Abstract
具有因子Xa抑制作用的咪唑并[4,5-c]吡啶-4-酮衍生物,本发明涉及式(Ⅰ)的新化合物,其中R,R1,R2,R3,n和p具有如权利要求1中的定义。所述化合物是凝血因子Xa的抑制剂并可用于预防和/或治疗血栓栓塞疾病。
Description
本发明涉及式Ⅰ化合物及其盐:
其中
R是H,具有1-6个碳原子的非支链或支链烷基或具有3-6个碳原子的环烷基,
R1是Ar,
R2是Ar’,
R3是H,R,R4,Hal,CN,COOH,COOA或CONH2,
Ar,Ar’是苯基,萘基或联苯基,每种情况均可未取代或可分别被R,OH,Hal,CN,NO2,CF3,NH2,NHR,NR2,吡咯烷-1-基,哌啶-1-基,苄氧基,SO2NH2,SO2NHR,SO2NR2,-CONHR,-CONR2,-(CH2)n-NH2,-(CH2)n-NHR,-(CH2)n-NR2,-O-(CH2)n-NH2,-O-(CH2)n-NHR,-O-(CH2)n-NR2,R4单-,双-或三-取代或连接-起被-O-(CH2)m-O-取代,
R4是未取代或被-COR,-COOR,OH单取代或被常规的氨基保护基取代的-C(=NH)-NH2,或-NH-C(=NH)-NH2,-C(=O)-N=C(NH2)2,A是具有1-4个碳原子的烷基,Hal是F,Cl,Br或I,m是1或2n是0,1,2或3
p是0或1。
本发明也涉及这些化合物的光学活性形式,外消旋体,非对映异构体和水合物和溶剂化物,如醇化物。
本发明的目的是发现具有有用特性的新化合物,特别是那些可用于生产药物的化合物。
式Ⅰ化合物及其盐被发现具有非常有用的药理活性并具有好的耐受性。特别地,它们具有因子Ⅹa-抑制活性,因此可用于治疗和预防血栓栓塞疾病如血栓形成,心肌梗死,动脉硬化,炎症,中风,心绞痛,血管成形术后的再狭窄和间歇性跛行。
此外,根据本发明的式Ⅰ化合物还是凝血因子因子Ⅶa,因子Ⅸa和血液凝血级联的凝血酶的抑制剂。
具有抗凝血作用芳香脒衍生物公开于,例如EP0540051B1。用于治疗血栓拴塞疾病的环胍化合物公开于,例如WO97/08165。具有因子Ⅹa-抑制活性的芳香杂环公开于例如WO96/10022。作为因子Ⅹa抑制剂的取代的N-[(氨基亚氨基甲基)苯基烷基]氮杂环酰胺公开于WO96/40679。
本发明化合物的抗血栓形成和抗凝血作用是由于其对激活的已知被称为因子Ⅹa的凝血蛋白酶的抑制作用,或对其它激活的丝氨酸蛋白酶如因子Ⅶa,因子Ⅸa或凝血酶的抑制作用。
因子Ⅹa是一种在血液凝血复杂过程中涉及的蛋白酶。因子Ⅹa催化凝血酶原到凝血酶的转化。凝血酶裂解纤维蛋白酶原为纤维蛋白单体,交联后导致初级的血栓形成。凝血酶的激活可以导致血栓栓塞疾病的出现。凝血酶的抑制,因此可以抑制出现在血栓形成中的纤维蛋白的形成
凝血酶的抑制可以测定,例如,通过G.F.Gousins等,在Circulation 1996,94,1705-1712中的方法测定。
因子Ⅹa的抑制可以因此预防血栓的形成。
根据本发明的式Ⅰ化合物及其盐通过对因子Ⅹa的抑制而干扰血液的凝血过程因此抑制血栓的形成。
本发明化合物对因子Ⅹa的抑制和抗凝血和抗血栓活性的测定可以通过常规的体外或体内方法测定。适宜的方法公开于例如J.Hauptmann等Thrombosis and Haemostatis 1990,63,220-223中。
因子Ⅹa的抑制可以测定,例如通过T.Hara等在Thromb.Haemostas.1994,71,314-319中公开的方法测定。
与组织因子结合后,凝血因子Ⅶa引发凝血级联实质部分并激活因子Ⅹ为因子Ⅹa。因子Ⅶa的抑制因此可以预防因子Ⅹa的形成并因而抑制血栓的形成。
本发明化合物对因子Ⅶa的抑制和抗凝血和抗血栓活性的测定可以通过常规的体外或体内方法测定。因子Ⅶa抑制测定的常规方法公开于例如,H.F.Ronning等在Thrombosis Research1996,84,73-81中。
凝血因子Ⅸa产生于真正的凝血级联中并且同样出现在因子Ⅹ到因子Ⅹa的激活中。因子Ⅸa抑制作用可以因此预防因子Ⅹa在其它路径中的形成。
根据本发明的化合物对因子Ⅸa的抑制和抗凝血和抗血栓活性的测定可以通过常规的体外或体内方法测定。适宜的方法公开于例如,J.Chang等在Journal of Biological Chemistry1998,273,12089-12094中的方法。
式Ⅰ化合物可以作为人药和兽药中的药物活性化合物,特别是用于控制和预防血栓栓塞疾病如血栓形成,心肌梗死,动脉硬化,炎症,中风,心绞痛,血管成形术后的再狭窄和间歇性跛行。
