Abstract

Description

含噻唑基雷帕霉素类衍生物及其应用 技术领域
本发明属于医药技术领域,涉及新的雷帕霉素类衍生物、其光学活性体及其药学上可接受的盐,包括它们的制备方法以及含有所述化合物的药物组合物。本发明还涉及该化合物及其衍生物用于制备治疗和/或预防癌症的药物中的用途。
背景技术
恶性肿瘤严重危害人类健康。全球每年肿瘤新发病人数超过1200万人,我国每年因恶性肿瘤死亡的人数约有130万人。现有抗肿瘤药物的临床应用使肿瘤在一定程度上得到了抑制,然而,对危害人类生命健康最严重的恶性肿瘤的治疗仍未能达到满意的效果。面对巨大的用药人群,急需开发新型靶向抗肿瘤药物。
雷帕霉素(rapamycin)是由吸水链霉菌FC904(Streptomyces hygroscopicus FC904)发酵产生的多功能药物,现称西罗莫司(sirolimus)。雷帕霉素是大环内酯类化合物,作为器官移植抗排斥药物应用于临床,后来又作为治疗冠状动脉再狭窄的药物涂层支架应用于临床;它是哺乳动物细胞内丝氨酸/苏氨酸蛋白激酶mTOR(mammalian target of rapamycin,哺乳动物雷帕霉素靶位)抑制剂。mTOR作为细胞生长增生的中心调控者,人体多种肿瘤细胞中可见mTOR通路的失调,以其为靶点开发的mTOR抑制剂可有效抑制肿瘤细胞增殖、诱导肿瘤细胞凋亡和逆转细胞毒药物耐药性。因此,雷帕霉素的多个化学半合成衍生物现已由FDA批准应用于晚期 癌症的治疗;其中代表性的药物有:惠氏制药(Wyeth)开发的Temsirolimus(CCI-779),已被FDA批准治疗晚期肾癌;诺华公司(Novartis)研发的Everolimus,于2009年被FDA批准用于晚期肾癌治疗。Deferolimus为Ariad公司研发,无免疫抑制活性。该药于2005年由FDA经快速审批通道批准用于治疗软组织和骨骼恶性肿瘤。近年来又发现它具有延长哺乳动物寿命的作用,有十分广阔的应用前景。
相关研究表明,在上述西罗莫司衍生物中,以C40位经化学半合成方法得到的衍生物抗肿瘤活性突出,且免疫抑制活性较低,本发明人在参考文献的基础上,设计合成了一系列雷帕霉素类衍生物,经体外免疫抑制活性测试和抗肿瘤活性筛选,结果表明具有无或低免疫抑制活性且具有强抗肿瘤活性。

表2实施例化合物体外免疫抑制活性
Figure PCTCN2014093929-appb-000008
以雷帕霉素为对照药,采用LTT法检测结果表明,雷帕霉素新衍生物实施例1到实施例5的免疫活性较阳性对照药雷帕霉素显著降低,实施例1和实施例2在不同浓度梯度其无免疫抑制活性,实施例3在低浓度无免疫抑制活性,而高浓度较雷帕霉素活性显著降低。实施例4和实施例5的免疫活性较雷帕霉素弱。
由于实施例化合物表现出低或无的免疫抑制活性,因此我们按照本发明的上式I的雷帕霉素类衍生物进行了体外抗肿瘤活性筛选。
体外抗肿瘤活性测试
(1)将***细胞CasKi、肾癌细胞SK-NEP-1、人白血病细胞HL-60、人恶性黑色素瘤细胞A-375、人鼻咽癌细胞CNE2和人胃癌细胞7901细胞 株复苏并传代2-3次,使细胞活力稳定以用于体外细胞活性测试。悬浮细胞不需消化,贴壁细胞胰蛋白酶(0.25%)进行消化,加入含血清的细胞培养液终止消化,用移液管转移细胞液至离心管,1500r/min下离心3min,轻轻弃去上清液后加入5mL培养液,吹打混匀细胞,计数,贴壁细胞5000-10000个/孔,悬浮细胞20000个/孔,加入96孔板,于37℃、5%CO2培养,细胞培养24小时后加入测试药物。
(2)用二甲基亚砜溶解受试样品作为母液,然后用细胞培养液稀释受试样品:取10ul样品母液,加入990ul细胞培养液,稀释样品至测试浓度。将样品稀释液加入已经在96孔板中培养24h的细胞培养液中,每个浓度加入3孔,设空白对照(未加药物处理)。将96孔板于37℃、5%CO2继续培养72h,在每孔中加入MTT(四氮唑)(5mg/mL)20μL,放入培养箱中4h后,悬浮细胞于4000r/min离心10min,弃去上清液,加入二甲基亚砜150μL,使存活细胞与MTT反应产物甲臜充分溶解,放入酶标仪中测定结果,通过Bliss法可求出药物IC50值,化合物对肿瘤细胞株的IC50(μmol/L)见表3。

注:-表示未测活性。
从上述试验结果可以清楚地看出,本发明所要保护的通式I的化合物,具有无免疫抑制活性或低免疫抑制活性,且表现出较优异的抗癌活性,其实施例化合物对多数癌株的抗肿瘤活性强于雷帕霉素。其实施例2无免疫活性,但对SK-NEP-1的抗肿瘤活性较雷帕霉素提高30倍左右,因此本发明的化合物具有很好的潜在应用前景,有较大可能开发出无或低免疫抑制活性,但抗肿瘤活性强的新型雷帕霉素类候选化合物。
如前所述,本发明实施例化合物对***、肾癌、白血病、黑色素瘤、鼻咽癌或胃癌在内的广泛的癌症具有较强的抗癌活性,在治疗实体瘤和非实体瘤方面都具有良好的应用前景。
