“前体药物”是指需要在体内进行转化才能释放出活性药物的药物分子的衍生物。前体药物在转化为母体药物之前,通常(但不一定)在药理上无活性。前体药物可以通过将前体部分(promoiety)通常经由官能基团键合至药物而获得。例如,对于式(1)化合物,酰氧基烷基前体部分(promoiety)通过氯胺酮的酰胺基团与药物氯胺酮键合。式(1)化合物是氯胺酮的前体药物,可在患者身体内被代谢以释放氯胺酮。
“前体部分(Promoiety)”是指通过特定使用条件下可裂解的键与药物键合的基团,通常与药物的官能团键合。药物和前体部分(promoiety)之间的键可以用酶或非酶的方式裂解。在使用条件下,例如在向患者施用施用后,药物和前体部分(promoiety)之间的键可以被裂解以释放母体药物。前体部分(promoiety)的裂解可以自发地进行,例如经由水解反应,或者前体部分(promoiety)可以被另一种动因(agent),例如通过酶、通过光、通过酸、或通过改变或暴露于物理或环境参数(例如温度、pH值等的变化)被催化或诱导。该动因对于使用条件可以是内源性的,例如在被施用前体药物的患者的体循环中存在的酶或胃的酸性条件,或者该动因可以以外源方式提供。本公开内容提供的酰氧基烷基衍生物是氯胺酮的前体药物。酰氧基烷基前体部分(promoiety)具有以下结构:例如,对于式(1)化合物,酰氧基前体部分(promoiety)具有以下结构:
其中R1和R2如针对式(1)所定义。酰氧基烷基前体部分(promoiety)在体内被裂解以释放氯胺酮进入体循环。
“溶剂化物”是指化合物与一个或多个化学计量或非化学计量的溶剂分子的分子复合物。这样的溶剂分子是通常用于制药领域中已知对患者无害的那些溶剂分子,如水或乙醇。化合物或化合物的部分(moiety)与溶剂的分子复合物可以被非共价分子内部力所稳定,例如静电力、范德华力或氢键。术语“水合物”是指其中一个或多个溶剂分子是水的溶剂化物。制备溶剂化物的方法包括,例如,在含有溶剂的气氛中存储、包含溶剂的剂型或常规药物加工步骤,例如结晶(即从溶剂或混合溶剂中结晶)蒸汽扩散。在某些情况下,也可以由在暴露于溶剂或暴露于溶剂中的混悬物质后形成的其它结晶溶剂化物或水合物形成溶剂化物。溶剂化物可以以多于一种的形式结晶,从而产生溶剂化物的多晶形。
“取代(Substituted)”是指基团中一个或多个氢原子独立地被相同或不同的取代基替换。每个取代基可以独立地选自氘、卤素、-OH、-CN、-CF3、-OCF3、=O、-NO2、C1-6烷氧基、C1-6烷基、-COOR、-NR2和-CONR2;其中R可以各自独立地选自氢和C1-6烷基。每个取代基可以独立地选自氘、卤素、-NH2、-OH、C1-3烷氧基、和C1-3烷基、三氟甲氧基和三氟甲基。每个取代基可以独立地选自氘、-OH、甲基、乙基、三氟甲基、甲氧基、乙氧基和三氟甲氧基。每个取代基可以选自氘、C1-3烷基、=O、C1-3烷基、C1-3烷氧基和苯基。每个取代基可以选自氘、-OH、-NH2、C1-3烷基和C1-3烷氧基。
“缓释(Sustained release)”是指相对于通过相同施用途径施用相同化合物的速释制剂,在延长的时间段过程中以在患者体循环中有效实现化合物或其活性代谢产物的治疗或预防浓度的速率从药物组合物的剂型释放化合物。在一些实施方案中,化合物的释放在至少约4小时的时间段过程中发生,例如至少约8小时、至少约12小时、至少约16小时、至少约20小时,并且在一些实施方案中,至少约24小时。
“治疗”(“Treating”或“treatment”)疾病是指阻止或缓解疾病或者疾病或障碍的至少一种临床症状、降低患有疾病或疾病的至少一种临床症状的风险、减少疾病或疾病的至少一种临床症状的发展、或降低疾病或疾病的至少一种临床症状恶化的风险。“治疗”还指以物理方式(例如稳定可辨别的症状)、以生理方式(例如稳定人体生理参数)或以两者来抑制疾病,还指抑制对于患者可能辨别或者可能无法辨别的至少一种人体生理参数或表征。“治疗”还指在可能接触或易患疾病或障碍的患者中延迟疾病的发作或延迟其至少一种或多种症状的发作,即使该患者尚未经历或显示该疾病的症状。
“治疗有效量(therapeutically effective amount)”是指当被施用于患者用于治疗疾病或疾病的至少一种临床症状时足以影响该疾病或其症状的治疗的化合物的量。“治疗有效量”可以例如因化合物;疾病和/或疾病的症状;疾病的严重程度和/或疾病或障碍的症状;接受治疗的患者的年龄、体重和/或健康状况以及开处方医生的判断而有所不同。在任何给定的情况下,合适的量可以由本领域技术人员确定或能够通过常规实验确定。
“治疗有效剂量(therapeutically effective dose)”是指向患者提供有效治疗疾病或障碍的剂量。治疗有效剂量可以因化合物而异,还可以因患者而异,并且可能取决于例如患者的状况和递送途径的因素。治疗有效剂量可以根据本领域技术人员已知的常规药理方法确定。
“媒介物”(Vehicle)是指与化合物一起施用于患者的稀释剂、赋形剂或载体。媒介物可以是药学上可接受的媒介物。药学上可接受的媒介物是本领域已知的。
现对某些化合物和方法进行说明。所公开的实施方案并不旨在对权利要求有所限制。与此相反,权利要求书旨在涵盖所有替代、修改和等同形式。

本公开内容提供的药物组合物包含式(1)化合物或其药学上可接受的盐。本公开内容提供的药物组合物包含式(1)化合物或其药学上可接受的盐和至少一种药学上可接受的赋形剂。药学上可接受的赋形剂是已知的。
可以将本公开内容提供的药物组合物配制为用于口服施用。所述组合物可以是例如溶液剂、混悬剂、片剂或锭剂的形式。
口服剂型可以包含治疗有效量的式(1)化合物。
口服剂型可以包括缓释口服剂型。
口服施用至患者后,式(1)化合物被胃肠道吸收到体循环中,在体循环中前体部分(promoiety)被裂解以形成氯胺酮的体循环。
可以将式(1)化合物纳入药物组合物而被口服施用。口服施用该药物组合物导致式(1)化合物在整个或部分胃肠道中被吸收并进入体循环。
本公开内容提供的口服剂型可以是控释剂型。受控递送技术可以提高药物在特定区域或胃肠道区域中的吸收。
受控药物递送系统可以设计成以如下方式递送药物:只要该系统以特定的速度持续递送药物,就可以将药物水平维持在治疗有效范围内,并在一段时间内保持有效和安全的血液水平。与立即释放剂型观察到的波动相比,受控药物递送可以在一段时间内产生基本恒定的药物的血液水平。对于某些药物,在整个治疗过程中保持恒定的血液和组织浓度是最理想的治疗方式。立即释放药物可能会导致血液水平达到引发所需响应所需水平的峰值,这可能会浪费药物并可能导致或加剧毒副作用。受控药物递送可以导致最佳治疗,不仅可以减少给药频率,还可以减少副作用的严重程度。控释剂型的示例包括溶解控制系统、扩散控制系统、离子交换树脂、渗透控制系统、可腐蚀基质系统、pH独立剂型和胃滞留系统。
无论所使用的控释口服剂型的具体类型,式(1)化合物可以在足够长的时间段内从口服施用的剂型中释放出来,以提供式(1)化合物在患者的血浆和/或血液中的延长的治疗浓度。口服施用后,包含式(1)化合物的剂型可以在向患者口服施用该剂型后的至少约4小时、至少约8小时、至少约12小时、至少约16小时、并且在某些实施方案中至少约20小时的持续时间段在患者的血浆和/或血液中提供相应药物的治疗有效浓度。维持药物的治疗有效浓度的持续时间段可以相同或不同。维持药物的治疗有效血浆浓度的持续时间段可以在口服施用后不久或在一定时间间隔后开始。
口服施用式(1)化合物且被吸收进入体循环后,包含式(1)化合物的剂型可以在向患者口服施用该剂型后的至少约4小时、至少约8小时、至少约12小时、至少约16小时、至少约20小时或至少约24小时的时间段在患者的血浆和/或血液中提供氯胺酮的治疗或预防浓度。
无论所使用的缓释口服剂型的具体形式,式(1)化合物可以在足够长的时间段内从剂型例如口服施用剂型中释放出来,以提供式(1)化合物在患者的血液中延长的治疗浓度,从而允许每天仅一次或两次施用该剂型。
本公开内容提供的药物组合物可以以适于在口服施用后提供式(1)化合物的持续释放的剂型来实施。缓释口服剂型可以用于在延长的时间段内释放药物,并且有效用于在需要将药物或药物剂型递送到下消化道时。缓释口服剂型包括使药物的治疗浓度在生物液体(如血浆、血液、脑脊液)或者在组织或器官中维持延长的时间段的任何口服剂型。缓释口服剂型包括扩散控制系统如储备装置和基质装置、溶解控制系统、渗透系统和侵蚀控制系统。缓释口服剂型及制备其的方法是本领域众所周知的。
本公开内容提供的缓释口服剂型可以从该剂型中释放式(1)化合物以促进式(1)化合物从胃肠道的适当区域(例如在小肠中或在结肠中)被吸收的能力。缓释口服剂型可以在至少约4小时、至少约8小时、至少约12小时、至少约16小时、至少约20小时、并且在某些实施方案中至少约24小时的时间段内从该剂型中释放出式(1)化合物。缓释口服剂型可以以对应于在约0至约4小时内约0wt%至约20wt%、在约0至约8小时内约20wt%至约50wt%、在约0至约14小时内约55wt%至约85wt%、并且在约0至约24小时内约80wt%至约100wt%的递送方式从该剂型中释放出式(1)化合物,其中wt%是指该剂型中化合物总重量的百分比。缓释口服剂型可以以对应于在约0至约4小时内约0wt%至约20wt%、在约0至约8小时内约20wt%至约50wt%、在约0至约14小时内约55wt%至约85wt%、并且在约0至约20小时内约80wt%至约100wt%的递送方式从该剂型中释放出式(1)化合物。缓释口服剂型可以以对应于在约0至约2小时内约0wt%至约20wt%、在约0至约4小时内约20wt%至约50wt%、在约0至约7小时内约55wt%至约85wt%、并且在约0至约8小时内约80wt%至约100wt%的递送方式从该剂型中释放式(1)出化合物。
包含式(1)化合物的缓释口服剂型在口服施用至患者后可以随时间推移在该患者的血浆、血液、脑脊液或组织中提供一定浓度的相应药物。药物的浓度曲线可以显示出与相应的式(1)化合物的剂量成比例的AUC。
本公开内容提供的用于特定药物组合物的合适的口服剂型至少部分地取决于式(1)化合物的胃肠道吸收特性、式(1)化合物在胃肠道中的稳定性、式(1)化合物的药代动力学和预期的治疗特性。对于特定的式(1)化合物,可以选择合适的控释或缓释口服剂型。例如,胃内滞留口服剂型可能适合用于主要从上消化道被吸收的化合物,而缓释口服剂型可能适合用于主要从下消化道被吸收的化合物。某些化合物主要从小肠被吸收。通常,化合物在约3至5小时内穿越小肠的长度。对于不易被小肠吸收或不易溶解的化合物,活性药剂在小肠中吸收的时间窗可能太短而无法提供所需的治疗效果。
可以选择式(1)化合物的剂量和合适的给药间隔以在患者的血液中维持式(1)化合物的持续治疗有效浓度,并且在某些实施方案中,不超过最小的不良反应浓度。
患者的血液或血浆中式(1)化合物的治疗有效浓度可以小于引起不可接受的副作用(包括对稳态的不利影响)的量。患者的血液或血浆中式(1)化合物的治疗有效浓度可以是足以恢复和/或维持患者中稳态的量。例如,在施用治疗有效剂量的式(1)化合物后,可以将氯胺酮的治疗有效量维持大于1小时、大于2小时、大于3小时、大于4小时、大于5小时、大于6小时、大于7小时或大于8小时。例如,在施用治疗有效剂量的式(1)化合物后,可以将氯胺酮的治疗有效量维持例如1小时至10小时、2小时至8小时、2小时6或2小时4小时。
在某些实施方案中,施用剂量小于毒性剂量。可以通过在细胞培养物或实验动物中的标准药学程序,例如通过测定LD50(使群体的50%致死的剂量)或LD100(使群体的100%致死的剂量),来确定本文所述的组合物的毒性。毒性和治疗效果之间的剂量比是治疗指数。在某些实施方案中,氯胺酮衍生物可以表现出高治疗指数。从这些细胞培养测定法和动物研究中获得的数据可用于制定对于人类使用无毒性的剂量范围。本公开内容提供的氯胺酮衍生物的剂量可以在例如血液、血浆或中枢神经系统中的循环浓度范围内,其包括有效剂量并且具有很小毒性或没有毒性。取决于所使用的剂型和使用的施用途径,剂量在此范围内可以有所不同。在某些实施方案中,可以施用递增剂量。

犬体内药代动力学研究:将3只雄性比格犬单独圈养。口服施用组中的犬在处理前禁食过夜,但可以自由获取水。静脉内(IV)施用组的犬可以自由获取食物和水。对于S-氯胺酮盐酸盐,通过静脉内(IV)施用向每只犬施用3.75μmol/kg的单个剂量。用于S-氯胺酮盐酸盐的媒介物是盐水。对于其它测试化合物,通过口服管饲法向每只犬施用单剂量的每种测试化合物(n=3/组)。用于给药测试化合物的媒介物取决于测试化合物的性质。在对IV和PO组中的每只犬施用药物后,在特定的时间点(给药前、给药后10min、30min、1h、2h、3h、4h、5h、6h、8h)采集血液样本。为防止化合物降解,应立即以1:3(v/v)的比例将抽取的血液样本与乙腈(含0.1%甲酸)混合。在进行生物分析之前,将脱蛋白的样本暂时保持在冰中,然后将其保存在-70℃。通过LC-MS/MS测定血液中分析物的浓度。使用PhoenixTM 软件计算各种药代动力学参数。为了对测试化合物在循环系统中的生物转化效率进行定量,计算了经PO施用后S-氯胺酮的生物利用度。
猴体内药代动力学研究:在这项研究中,使用了来自国防医学中心(NDMC)实验动物中心(LAC)群体的三只食蟹猴(两只雄性,一只雌性)(食蟹猴Macaca fascicularis)。猴的平均年龄为6岁,平均体重为6.6kg(6kg至7kg)。在静脉内施用S-氯胺酮和口服施用S-氯胺酮和化合物3之后,评估了S-氯胺酮和化合物3的药代动力学。每次处理之间进行至少7天的洗脱。在体内实验的当天,通过肌肉内注射(5mg/kg)和右旋美托咪啶(10mcg/kg)使猴镇静。对于静脉内施用,以3.2μmol/kg的剂量通过头静脉作为推注缓慢施用S-氯胺酮溶液。施用的剂量体积为0.5mL/kg。对于口服施用,通过口服管饲法以6.4μmol/kg施用S-氯胺酮或化合物3。施用的剂量体积为1mL/kg。静脉内处理组中的猴自由获取实验室食物,口服处理组中的猴在处理前禁食过夜,并在施用测试化合物后2至3小时喂食。在研究期期间,以自由获取的方式提供饮用水。通过隐静脉从猴收集系列血液样本(0.35mL/每只)。将收集的血液样品放入含有作为抗凝剂的肝素的试管中。将收集的血液样本放入含有肝素作为抗凝剂的试管中。在给药前,给药后0.083、0.5、1、1.5、2、3、4、6、8和24hr收集IV组的血液样本。对于PO组,在给药前、给药后0.5、1、1.5、2、3、4、5、6、8和24hr采集血液样本。为了防止化合物降解,从猴抽取100μL血液样本后,应立即以1:3(v/v)的比例与300μL乙腈(含0.1%甲酸)混合。在进行生物分析之前,将脱蛋白的样本暂时保持在冰中,然后将其保存在-70℃。通过LC-MS/MS测定血液中分析物的浓度。
生物分析:通过LC-MS/MS系统以多反应监测(MRM)模式监测母体化合物的消失和氯胺酮的形成。使用二元溶剂系统以0.8mL/min的恒定流速进行流动相:溶剂A,含0.1%甲酸的去离子水,和溶剂B,含0.1%甲酸的甲醇。采集MRM数据,并使用1.5.2版本的QuantWizard软件(ABI的Analyst Software)对色谱图进行积分。使用加权(1/x或1/x2)线性回归由标准品生成校准曲线并计算样本浓度。
药代动力学数据分析:使用PhoenixTM WinNonlin程序6.3版(Phoenix2012,Pharsight Corporation,Mountain View,CA)估算每个受试者的药代动力学参数。进行非分区分析以生成参数估算。在可能的情况下,通过血液浓度-时间数据的对数线性图的最终消除阶段进行线性回归来获得最终消除速率常数(λ)。λ接受的标准是来自最终消除阶段的至少三个时间点的回归且r2≥0.85。如果不能满足标准,则将半衰期定义为未确定(ND)。标称时间用于t1/2和AUC计算。根据以下公式计算表观血液最终消除半衰期:t1/2=ln(2)/λ。通过目视检查实验数据获得观察到的最大血液浓度(Cmax)和达到最大血液浓度的时间(Tmax)。通过线性梯形法确定从时间0到最后可测量浓度的氯胺酮血液浓度-时间曲线下的面积(AUC(0-最后))。通过AUC(0-最后)+C最后/λ确定从时间0到无穷(∞)的血液浓度-时间曲线下的面积(AUC(0-∞)),其中C最后是对应于最后可测量浓度的时间点(T最后)的浓度。
平均停留时间(MRT)由(AUMC(0-∞)/AUC(0-∞))的比值获得,其中AUMC(0-∞)是一阶矩曲线下的面积,其等于:
根据以下公式计算表观血液总清除率(CL)和稳态分布体积(Vss):CL=剂量IV/AUC(0-∞)和Vss=MRT×CL。
