A series of novel pyrazolo[3,4-b]pyridine derivatives were designed, synthesized, and biologically evaluated for anti-lung cancer activity. Structure–activity relationship and AutoGPA models were constructed based on the in vitro antiproliferative potency of the compounds against a human lung adenocarcinoma cell line (A549). Compound 9d exhibits improved potency for A549 cell growth inhibition (3.06 ± 0
设计、合成了一系列新型吡唑并[3,4- b ]吡啶衍生物,并对其抗肺癌活性进行了生物学评估。基于化合物对人肺腺癌细胞系 (A549) 的体外抗增殖效力构建了构效关系和 AutoGPA 模型。与 A-769662 (45.29 ± 2.14 μM) 相比,化合物9d表现出对 A549 细胞生长抑制的效力提高 (3.06 ± 0.05 μM)。化合物9d在 1 μM 时可提高一磷酸腺苷活化蛋白激酶 (AMPK) 及其底物乙酰辅酶 A 羧化酶的磷酸化水平并降低磷酸化核糖体 S6 激酶 (p-70S6K) 的水平,其活性与 A -769662 在 20 μM。9天诱导 G2/M 细胞周期停滞,当与“化合物 C”(一种有效的 AMPK 抑制剂)共同孵育时得以挽救。总之,化合物9d通过调节A549细胞中的AMPK/70S6K通路诱导细胞周期停滞,显示出潜在的抗肺癌活性,这可能为抗肺癌药物的发现提供新的线索。
