The synthesis of twenty seven novel pyrazole derivatives bearing aryl substituted groups at positions 1 and 3 of the pyrazole structural motif and various functional groups at position 4 is presented. The critical step for their synthesis is the TCT/DMF promoted cyclization of the corresponding hydrazine precursors, which provided the desired pyrazole skeleton. The anticancer properties of the novel
介绍了二十七个新颖的吡唑衍生物的合成,这些衍生物在吡唑结构基序的1和3位带有芳基取代基,在4位带有各种官能团。它们合成的关键步骤是TCT / DMF促进了相应肼前体的环化,从而提供了所需的吡唑骨架。在体外评估了新型吡唑衍生物对人前列腺(DU145),黑素瘤(A2058)和乳腺癌(MCF-7)细胞系的抗癌性能。在测试的化合物中,吡唑5a及其甲氧基衍生物3d,e被确定为最有效的化合物,对MCF-7细胞系表现出选择性活性,其IC(50)值为14、10和12 µM。
