Novel triazoloquinoxaline‐pyrazole hybrids have been developed and synthesized. All derivatives' anticancer activity has been evaluated using Sulforhodamine‐B (SRB) assay for cancer cell lines MCF‐7, HepG‐2, and HCT‐116. Compound 12b was 2‐fold more cytotoxic than Doxorubicin, while 12a,c demonstrated comparable cytotoxicity to the reference Doxorubicin. Further investigations on the most active derivatives
已经开发并合成了新型三唑并喹喔啉-吡唑杂化物。所有衍生物的抗癌活性已通过Sulforhodamine-B(SRB)分析评估了癌细胞系MCF-7,HepG-2和HCT-116。化合物12b的细胞毒性比阿霉素高2倍,而12a和c则显示出与参考阿霉素相当的细胞毒性。对最具活性的衍生物12a-c进行了进一步研究,以研究其对MCF-7细胞系中两种EGFR亚型野生EGFR和突变型EGFR(L858R)酪氨酸激酶的抑制活性。与吉非替尼(IC 50)相比,化合物12b对野生EGFR(IC 50:0.98μM)表现出有效的抑制活性:18.07μM)。与拉帕替尼(IC 50:61.06μM)相比,12b还具有对表现出(IC 50:27.45μM)的突变EGFR(L858R-TK)的显着抑制作用。化合物12b改善了Caspase-3的活性值和BAX / Bcl-2参照值。此外,12b显示G2 / M细胞周期停滞
