| TITLE： | Synthesis and anti-breast cancer activity of novel cyclic mono-carbonyl curcumin analogues |
| 摘要： | 目的 设计并合成单羰基姜黄素类似物，并考察其抗乳腺癌活性。方法通过羟醛缩合反应获得单羰基姜黄素类似物F1、F2和F3，采用MTT法检测其抗肿瘤（包括人乳腺癌细胞MCF-7和人肺癌细胞A549）活性[以半数抑制浓度（IC50）评估]，并与姜黄素进行比较。根据生物信息学分析方法分别获取F1、F2和F3作用于乳腺癌的第一核心蛋白，并进行分子对接验证。采用细胞实验进一步考察高、中、低浓度（16、8、4μmol/L）的F1、F2和F3对MCF-7细胞中对应第一核心蛋白以及中浓度的F1、F2和F3对细胞中剪切型胱天蛋白酶3（cleaved-caspase-3）表达的影响。结果与姜黄素相比，F1、F2和F3对A549、MCF-7细胞的IC50（F2对A549细胞的IC50除外）均显著降低（P＜0.05或P＜0.01），其中F2对MCF-7细胞的IC50最小，为（9.67±1.27）μmol/L。生物信息学分析结果显示，F1、F2和F3与其对应第一核心蛋白表皮生长因子受体（EGFR）、蛋白激酶B（AKT）、AKT的亲和力指数分别为5.9092、8.4025和6.4866。高浓度的F1可显著降低MCF-7细胞中EGFR蛋白磷酸化水平（P＜0.01），低、中、高浓度的F2和高浓度的F3均可显著降低MCF-7细胞中AKT蛋白磷酸化水平（P＜0.05或P＜0.01），中浓度的F1、F2、F3均可显著升高MCF-7细胞中cleaved-caspase-3蛋白表达水平（P＜0.01）。结论设计合成的单羰基姜黄素类似物F1、F2、F3均具有良好的抗乳腺癌活性，其中F2的抗乳腺癌活性更好。 |
| ABSTRACT： | OBJECTIVE To design and synthesize mono-carbonyl curcumin analogues（MCACs） and investigate the activities of them against breast cancer. METHODS The analogues F1， F2， and F3 were obtained by aldol condensation reaction， and their antitumor activities（including the activities of human breast cancer cell MCF-7 and human lung cancer cell A549） were detected by MTT assay [evaluated with half inhibitory concentration（IC50）]. The results of MTT assay were compared with those of curcumin. Bioinformatics methods were used to collect the core targets of analogues F1， F2 and F3 acting on breast cancer， and then molecular docking verification was carried out. The cell experiments were conducted to investigate the effects of high， medium and low concentrations （16， 8， 4 μmol/L） of F1， F2 and F3 on the expression of the first core target protein as well as the effects of medium concentration of F1， F2 and F3 on the expression of cleaved-caspase-3. RESULTS Compared with curcumin， IC50 of analogues F1， F2 and F3 to A549 and MCF-7 cells（except for IC50 of analogue F2 to A549 cells） were decreased significantly（P＜ 0.05 or P＜0.01）； among them， IC50 of analogue F2 to MCF-7 cell was the lowest， being（9.67±1.27） μmol/L. Bioinformatics analysis showed that index of affinity of analogues F1， F2 and F3 with the first core target epidermal growth factor receptor （EGFR）， protein kinase B （AKT） and AKT were 5.909 2， 8.402 5 and 6.486 6， respectively； high concentration of F1 could significantly reduce the phosphorylation level of EGFR protein in MCF-7 cells（P＜0.01）， while low， medium， and high concentrations of F2 and high concentration of F3 could significantly reduce the phosphorylation level of AKT protein in MCF-7 cells（P＜0.05 or P＜0.01）. Medium concentration of F1， F2， and F3 could significantly increase the expression level of cleaved- caspase-3 protein in MCF-7 cells（P＜0.01）. CONCLUSIONS Designed and synthesized MCACs F1， F2 and F3 all have good anti- breast cancer activity， and F2 has better anti-breast cancer activity. |
