OBJECTIVE To design and synthesize trifluoromethoxy chalcone derivatives based on the natural licorice chalcone parent as the lead compound backbone, and to study their anti-cervical cancer activity in vitro. METHODS New trifluoromethoxy chalcone derivatives were synthesized by Claisen-Schmidt aldol condensation. The structures were confirmed by 1H-NMR, 13C-NMR and HR-ESI-MS. The cytotoxic activity of the target compounds on cervical cancer cell lines HeLa, SiHa, C-33A and normal cervical epithelial immortalized H8 cells were determined by MTT assay, and the structure activity relationship (SAR) was analyzed and the candidate compounds were selected. The effects of candidate compound 3o on invasion, migration, apoptosis and cell cycle of HeLa cells were determined by Transwell and flow cytometry. The candidate compound 3o was docked to the MDM2 and protein target by molecular docking method, and the binding ability and binding characteristics of the compound to the target protein molecules were determined. The regulatory effects of the candidate compounds on MDM2 and p53 proteins were assessed using Western Blot analysis. RESULTS Twenty new trifluoromethoxy chalcones were synthesized. Candidate compound 3o showed the strongest inhibitory activity against cervical cancer cells (IC50=4.60±0.40 μmol·L-1), which was significantly better than that of positive drug cisplatin (IC50=17.16±0.93 μmol·L-1). The candidate compound 3o could effectively inhibit the invasion and migration of HeLa cells, induce apoptosis and arrest the cell cycle at G0/G1 phase. Candidate compound 3o binds to key amino acids in p53 binding pocket of MDM2 protein (binding energy -37.62 kcal·mol-1). The compounds significantly downregulated MDM2 protein expression while upregulating p53 protein levels. CONCLUSION The research results provide experimental evidence for screening new chalcone derivatives as targeted, effective, and low-toxicity anti-tumor candidates against cervical cancer.

目的 以天然甘草查尔酮母核为先导化合物骨架,设计、合成三氟甲氧基查尔酮类衍生物,并对其进行体外抗宫癌活性研究。方法 通过Claisen-Schmidt羟醛缩合反应,合成全新三氟甲氧基查尔酮类衍生物,结构经1H-NMR、13C-NMR及HR-ESI-MS进行确证。四唑盐(MTT)法测定目标化合物对HeLa、SiHa、C-33A三种宫颈癌细胞及正常宫颈上皮永生化H8细胞的毒性,并做构效关系分析,选定候选化合物。Transwell法和流式细胞仪技术测定候选化合物3o对HeLa细胞的侵袭迁移,促凋亡及对细胞周期的影响;分子对接法将候选化合物与鼠双微粒2(MDM2)蛋白靶点进行分子对接,测定化合物3o与靶蛋白分子的结合能力及结合特点;Western blot法测定候选化合物3o对MDM2和p53蛋白的调控作用。结果 - 合成20个全新三氟甲氧基查尔酮类目标化合物,候选化合物3o对宫颈癌细胞的毒性最强(IC50=4.60±0.40 μmol·L-1),明显优于阳性药顺铂(IC50=17.16±0.93 μmol·L-1);候选化合物3o可有效抑制HeLa细胞的侵袭迁移,对HeLa细胞有显著的促凋亡作用并让细胞周期停留在G0/G1期;候选化合物3o与MDM2蛋白p53结合口袋的关键氨基酸有效结合(结合能-37.62 kcal·mol-1);候选化合物3o对MDM2蛋白有明显下调作用,对p53蛋白有明显上调作用。结论 本研究结果为筛选有效低毒的新型靶向查尔酮类抗肿瘤候选药物提供一定实验基础。

OBJECTIVE To design and synthesize trifluoromethoxy chalcone derivatives based on the natural licorice chalcone parent as the lead compound backbone, and to study their anti-cervical cancer activity in vitro. METHODS New trifluoromethoxy chalcone derivatives were synthesized by Claisen-Schmidt aldol condensation. The structures were confirmed by 1H-NMR, 13C-NMR and HR-ESI-MS. The cytotoxic activity of the target compounds on cervical cancer cell lines HeLa, SiHa, C-33A and normal cervical epithelial immortalized H8 cells were determined by MTT assay, and the structure activity relationship (SAR) was analyzed and the candidate compounds were selected. The effects of candidate compound 3o on invasion, migration, apoptosis and cell cycle of HeLa cells were determined by Transwell and flow cytometry. The candidate compound 3o was docked to the MDM2 and protein target by molecular docking method, and the binding ability and binding characteristics of the compound to the target protein molecules were determined. The regulatory effects of the candidate compounds on MDM2 and p53 proteins were assessed using Western Blot analysis. RESULTS Twenty new trifluoromethoxy chalcones were synthesized. Candidate compound 3o showed the strongest inhibitory activity against cervical cancer cells (IC50=4.60±0.40 μmol·L-1), which was significantly better than that of positive drug cisplatin (IC50=17.16±0.93 μmol·L-1). The candidate compound 3o could effectively inhibit the invasion and migration of HeLa cells, induce apoptosis and arrest the cell cycle at G0/G1 phase. Candidate compound 3o binds to key amino acids in p53 binding pocket of MDM2 protein (binding energy -37.62 kcal·mol-1). The compounds significantly downregulated MDM2 protein expression while upregulating p53 protein levels. CONCLUSION The research results provide experimental evidence for screening new chalcone derivatives as targeted, effective, and low-toxicity anti-tumor candidates against cervical cancer.

宫颈癌是妇科肿瘤,其发病率和死亡率均较高[1]。目前化疗仍然是治疗宫颈癌的一个重要手段。然而化疗药物的毒性及癌症的复发和耐药问题仍为临床上的疑难问题[2]。开发新型抗肿瘤药物及新的抗肿瘤靶点具有重要的意义。
p53是肿瘤抑制因子,参与调节细胞周期和细胞凋亡,当细胞发生突变或损伤时,p53蛋白迅速大量聚集,清除突变细胞,保护机体,是肿瘤出现及生长的主要调控蛋白之一[3-5]。鼠双微粒体2(murine double minute 2, MDM2)蛋白是p53基因的负调控因子,MDM2通过不断地泛素化p53蛋白使其形成MDM2-p53复合物,从而使p53失去促凋亡活性,形成相互影响的自动调节反馈回路[6-9]。若能阻断MDM2-p53蛋白之间的相互作用,下调MDM2基因的表达,减少复合物形成,则可以使p53从MDM2上游离出来,恢复和激活p53的抑癌功能,这是通过促进癌细胞凋亡来增强抗癌作用的一种重要途径[10-12]
天然植物中的查尔酮(chalcone,图1)化学名为1,3-二苯基-2-丙烯-1-酮,是一类抗瘤谱较广的天然活性物质,因分子具有较大的可塑性,能与不同靶点结合[13-14]。研究显示,某些查尔酮类化合物能与MDM2结合,竞争性抑制MDM2与p53的结合,从而激活p53的抑癌功能[15-17]。然而植物中的查尔酮含量极低,富集制备成本高,活性较弱,限制了其研究和开发应用。有学者通过Claisen-Schmidt羟醛缩合反应合成了查尔酮类衍生物[18],并在骨架结构中引入不同官能团,不仅能降低制备成本,还能提高其抗肿瘤活性。
本课题组在前期研究中,对查尔酮骨架通过氯代、甲氧基化、α-甲基化及引入杂环等途径得到抗宫颈癌活性较高的抗肿瘤化合物[19-21]。查尔酮结构上引入含有N、O、F等元素的官能团可提高其与靶点形成氢键的能力,增强抗癌活性潜力[22-23]
本研究在前期结构修饰经验基础上,以MDM2-p53靶点作为靶标蛋白,通过分子对接技术设计并用Claisen-Schmidt反应合成了20个全新三氟甲氧基查尔酮类化合物;以三种宫颈癌细胞做体外药理实验模型,筛选出对宫颈癌具有显著细胞毒性、促进凋亡、抑制肿瘤迁移侵袭特点的候选药物,并用H8正常细胞模型初步评估细胞毒性;对候选化合物与MDM2进行分子对接,测定与靶蛋白的结合能力及结合特点,通过Western blot法测定了对MDM2和p53调控作用,进一步验证候选化合物可通过结合MDM2,抑制MDM2-p53复合物形成发挥抗癌作用。

以HeLa, SiHa, C-33A 三种宫颈癌细胞和正常宫颈H8细胞作受试细胞,对20个化合物的抗宫颈癌活性进行初步筛选,顺铂作阳性对照,结果见表1。实验结果表明,与阳性药相比,目标化合物3o对HeLa细胞的毒性最强,(IC50=4.60±0.40 μmol·L-1),对正常细胞毒性低。
通过查尔酮衍生物抑制宫颈癌细胞增殖作用的初步分析中发现,查尔酮骨架中A、B环上取代基的位置和数量特征对化合物的生物活性影响较大。本研究合成的化合物均为A环上有甲氧基、B环有三氟甲氧基的衍生物,氧基的位置和数量对HeLa细胞增殖的抑制活性有明显差别。
活性比较中发现,随着环上甲氧基的数量增多,活性有增强的趋势,即:三甲氧基>二甲氧基>单甲氧基。B环不同部位取代的三氟甲氧基与活性的关系中发现,对宫颈癌细胞增殖的抑制活性从强到弱依次为2'-OCF3>3'-OCF3>4'-OCF3。如候选化合物3o的活性最强, 其IC50=(4.60±0.40) μmol·L-1
细胞迁移侵袭是肿瘤细胞基础功能之一,也是癌症发生和转移的原因之一。细胞迁移侵袭实验是评估肿瘤细胞在正常组织中转移的能力的常用方法。本实验通过Transwell法观察候选化合物3o对HeLa细胞的迁移和侵袭能力的影响(图3~4),结果表明,候选化合物3o随着浓度提高对HeLa细胞迁移和侵袭抑制作用显著增加,有统计学意义(P<0.001),说明化合物3o可以通过抑制细胞迁移和侵袭来抑制肿瘤发生和转移。
采用AnnexinnV-FITC/PI双染法结合流式细胞仪检测候选化合物3o对HeLa细胞凋亡的影响(图5)。结果显示,用3o干预24 h后,低、中、高浓度凋亡率分别(10.57±0.85)%、(15.57±1.58)%、(32.97±2.48)%,与空白组(5.8±0.95)%相比,随着浓度的增加,促凋亡作用逐渐增强,说明候选化合物3o可以通过促细胞凋亡起抗肿瘤作用。
采用PI单染法结合流式细胞仪测试候选合物3o对HeLa周期的影响(图6)。与空白组相比,随着化合物3o的浓度增加,G0/G1期细胞逐渐增加,G2/M期明显减少并有浓度依赖性(P<0.05);与同浓度阳性药顺铂组相比,化合物3o对HeLa细胞G0/G1期的阻滞作用更明显,说明该化合物能明显影响细胞周期,使大部分细胞阻滞在G0/G1期,从而影响宫颈癌细胞增殖,发挥抗肿瘤作用。
从二维图 (图7)可以看出,化合物3o与MDM2(PDB ID= 5TRF)蛋白可形成2个至关重要的氢键。 通过三维图可发现,候选化合物3o的A环甲氧基部分C4位的氧与受体蛋白亚基D链上第105位的氨基酸残基形成氢键,同时,B环上的三氟甲氧基的氟原子与蛋白A链上第109位的氨基酸残基形成氢键。化合物3o与其他氨基酸残基如ARG-105(A)、LYS-98(B)和ARG-97(B)等形成强烈的疏水性相互作用。化合物3o与MDM2蛋白结合的最低能量为-37.62 kJ·mol-1,比查尔酮(-33.44 kJ·mol-1)和MDM2-p53分子抑制剂Nutlin-3a(-37.20 kJ·mol-1)均相当。以上数据显示,候选化合物能与MDM2蛋白稳定结合,可初步判断该化合物抗宫颈癌作用可能与MDM2结合,阻断MDM2-p53相互作用有关。
通过Western blot实验测定候选化合物3o干预过后的HeLa细胞中的p53和MDM2蛋白的表达(图8),结果显示与对照组相比p53蛋白表达水平明显上调,MDM2蛋白的表达水平明显下调,推测化合物3o能与MDM2蛋白结合,较好地激活p53的表达,抑制MDM2表达。
本研究以甘草查尔酮为先导化合物骨架,基于MDM2-p53结合位点为对接部位,设计并合成了20个全新三氟甲氧基查尔酮类衍生物。通过MTT实验进行活性筛选和初步的构效关系分析,并筛选了活性高而毒性较低的候选化合物3o;进一步实验证明,化合物3o可明显抑制宫颈癌HeLa细胞的迁移和侵袭,促进细胞凋亡,可将细胞增殖阻滞在G0/G1期。分子对接研究结果显示化合物3o能与MDM2蛋白的p53结合位点稳定结合(结合能为-37.62 kJ·mol-1)。以上研究结果提示,化合物3o对宫颈癌细胞增殖具有显著抑制作用,并可促进癌细胞凋亡和抑制迁移和侵袭。结合分子对接结果初步预测,其抗癌作用可能是通过与MDM2结合,抑制MDM2-p53复合物的形成,激活p53蛋白功能来实现。本研究为新型查尔酮类抗癌候选药物筛选而奠定一定的实验基础。
