Description
技术领域
本发明涉及医药化学技术领域,特别涉及一类N-(4-甲基-3-((4-(吡啶-3-基)嘧啶-2-基)氨基)苯基)甲酰胺衍生物及制备方法、应用。
背景技术
慢性粒细胞白血病(CML)是一种克隆性造血干细胞紊乱、骨髓增生性疾病,绝大部分病患呈现费城染色体(Ph)为阳性。根据CML的疾病进展,可分为慢性期、加速期和急变期。目前约85%~90%的CML患者在慢性期被诊断确诊,若未及时采取合理的治疗方案,患者会经历加速期在3-4年后迅速恶化至急变期,最终导致患者死亡。
回顾近20年的临床治疗方案,以伊马替尼(商品名:格列卫;化学名:4-[(4-甲基-1-哌嗪基)甲基]-N-[4-甲基-3-[4-(3-吡啶基)-2-嘧啶基]氨基]苯基]苯甲酰胺)为代表的BCR-ABL抑制剂使大多数慢性期CML患者改善长期预后,仅需通过口服药物就能长期缓解病情并使患者接近正常的预期寿命。因此,伊马替尼作为经典的小分子靶向药物,目前作为一种高性价比的治疗方案已分别用于:治疗费城染色体阳性的慢性髓性白血病(Ph+CML)的慢性期、加速期或急变期成人患者,联合化疗治疗新诊断的费城染色体阳性的急性淋巴细胞白血病(Ph+ALL)的儿童患者,治疗复发的或难治的费城染色体阳性的急性淋巴细胞白血病(Ph+ALL)的成人患者,治疗嗜酸粒细胞增多综合征(HES)和/或慢性嗜酸粒细胞白血病(CEL)伴有FIP1L1-PDGFRα融合基因的成年患者,治疗骨髓增生异常综合征/骨髓增殖性疾病(MDS/MPD)伴有血小板衍生生长因子受体(PDGFR)基因重排的成年患者,治疗不能切除和/或发生转移的胃肠间质瘤成人患者,用于对不能切除和/或转移性KIT突变的恶性黑色素瘤患者。
但随着长期用药反馈时发现,仍有少数患者在服用药物的过程中失去了对伊马替尼的有效反应或出现疾病进展快速,并且随着在CML疾病进展后期对伊马替尼的耐药性逐步增加,表现为治疗效果较差或治疗失败,因而继续深入研究具有高活性和安全性的伊马替尼结构衍生物及相关疾病的治疗有着重要意义。
