A variety of diarylpyrazole derivatives III-VI were synthesized and structurally characterized using FTIR, 1H and 13C NMR spectroscopy, and in case of compound VIb by X-ray single crystal analysis. The in vitro biological studies revealed that seven of the diarylpyrazole derivatives IIIa, IIIb, IIId, IIIe, IVa, IVb and IVd are highly potent inhibitors of acetylcholinesterase enzyme with IC50 values
合成了多种二芳基吡唑衍生物III-VI ,并使用 FTIR、 1 H 和13 C NMR 光谱对化合物VIb的情况进行了 X 射线单晶分析并对其进行了结构表征。体外生物学研究表明,七种二芳基吡唑衍生物IIIa 、 IIIb 、 IIId 、 IIIe 、 IVa 、 IVb和IVd是乙酰胆碱酯酶的高效抑制剂,IC 500.48 ± 0.092 µg/mL、0.45 ± 0.093 µg/mL、0.30 ± 0.014 µg/mL、0.59 ± 0.072 µg/mL、0.29 ± 0.084 µg/mL、0.56 ± 0.010 µg/mL 和 0.28 ± 0.096 µg/mL , 分别。所有这七种产品都比标准药物多奈哌齐 (IC 50 = 0.73 ± 0.015 µg/mL) 更有效,而化合物IIIc (0.67 ± 0.099 µg/ml) 和VIa (0.66 ± 0.069
