Abstract
本發明涉及橋雜環基取代的嘧啶類化合物及其製備方法和醫藥用途。特別地,本發明涉及通式(I)所示的化合物、其製備方法及含有該化合物的醫藥組成物,及其作為JAK1和TYK2激酶抑制劑的用途,和用於治療與JAK1和TYK2激酶活性相關的疾病,例如炎症、自身免疫性病症、癌症等中的用途。其中通式(I)中的各取代基的定義與說明書中的定義相同。
Description
本發明屬於醫藥技術領域,具體涉及一種橋雜環基取代的嘧啶類化合物、其製備方法及含有其的醫藥組成物,以及其用於調節Janus激酶1(JAK1)和酪胺酸蛋白質激酶2(TYK2)活性並且用於治療和/或預防與JAK1和TYK2活性相關的疾病的用途。
胞內信號傳遞過程是細胞對外界刺激產生反應,並最終引發特異性生物學效應的有效方式。細胞因子能夠藉由多種信號轉導通路進行胞內信號傳遞,從而參與調控造血功能和免疫相關的許多重要的生物學功能。蛋白酪胺酸激酶中的Janus激酶(JAK)家族和轉錄激活子(STAT)在細胞因子信號轉導過程中扮演重要角色(J.Immunol.2015,194,21)。
Janus激酶(JAK)家族在涉及免疫應答的細胞增殖和功能的細胞因子依賴性調解中起著一定的作用。目前,有四種已知的哺乳動物JAK家族成員:JAK1(亦稱Janus激酶-1)、JAK2(亦稱Janus激酶-2)、JAK3(亦稱Janus激酶,白細胞,JAKL1,L-JAK和Janus激酶-3)、Tyk2(亦稱蛋白質-酪胺酸激酶2)。JAK1、
JAK2和Tyk2廣泛存在於各種組織和細胞中,而JAk3僅存在於骨髓和淋巴系統中(J.Med.Chem.2014,57,5023)。
Tyk2是第一個被發現的JAK激酶,在調控IL-12和細菌脂多糖(LPS)的生物學應答反應中起著重要作用,也參與IL-6、IL-10和IL-12介導的信號轉導通路。靶向Tyk2可成為治療IL-12、IL-23、或I型IFN介導的疾病的新策略,該疾病包括但不限於類風濕性關節炎、多發性硬化症、狼瘡、銀屑病、銀屑病性關節炎、炎症性腸炎、葡萄膜炎、結節病、紅斑狼瘡和癌症。
JAK1在調控多種細胞因子受體家族的生物學應答功能中發揮重要的作用。JAK1基因剔除小鼠具有早期的出生後致死因子顯型,神經系統也受到損害,導致幼鼠出現先天缺陷。研究表明JAK1基因剔除小鼠會出現胸腺細胞和B細胞的分泌缺陷,JAK1基因剔除的組織對LIF、IL-6、IL-10的反應明顯減弱。臨床試驗表明JAK1抑制劑在治療類風濕性關節炎、潰瘍性結腸炎、克羅恩病、紅斑狼瘡、斑禿、特應性皮炎等多種炎症和自身免疫性疾病方面都表現出很好的療效。
細胞因子與受體結合後,受體形成二聚體,與受體偶聯的JAK相互靠近並進行酪胺酸殘基磷酸化而活化。進而催化受體本身的酪胺酸殘基磷酸化,形成“停泊位點”。信號轉導和轉錄激活子(Signal Transducer and Activator of Transcription,STAT)是一組能與靶基因調控與DNA結合的胞質蛋白。STAT家族包括STAT1、STAT2、STAT3、STAT4、STAT5a、STAT5b和StAT6。STAT藉由SH2結構域識別“停泊位點”並被JAK激酶對其C端酪胺酸殘基進行磷酸化從而被激活。激活的STAT因子轉入細胞核內,在調節先天性和獲得性宿主免疫反應中發揮重要的作用。
JAK/STAT信號轉導通路的激活促進各種疾病的發生,包括但不限於,許多異常免疫應答,如過敏、哮喘、類風濕性關節炎、肌萎縮性脊髓側
索硬化症和多發性硬化症等。其還與癌症,例如白血病(急性髓性白血病和急性淋巴細胞白血病)、實體瘤(子宮平滑肌肉瘤、前列腺癌)等相關(Curr.Opin.Rheumatol.2014,26,237)。
鑒於JAK1和TYK2在炎症信號通路中扮演的重要角色,能同時抑制這兩種激酶的藥物有進一步提升藥效的潛力,給患者帶來更大的獲益。
本發明人經過潛心研究,設計合成了一系列橋雜環基取代的嘧啶類化合物,並對其進行了JAK1和TYK2活性的篩選,研究結果顯示該類化合物具有突出的JAK1和TYK2抑制活性,並且可以被開發為治療與JAK1和TYK2活性相關的疾病的藥物。
