Abstract
本發明涉及作為CDK抑制劑的大環化合物、其製備方法及其在醫藥上的應用。具體而言,本發明涉及一種通式(I)所示的新的大環化合物、其製備方法及含有該化合物的醫藥組成物以及其作為治療劑,特別是作為CDK抑制劑的用途以及用於治療癌症、炎症、病毒感染、心臟肥大或HIV的用途,其中通式(I)的各取代基與說明書中的定義相同。
Description
本發明涉及屬於醫藥領域,涉及一種通式(I)所示的新的大環化合物、其製備方法及含有該衍生物的醫藥組成物以及其作為治療劑,特別是作為CDK抑制劑在治療過度增殖性疾病中的用途。
近年來,腫瘤已超越心血管疾病,成為全球第一大死亡疾病,抗腫瘤藥物研究具有重要的學術和現實意義。過度活化、持續的細胞增殖是腫瘤的一個基本特徵,因此誘導細胞週期阻滯可有效抑制腫瘤的生長。細胞週期蛋白依賴性激酶(cyclin dependent kinase,CDK)屬於絲/蘇胺酸蛋白激酶家族,是參與細胞週期調節的關鍵激酶。目前已報導有20個不同的CDK,根據CDK功能的不同,可以將其主要分為兩大類。一類CDK參與細胞週期調控,主要包括CDK1、CDK2、CDK4、CDK6等。另一大類CDK參與轉錄調節,主要包括CDK7、CDK8、CDK9、CDK10、CDK11等。在腫瘤細胞中,細胞週期蛋白(cyclin)過表達或過度活化、
CDKI活性被抑制、上游分裂信號持續激活等都會引起CDK的活性改變。CDK活性失調會直接或間接引起細胞增殖失控、基因組不穩定(DNA突變增加,染色體缺失等)和染色體不穩定(染色體數目變化)等,參與腫瘤的發生發展。由於CDK活性為細胞分裂所必需,而在腫瘤細胞中又常有CDK活性增強,因此長期以來,CDK一直被認為是抗腫瘤及其他增殖失調疾病藥物研發的較好靶點。
LY2835219(也稱作Bemaciclib或Abemaciclib)是由禮來(Eli Lilly)公司開發的一種以抑制細胞週期依賴性激酶4和6(CDK4/6)為機理的乳腺癌治療藥物。其結構式為。一期臨床數據表明該藥單藥治療轉移性乳腺癌患者早期療效較好,尤其對於那些激素受體陽性的乳腺癌患者,臨床獲益率可達61%,這意味著患者疾病控制的時間超過了24周,或腫瘤大小下降30%以上。目前,美國FDA已經批准禮來(Eli Lilly)的波瑪西林(Abemaciclib)(VERZENIO)聯合非甾體芳香酶抑制劑(non-steroidal aromatase inhibitors,NSAI)來曲唑或阿那曲唑用於一線治療絕經後激素受體(HR)陽性,人表皮生長因子受體2(HER2)陰性的晚期或轉移性乳腺癌。非小細胞肺癌的臨床研究也已開始。
PD0332991(也稱作Ibrance或帕博西林(Palbociclib))是由輝瑞(Pfizer)公司開發的CDK4/6抑制劑。其結構式為
。2015年2月3日,FDA加速批准了PD0332991的上市申請,與來曲唑聯用治療雌激素受體(ER)陽性、人表皮生長因子受體2(HER2)陰性的絕經後婦女轉移性乳腺癌。
CDK抑制劑也可用於治療心血管病症如再狹窄和動脈粥樣硬化和由異常細胞增殖所致的其他血管病症。細胞週期蛋白依賴性激酶抑制劑蛋白的過表達抑制氣囊血管成形術之後的血管平滑肌增殖和內膜增生。而且,嘌呤CDK2抑制劑CVT-313(Ki=95nM)使得大鼠新內膜生成的抑制大於80%。
CDK抑制劑可用於治療由多種感染性物質引起的疾病,包括真菌、原生動物寄生蟲如惡性瘧原蟲和DNA與RNA病毒。
最近,CDK9與HIV複製的預防有關,因此新CDK生物學的發現繼續湧現出CDK抑制劑的新治療適應症。
CDK在嗜中性粒細胞介導的炎症中非常重要,且CDK抑制劑促進動物模型中炎症的消退。因此,包括CDK9抑制劑的CDK抑制劑可用作抗炎劑。
選擇性CDK抑制劑可用於改善各種自身免疫性病症的影響。慢性炎性疾病-類風濕性關節炎的特徵為滑液組織增生;滑液組織增殖的抑制應將炎症降到最小並預防關節破壞。在大鼠關節炎模型中,藉由用表達CDK抑制劑蛋白p16的腺病毒治療而基本上抑制了關節腫痛。CDK
抑制劑對抗細胞增殖的其他病症是有效的,包括銀屑病(其特徵為角質化細胞過度增殖)、腎小球腎炎、慢性炎症和狼瘡。
目前已有的CDK抑制劑專利申請包括,如WO2015101293A1、WO2016015605A1、WO2016194831A1、WO2008079933A2等等。由於巨大的市場需求,所以仍有必要繼續研發低毒、高效的CDK抑制劑。
大環素已被公認為藥物發現中的重要結構類別。對於相同數量的重原子,大環化合物本身具有比其非環狀類似物更少數量的可旋轉鍵,這是口服生物利用度的有益特徵(Mallinson,J.;Collins,I.Macrocycles in new drug discovery.Future Med.Chem.2012,4,1409-1438)。結果,大環化合物比其非環狀類似物更具構象限制,這可能賦予更高的靶標結合和選擇性並改善口服生物利用度。
天然產物大環化合物的開發已經產生了幾種腫瘤藥物,這些藥物被批准用於臨床或已經達到後期臨床開發,例如mTOR抑制劑Torisel®(temsirolimus)[Kwitkowski VE,Prowell TM,Ibrahim A et al.FDA approval summary:temsirolimus as treatment for advanced renal cell carcinoma.Oncologist 15(4),428-435(2010)],微管蛋白穩定劑Ixempra®(伊沙匹隆)和Hsp90抑制劑17-烯丙基胺基-格爾德黴素[Mcdonald E,Workman P,Jones K.Inhibitors of the HSP90 molecular chaperone:attacking the master regulator in cancer.Curr.Top.Med.Chem.6(11),1091-1107(2006)]。許多合成大環化合物已進入臨床開發階段,例如雙重JAK2/FLT3抑制劑pacritinib,目前正在進行II期臨床試驗[Hart S,Goh
KC,Novotny-Diermayr V et al.SB1518,a novel macrocyclic pyrimidinebased JAK2 inhibitor for the treatment of myeloid and lymphoid malignancies.Leukemia 25(11),1751-1759(2011)],II期臨床試驗中的CDK2/JAK2/FLT3抑制劑SB1317[William AD,Lee ACH,Goh KC et al.Discovery of kinase spectrum selective macrocycle(16E)-14-methyl-20oxa5,7,14,26-tetraazatetracyclo[19.3.1.1(2,6).1(8,12)]heptacosal(25),2(26),3,5,8(27),9,11,16,21,23-decaene(SB1317/TG02),a potent inhibitor of cyclin dependent kinases(CDKs),janus kinase 2(JAK2),and Fms-like tyrosine kinase-3(FLT3)for the treatment of cancer.J.Med.Chem.55(1),169-196(2012)]和西侖吉肽(cilengitide),一種用於治療膠質母細胞瘤的III期臨床試驗中的合成環肽[Stupp R,Van Den Bent MJ,Erridge SC et al.Cilengitide in newly diagnosed glioblastoma with MGMT promoter methylation:Protocol of a multicenter,randomized,open-label,controlled phase III trial(CENTRIC).J.Clin.Oncol.28(15s),TPS152(2010)]。泛CDK抑制劑化合物M是作為開發候選物提出的合成大環化合物的另一個實例[Hirai H,Takahashi-Suziki I,Shimomura T et al.Potent anti-tumor activity of a macrocycle-quinoxalinone class pan-Cdk inhibitor in vitro and in vivo.Invest.New Drugs 29(4),534-543(2011)]。
