(compounds 5, 6, 13, 16, and 17) displayed promising selectivity against hCOX‐1 in the micromolar range and were shown to have a selectivity index similar or better than the reference drugs (indometacin, diclofenac). The introduction of a phenyl or a 4‐F‐phenyl ring on the C5 associated with a 4‐substituted phenyl or a heteroaryl group on the C3 of (4‐substituted‐thiazol‐2‐yl)pyrazoline derivatives improved
3,5-二(杂)芳基-1-硫代氨基甲酰基-2-反应得到新型1-(4-乙基羧酸酯-噻唑-2-基)-3,5-二(杂)芳基-2-吡唑啉衍生物吡唑啉与α-溴-丙酮酸乙酯。合成的化合物通过光谱数据得到证实,并进行了分析,以评估它们在体外抑制人类环氧合酶 (hCOX) 两种异构体的能力。一些衍生物(化合物 5、6、13、16 和 17)在微摩尔范围内对 hCOX-1 显示出有希望的选择性,并且显示出与参考药物(吲哚美辛、双氯芬酸)相似或更好的选择性指数。在(4-取代-噻唑-2-基)吡唑啉衍生物的 C3 上与 4-取代苯基或杂芳基相连的 C5 上引入苯基或 4-F-苯环提高了对 hCOX-的活性1.
