Definitions
- the present invention relates to certain novel heterocyclic compounds or their pharmaceutically acceptable salts. Such compounds and their salts can be used for the treatment or prevention of many different cancers.
- the present invention also relates to a pharmaceutical composition comprising the compound and its salt, an intermediate in the preparation of the compound, and a method for treating various cancers using the compound and its salt.
- the ras gene is quite conserved in evolution and is widely present in various eukaryotes such as mammals, fruit flies, fungi, nematodes and yeasts, suggesting that it has important physiological functions.
- Various ras genes have similar structures and are composed of four exons, which are distributed on a total length of approximately 30 kb of DNA. Their encoded products are proteins with a relative molecular mass of 21,000, so they are called P21 proteins.
- H-ras is located on the short arm of human chromosome 11 (11p15.1 ⁇ p15.3), K-ras is located on the short arm of chromosome 12 (12p1.1 ⁇ pter), and N-ras is located on the short arm of chromosome 1.
- the sequence of each ras gene encoding P21 is evenly distributed among the four exons, and the sequence and size of the introns are different It is very large, so the whole gene is also very different.
- human K-ras is 35kb long, while N-ras is 3kb long.
- K-ras can be spliced in two ways, but the content of mRNA encoding K-ras-B is high. Except for K-ras-B which contains 188 amino acids, the other two Ras proteins both contain 189 amino acids.
- Ras(P21) protein is located inside the cell membrane, and it plays an important role in transmitting the signal of cell growth and differentiation. It belongs to the guanosine triphosphate (GTP) binding protein (a coupling factor for cell message transmission), which regulates the transmission of information through the mutual conversion of GTP and guanosine diphosphate (GDP).
- GTP guanosine triphosphate
- P21 has a strong affinity with GTP and GDP, and has weak GTPase activity. Under normal circumstances, the combination of P21 and GDP is in an inactive state.
- the growth and differentiation factor outside the cell transmits the signal to the P21 inside the cell membrane, it can enhance the binding activity of P21 and GTP, so that the combination of P21 and GTP becomes an active state, and the signal system is opened. .
- P21 has GTPase activity, it can hydrolyze GTP into GDP. After P21 and GDP are combined, P21 is inactivated and the signal system is closed. Under normal circumstances, the GTPase activity of P21 is very weak. When combined with GTPase activating protein (GAP), its hydrolysis speed can be increased by 10,000 times and P21 is inactivated. The combination of P21 and GDP can activate guanylate-releasing protein (GNRP). GNRP enables P21 to release GDP and bind GTP. Therefore, through the mutual transformation of GTP and GDP, the opening and closing of the signal system of P21 can be regulated in a controlled manner to complete the growth and differentiation signal. A process that is introduced into the cell.
- GAP GTPase activating protein
- More than one-fifth of cancer patients are accompanied by mutations in the Ras gene. These mutations mostly occur on residues G12, G13 and Q61. The mutations lead to GAP protein-mediated failure and the Ras signal is continuously activated; the present invention designs and synthesizes a series of Chemical molecules have strong biological activity of inhibiting ras, and provide a method to treat related cancers by inhibiting H-ras, K-ras or N-ras.
- the present invention provides compounds capable of modulating G12C mutant KRAS, HRAS and/or NRAS proteins, including their stereoisomers, pharmaceutically acceptable salts, tautomers and prodrugs. Also provided are methods of using such compounds to treat different diseases or conditions (such as cancer).

Abstract
式(I)的化合物或其药学上可接受的盐、前药、互变异构体或立体异构体和溶剂化物,这类化合物可用于治疗哺乳动物中癌症和炎症。还公开了式(I)化合物的制备方法以及包含所述化合物的药物组合物。
Description
本发明涉及某些新型杂环化合物或其药学上可接受的盐,此类化合物及其盐可用于很多不同的癌症的治疗或预防。本发明还涉及包含所述化合物及其盐的药物组合物、所述化合物的制备中的中间体、和涉及利用所述化合物及其盐治疗各种不同癌症的方法。
1982年Weinberg和Barbacid首先从人膀胱癌细胞系中分离出一种转化基因,可使NIH 3T3细胞发生恶性转化,而从正常人组织中提取的DNA则无此种作用。随后,Santos与Parada发现上述转化基因并非新型基因,而是Harvery鼠肉瘤病毒ras基因的人类同源基因,命名为H2ras。同年,Krontiris在人肺癌细胞中发现Kirsten鼠肉瘤病毒基因的同系物,称为K-ras。另一种相似的基因是在人神经母细胞瘤DNA感染NIH 3T3细胞时发现的与ras类似的基因,称为N2ras,此种基因和病毒无关.
ras基因在进化中相当保守,广泛存在于各种真核生物如哺乳类,果蝇,真菌,线虫及酵母中,提示它有重要的生理功能.哺乳动物的ras基因家族有三个成员,分别是H-ras、K-ras、N-ras,其中K-ras的第四个外显子有A、B两种变异体。各种ras基因具有相似的结构,均由四个外显子组成,分布于全长约30kb的DNA上。它们的编码产物为相对分子质量2.1万的蛋白质,故称为P21蛋白。已证明,H-ras位于人类11号染色体短臂上(11p15.1~p15.3),K-ras位于12号染色体短臂上(12p1.1~pter),N-ras位于1号染色体短臂上(1p22-p32),除了K-ras第四个外显子有变异外,每个ras基因编码P21的序列都平均分配在四个外显子上,而内含子的序列及大小相差很大,因而整个基因也相差很大,如人K-ras有35kb长,而N-ras长为3kb。由于有两个第四号外显子,K-ras可以两种方式剪接,但编码K-ras-B的mRNA含量高。除K-ras-B含有188个氨基酸外,其他两种Ras蛋白均含有189个氨基酸.
Ras(P21)蛋白位于细胞膜内侧,它在传递细胞生长分化信号方面起重要作用。它属于三磷酸鸟苷(GTP)结合蛋白(一种细胞信息传递的耦联因子),通过GTP与二磷酸鸟苷(GDP)的相互转化来调节信息的传递。P21与GTP和GDP有很强的亲和性,而且有较弱的GTP酶活性。正常情况下P21和GDP结合处于失活状态,当细胞外的生长分化因子把信号传导到胞膜内侧的P21时,可增强P21与GTP结合活性,使P21和GTP结合成为激活状态,信号系统开放。因为P21有GTP酶活性,可使GTP水解成GDP,P21和GDP结合后P21失活,信号系统关闭。正常情况下P21的GTP酶活性很弱,当和GTP酶激活蛋白(GAP)结合后其水解速度可提高1万倍而使P21失活。P21和GDP结合后可以激活鸟苷酸释放蛋白(GNRP),GNRP使P21释放GDP结合GTP,因此通过GTP和GDP的相互转化可以有节制地调节P21对信号系统的开启和关闭,完成生长分化信号传入细胞内的过程.
超过1/5的癌症患者都伴有Ras基因突变,这些突变多发生在G12、G13及Q61残基上,突变导致GAP蛋白介导失灵,Ras信号持续处于激活状态;本发明设计合成了一系列化学分子,具有很强的抑制ras的生物活性,提供了通过抑制H-ras、K-ras或者N-ras来治疗相关癌症的方法。
