本发明属于医药技术领域,涉及呋喃并[2,3-e][1]苯并呋喃类化合物及其抗乳腺癌的用途。
背景技术
临床研究表明,乳腺癌是一种恶性肿瘤,大约三分之二的乳腺癌属于雌激素受体阳性乳腺癌,其发生、发展与雌激素和雌激素受体密切相关(Katzenellenbogen BS,FrasorJ.Semin Oncol,2004,31(Suppl 3):28-38.)。典型的雌激素受体包括ERα和ERβ两种亚型,多数乳腺肿瘤表达ERα和ERβ两种受体,ERα和ERβ的比值在良性和恶性乳腺肿瘤中不同,在良性组织中以ERβ表达为主,而在恶性组织中ERα占优势。在乳腺肿瘤发生发展过程中ERα升高而ERβ降低,ERα和ERβ的比值升高(Balf PJ,McCann AH,Welch HM,et al.EuropeanJournal of Surgical Oncology,2004,30(10):1043.)。目前在乳腺癌的临床治疗中,使用选择性雌激素受体调节剂(SERMs)是主要治疗方法之一。SERMs是一种类似于雌激素的非雌激素药物,属于非甾类化合物,只对某一种ER亚型ERα或ERβ有激动作用而对另一亚型无作用或有拮抗作用的药物。其“选择性”是指SERMs在某些组织如骨、肝、心血管系统ERβ集中区中表现为激动剂,而在另外一些组织如乳腺中表现为拮抗剂,在子宫(ERα较显著区)中可以是激动剂,也可以是拮抗剂(Katzenellenbogen B S,Katzenenllenbogen J A.Science,2002,295(5564):2380-2381.Pennisi E.Science,1997,277(5331):1439.)。SERMs是一类结构多样的分子家族,根据其母核结构和非甾体雌激素拮抗剂的化学分类方法,可将SERMs分为三苯乙烯类(triphenylethylenes,TPE),苯并噻吩类(benzotriophenes),苯并吡喃类(benzopyrans),萘类(naphthalenes),吲哚类(indoles)及其他类共6类(Miquel JF,Gilbert J.J S teroid Biochem,1988,31(4B):525-544.)。但临床上常用的SERMs生物利用度低,易产生耐药性,具有毒副作用大等缺点,因此寻找治疗效果更好,生物利用度高,毒副作用小的SERMs是当今研究方向。
苯并噻吩类SERMs的代表药物是雷洛昔芬(raloxifene),是第二代SERMs,通过与ER结合在乳腺组织中表现为拮抗作用,能抑制雌激素诱发的乳腺增生(Liu H,Lee ES,Gajdos C,et al.Journal of the National Cancer Institute,2003,95:1586-1597.),并且在动物体内能抑制肿瘤生长(Clemens JA,Bennett DR,Black LJ,Jones CD.LifeScience,1983,32:2869-2875.,可降低乳腺肿瘤细胞的增殖活性(Lopes-Costa PV,dosSantos AR,dos Santos LG,et a1.Cell Proliferation,2010,43(2):124-129.),并且能降低血脂、预防及治疗骨质疏松,在治疗剂量下不升高子宫内膜癌的发病率(范忠林,李海平,呈祥德.中华现代外科学杂志,2004,1(1):51-54.)。但其临床效果并不是非常显著,有效率仅为33%(Gradishar W,G1usIllan J Y,et a1.Cancer,2000,88(9):2047.),也可导致热潮红和小腿痛性痉挛等不良反应(Davies G C,Huster W J,Lu Y,et al.Obstetrics&Gynecology,1999,93(4):558-565.)。
我们根据电子等排原理对苯并噻吩类化合物进行结构改造,设计并合成了一系列呋喃并[2,3-e][1]苯并呋喃类化合物,以克服现有的SERMs上述缺点。

实验方法:待细胞培养至对数生长期后,贴壁细胞用0.25%的胰酶消化液消化约2min,加入10%胎牛血清DMEM/L-15培养基终止消化,吹打成细胞悬液,移入15ml离心管,1000转,离心5min弃上清,加入10%胎牛血清DMEM培养基,吹打混匀,制备成单细胞悬液,调整细胞悬液浓度为5.0×104个/ml,将上述细胞悬液铺于96孔板中,每孔200ul,每组设3个孔;另留3个孔,各加入10%胎牛血清DMEM/L-15培养基200ul作为空白对照孔。继续培养24h后,吸弃各孔培养基,再加入配置好的不同浓度的含待测药物的培养基180ul,使各组待测药物终浓度分别为0.03、0.1、0.3、1、3、10、30、100uM;对照组加入普通培养基180ul;继续培养48h后取出培养板,每孔加入5mg/ml的MTT 20ul,避光孵育4h,吸弃培养基,每孔加入DMSO150ul,震荡摇匀,在酶标仪上以570nm的波长测定吸光度值。重复3次。计算生长抑制率。细胞生长抑制率=[1-(实验组吸光度平均值﹣空白对照吸光度平均值)/(对照组吸光度平均值﹣空白对照吸光度平均值)]×100%。应用SPSS16.0统计软件,计算IC50值。
