Abstract

本发明涉及药物化学领域,具体涉及一类含有内酰胺的化合物及其衍生物,特别是涉及一种如通式(I)所示吡啶类衍生物、其制备方法及其作为Xa因子抑制剂的用途。本发明进一步涉及上述化合物及其衍生物在制备抗凝药物中的医药用途,特别是在制备预防或治疗血栓形成或栓塞药物中的用途。

Description

一种吡啶类衍生物及其医药用途 技术领域
本发明涉及药物化学领域,具体涉及一类含有内酰胺的化合物及其衍生物作为Xa因子(Factor Xa,在下文也简写为FXa)的抑制剂,进一步涉及上述化合物及其衍生物在制备抗凝药物方面的医药用途。本发明特别涉及一种吡啶类衍生物、其制备方法及其在制备预防或治疗血栓形成或栓塞的药物中的用途。
背景技术
血栓性疾病是严重危害人类健康的疾病,根据血栓形成部位、条件与性质,主要分为动脉血栓与静脉血栓。动脉血栓形成是从动脉血管壁动脉粥样硬化病变与血小板激活开始,其导致的严重临床反应主要为急性心肌梗死、脑卒中;静脉血栓由静脉血管中多种原因诱发形成,可导致静脉血栓栓塞(venous thromboembolism,VTE),其主要临床表现为深静脉血栓形成(deep venous thrombosis,DVT)和肺栓塞(pulmonary embolism,PE)。VTE是继急性冠脉综合征与脑卒中之后的第三大心血管疾病。在医院所有死亡病例中,VTE约占10%,欧盟6国中每年症状性VTE发生总数100万,死亡病例数超过艾滋病、乳腺癌、前列腺癌及交通事故造成死亡的总和。美国死亡病例则超过29.6万/年,而致死性PE在死亡前仅有不到50%得到确诊。国际上的相关指南已将预防VTE列为降低住院患者死亡率最重要的策略之一。
大规模临床试验证据显示,抗凝治疗可阻止血栓的蔓延和复发,并进一步降低卒中、PE等的发生率和死亡率。因此,抗凝治疗已成为目前临床预防和治疗血栓栓塞性疾病的核心和基础,而抗凝药物的研发也始终是新药研发的热点,尤其是以Xa因子抑制剂为靶点的药物研发。
