development of multi-targeting drugs is currently being explored as an attractive alternative to combination therapy, especially for the treatment of complex diseases such as cancer. Dihydrofolate reductase (DHFR) and thioredoxin reductase (TrxR) are enzymes belonging to two unrelated cellular pathways that are known to contribute towards cancer cell growth and survival. In order to evaluate whether simultaneous
目前正在探索开发多靶点药物,以作为联合疗法的一种有吸引力的替代方法,尤其是用于治疗诸如癌症等复杂疾病。二氢叶酸还原酶(DHFR)和硫氧还蛋白还原酶(TrxR)是属于两个无关的细胞途径的酶,已知这些途径可促进癌细胞的生长和存活。为了评估二氢三嗪(靶向DHFR)和查耳酮(靶向TrxR)同时抑制DHFR和TrxR是否有益,对乳腺癌MCF-7和结直肠HCT116癌细胞进行了选择的二氢三嗪和查耳酮的组合治疗(1) :1 M的比例。两种组合在低至中度浓度下表现出协同作用。基于该结果,设计并合成了四种合并的二氢三嗪-查尔酮化合物。证明了11a [DHFR IC50 = 56.4μM,TrxR IC50(60分钟)= 12.6μM]和11b [DHFR IC50 = 2.4μM,TrxR IC50(60 min)= 10.1μM]这两种化合物在体外对DHFR和TrxR有抑制作用。该化合物对MCF-7和HC
