Abstract

本发明属药物制备领域,涉及淫羊藿素在制备维罗非尼增敏剂中的应用。本发明进行了增加维罗非尼抗黑色素瘤的活性试验以及有关抑制IGF1-R通路的活化试验,结果显示,所述的淫羊藿素可增加维罗非尼抗黑色素瘤A375的活性,该作用不依赖于淫羊藿素本身是否有抗黑色素瘤作用;淫羊藿素可抑制维罗非尼诱导的IGF-1R及其下游的STAT3的活化;采用IGF-1激活IGF-1R后,淫羊藿素对维罗非尼增敏作用被逆转。所述的淫羊藿素可制备维罗非尼增敏剂,以及制备IGF-1R通路抑制剂;进一步,可以作为药物有效成分,加以药物学上可接受的载体,制备对维罗非尼增敏的药物组合物,以及制备IGF-1R通路抑制剂的药物组合物。

Description

淫羊藿素在制备维罗非尼增敏剂中的用途
技术领域
本发明属药物制备领域。涉及淫羊藿素的医药新用途,具体地涉及淫羊藿素在制备维罗非尼增敏剂中的用途。
背景技术
现有技术公开了黑色素瘤是一种皮肤恶性肿瘤,具有高侵袭、高转移特性,预后差、死亡率高。据流行病学资料显示,恶性黑色素瘤是目前所有恶性肿瘤中发病率增长最快的肿瘤,年增长率约3-5%。虽然黑色素瘤在我国发病率较低,但近年来呈成倍增长势,每年新发病例约2万例。近年来黑色素瘤的治疗有了长足的进步,但其疗效仍不能令人满意。新近的研究发现,约50-70%左右的黑色素瘤存在BRAFv600E突变。维罗非尼(Vemurafenib)是美国FDA2011年批准的一种BRAF抑制剂,主要用于治疗晚期黑色素瘤,临床研究显示,维罗非尼的耐药性比较突出,在应用于患者最初的几个月内显现病情得到缓解,然而大多数情况下,黑色素瘤在随后的数月内出现复发。因此,寻找维罗非尼增敏剂渐显得十分必要,业内研究人员对维罗非尼疗效增敏进行了关注,有研究发现苯乙双胍对维罗非尼有增敏作用,将其作为维罗非尼增敏剂;有研究从天然药物中寻找维罗非尼增敏剂等。
已知淫羊藿素属黄酮醇类化合物,其少量存在于淫羊藿药材中,其化学结构式如下:
目前有关淫羊藿素的药理活性研究报道公开了淫羊藿素具有抗炎症、抗抑郁和抗骨质疏松等药理作用,关于淫羊藿素在制备维罗非尼增敏剂中的用途尚未见报道。
发明内容
本发明的目的在于提供淫羊藿素的新的药用用途,具体涉及淫羊藿素在制备维罗非尼增敏剂中的用途。
本发明所述的淫羊藿素(可市购)属黄酮醇类化合物,少量存在于淫羊藿药材中,其化学结构式如下:
本发明进行了增加维罗非尼(PLX)抗黑色素瘤的活性试验以及有关抑制IGF1-R通路的活化试验,结果显示,所述的淫羊藿素可增加维罗非尼抗黑色素瘤A375的活性,该作用不依赖于淫羊藿素本身是否有抗黑色素瘤作用;淫羊藿素可抑制维罗非尼诱导的IGF-1R及其下游的STAT3的活化;采用IGF-1激活IGF-1R后,淫羊藿素对维罗非尼增敏作用被逆转。
所述的淫羊藿素可制备维罗非尼增敏剂,以及制备IGF-1R通路抑制剂;进一步,可以作为药物有效成分,加以药物学上可接受的载体,制备对维罗非尼增敏的药物组合物,以及制备IGF-1R通路抑制剂的药物组合物。
附图说明
图1显示了淫羊藿素增加维罗非尼的抗黑色素瘤活性(WST-8法),其中,**与单纯PLX组相比,p<0.01,#与单纯淫羊藿素1或10μM相比,p<0.01。
图2显示了维罗非尼可抑制黑色素瘤ERK的活化,对IGF-1R和STAT3则显示了激活作用(western blot法)。
图3显示了淫羊藿素可抑制维罗非尼诱导的黑色素瘤IGF-1R和STAT3活化(western blot法)。
图4显示了淫羊藿素与维罗非尼的协同抗黑色素瘤作用被IGF-1部分逆转(MTT法),
其中,**与Medium组相比,p<0.01,#与淫羊藿素10μM+PLX0.5μM相比,p<0.01。
具体实施方式
实施例1
淫羊藿素对维罗非尼(PLX)抗黑色素瘤的活性影响实验
采用MTT方法观察到,PLX0.5μM作用于A375细胞24h,其细胞活性为70%左右,淫羊藿素1μM作用24h,无抗黑色素瘤活性(细胞活性几乎为100%),而二者联用细胞活性降为60%;淫羊藿素10μM作用24h,细胞活性为63%,淫羊藿素10μM和PLX0.5μM联用细胞活性降为52%;同样,48h的细胞活性结果也显示了同样的趋势,结果表明,淫羊藿素能增加维罗非尼抗黑色素瘤A375的活性(如图1所示)。
实施例2.
淫羊藿素对维罗非尼诱导的IGF-1R及其下游的STAT3的活化影响试验
基于现有技术的BRAF可激活RAS-MEK-ERK通路;维罗非尼作为BRAF抑制剂,可抑制ERK的活化;本实施例中采用western blot的方法证实了上述观点,PLX0.5μM作用2h可显著抑制ERK的活化,然而本实施例中同时观察到,PLX0.5μM对IGF-1R和STAT3显示了激活作用,且呈时间依赖性,以24h最为明显(如图2所示);本实施例中采用不同浓度的淫羊藿素(0,1,10μM)预培养2h,其后以PLX0.5μM干预24h,westernblot结果发现,淫羊藿素(1,10μM)可明显抑制PLX0.5μM诱导的P-IGF-1R和P-STAT3蛋白表达的增加,且显示了较好的量效关系(如图3所示),结果表明,淫羊藿素可抑制维罗非尼诱导的IGF-1R及其下游的STAT3的活化。
实施例3
采用IGF-1激活IGF-1R后,淫羊藿素对维罗非尼增敏作用被逆转,
本实施例采用IGF-1100ng/ml刺激黑色素瘤A375细胞,48h后采用MTT法观察到淫羊藿素10μM与PLX0.5μM抗黑色素瘤的协同效应被部分逆转(如图4所示)。
本发明的实验证实所述的淫羊藿素可制备维罗非尼增敏剂,以及制备IGF-1R通路抑制剂;进一步,可以作为药物有效成分,加以药物学上可接受的载体,制备对维罗非尼增敏的药物组合物,以及制备IGF-1R通路抑制剂的药物组合物。
