本发明属于新药设计与合成领域,具体涉及一类新型不饱和去甲斑蝥素甲酯钡盐及其抗肿瘤应用。
背景技术
斑蝥,也写作斑蟊,俗称班苗、西班牙苍蝇等,在我国现存最早的中药学专著《本草纲目》、《神农本草经》等中都曾有记载。斑蝥是芫菁科昆虫南方大斑蟊或黄黑小斑蟊的干燥体,属鞘翅目芫菁科昆虫,是我国最早发现的具有抗癌作用的药材之一。斑蝥性辛,热,具有很强的肾毒性,同时具有破血逐瘀、去除淤积,消肿以及攻毒蚀疮的功效,临床常用于恶疮,顽癣,狂犬病及癌症肿痛等的治疗。而后的研究表明,斑蝥的体内含有一种倍半萜类衍生物,称之为斑蝥素(cantharidin,C10H12O4),具有较高的抗癌活性,具有非常高的药用价值。斑蝥素为无色结晶,不溶于冷水,微溶于热水,溶于丙酮和氯仿。斑蝥素主要存在于多种昆虫中,能使人体皮肤起疱,斑蝥素及其衍生物抗肿瘤的机制主要是抑制蛋白质与酸的合成,增强机体对肿瘤细胞的杀伤力而达到治疗目的。斑蝥素及其类似物对肝癌,卵巢癌,食道癌等有良好的疗效,它是通过改变蛋白质的活性,抗肿瘤侵袭转移,引起细胞周期阻滞,抑制肿瘤生长,从而使得其死亡。其抗肿瘤的机制为通过减少癌细胞对氨基酸的摄取,抑制蛋白质的合成,刺激淋巴细胞、巨噬细胞、多形核细胞产生白细胞介素,从而提高机体免疫力,同时杀伤肿瘤细胞而达到治疗目的,与其他的抗肿瘤药物相比,斑蝥素及其衍生物有许多优点:其在抑制肿瘤的同时,不仅没有免疫抑制的副作用,还能提升机体白细胞等。
但斑蝥素对泌尿系统和肠胃系统有较大的毒副作用,斑蝥素既是抗肿瘤的活性成分,同时也是毒性的主要成分。对其进行恰当的结构修饰,会在保留其抗肿瘤活性的基础上,大大减低对机体的毒副作用,以去甲斑蝥素衍生物的合成为例。去甲斑蝥素不但保留了其较强的抗肿瘤活性和升高白细胞的作用,还消除了其对泌尿系统的副作用,后来,以去甲斑蝥素为先导化合物进行结构改造成为了研究的热点。这种优势在抗肿瘤药物中还是少见的,所以引起了广泛的关注,陆续合成了许多减少其毒副作用但同时又保留其活性的同类药物,开发更新高效低毒的衍生物是一个很好的研究方向。
对斑蝥素进行结构修饰后用于治疗癌症的衍生物近年来陆续的出现,并开始运用于临床治疗。如去甲斑蝥素,它比斑蝥素少了两个甲基,其毒性明显减低,而治疗作用却优于斑蟊素。
目前,斑蝥素和去甲斑蝥素都已经应用在临床中,这两个药物都各具有临床特点,但不足之处是:这两个药物的水溶性都较差,生物利用度不高。从化学结构中看出,斑蝥素和去甲斑蝥素的结构中均包含了分子内酸酐结构。而斑蝥酸即斑蝥素化合物的酸酐水解后得到的二元羧酸化合物;斑蝥酸还未被开发成为药物,仅仅是报道了其结构式。
此外,临床上还研究了斑蝥素钠,去甲斑蝥素钠,甲基斑蝥胺等,这些结构改造均将斑蝥素及去甲斑蝥素的内酸酐环打开,以开环方式存在,从化学结构上看;对应的开环化合物其相应的溶解度较大,其体内生物利用度也高。对斑蝥素的结构进行修饰,寻找高效低毒的斑蝥素抗肿瘤药物,具有重要的工业应用价值和广泛的市场前景。申请号为ZL201410163619.4、ZL201410163711.0、ZL201410163705.5的中国专利公开了制备去甲基斑蝥素酸盐的方法,迄今,尚未有报道设计并合成不饱和去甲斑蝥素甲酯钡盐结构。
