Definitions
- the present invention relates to pharmaceutically active compounds, deuterated compounds (hydrogen replaced by deuterium) and pharmaceutically acceptable salts thereof, which can be used to treat or prevent diseases or medical conditions mediated by certain mutant forms of epidermal growth factor receptor ( For example, L858R activating mutant, Exon19 deletion activating mutant, T790M resistance mutant and C797S resistance mutant).
- the present invention also relates to a pharmaceutical composition containing the compound and a method of using the compound, deuterated compound and salt thereof to treat diseases mediated by various forms of EGFR mutants.
- Epidermal growth factor receptor is a transmembrane glycoprotein belonging to the ErbB family of tyrosine kinase receptors. Activation of EGFR leads to autophosphorylation of receptor tyrosine kinases, which initiates a cascade of downstream signaling pathways involved in regulating cell proliferation, differentiation, and survival. EGFR is abnormally activated by various mechanisms, such as receptor overexpression, mutation, ligand-dependent receptor dimerization, ligand-independent activation, and is associated with the development of a variety of human cancers.
- Inhibition of EGFR is one of the key goals of cancer treatment. Although the previous generations of EGFR-TKIs developed rapidly, the problem of drug resistance also appeared along with the development of drugs. Most drug resistance is the T790M mutation of the ATP receptor. Recently developed third-generation irreversible inhibitors against T790M, such as osimertinib, have very good inhibitory activity, but drug resistance will inevitably appear.
- EGFR-C797S mutation is the most common secondary mutation leading to third-generation TKI resistance. C797S is a missense mutation in which cysteine is replaced by serine at position 797 of exon 20 of EGFR. It is located in the tyrosine kinase region of EGFR. The mutation of C797S prevents osimertinib from continuing to form covalent bonds in the ATP binding domain, thus losing Inhibit the effect of EGFR activation, leading to the occurrence of drug resistance.
- the present invention relates to compounds capable of inhibiting EGFR, and these compounds can be used to treat cancer and infectious diseases.

Abstract
式I化合物,使用这些化合物作为EGFR抑制剂的方法,以及包含这些化合物的药物组合物。该化合物可用于治疗、预防或改善诸如癌症或感染的疾病或病症。
Description
本发明涉及药学活性化合物、氘化化合物(氢被氘取代)及其药学上可接受的盐,其可用于治疗或预防通过某些突变形式的表皮生长因子受体介导的疾病或医学病症(例如,L858R激活突变体、Exon19缺失激活突变体、T790M抗性突变体和C797S抗性突变体)。本发明还涉及包含所述化合物的药物组合物和使用所述化合物、氘化化合物及其盐治疗由各种不同形式的EGFR突变体介导的疾病的方法。
表皮生长因子受体(EGFR)是一种跨膜糖蛋白,属于酪氨酸激酶受体的ErbB家族。EGFR的激活导致受体酪氨酸激酶的自磷酸化,其启动参与调节细胞增殖、分化和存活的下游信号传导途径的级联。EGFR被各种机制异常激活,如受体过表达、突变,配体依赖性受体二聚化、配体非依赖性激活,并且与多种人类癌症的发展有关。
抑制EGFR是癌症治疗的关键目标之一。尽管前几代EGFR-TKIs发展迅速,但耐药性问题也伴随着药物的发展而出现。大多数耐药性是ATP受体的T790M突变。最近开发针对T790M的第三代不可逆抑制剂,如osimertinib具有非常好的抑制活性,但不可避免地会出现耐药。EGFR-C797S突变是导致第三代TKI耐药最常见的继发突变。C797S是EGFR 20号外显子797位点上丝氨酸取代了半胱氨酸的错义突变,位于EGFR的酪氨酸激酶区,C797S的突变使得osimertinib无法在ATP结合域内继续形成共价键,从而失去抑制EGFR激活的效果,导致耐药的发生。
早期专利申请WO2018108064、WO2018115218、WO2018181777公开了一系列第四代EGFR抑制剂,但是仍然需要具有更强活性和更好PK的EGFR C797S抑制剂。在本发明中,申请人发现了可以作为第四代EGFR抑制剂的小分子,其活性可以用于治疗癌症和/或感染性疾病。预期这些小分子可用作具有更好稳定性、溶解度、生物利用度、治疗指数和毒性值的药物,这些对于成为促进人类 健康的有效药物至关重要。
