Definitions

  • the present invention relates to a solid form, crystal form and preparation method of a compound represented by formula (I) as a small molecule BRD4 inhibitor, and to its application in the preparation of drugs for treating BRD4-related diseases.
  • Histone acetylation can regulate gene transcription and chromosome structure, and play an important role in epigenetics.
  • BET (bromodomain and extra-terminal domain) protein as the "reader" of histone acetylation recognition genes, can specifically interact with acetylation.
  • the modified lysine binds and recruits other transcription factors, forms a mediator complex by participating in protein-protein interactions, phosphorylates RNA polymerase, and activates downstream genes such as c-Myc for gene transcription regulation.
  • Cancer cell proliferation is highly dependent on specific genes (such as c-Myc), and the enhancement of specific gene expression plays an important role in cancer cell proliferation. Studies have shown that the excessive dependence of tumor cells on specific genes makes them very sensitive to BET inhibitors. The presence of BET inhibitors prevents the binding of BET protein to the acetylated lysine of histones, thereby blocking the expression of Myc by transcription factors and inhibiting tumor growth.
  • the BET protein family contains 4 members: BRD2, BRD3, BRD4 and BRDT. Each member includes two N-terminal tandem (BD1 and BD2), an extra terminal group (ET), and several groups of conserved regions (A , B, SEED region) and a C-terminal region (CTM). Among them, the most widely studied is BRD4.

Description

固体形式的BRD4抑制剂化合物及其制备方法与应用 技术领域
本发明涉及一种作为小分子BRD4抑制剂的式(I)所示化合物的固体形式、晶型及其制备方法,并涉及其在制备治疗BRD4相关病症的药物中的应用。
背景技术
组蛋白乙酰化可以调控基因转录及染色体结构,在表观遗传中起到重要作用,BET(bromodomain and extra-terminal domain)蛋白作为组蛋白乙酰化识别基因的“reader”,能特异性与乙酰化修饰的赖氨酸结合,并招募其它转录因子,通过参与蛋白与蛋白相互作用形成介体复合物、磷酸化RNA聚合酶,进而激活基因转录调控c-Myc等下游基因。癌细胞增殖高度依赖于特定的基因(如c-Myc),特定基因表达的增强对癌细胞的增殖起到重要的作用。研究表明,肿瘤细胞对于特定基因的过度依赖性,使得它们对BET抑制剂非常敏感。BET抑制剂的存在,阻碍了BET蛋白与组蛋白乙酰化的赖氨酸结合,从而阻断了转录因子对Myc的表达抑制了肿瘤的生长。
BET蛋白家族包含4个成员:BRD2、BRD3、BRD4和BRDT,每个成员都包括两段N-末端串联(BD1和BD2),一段额外的末端基团(ET),几组保守的区域(A,B,SEED区域)和一个C-末端区域(CTM)。其中研究最多最广的是BRD4,目前研究发现许多血液肿瘤包括淋巴瘤(例如急性骨髓淋巴瘤等)、白血病(例如急性成淋巴细胞性白血病等)、骨髓瘤(例如多种骨髓瘤等)及神经细胞瘤、胶质瘤、乳腺癌(例如三阴乳腺癌等)、胃肠肿瘤(例如结直肠癌等)及***癌等实体瘤的发生都与BRD4的过度表达有关,但目前还没有以BRD4为靶点的药物上市。

3.3肿瘤测量和实验指标
实验指标是考察肿瘤生长是否被抑制、延缓或治愈。每周两次用游标卡尺测量肿瘤直径。肿瘤体积的计算公式为:V=0.5a×b 2,a和b分别表示肿瘤的长径和短径。
化合物的抑瘤疗效用TGI(%)或相对肿瘤增殖率T/C(%)评价。TGI(%),反映肿瘤生长抑制率。TGI(%)的计算:TGI(%)=【(1-(某处理组给药结束时平均瘤体积-该处理组 开始给药时平均瘤体积))/(溶媒对照组治疗结束时平均瘤体积-溶媒对照组开始治疗时平均瘤体积)】×100%。
相对肿瘤增殖率T/C(%):计算公式如下:T/C%=T RTV/C RTV×100%(T RTV:治疗组RTV;C RTV:阴性对照组RTV)。根据肿瘤测量的结果计算出相对肿瘤体积(relative tumor volume,RTV),计算公式为RTV=V t/V 0,其中V 0是分组给药时(即d 0)测量所得平均肿瘤体积,V t为某一次测量时的平均肿瘤体积,T RTV与C RTV取同一天数据。
