Description

抗病毒药
技术领域
本发明涉及一种抗病毒药,具体涉及一种具有α-羟基-α,β-不饱酮(keone)作为部分结构的化合物以及一种含有该化合物作为整合酶抑制剂的药物组合物。
背景技术
在各种病毒当中,已知有一种逆转录酶病毒,即人体免疫缺陷病毒(HIV)能够导致获得性免疫缺陷综合征(AIDS)。用于AIDS的治疗药主要选自各种逆转录酶抑制剂(如AZT、3TC)和蛋白酶抑制剂(如茚地那韦),但事实证明它们常伴随着各种副作用,如肾病和出现各种耐药性病毒。因此需要开发出具有其它作用机理的抗HIV药。
另一方面,在Balzarini,J.等,Proc.Natl.Acad.Sci.USA 1996,93,13152-13157页中报道了一种有效用于治疗由于频繁出现耐药性突变体而产生获得性免疫功能丧失综合征的联合疗法。临床上逆转录酶抑制剂和蛋白酶抑制剂用作抗HIV药剂,但具有相同作用机理的药剂常表现出交叉耐药性或仅有附加的活性。因此需要具有其它作用机理的抗HIV药剂。
整合酶抑制剂的例子包括描述于WO99/50245、WO99/62520、WO99/62897、WO99/62513、WO00/39086和WO01/00578中的1,3-二氧代丁酸和1,3-丙二酮。另一种整合酶抑制剂为描述于WO01/17968中的丙烯酸衍生物。最近报道的其它类型为描述于WO2002/30426、WO2002/30930、WO2002/30931和WO2002/36734中的氮杂-或多氮杂萘基甲酰胺衍生物。
一种与本发明化合物的结构相类似的化合物为N-取代的-3-甲酰胺-4-羟基-5-氧代-3-吡咯啉衍生物,其抗炎效果描述于Eur.J.Med.Chemical-Chim.Ther.(1979),14(2),189-190页中。Pharmazie(1997),52(4),276-278页公开了作为中间体的1-甲基-4-芳基脲基-2,3-二氧代吡咯烷衍生物。WO92/06954公开了对醛糖还原酶具有抑制效果的pyrolizine二酮衍生物。J.Med.Chemical(1976),19(1),172-173页公开了具有抗炎效果的N-取代的-4,5-二氧代吡咯烷-3-甲酰苯胺衍生物。Journal of Physical Chemistry A(2002),106(11),2497-2504页公开了嘧啶衍生物,但未提及任何药物用途。
T’ai-wan K’o Hsueh(1997),31(3-4),130-135页公开了3-羟基-7-(苯基甲氧基)-2-(2-喹啉基)-4H-1-苯并吡喃-4-酮。具有“4H-1-苯并吡喃-4-酮”结构的化合物的例子包括描述于以下文献(虽然其中未提及作用机理)中具有抗HIV活性的类黄酮衍生物:①J.Nat.Prod.(2001),64(4),546-548页;②Anticancer Res.(2000),20(4),2525-2536页;③WO98/11889;④Pharmazie(1998),53(8),512-517页。

以下将阐述本发明化合物的用途。
本发明的化合物可用于制备例如抗病毒药剂的药物组合物。本发明化合物对病毒的整合酶具有显著抑制活性,因此可期望其对至少通过受感染动物细胞的整合酶产生而生长的病毒所引起的各种疾病具有预防或治疗的效果,可用作抗逆转录病毒(如HIV-1、HIV-2、HTLV-1、SIV、FIV)的整合酶抑制剂以及抗HIV药剂。
此外,本发明的化合物还可与其它具有不同作用机理的抗HIV药剂(如逆转录酶抑制剂和/或蛋白酶抑制剂)联合使用。由于任何整合酶抑制剂至今尚未售卖,因此本发明化合物与逆转录酶抑制剂和/或蛋白酶抑制剂的联合疗法相当有用。
另外,如在鸡尾酒疗法中所显示的那样,本发明化合物可作为增强其它HIV药剂的抗HIV活性的联合药物。
此外,本发明的化合物还可用于基因疗法中以防止衍生自HIV或MLV的逆转录病毒载体扩散至未受侵害的组织。具体而言,在将体外受载体感染的细胞放置到体内的情况中,提前给予本发明的化合物可以防止身体受到不必要的感染。
本发明的化合物可口服,也可通过胃肠外给药。对于口服的情况,本发明化合物可从任何常规的剂型,例如固体制剂(如片剂、散剂、颗粒剂、胶囊剂);含水制剂;油质混悬剂;溶液剂(如糖浆剂或酏剂)的剂型使用。对于胃肠外给药的情况,本发明的化合物可以含水或油质混悬剂注射剂或滴鼻剂的剂型使用。在制备这些制剂中,可任选采用各种常规的赋形剂、粘合剂、润滑剂、含水溶剂、油质溶剂、乳化剂、悬浮剂、防腐剂、稳定剂等。优选口服药剂作为HIV药剂。
本发明制剂可通过使治疗有效量的本发明化合物与药学上可接受的载体或稀释剂进行混合(如掺合)来制备。可采用众所周知并且容易得到的成分,按照已知的方法制备本发明的制剂。
在制备本发明的药物组合物中,将活性成分与载体掺合或稀释,或者可将其包含在胶囊、sacheier、纸或其它容器形式的载体内。在载体作为稀释剂的情况中,所述载体为起介质作用的固体、半固体或液体材料。因此,本发明的制剂可做成以下形式:片剂、丸剂、散剂、口内药剂、酏剂、混悬剂、乳化剂、溶剂、糖浆剂、气雾剂(固体在液体介质内)和软膏剂。这种制剂可含有最高达10%的活性化合物。优选在给药前配制本发明的化合物。
任何本领域技术人员熟知的适宜载体均可用于所述制剂。在这种制剂中,载体为固体、液体或固体与液体的混合物形式。例如,将本发明的化合物溶解在4%右旋糖/0.5%的柠檬酸钠水溶液中,得到用于静脉注射的2mg/ml浓缩液。固体制剂包括散剂、片剂和胶囊剂。固体载体由一种或多种用作香料、润滑剂、溶解剂、悬浮剂、粘合剂、药片崩解剂、胶囊剂的材料所组成。用于口服的片剂含有适宜的赋形剂(如碳酸钙、碳酸钠、乳糖、磷酸钙等)以及崩解剂(如玉米淀粉、藻酸等)和/或粘合剂(如明胶、阿拉伯胶等)和润滑剂(如硬脂酸镁、硬脂酸、滑石等)。
在散剂药物中,载体为与磨成细粉的活性成分掺合的磨成细粉的固体。在片剂中,使活性成分与具有适宜比率的所需粘合粉末的载体一起掺合,并将其固化成所需的形式和大小。散剂药物与片剂均含有约1%至约99%重量的本发明新型化合物的活性成分。适宜的固体载体包括碳酸镁、硬脂酸镁、滑石、糖、乳糖、果胶、糊精、淀粉、明胶、黄蓍胶、甲基纤维素、羧甲基纤维素钠、低熔蜡和可可脂。
液体制剂包括混悬剂、乳化剂、糖浆剂和酏剂。可将活性成分溶解于或悬浮于药学上可接受的载体(如灭菌水、灭菌有机溶剂、其混合物等)中。通常将活性成分溶解于适宜的有机溶剂(如丙二醇水溶液)内。当将磨成细粉的活性成分分散于含水淀粉、羧甲基纤维素钠溶液或适宜的油时,可制备其它的组合物。
虽然本发明化合物适当的剂量随给药途径、年龄、体重、患者的健康状况和疾病的种类的不同而异,但在口服的情况中,日剂量(成人)可为约0.05-3000mg,优选为约0.1-1000mg。日剂量可分次服用。在胃肠外给药的情况中,日剂量(成人)可为约0.01-1000mg,优选为约0.05-500mg。

试验实施例
通过下述分析方法测定本发明各种化合物对整合酶的抑制活性。
(1)DNA溶液的制备
通过Amersham Pharmacia Biotech合成底物DNA和靶DNA(其序列如下所示)并分别以2pmol/μl和5pmol/μl的浓度溶解于KTE缓冲液(组成:100mM的KCl,1mM的EDTA,10mM的Tris-HCl(pH7.6))中。通过在加热后进行缓慢冷却,使上述DNA溶液与每一种互补序列退火。
(底物DNA)
5’-生物素-ACC CTT TTA GTC AGT GTG GAA AAT CTC TAGCAG T-3’
3’-GAA AAT CAG TCA CAC CTT TTA GAG ATC GTC A-5’
(靶DNA)
5’-TGA CCA AGG GCT AAT TCA CT-Dig-3’
3’-Dig-ACT GGT TCC CGA TTA AGT GA-5’
(2)抑制百分数的计算(受试化合物的IC50值)
将从Vector Laboratories获得的抗生蛋白链菌素以40μg/ml的浓度溶解于0.1M的碳酸盐缓冲液(组成:90mM的Na2CO3,10mM的NaHCO3)中。在4℃下用50μl的上述溶液覆盖微量滴定板(从NUNC获得)的每一个孔过夜后,每一个孔用PBS(组成:13.7mM的NaCl,0.27mM的KCl,043mM的Na2HPO4,0.14mM的KH2PO4)洗涤两次并用300μl的1%脱脂奶的PBS溶液封闭30分钟。另外,每一个孔用PBS洗涤两次,加入50μl用NTE缓冲液(组成:1M的NaCl,10mM的Tris-HCl(pH 8.0),1mM的EDTA)稀释至五十倍的底物DNA溶液(0.04pmol/μl)。微量滴定板在室温下保持30分钟。然后每一个孔用PBS洗涤两次,用H2O洗涤一次。
接着,往按上述制备的每一个孔中加入45μl从12μl缓冲液(组成:150mM的MOPS(pH 7.2),75mM的MnCl2,50mM的2-巯基乙醇,25%的甘油,500μg/ml的牛血清清蛋白-分馏物V)中制备的反应缓冲液、1μl的靶DNA(5pmol/μl)和32μl的蒸馏水。此外,使6μl的受试化合物的DMSO溶液或用于正对照(PC)的DMSO溶液与上述反应缓冲液混合,然后加入9μl的整合酶溶液(30pmol)并进行良好混合。在负对照(NC)的孔中加入9μl的整合酶稀释缓冲液(组成:Hepes(pH 7.6),400mM的谷氨酸钾,1mM的EDTA,0.1%的NP-40,20%的甘油,1mM的DTT,4M的脲)。
将微量滴定板在30℃下培养1小时。取出反应溶液,每一个孔用PBS洗涤两次。随后微量滴定板的每一个孔注满100μl用碱性磷酸酶(绵羊Fab片段:从Boehringer获得)标记的抗洋地黄毒苷抗体,并在30℃下培养1小时。然后每一个孔用0.05%吐温20的PBS溶液洗涤两次,用PBS洗涤一次。接着在每一个孔中加入150μl的碱性磷酸酶反应缓冲液(组成:10mM的对硝基苯基磷酸盐(从VectorLaboratories获得),5mM的MgCl2,100mM的NaCl,100mM的Tris-HCl(pH 9.5))。使微量滴定板在30℃下培养2小时。测定每一个孔在405nm处的光密度(OD),通过以下表达式确定抑制百分数。
抑制百分数(%)=100[1-{(C abs.-NC abs.)/(PC abs.-NC abs.)}]
C abs.:孔的OD
NC abs.:负对照(NC)的OD
PC abs.:正对照(PC)的OD
当在xμg/ml的浓度下抑制百分数(%)为X%,并且在yμg/ml的浓度下抑制百分数(%)为Y%,其中一个为大于50%而另一个小于50%时,通过以下表达式可确定IC50
IC50(μg/ml)=x-{(X-50)(x-y)/(X-Y)}
在下表1中示意了各种化合物的浓度在50%的抑制百分数时的IC50值。化合物在表1中的编号与上述实施例的化合物的编号相同。
