本发明涉及含有式(I)化合物及其药物上可接受的盐的新的萘膦酸脲衍生物,在式(I)中,相同的m和n分别是整数1-4;相同的p和q分别是整数1-3;相同的R基团分别是游离的或酯化的膦酸基。
Description
本发明涉及新的萘膦酸脲衍生物,它们的制备方法,包含它们的药物组合物以及它们在医学上的应用。
在国际申请PCT/EP91/00014中公开了多—4—氨基—2—羧基—1—甲基—吡咯化合物的脲衍生物。
现已发现,新萘膦酸衍生物和一种选择范围很窄的新萘膦酸——属于PCT/EP91/00014通式范围,但在其中没有具体公开——具有非常有价值的生物性质。
游离的,盐化的或酯化的膦酰基〔(HO)2PO—基〕可以在萘基的一个或两个苯基部分上。
取代的萘基优选1—,2—,3—或4—萘基,典型的是3—或4—萘基。当萘基被三个游离的,酯化的或盐化的膦酸基取代时,膦酸取代基优选在1—、5—和7—,2—、5—和6—或2—、5—和7—位。当它们被两个游离的,酯化的或盐化的膦酸基取代时,膦酸取代基优选在1—和5—,1—和6—,1—和7—或5—和7—位。当它们被一个游离的,酯化的或盐化的膦酸基取代时,膦酸取代基优选在1—、3—、5—或6—位。本发明还包括式(I)化合物所有可能的异构体,立体异构体,它们的混合物以及代谢物和代谢前体或生物前体。
如上所述,本发明也包括式(I)酸的酯以及药物上可接受的盐。
每个膦酰基(HO)2PO—的两个酸功能团中只有一个或两个可以被盐化和/或酯化。
本发明盐中,优选每个膦酰基的两个酸功能团中只有一个被盐化,而在本发明酯中,优选每个膦酰基的两个酸功能团中有两个被酯化。

药物上可接受的盐的例子有与无机碱如钠,钾,钙和铝氢氧化物形成的那些盐,或与有机碱如赖氨酸,精氨酸,N—甲基葡胺,三乙胺,三乙醇胺,二苄胺,甲基苄胺,二—(2—乙基—己基)—胺,哌啶,N—乙基哌啶,N,N—二乙氨基乙胺,N—乙基吗啉,β—苯乙胺,N—苄基—β—苯乙胺,N—苄基—N,N—二甲胺和其它可接受的有机胺形成的那些盐。其中钠和钾盐是优选的。
如上所述,本发明还包括式(I)化合物的药物上可接受的生物前体(也可称作药物前体),即,不同于上述式(I)但给人服用时在体内直接或间接地转化成式(I)化合物的化合物。
优选的式(I)化合物是其中m和n为2;p和q为2;相同的R基团为游离的或C1—C6烷基或苯基—C1—C6烷基酯化的膦酸基化合物及其药物上可接受的盐。

药理学
根据本发明,式(I)的新萘膦酸及其药物上可接受的盐是血管形成抑制剂,例如,根据Folkman方法〔Nature,297,307(1982)〕,已经发现它们在绒毛膜尿囊膜试验中具有活性。因此,本发明化合物可用于治疗哺乳动物(包括人类)的新血管生长,如在慢性炎症,糖尿病患者的视网膜病,牛皮癣,类风湿关节炎和肿瘤生长中有害时的一些病理学疾病。特别是在癌症治疗中,本发明化合物可以单独或同抗肿瘤药物如阿霉素,4'—碘阿霉素,甲氧基—吗啉代—阿霉素,鬼臼乙叉甙,氟尿嘧啶,苯丙氨酸氮芥,环磷酰胺,博来霉素,长春碱或丝裂霉素一起使用。
已经发现本发明化合物也具有TNFa—中和活性,因此它们可用于治疗和预防人的已知是TNF起有害作用的任何疾病状态。典型的这种疾病状态为恶病质,败血病患者的休克,移植排异疾病,AIDS,脑型疟,类风湿关节炎。例如,通过人TNFa在未处理的小鼠LM细胞上抑制细胞毒性活性试验中本发明化合物是有活性的事实,证明本发明化合物具有TNFa—抑制活性。因此,本发明的新化合物可以用作血管形成抑制剂和/或TNFa—中和活性剂。本发明化合物可用于制备治疗血管形成和/或预防和/或治疗其中TNFa起有害作用的疾病状态的药物。在这些治疗应用中,本发明化合物可通过通常途径给药,例如,非肠道,如静脉注射或输注,肌内,皮下,局部或口服给药。剂量取决于患者的年龄,体重和疾病以及给药途径。
例如,对于成人适宜的给药剂量约为每剂量0.5—300mg,每天1—4次。
而且,已经发现本发明化合物可直接用作抗慢病毒剂,特别是抗人免疫缺陷病毒(HIV)。例如,已经发现本发明代表性化合物羰基双—3—({4—〔(4—氨基吡咯—1—甲基—2—羰基)氨基〕—1—甲基吡咯—2—羰基}氨基)—萘—1,5—二膦酸;和羰基双—4—({4—〔(4—氨基吡咯—1—甲基—2—羰基)氨基〕—1—甲基吡咯—2—羰基}氨基)—萘—1,7—二膦酸在J.Natl.Cancer Inst.81,557—586(1989)所述试验中是有活性的。
因此通过给患者服用有效量的本发明化合物的方法可治疗慢病毒感染。在这种方法中,本发明化合物可用于治疗属于慢病毒,特别是人免疫缺陷病毒,尤其是HIV—1或HIV—2的感染。
本发明化合物也可用于制备用于治疗慢病毒感染的药物。所述药物可用作抗慢病毒剂,例如抗HIV—1或HIV—2剂。所述药物也可用于改善慢病毒感染患者的由慢病毒诱发的综合症。
特别是本发明化合物可用于制备用于治疗患者的由于慢病毒,特别是HIV感染的血清阳性,紧张或病理学疾病,或某些诱发疾病,例如淋巴结病综合征(LS),AIDS相关综合征(ARC),AIDS或Kaposi肉瘤。因此可以改善或改进患者的状况。
在这些治疗应用中,本发明化合物可通过通常途径给药,例如,非肠道,如静脉注射或输注,肌内,皮下,局部或口服给药。静脉注射和输注是优选的。剂量取决于患者的年龄,体重和状况以及给药途径。本发明的化合物,例如羰基双—3—({4—〔(4—氨基吡咯—1—甲基—2—羰基)氨基〕—1—甲基吡咯—2—羰基}氨基)—萘—1,5—二膦酸或其药物上可接受的盐,适合成人给药的剂量为每剂量0.5—300mg,每天1—4次。
本发明化合物可用于治疗上述病理学疾病,包括分开或几乎同时施用含有式(I)化合物或其药物上可接受的盐的组合物,和含有不同药物活性成分的药物组合物。因此本发明进一步提供一种用于治疗患有慢病毒感染,特别是HIV感染的病人的含有式(I)化合物或其药物上可接受的盐,和作为结合制剂分开,相继或持续使用的第二种活性剂的产品。第二种活性剂一般是是对HIV—引发疾病的发病机理有影响的药物。
例如,本发明化合物可以同各种活性剂,特别是对逆转录酶,抗微生物剂和抗肿瘤剂或它们两个或多个的混合物有作用的那些成分一起使用。感兴趣的药物包括非核苷逆转录酶抑制剂,如nevi-rapine;核苷衍生物如叠氮胸苷和didanosine;无环鸟苷;三唑核苷;抗坏血酸;蛋白酶抑制剂;细胞素如IL—1,IL—2,IL—3或IL—4;生长因子;干扰素如α—或γ—干扰素;抗肿瘤剂如阿霉素,柔红霉素,表阿霉素,4'—碘阿霉素,甲氧基—吗啉代—阿霉素,去甲氧柔红霉素,鬼臼乙叉甙,氟尿嘧啶,苯丙氨酸氮芥,环膦酰胺,博来霉素,长春碱和丝裂霉素;免疫调节剂,特别是免疫兴奋剂,γ球蛋白,免疫球蛋白和单克隆抗体产物,抗生素和抗微生物产物。典型地,抗微生物剂可以包括青霉素连同氨基葡苷(如庆大霉素,妥布霉素)。然而,一些人们熟知的其它药剂如头孢霉素也可以使用。
这些药物的给药剂量依赖于各病人的病情。因此,剂量范围必须适合于病人的状况,反应和常规治疗方式中所采取的相应的治疗等具体情况,还必须根据病情和/或其它临床情况的变化及时调节药量。
用于本发明的药物组合物可以含有作为活性成分的式(I)化合物或其药物上可接受的盐,再加上一个或多个药物上可接受的赋形剂和/或载体。该药物组合物可以下列常规方法制备并以药物上适当形式给药。例如,静脉内注射或输注溶液可以包含载体如无菌水或优选可为无菌水等渗盐水溶液形式。用于肌肉内注射的悬浮液或溶液可以包含活性化合物和药物上可接受的载体,例如无菌水,橄榄油,油酸乙酯,二醇类如丙二醇,和,如果需要,适量的盐酸利多卡因。
在局部应用,例如用于皮肤病治疗的乳油,洗液或软膏等形式中,活性成分可以同常规油状或乳化赋形剂混合使用。
固体口服形式,例如片剂和胶囊,可以包含活性化合物和稀释剂如乳糖,葡萄糖,蔗糖,纤维素,玉米淀粉和马铃薯淀粉;润滑剂如硅石,滑石粉,硬脂酸,硬脂酸镁或硬脂酸钙,和/或聚乙二醇;粘合剂如淀粉,阿拉伯胶,明胶,甲基纤维素,羟甲基纤维素,聚乙烯基吡咯烷酮;分散剂如淀粉,藻酸,藻酸盐,淀粉乙二醇钠;泡腾混合物;着色剂;甜味剂;润湿剂如卵磷脂,聚山梨酸酯,硫酸月桂酯(laurylsul-phates)。总之,无毒和无药理活性物质均可以用于药物制剂。所说药物制剂可以用已知的方法,例如通过混合,制粒,压片,包糖衣或薄膜衣等方法来制造。
