Description
技术领域
本发明涉及化学和医药领域,特别是一种靶向P53突变体的甾体类化合物及其制备方法、及在治疗肿瘤中的应用。
背景技术
肿瘤严重危害人类健康,是人类发病率和死亡率最高的疾病之一。对肿瘤的预防和治疗已成为研究的重点。尽管肿瘤的治疗有了一定的进展,但是抗肿瘤药物的研发还是任重而道远。Tp53作为抑癌基因,其编码的p53蛋白能够促进DNA损伤修复、细胞周期阻滞和细胞凋亡。然而在超过50%肿瘤细胞中都存在p53基因突变。P53蛋白全长由393个氨基酸组成,包括反式激活结构域(TAD)、DNA结合结构域(DBD)、四聚化结构域(DB)三大功能结构域,其突变主要是发生在DBD区的单点错义突变,导致p53失去原有的肿瘤抑制功能,同时通过功能性获得效应(GOF)进一步促进肿瘤的发生和发展。有报道显示突变p53在肿瘤细胞中通常表达较高,因而其可以成为区别于正常细胞的一个特异性抗肿瘤靶点。
甾体类化合物又称为类固醇类化合物,是由甲戊二羟酸生源合成途径转化而来,且广泛存在于动植物和微生物体内的一类天然化合物。其基本结构由环戊烷并氢化菲、两个角甲基、及C-17位不同侧链构成。同时甾体类化合物还具有高度的亲脂性、良好的生物膜穿透能力等优点,已经成为药物研发的热点,可将其用于肿瘤治疗中。

2.实验结果
以p53为靶点的甾体类化合物中,以化合物13为例,如图3所示,13降低了突变p53的表达,同时增加了野生型p53的表达。
五、蛋白质印迹法
1.实验方法
蛋白质印迹法(免疫印迹试验)即Western Blot。它是分子生物学、生物化学和免疫遗传学中常用的一种实验方法。其基本原理是通过PAGE(聚丙烯酰胺凝胶电泳)分离的蛋白质样品,转移到固相载体(例如PVDF膜)上,固相载体以非共价键形式吸附蛋白质,且能保持电泳分离的多肽类型及其生物学活性不变。以固相载体上的蛋白质或多肽作为抗原,与对应的抗体起免疫反应,再与酶或同位素标记的第二抗体起反应,经过底物显色或放射自显影以检测电泳分离的特异性目的基因表达的蛋白成分。
具体步骤如下:
(1)取对数生长期的HT29、SK-BR-3细胞,采用化合物(5/10μM)处理6h、12h、24h,用细胞刮将细胞刮下,4℃离心,用1×PBS清洗一遍,移至1.5mL离心管中得到细胞沉淀。
(2)加入适宜的细胞裂解液,对细胞沉淀进行超声处理,条件25-30Hz,超10s停5s,共10次,如果沉淀未被完全超声彻底可以适当增加超声次数。提取出的蛋白利用烤蓝或BCA方法进行定量。
(3)配置蛋白上样体系:15μL、20μg,蛋白上样体系中加溴酚蓝(已加β-巯基乙醇)终浓度为1×上样体系;体系配好后,沸水煮10min左右,冷却离心。
(4)电泳:配置12%的分离胶和5%的浓缩胶,配置1×的Running Buffer(含1%的SDS),准备上样。跑胶条件:恒压80V跑30min后切换恒压120V跑1小时30min。
(5)转膜:配置转膜液,200mL甲醇+100mL的10×Running Buffer纯水定容到1L,PVDF膜用之前要用甲醇活化;按照板子黑面-海绵-三层滤纸-胶-PVDF膜-三层滤纸-海绵-板子白面顺序制备转膜装置。转膜条件:恒流200mA、2h。
(6)5%牛奶封闭,先用1×PBST清洗PVDF膜上的转膜液,然后用5%的牛奶常温封闭2h或是37℃封闭1h或是4℃摇床封闭过夜。
(7)标一抗:用1×PBST清洗封闭牛奶,然后用配好的p53(Do-1)(1:500)(SC-126,Santa)、PUMA(1:100)(12450S,CST)、p21(1:1000)(2947S,CST)、Bax(1:500)(5023,CST)抗体4℃摇床过夜。
(8)标二抗:用1×PBST清洗标过一抗的PVDF膜,按照1:10000比例稀释相应种属的HRP标记二抗,室温2h。
(9)显影:用1×PBST清洗标过二抗的PVDF膜,按照1:1比例配置显影液,进行显影。
2.实验结果
靶向突变p53的甾体类化合物中,以化合物13为例,化合物13上调了p53下游蛋白的表达水平,如图4所示。
