Eighteen new 4-[2-amino-3-cyano-5-oxo-4-substitutedaryl-4H-indeno[1,2-b]pyridin-1-(5H)-yl]benzenesulfonamide derivatives 6a–q were synthesized via a reaction of aromatic aldehydes, enaminone 3 and malononitrile in one-pot reaction. Also, compounds 6a–q were obtained, via another route by reaction of enaminone 3 with arylidenemalononitriles 4a–q. The structure of the synthesized compounds was characterized by microanalysis, IR, 1H-NMR, 13C-NMR and mass spectral data. All the target compounds were subjected to in vitro anticancer activity against breast cancer cell line (MCF7). Compound 6d showed a higher potency with IC50 value (4.34 μM) than that of the Doxorubicin (5.40 μM), as the reference drug, while compound 6n with IC50 value (6.84 μM) is nearly as active as Doxorubicin. Also, compounds 6a–c, 6e, 6f, 6h and 6p exhibited a moderate activity, while compounds 3, 6g, 6i–m, 6o and 6q showed weak activity.
通过芳香醛、烯胺酮 3 和丙二腈的一锅反应,合成了 18 种新的 4-[2-氨基-3-氰基-5-氧代-4-取代芳基-4H-茚并[1,2-b]吡啶-1-(5H)-基]苯磺酰胺衍生物 6a-q。此外,还通过另一条途径,即烯胺酮 3 与芳基亚甲基丙二腈 4a-q 反应,得到了化合物 6a-q。通过微量分析、红外光谱、1H-NMR、13C-NMR 和质谱数据对合成化合物的结构进行了表征。所有目标化合物都对乳腺癌细胞株(MCF7)具有体外抗癌活性。化合物 6d 的 IC50 值(4.34 μM)比参考药物多柔比星的 IC50 值(5.40 μM)更高,而化合物 6n 的 IC50 值(6.84 μM)几乎与多柔比星的活性相同。此外,化合物 6a-c、6e、6f、6h 和 6p 表现出中等活性,而化合物 3、6g、6i-m、6o 和 6q 则表现出弱活性。
