发明领域
本发明涉及半胱氨酸或丝氨酸蛋白酶的新抑制剂,这里将其称作异羟肟酸酯类化合物。本发明还涉及这些新化合物的制造方法及其使用方法。
发明背景
已经证实人的组织中具有很多半胱氨酸和丝氨酸蛋白酶。″蛋白酶″是一种将蛋白质降解成较小组分(肽)的酶。术语″半胱氨酸蛋白酶″和″丝氨酸蛋白酶″是指通过半胱氨酸或丝氨酸残基来区别的蛋白酶,所说的半胱氨酸或丝氨酸残基在催化过程中起决定性作用。包括人在内的哺乳动物体系正常情况下要通过各种酶来分解和加工蛋白质,包括半胱氨酸和丝氨酸蛋白酶。然而,当所存在的含量升高或当不正常失活时,半胱氨酸和丝氨酸蛋白酶可能会陷于病理生理过程。
例如,钙激活的中性蛋白酶(″需钙蛋白酶″)包括一类细胞内半胱氨酸蛋白酶,其无处不在地表现在哺乳动物组织中。已识别出两种主要的需钙蛋白酶:需钙蛋白酶I和需钙蛋白酶II。尽管需钙蛋白酶II是许多组织中的主导形式,但需钙蛋白酶I被认为是神经组织病理状况的主导形式。半胱氨酸蛋白酶的需钙蛋白酶类与很多疾病和失调有关,包括神经变性、中风、早老性痴呆、肌萎缩、运动神经元损害、急性中枢神经系统损伤、肌肉性营养障碍、骨吸收、血小板聚集、白内障和发炎。钙蛋白酶I与兴奋性氨基酸诱导神经中毒疾病有关,包括局部缺血、低血糖、杭廷顿氏舞蹈病和癫痫。溶酶体性半胱氨酸蛋白酶组织蛋白酶B与下列疾病有关:关节炎、发炎、心肌梗塞、肿瘤转移、肌肉营养不良。其它溶酶体性半胱氨酸蛋白酶包括组织蛋白酶C、H、L和S。白介素-1β转化酶(″ICE″)是一种半胱氨酸蛋白酶,其催化白介素-1β的形成。白介素-1β是一种免疫调节蛋白,其与下列疾病有关:发炎、糖尿病、脓毒性休克、类风湿性关节炎和早老性痴呆病。ICE还与神经元的编程性细胞死亡有关,其牵扯到各种神经变性疾病,包括帕金森氏病、局部缺血和肌萎缩性侧索硬化(ALS)。
半胱氨酸蛋白酶还由各种病原体产生。半胱氨酸蛋白酶梭菌蛋白酶由溶组织梭状芽胞杆菌产生。其它蛋白酶由Trpanosoma cruzi、疟疾寄生虫恶性疟原虫和P.vinckei疟原虫以及链球菌属产生。肝炎A病毒蛋白酶HAV C3是一种半胱氨酸蛋白酶,主要用于加工细小核糖核酸病毒结构蛋白质和酶。
与变性疾病有关的丝氨酸蛋白酶的实例包括凝血酶、人白细胞弹性蛋白酶、胰弹性蛋白酶、胃促胰酶和组织蛋白酶G。具体说,凝血酶在血凝固级联中产生,使血纤维蛋白分解成原纤维蛋白并且激活因子VIII;凝血酶与血栓静脉炎、血栓形成和气喘有关。人白细胞弹性蛋白酶涉及组织变性疾病,例如类风湿性关节炎、骨关节炎、动脉粥样硬化、支气管炎、胆囊纤维变性和肺气肿。胰弹性蛋白酶与胰腺炎有关。胃促胰酶是一种在血管紧张素合成中重要的酶,它与高血压、心肌梗塞和冠心病有关。组织蛋白酶G涉及异常结缔组织退化,特别是在肺中。
现有技术中描述了与本发明所公开的化合物结构不同的异羟肟酸酯类化合物,作为糖原磷酸化酶(国际专利申请WO 96/39385)和凝血酶(USP 5,563,127)的抑制剂。
由于半胱氨酸和丝氨酸蛋白酶与各种衰弱性疾病之间具有关系,因此抑制这些蛋白酶的化合物是有用的并且能够推进研究和临床药物。本发明涉及这些以及其它重要的目标。

式I化合物上存在的官能团可以含有保护基。例如,式1化合物的氨基酸侧链取代基可以被诸如苄氧羰基或叔丁氧羰基的保护基取代。保护基是已知的化学官能团,其可以供选择地附加在诸如羟基和羧基的官能团上并且除去。化合物中存在这些基团可使所说的官能团对化合物所处的化学反应条件呈惰性。本发明可以使用各种任何的保护基。一种这样的保护基是苄氧羰基(Cbz;Z)基团。本发明其它优选的保护基可参见Greene,T.W.和Wuts,P.G.M.″有机合成中的保护基″第2版,Wiley & Sons,1991。
这里所说的术语″酰氨基″习惯含义是式-C(=O)-NH-的基团。术语″烷基酰氨基″表示带有一个烷基取代基的酰氨基。术语″磺酰氨基″表示式-SO2-NH-的基团。通常来说,术语″烷基″或″芳基″当用作如″烷基磺酰氨基″、″烷基磺酰基″、″烷基硫氧基″或″烷硫基″的前缀时是指带有一个烷基取代基的磺酰氨基、磺酰基、硫氧基或硫基。
这里所述的式子中表示的一些构成基团可以被取代。这里所说的术语″取代″是指任何被称为″取代″部分上的可利用氢原子可以被所指定的基团替换。
在优选的实施方案中,本发明提供含有本发明化合物的用于抑制丝氨酸蛋白酶或半胱氨酸蛋白酶的组合物。在另外一些优选的实施方案中,本发明提供抑制丝氨酸蛋白酶或半胱氨酸蛋白酶的方法,该方法包括将选自丝氨酸蛋白酶和半胱氨酸蛋白酶的蛋白酶与抑制有效量的本发明化合物相接触。
本发明所公开的化合物对抑制半胱氨酸蛋白酶和丝氨酸蛋白酶是有效的。这里所说的术语″抑制″和″抑制性″是指对酶活性具有逆作用。抑制有效量是本发明化合物能够有效抑制半胱氨酸和/或丝氨酸蛋白酶的量。
半胱氨酸和丝氨酸蛋白酶抑制剂的药用可接受的盐也属于本发明的范围。这里所说的术语″药用可接受的盐″是指无机酸加成盐,如盐酸盐、硫酸盐和磷盐酸,或者是有机酸加成盐,如乙酸盐、马来酸盐、富马酸盐、酒石酸盐和柠檬酸盐。药用可接受的金属盐的例子是碱金属盐,如钠盐和钾盐;碱土金属盐,如镁盐和钙盐,铝盐和锌盐。药用可接受的铵盐的例子是铵盐和四甲基铵盐。药用可接受的有机胺加成盐的例子是与吗啉和哌啶的盐。药用可接受的氨基酸加成盐的例子是与赖氨酸、甘氨酸和苯丙氨酸的盐。

组合物可以方便地以单位剂量的形式给药并且可以通过药学领域公知的任何方法来制备,例如,在Remongton′s PharmaceuticalSciences(Mack Pub.Co.,Easton,PA,1980)中所述的方法。用于肠胃外给药的制剂中可以含有无菌水或盐水、聚亚烷基二醇如聚乙二醇、油和植物来源物、氢化萘等作为普通的赋形剂。具体说,可生物相容、生物降解的丙交酯聚合物、丙交酯/乙交酯共聚物或聚氧乙烯-聚氧丙烯共聚物对控制活性化合物的释放来说可以是有效的赋形剂。其它可能用于这些活性化合物的肠胃外传递体系包括乙烯-乙酸乙烯酯共聚物颗粒、渗透泵、可植入性注入体系和脂质体。用于吸入给药的制剂含有例如乳糖作为赋形剂,或者可以是含有如聚氧乙烯-9-月桂基醚、甘氨胆酸盐和脱氧胆酸盐的水溶液,或是以鼻滴剂形式给药的油状溶液,或者作为鼻内施用的凝胶。用于肠胃外给药的制剂中还可以含有便于口腔给药的甘氨胆酸盐、便于直肠给药的水杨酸盐或便于阴道给药的柠檬酸。用于经皮贴剂的制剂优选是亲脂性乳液。
本发明的材料可以作为药物中唯一的活性剂使用,也可以与其它活性剂如有助于疾病或病症中神经元存活或轴突再生的其它生长因子结合使用。
本发明所述化合物在治疗组合物中的浓度变化取决于很多因素,包括待用药物的剂量、所用化合物的化学特性(如疏水性)以及给药途径。通常来说,含有约0.1-10%w/v化合物的生理缓冲剂水溶液可以为肠胃外给药提供有效量的本发明化合物。典型的剂量范围为约1mg/kg-约1g/kg体重每天,优选剂量范围为约0.01mg/kg-100mg/kg体重每天。这种制剂一般来说可以提供抑制有效量的本发明化合物。然而,待用药物的优选剂量可能会根据诸如疾病或病症的类型和严重程度、特定患者的全身健康状况、所选化合物的相对生物有效性以及化合物赋形剂的配方及其施用途径这些不定因素而不同。
这里所说的术语″接触″是指直接或间接造成至少两个部分彼此物理性联系。因此接触包括物理作用,如将几个部分一起放入容器,或将几个部分施用给患者。因此,给有证据证明患有与所说蛋白酶异常和/或失常活性有关的疾病或病症的人施用本发明的化合物属于术语″接触″的定义的范围。
本发明还通过以下实施例的方式进一步说明,所说的实施例是为了阐明本发明。这些实施例不用来也不解释为限制本发明公开的范围。

为评价抑制活性,用100%无水DMSO制备各个化合物的试验用储备溶液(浓缩40倍),并且5μl各抑制剂制品的等分试样分到96-孔平板上的三个孔的每个孔中。将重组人类需钙蛋白酶稀释到化验用缓冲剂(即50mM Tris、50mM NaCl、1mM EDTA、1mM EGTA和5mM β-硫基乙醇,pH7.5,含有0.2mM Succ-Leu-Tyr-MNA)中,其中所说的重组人类需钙蛋白酶通过Meyer等的方法制备(Biochem.J.1996,314:511-519),并且将175μl等分试样分到含有各自抑制剂储备溶液的相同孔中,以及含有5μl DMSO但不含化合物的阳性对照中。为开始反应,将20μl存在于化验用缓冲剂中的50mM CaCl2添加到平板上的除三个孔以外的所有孔中,将所说的三个孔用作背景信号基准对照。每5分钟检测一次底物水解情况,检测总共30分钟。不含抑制剂的底物水解呈线性,最多15分钟。
需钙蛋白酶I活性的抑制率计算为存在抑制剂时底物水解率比不存在抑制剂时底物水解率的百分减少率。在底物水解呈线性的范围内进行抑制率和对照率之间的比较。根据在5至7种不同浓度试验化合物的存在下底物水解率的百分减少率确定抑制剂的IC50(产生50%抑制率的浓度)。将结果绘制成百分抑制率对log抑制剂浓度的曲线,并且通过使用GraphPad Prism程序(GraphPad软件公司,San Diego,CA),将数据带入下示的四参数逻辑等式中计算IC50。
y=d+[(a-d)/(1+(x/c)b)]
