A new series of sulfonamide derivatives of pyrazolo[4,3-e][1,2,4]triazine with chiral amino group has been synthesized and characterized. The compounds were tested for their tyrosinase and urease inhibitory activity. Evaluation of prepared derivatives demonstrated that compounds (8b) and (8j) are most potent mushroom tyrosinase inhibitors whereas all of the obtained compounds showed higher urease inhibitory activity than the standard thiourea. The compounds (8a), (8f) and (8i) exhibited excellent enzyme inhibitory activity with IC 0.037, 0.044 and 0.042 μM, respectively, while IC of thiourea is 20.9 μM.
合成并表征了一系列新型含手性氨基的吡唑并[4,3-e][1,2,4]三嗪磺酰胺衍生物。测试了这些化合物的酪氨酸酶和脲酶抑制活性。对所制备衍生物的评估表明,化合物(8b)和(8j)是最有效的蘑菇酪氨酸酶抑制剂,而所有获得的化合物均显示出比标准硫脲更高的脲酶抑制活性。化合物(8a)、(8f)和(8i)分别表现出优异的酶抑制活性,其IC50分别为0.037、0.044和0.042 μM,而硫脲的IC50为20.9 μM。
