Description
本申請要求申請日為2021年8月11日的中國專利申請202110919812.6、申請日為2021年10月12日的中國專利申請202111188963.5和申請日為2022年8月1日的中國專利申請202210918443.3的優先權。本申請引用上述中國專利申請的全文。
本發明屬於涉及藥物化學領域,更具體而言,涉及一類新型萘啶類衍生物,及其製備方法和該類化合物的用途。
ATR(Ataxia telangiectasia and Rad3-related protein)是一類參與基因組穩定性及DNA損傷修復的蛋白激酶,屬於PIKK家族成員。ATR的激活可被停滯的複製叉或者DNA單鏈損傷(SSB)所激活。激活的ATR將招募修復蛋白或修復因子對受損部位進行修復,延緩有絲分裂過程(特別在有絲分裂的G2/M期),既穩定了複製叉,又保障了基因組的穩定性。
此外,大部分腫瘤細胞中的DNA損傷修復系統異常,通常缺失一定的修復通路(如P53或ATM的突變),使得其更加依賴ATR來存活。而在正常細胞中,由於其健全完整的修復通路,單獨抑制ATR激酶不會產生較大影響。因此,抑制ATR可能對癌症的治療具有更加顯著的效果,而對於正常細胞則不會產生較大毒副作用。
細胞週期S期中出現的DNA損傷修復主要由ATR通路完成,說明ATR對於保證細胞增殖非常重要。對於臨床腫瘤樣品的分析結果表明在多種腫瘤組織中,例如胃癌、肝癌、結直腸癌、卵巢癌、胰腺癌等,均觀察到ATR表達水平升高。並且在卵巢癌、胰腺癌病人中,高水平的ATR往往伴隨著較低的存活率。
而且,ATR的抑制可同時與放療或化療藥物聯用來協同增強效果。廣泛的化療藥物包括抗代謝藥(如吉西他濱),DNA交聯劑(如順鉑、卡鉑)、烷化劑(如替莫唑胺)、拓撲異構酶抑制劑(如伊利替康)等。腫瘤細胞在收到化療或放療的影響時,會較大程度上激活ATR訊號通路來修復受損的DNA。因此,利用放療或化療藥物治療癌症時,同時對ATR進行抑制,可使得癌症的治療效果大大增強。基於以上的研究,可見ATR是一個重要的有效的腫瘤治療的靶標。
目前,阿斯利康公司的AZD6738、默克公司的VE822以及拜爾公司的BAY1895344等化合物均已進入I/II期臨床研究。

化合物的進一步形式
“藥學上可接受”這裡指一種物質,如載體或稀釋液,不會使化合物的生物活性或性質消失,且相對無毒,如,給予個體某物質,不會引起不想要的生物影響或以有害的方式與任何其含有的組分相互作用。
術語“藥學上可接受的鹽”指一種化合物的存在形式,該形式不會引起對給藥有機體的重要的刺激,且不會使化合物的生物活性和性質消失。在某些具體方面,藥學上可接受的鹽是通過通式(1)化合物與酸反應獲得,如鹽酸、氫溴酸、氫氟酸、硫酸、磷酸、硝酸、碳酸等無機酸,甲酸、乙酸、丙酸、草酸、三氟乙酸、丙二酸、琥珀酸、富馬酸、馬來酸、乳酸、蘋果酸、酒石酸、檸檬
酸、苦味酸、甲磺酸、苯磺酸、對甲苯磺酸等有機酸以及天冬胺酸、麩胺酸等酸性胺基酸。
應理解藥學上可接受的鹽的參考包括溶劑添加形式或結晶形式,尤其是溶劑化物或多晶型。溶劑化物含有化學計量或非化學計量的溶劑,且是在與藥學上可接受溶劑如水,乙醇等,結晶化過程中選擇性形成的。當溶劑是水時形成水合物,或當溶劑是乙醇時形成醇化物。通式(1)化合物的溶劑化物按照本文所述的方法,很方便的制得或形成。舉例說明,通式(1)化合物的水合物從水/有機溶劑的混合溶劑中重結晶而方便的制得,使用的有機溶劑包括但不限於,四氫呋喃、丙酮、乙醇或甲醇。此外,在此提到的化合物能夠以非溶劑化和溶劑化形式存在。總之,對於在此提供的化合物和方法為目的,溶劑化形式被認為相當於非溶劑化形式。
在其他具體實施例中,通式(1)化合物被製備成不同的形式,包括但不限於,無定形,粉碎形和毫微-粒度形式。此外,通式(1)化合物包括結晶型,也可以作為多晶型。多晶型包括化合物的相同元素組成的不同晶格排列。多晶型通常有不同的X-射線衍射光譜、紅外光譜、熔點、密度、硬度、晶型、光和電的性質、穩定性和溶解性。不同的因素如重結晶溶劑,結晶速率和貯存溫度可能引起單一晶型為主導。
在另一個方面,通式(1)化合物可能存在手性中心和/或軸手性,並因此以消旋體、外消旋混合物、單一對映體、非對映異構體化合物和單一非對映體的形式、和順反異構體的形式出現。每個手性中心或軸手性將獨立地產生兩個旋光異構體,並且所有可能的旋光異構體和非對映體混合物以及純或部分純的化合物包括
在本發明的範圍之內。本發明意味著包括這些化合物的所有這種異構形式。
本發明的化合物可以在一個或多個構成該化合物的原子上包含非天然比例的原子同位素。例如,可用放射性同位素標記化合物,比如氚(3H)、碘-125(125I)和C-14(14C)。又例如,可用重氫取代氫原子形成氘代化合物,氘與碳構成的鍵比普通氫和碳構成的鍵更堅固,相比於未氘代藥物,通常氘代藥物具有降低毒副作用、增加藥物穩定性、增強療效、延長藥物體內半衰期等優勢。本發明的化合物的所有同位素組成的變換,無論放射性與否,都包含在本發明的範圍之內。
術語
