在本申请中,术语0个或多个(例如,0个或1个以上、0个或1个、0个)亚甲基单元被“替代”通常指当所述结构包含1个或多个亚甲基单元时,所述一个或多个亚甲基单元可以不被替代,或被一个或多个不是亚甲基的基团(例如-NHC(O)-、-C(O)NH-、-C(O)-、-OC(O)-、-C(O)O-、-NH-、-O-、-S-、-SO-、-SO 2-、-PH-、-P(=O)H-、-NHSO 2-、-SO 2NH-、-C(=S)-、-C(=NH)-、-N=N-、-C=N-、-N=C-或-C(=N 2)-)所替代。
在本申请中,如本领域技术人员可知的,“烷基”、“烯基”、“环烷基”等之类的术语可以在名称前加一个标识表示在特定情况下基团中存在的原子数,例如,C 1-C 4烷基,C 3-C 7环烷氧基,C 1-C 4烷基羰基氨基等,“C”后所跟下标数字表示在基团中存在的碳原子数。例如,C 3烷基是指具有三个碳原子的烷基(例如,正丙基,异丙基);C 1-10中,基团的成员可具有落入1-10范围内的任何数目的碳原子。
基团中的一个或多个氢原子,例如为最多5个,例如为1~3个氢原子彼此独立地被相应数目的取代基取代。取代基仅处在它们的可能的化学位置,本领域技术人员能够在不付出过多努力的情况下确定(通过实验或理论)可能或不可能的取代。例如,具有游离氢的氨基或羟基与具有不饱和(如烯属)键的碳原子结合时可能是不稳定的。
在本申请中,术语“化合物”通常指具有两种或两种以上不同元素的物质。例如,本申请的化合物可以是有机化合物,例如本申请的化合物可以是分子量500以下的化合物,可以是分子量1000以下的化合物,也可以是分子量1000以上的化合物,也可以是10000以上、 100000以上的化合物。在本申请中,化合物还可以是指通过化学键相连的化合物,例如可以是一个或多个分子量1000以下的分子通过化学键与生物大分子相连的化合物,所述生物大分子可以是高聚糖、蛋白、核酸、多肽等。例如本申请的化合物可以包括蛋白质与一个或多个分子量1000以下的分子相连的化合物,可以是包括蛋白质与一个或多个分子量10000以下的分子相连的化合物,可以是包括蛋白质与一个或多个分子量100000以下的分子相连的化合物.
药物组合物可以是用于肌内和皮下给药的无菌注射水或油混悬液的形式。可按已知技术,用上述那些适宜的分散剂或湿润剂和悬浮剂配制该混悬液。无菌注射制剂也可以是在无毒肠胃外可接受的稀释剂或溶剂中制备的无菌注射溶液或混悬液,例如1,3-丁二醇中制备的溶液。此外,可方便地用无菌固定油作为溶剂或悬浮介质。例如,可使用包括合成甘油单或二酯在内的任何调和固定油。此外,脂肪酸例如油酸也可以制备注射剂。
在本申请中,本申请的化合物包含化合物的其互变异构体、内消旋体、外消旋体、对映异构体、和/或非对映异构体。在本申请中,术语“非对映异构体”通常是指具有两个或更多个手性中心并且其分子不是彼此的镜像的立体异构体。非对映异构体可以具有不同的物理性质,例如、熔点、沸点、波谱性质和反应性。在本申请中,术语“互变异构体”或“互变异构形式”可互换使用,通常是指可通过低能垒(low energy barrier)互相转化的不同能量的结构异构体。例如,质子互变异构体(protontautomer)(也称为质子移变互变异构体(prototropic tautomer))包括通过质子迁移进行的互相转化,诸如酮-烯醇异构化和亚胺-烯胺异构化。价键互变异构体(valence tautomer)包括通过一些成键电子的重组进行的互相转化。在本申请中,术语“内消旋体”通常是指分子内含有不对称性的原子,但具有对称因素而使分子内总旋光度为零。术语"外消旋体"或"外消旋混合物"是指由等摩尔量的两种对映异构体物质构成的组合物。
在本申请中,本申请的化合物的某些原子可能以一种以上的同位素形式出现。例如,氢可能以氕( 1H)、氘( 2H)和氚( 3H)的形式存在,碳可能以三种不同的同位素( 12C、 13C和 14C)自然存在。可并入本申请化合物中的同位素示例还包括但不限于 15N、 18O、 17O、 18F、 32P、 33P、 129I、 131I、 123I、 124I、 125I,或者类似的同位素。因此,相对于这些同位素的自然丰度,本申请的化合物可富集在一种或多种这些同位素中。如本领域技术人员所知,此类同位素富集化合物可用于多种用途。例如,用重同位素如氘( 2H)替代可能会提供某些治疗优势,这可以是由于更高的代谢稳定性。例如,氘( 2H)的自然丰度约为0.015%。因此,自然界中大约每6500个氢原子,就有一个氘原子。因此,本发明的含氘化合物在一个或多个位置(视情况而定)的氘丰度大于0.015%。除非另有指明,否则本申请所述的结构还可以包括仅在是 否存在一个或多个同位素富集原子方面存在差别的化合物。举例而言,除了氢原子被氘或氚所取代,或碳原子被碳13或碳14所取代之外,其余部分均与本申请结构一致的化合物均在本申请的范围之内。
在本申请中,“异构体”通常是指具有相同分子式的不同的化合物。“立体异构体”通常是指仅原子的空间排列方式不同的异构体。在本申请中,术语“异构体”包括任何以及所有几何异构体和立体异构体。例如,“异构体”包括几何双键顺式和反式异构体,也称为E–和Z–异构体;R–和S–对映异构体;非对映异构体、(d)–异构体和(l)–异构体、其外消旋混合物;及其落入本公开范围内的其他混合物。
在本申请中,“对映异构体”通常是指一对彼此的不可重叠的镜像的立体异构体。一对对映异构体的1:1混合物为“外消旋”混合物。适宜时,术语“(±)”用于表示外消旋混合物。“非对映异构体”是具有至少两个不对称原子,但不为彼此的镜像的立体异构体。绝对立体化学是根据Cahn-Ingold-Prelog R-S系统规定的。当化合物为纯对映异构体时,每个手性碳处的立体化学可以由R或S来指定。绝对构型未知的拆分的化合物可以根据其在钠D线的波长下使平面偏振光旋转的方向(右旋或左旋)来指定为(+)或(-)。本申请描述的某些化合物含有一个或多个不对称中心,因此可产生对映异构体、非对映异构体和其他可以根据绝对立体化学定义的立体异构形式,如(R)-或(S)-。本申请的化学实体、药物组合物和方法旨在包括所有这样的可能的异构体,包括外消旋混合物、光学纯形式和中间混合物。光学活性的(R)-和(S)-异构体可以使用手性合成子或手性试剂制备,或使用常规技术拆分。当本申请所述的化合物包含烯属双键或其他几何不对称中心时,并且除非另有说明,否则所述化合物旨在包括E和Z几何异构体二者。
在本申请中,术语“对映异构体纯度”通常是指特定对映异构体相对于另一种对映异构体的存在的相对量,以百分比表示。例如,如果可能具有(R)-或(S)-异构构型的化合物作为外消旋混合物存在,则就(R)-或(S)-异构体中的任一种而言,对映异构体纯度为约50%。如果该化合物的一种构形式优于另一种,例如,80%(S)-和20%(R)-,则该化合物就(S)-异构形式而言的对映体纯度为80%。化合物的对映异构体纯度可以通过本领域已知的多种方式测定,包括但不限于使用手性载体的色谱法,偏振光旋转的偏振测量,使用手性位移试剂(包括但不限于含有镧系元素的手性配合物或Pirkle醇)的核磁共振光谱法,或使用手性化合物如Mosher酸对化合物进行衍生化,然后进行色谱或核磁共振光谱。
在本申请中,术语“互变异构体”通常是指一种类型的异构体,其包括由氢原子的至少一种形式迁移及化合价的至少一种变化(例如,单键到双键、三键到双键或三键到单键,反之 亦然)产生的两种或多种可相互转化的化合物。“互变异构”包括质子移变或质子移动互变异构,其视为酸碱化学的一个子集。“质子移变互变异构”或“质子移动互变异构”涉及质子的迁移,伴随键级的变化。互变异构体的确切比例取决于多种因素,包括温度、溶剂和pH。当互变异构化可能存在(例如,在溶液中)时,可以达到互变异构体的化学平衡。互变异构(即,提供互变异构体对的反应)可以由酸或碱催化,或可以在没有外部试剂的作用或存在下发生。示例性的互变异构包括但不限于,酮-烯醇;酰胺-酰亚胺;内酰胺-内酰亚胺;烯胺-亚胺;和烯胺-(不同的)烯胺互变异构。酮-烯醇互变异构的具体的实例是戊烷-2,4-二酮与4-羟基戊-3-烯-2-酮互变异构体的相互转化。互变异构的另一个实例是酚-酮互变异构。酚-酮互变异构的具体实例为吡啶-4-醇和吡啶-4(1H)-酮互变异构体的相互转化。
在本申请中,术语“药物组合物”通常是指含有一种或多种本申请所述化合物或其生理学上/可药用的盐或前体药物与其他化学组分的混合物,以及其他组分例如生理学/可药用的载体和赋形剂。药物组合物可以是促进对生物体的给药,利于活性成分的吸收进而发挥生物活性。常规的药物组合物的制备可以见中国药典。
在本申请中,术语“药学上可接受的盐”或“可药用的盐”通常是指本申请化合物或配体-药物偶联物的盐,或本申请中所述的化合物的盐,这类盐用于哺乳动物体内时可以具有安全性和/或有效性,且可以具有应有的生物活性,本申请抗体-抗体药物偶联化合物可以与酸形成盐,药学上可接受的盐的非限制性实例包括:盐酸盐、氢溴酸盐、氢碘酸盐、硫酸盐、硫酸氢盐、柠檬酸盐、乙酸盐、琥珀酸盐、抗坏血酸盐、草酸盐、硝酸盐、梨酸盐、磷酸氢盐、磷酸二氢盐、水杨酸盐、柠檬酸氢盐、酒石酸盐、马来酸盐、富马酸盐、甲酸盐、苯甲酸盐、甲磺酸盐、乙磺酸盐、苯磺酸盐、对甲苯磺酸盐。

在本申请中,术语“接头”通常是指能够将蛋白质(例如,抗体、抗体片段(例如,抗原结合片段)或功能等效物)与糖皮质激素连接的任何化学部分。接头可能对切割敏感(“可切割接头”),从而促进糖皮质激素的释放。例如,在糖皮质激素和/或抗体保持活性的条件下, 此类可切割接头可能对酸诱导的切割、光诱导的切割、肽酶诱导的切割、酯酶诱导的切割和二硫键切割敏感。可替代地,接头可以基本上抗切割(“不可切割接头”)。
在本申请中,术语“药物抗体比”或“DAR”是指与A(即蛋白质,例如抗体或其抗原结合片段、抗TNF蛋白、抗TNF-α抗体或其片段、可溶性受体或可溶性TNF受体)连接的SM(即衍生自小分子糖皮质激素受体激动剂(例如,糖皮质激素)的基团)的数量。因此,在具有通式(SM-L-Q)n-A的免疫偶联物中,DAR由变量“n”限定。
当提及代表单独的免疫偶联物的具有式(SM-L-Q)n-A的化合物时,DAR通常是指与单独的A连接的SM的数量(例如,n是1至10的整数)。
当提及代表多种免疫偶联物的具有式(SM-L-Q)n-A的化合物时,DAR通常是指与A连接的SM的平均数量(例如,n是1至10的整数或分数)。因此,通过实例的方式,包含每个A含有3个SM的第一免疫偶联物和每个A含有4个SM的第二免疫偶联物的具有式(SM-L-Q)n-A的化合物的DAR(即,“n”)为3.5。
在本申请中,不可切割接头通常是能够以稳定的共价方式将糖皮质激素与抗体连接的任何化学部分,并且在上文针对可切割接头列出的类别下不会脱落。因此,不可切割接头基本上抗酸诱导的切割、光诱导的切割、肽酶诱导的切割、酯酶诱导的切割和二硫键切割。此外,不可切割是指在糖皮质激素和/或抗体不丧失其活性的条件下,接头中或与接头相邻的化学键承受由酸、光不稳定切割剂、肽酶、酯酶或者切割二硫键的化学或生理化合物诱导的切割的能力。
一些可切割接头被肽酶切割(“肽酶可切割接头”)。只有某些肽易于在细胞内部或外部切割,参见例如Trout等人,Proc.Natl.Acad.Sci.USA[美国国家科学院院刊],626-629(1982)和Umemoto等人Int.J.Cancer[国际癌症杂志],677-684(1989)。此外,肽由α-氨基酸单元和肽键组成,肽键在化学上是一个氨基酸的羧酸和第二个氨基酸的氨基之间的酰胺键。其他酰胺键(如赖氨酸的羧酸和α-氨基酸基团之间的键)应理解为不是肽键并且被认为是不可切割。
一些接头被酯酶切割(“酯酶可切割接头”)。只有某些酯可以被存在于细胞内部或外部的酯酶切割。酯通过羧酸和醇的缩合形成。简单酯是用简单醇(如脂族醇)和小环状醇和小芳香醇产生的酯。
在一些实施例中,可切割接头组分可以包含含有1至10个氨基酸残基的肽。在这些实施例中,肽允许蛋白酶切割接头,从而在暴露于细胞内蛋白酶(如溶酶体酶)时促进糖皮质激素的释放(Doronina等人(2003)Nat.Biotechnol.[自然生物技术]21:778-784)。示例性肽包括但 不限于二肽、三肽、四肽和五肽。示例性二肽包括但不限于丙氨酸-丙氨酸(ala-ala);缬氨酸-瓜氨酸(vc或val-cit);丙氨酸-苯丙氨酸(af或ala-phe);苯丙氨酸-赖氨酸(fk或phe-lys);苯丙氨酸-高赖氨酸(phe-homolys);和N-甲基-缬氨酸-瓜氨酸(Me-val-cit)。示例性三肽包括但不限于甘氨酸-缬氨酸-瓜氨酸(glv-val-cit)和甘氨酸-甘氨酸-甘氨酸(gly-gly-gly)。

氨基酸还可以包括D-形式的天然氨基酸和非天然氨基酸。“D-”表示具有“D”(右旋)构型的氨基酸,与天然存在的(“L-”)氨基酸中的构型相反。天然氨基酸和非天然氨基酸可以是可商购的(西格玛化工有限公司(Sigma Chemical Co.)、先进化学技术公司(AdvancedChemtech))或可以使用本领域已知的方法合成。

在本申请中,术语“可变区”或“可变结构域”通常是指参与抗体与抗原的结合的抗体重链或轻链的结构域。在本申请中,术语“可变”通常是指,抗体的可变结构域的序列的某些部分变化强烈,形成各种特定抗体对其特定抗原的结合和特异性。变异性并非均匀地分布在抗体的整个可变区中。它集中在轻链可变区和重链可变区中的三个区段,被称为互补决定区(CDR)或高变区(HVR),分别为LCDR1、LCDR2、LCDR3、HCDR1、HCDR2和HCDR3。可变域中更高度保守的部分被称为框架区(FR)。天然重链和轻链的可变结构域各自包含四个FR区(H-FR1,H-FR2,H-FR3,H-FR4,L-FR1,L-FR2,L-FR3,L-FR4),大部分采用β-折叠构型,通过三个CDR结构环区连接。每条链中的CDR通过FR区紧密靠近在一起,并与来自另一条链的CDR一起形成抗体的抗原结合位点。
在本领域中,可以通过多种方法来编码抗体的可变区或划分抗体的CDR,例如基于序列可变性的Kabat编号方案和定义规则(参见,Kabat等人,免疫学的蛋白质序列,第五版,美国国立卫生研究院,贝塞斯达,马里兰州(1991)),基于结构环区域位置的Chothia编号方案和定义规则(参见,A1-Lazikani等人,JMol Biol 273:927-48,1997),efranc等人的基于种系V基因的氨基酸序列比对的IMGT编号方案和定义规则,还有Honneger’s编号方案(AHo’s),Martin编号方案,Gelfand编号方案等,可参见Mathieu Dondelinger等人,Understanding the Significance and Implications of Antibody Numbering and Antigen-Binding Surface/Residue Definition,Front.Immunol.,16 October 2018.
在本申请中,术语“百分比(%)序列同一性”通常是指两个或更多个经比对的氨基酸序列与组成这些氨基酸序列的总长度的氨基酸残基数相比而言一致的氨基酸的匹配(“命中”)数。换言之,使用比对,对于两个或更多个序列,当将这些序列针对最大对应(如使用本领域已知的序列比较算法测量的)进行比较和比对时,或者当手动比对和视觉检查时,可以确定相同的氨基酸残基的百分比(例如70%、75%、80%、85%、90%、95%、96%、97%、98%或99%序列同一性)。因此,进行比较以确定序列一致性的序列可以通过一个或多个氨基酸取代、添加或缺失来区分。用于比对蛋白序列的适合程序是本领域技术人员已知的。蛋白序列的百分比序列一致性可以例如用程序如CLUSTALW、Clustal Omega、FASTA或BLAST来确定,例如使用NCBI BLAST算法(AltschulSF等人(1997),Nucleic Acids Res.[核酸研究]25:3389-3402)。
在本申请中,术语“抗体类似物”通常以最广意义使用并且特别地涵盖以单特异性特异地结合靶分子并且结构上与天然抗体不同的分子。例如,在描述抗PD-1抗体或抗PD-L1抗体的上下文中,术语“抗体类似物”是指包含与氨基酸序列的部分具有大体上的同一性的区段并且具有至少一个下列性质的抗体:(1)在适当的结合条件下特异性结合PD-1或PD-L1,(2)抑制PD-1或PD-L1的至少一个生物活性的能力。通常,抗体类似物包含相对于天然序列的保守氨基酸置换(或插入或缺失)。类似物通常为至少20或25个氨基酸长,至少50、60、70、80、90、100、150或200个氨基酸长或更长,并且通常可与抗体的全长重链或轻链一样长。一些例子包括与种系氨基酸序列相比具有1、2、3、4、5、6、7、8、9、10、11、12、13、14、15、16或17个置换的抗体类似物。
