6-(4-methoxyphenyl) benzo[d]thiazole-2-amine, exhibited the highest nitric oxide percentage scavenging at 100µg/mL.
总的来说,苯并噻唑衍生物因其在医药和生物学方面的重要性而引起了人们的极大兴趣。本研究利用各种芳基硼酸和芳基硼酸频哪醇酯,通过铃木交叉偶联反应合成了新的 2-氨基-6-芳基苯并噻唑,产率从中等到极好,并考察了产品的抗尿素酶和一氧化氮(NO)清除活性。对脲酶酶抑制作用最强的化合物是 6-苯基苯并[d]噻唑-2-胺 3e,其 IC50 值为 26.35 µg/mL。化合物 3c,即 6-(4-甲氧基苯基)苯并[d]噻唑-2-胺,在 100µg/mL 时的一氧化氮清除率最高。
