代谢
大约60%的吸收剂量通过肝酯酶介导的去酯化作用广泛水解为依那普利拉。在人体内,未观察到超出生物激活至依那普利拉的代谢。
About 60% of the absorbed dose is extensively hydrolyzed to enalaprilat via de-esterification mediated by hepatic esterases. In humans, metabolism beyond bioactivation to enalaprilat is not observed.

代谢
大约60%的依那普利剂量被广泛水解为依那普利拉,主要在肝脏通过酯酶进行。大约20%在首次通过肝脏时似乎被水解;这种水解在人类血浆中似乎并不发生。依那普利拉是一种比依那普利更强的血管紧张素转换酶抑制剂。在人类、大鼠或狗中没有发现依那普利其他代谢物的证据。然而,在恒河猴的尿液中发现了依那普利拉的脱丙基代谢物,占依那普利马来酸盐口服剂量的13%。在严重肝功能损害的患者中,依那普利水解为依那普利拉可能会延迟和/或受损,但药物的药效动力学效果似乎并没有显著改变。
About 60% of an absorbed dose of enalapril is extensively hydrolyzed to enalaprilat, principally in the liver via esterases. About 20% appears to be hydrolyzed on first pass through the liver; this hydrolysis does not appear to occur in plasma in humans. Enalaprilat is a more potent angiotensin converting enzyme inhibitor than enalapril. There is no evidence of other metabolites of enalapril in humans, rats, or dogs. However, a despropyl metabolite of enalaprilat was identified in urine in rhesus monkeys, accounting for 13% of an oral dose of enalapril maleate. Hydrolysis of enalapril to enalaprilat may be delayed and/or impaired in patients with severe hepatic impairment, but the pharmacodynamic effects of the drug do not appear to be significantly altered.

毒理性
  • 毒性总结
识别和使用:依那普利是血管紧张素转换酶抑制剂和抗高血压药。人类研究:依那普利过量会产生主要延伸药物作为血管紧张素转换酶抑制剂药理效果的影响。在2名患者中,急性摄入300-440毫克依那普利马来酸盐后10-15小时内,血浆血管紧张素酶活性被完全抑制。依那普利过量的最可能表现是低血压,这可能是深度的,也可能伴随昏迷。急性过量后,低血压效果的开始和持续时间可能会延长。还可能发生肾功能不全,包括急性肾衰竭、高钾血症和低钠血症。在怀孕的第二和第三个月使用作用于肾素-血管紧张素系统的药物会降低胎儿肾功能,并增加胎儿和新生儿发病率和死亡。导致的少羊水可以与胎儿肺发育不良和骨骼畸形有关。潜在的新生儿不良反应包括头骨发育不良、无尿、低血压、肾衰竭和死亡。当发现怀孕时,尽快停止使用依那普利马来酸盐片。动物研究:当依那普利以高达90毫克/千克/天的剂量给予雄性和雌性大鼠106周,或以高达90和180毫克/千克/天的剂量分别给予雄性和雌性小鼠94周时,没有肿瘤发生的证据。在使用高达90毫克/千克/天依那普利的雄性和雌性大鼠的生殖性能上没有不良影响。依那普利马来酸盐或活性二酸在Ames微生物突变试验中无论有无代谢激活均不具有突变性。依那普利在以下遗传毒性研究中也为阴性:rec-分析,以大肠杆菌为反向突变分析,以培养的哺乳动物细胞为姐妹染色单体交换,以小鼠为微核试验,以及在体内使用小鼠骨髓的细胞遗传学研究。
IDENTIFICATION AND USE: Enalapril is angiotensin-converting enzyme inhibitor and antihypertensive agent. HUMAN STUDIES: Overdosage of enalapril produces effects that are mainly extensions of the drug's pharmacologic effects as an angiotension converting enzyme inhibitor. Plasma angiotension enzyme activity was completely suppressed within 10-15 hr after acute ingestion of 300-440 mg of enalapril maleate in 2 patients. The most likely manifestation of enalapril overdosage is hypotension, which may be profound and also maybe accompanied by stupor. Onset and duration of the hypotensive effect may be prolonged following acute overdosage. Renal dysfunction, including acute renal failure, hyperkalemia, and hyponatremia may also occur. Use of drugs that act on the renin-angiotensin system during the second and third trimesters of pregnancy reduces fetal renal function and increases fetal and neonatal morbidity and death. Resulting oligohydramnios can be associated with fetal lung hypoplasia and skeletal deformations. Potential neonatal adverse effects include skull hypoplasia, anuria, hypotension, renal failure, and death. When pregnancy is detected, discontinue enalapril maleate tablets as soon as possible. ANIMAL STUDIES: There was no evidence of a tumorigenic effect when enalapril was administered for 106 weeks to male and female rats at doses up to 90 mg/kg/day or for 94 weeks to male and female mice at doses up to 90 and 180 mg/kg/day, respectively. There were no adverse effects on reproductive performance of male and female rats treated with up to 90 mg/kg/day of enalapril. Neither enalapril maleate nor the active diacid was mutagenic in the Ames microbial mutagen test with or without metabolic activation. Enalapril was also negative in the following genotoxicity studies: rec-assay, reverse mutation assay with Escherichia coli, sister chromatid exchange with cultured mammalian cells, and the micronucleus test with mice, as well as in an in vivo cytogenic study using mouse bone marrow.

吸收、分配和排泄
  • 吸收
口服给药后,依那普利在1小时内达到血浆峰浓度(Cmax),而依那普利拉的Cmax出现在给药后三到四小时。稳态在第四天剂量时达到,重复给药没有积累。然而,在肌酐清除率小于30 mL/min的患者中可能会出现依那普利拉的积累。食物摄入对药物吸收的影响最小。口服给药后,大约60%的依那普利被吸收。以静脉注射依那普利拉作为参照标准时,依那普利的生物利用度平均约为40%。
Following oral administration, the peak plasma concentrations (Cmax) of enalapril is achieved within 1 hour post dosing while the Cmax of enalaprilat occurs at three to four hours post dosing. The steady-state is achieved by the fourth daily dose and there is no accumulation with repeated dosing. However, accumulation of enalaprilat may occur in patients with creatinine clearance less than 30 mL/min. Food intake is reported to have a minimal effect on drug absorption. Following oral administration, about 60% of enalapril was absorbed. Bioavailability of enalapril averaged about 40% when intravenous enalaprilat was used as a reference standard.

吸收、分配和排泄
  • 消除途径
恩纳普利主要通过肾脏排泄,大约94%的总剂量以恩纳普利酸或未改变的母体化合物的形式通过尿液或粪便排出。大约61%和33%的总剂量可以在尿液和粪便中分别回收。在尿液中,大约40%的回收剂量以恩纳普利酸的形式存在。
Enalapril is mainly eliminated through renal excretion, where approximately 94% of the total dose is excreted via urine or feces as either enalaprilat or unchanged parent compound. About 61% and 33% of the total dose can be recovered in the urine and feces, respectively. In the urine, about 40% of the recovered dose is in the form of enalaprilat.

吸收、分配和排泄
  • 分布容积
分布容积尚未确定。尽管在治疗剂量下,穿越血脑屏障的情况尚未得到证实,但试验表明,enalaprilat可渗透大多数组织,尤其是肾脏和血管组织。在犬类研究中,enalapril和enalaprilat穿越血脑屏障的能力较差。极小量的药物会渗透进乳汁,但会发生显著的胎儿转移。该药物在大鼠和仓鼠中穿越胎盘屏障。
The volume of distribution of enalapril has not been established. Enalaprilat is shown to penetrate into most tissuesm, in particular the kidneys and vascular tissuem, although penetration of the blood-brain barrier has not been demonstrated after administration at therapeutic doses. In dog studies, enalapril and enalaprilat cross the blood-brain barrier poorly. Minimal penetration occurs into breast milk but significant fetal transfer occurs. The drug crosses the placental barrier in rats and hamsters.

在健康男性志愿者口服给药后,肾清除率大约为158 ± 47 mL/min。据报道,恩纳普利和恩纳普利拉在给药后4小时内在血浆中检测不到。

静脉注射依那普利0.50 mg/kg、口服安慰剂以及口服依那普利三种不同剂量(0.50、1.00和2.00 mg/kg)的药代动力学和药效学在7匹健康马匹中进行了分析。对依那普利及其活性代谢物依那普利拉的血清浓度进行了药代动力学分析。测定了血管紧张素转换酶(ACE)活性、血清尿素氮(SUN)、肌酐和电解质,并监测了血压以进行药效学分析。静脉注射依那普利后,依那普利和依那普利拉的消除半衰期分别为0.67小时和2.76小时。口服给药后,所有马匹的依那普利浓度均低于定量限(10 ng/mL),7匹马中有4匹马匹的依那普利拉浓度低于定量限。从基线开始的平均最大ACE抑制率分别为静脉注射依那普利0.50 mg/kg的88.38%,安慰剂的3.24%,口服依那普利0.50 mg/kg的21.69%,1.00 mg/kg的26.11%,和2.00 mg/kg的30.19%。在实验期间,血压、SUN、肌酐和电解质保持不变。
Pharmacokinetic and pharmacodynamic of IV enalapril at 0.50 mg/kg, PO placebo and PO enalapril at three different doses (0.50, 1.00 and 2.00 mg/kg) were analyzed in 7 healthy horses. Serum concentrations of enalapril and enalaprilat were determined for pharmacokinetic analysis. Angiotensin-converting enzyme (ACE) activity, serum ureic nitrogen (SUN), creatinine and electrolytes were measured, and blood pressure was monitored for pharmacodynamic analysis. The elimination half-lives of enalapril and enalaprilat were 0.67 and 2.76 hr respectively after IV enalapril. Enalapril concentrations after PO administrations were below the limit of quantification (10 ng/mL) in all horses and enalaprilat concentrations were below the limit of quantification in 4 of the 7 horses. Maximum mean ACE inhibitions from baseline were 88.38, 3.24, 21.69, 26.11 and 30.19% for IV enalapril at 0.50 mg/kg, placebo and PO enalapril at 0.50, 1.00 and 2.00 mg/kg, respectively. Blood pressures, SUN, creatinine and electrolytes remained unchanged during the experiments.

  • 无臭无味。
  • 易溶于水,微溶于乙腈。
  • 熔点为143~144.5℃。
  • 母体依那普利的旋光度 ([α]D25) -42.2°(C=1, 甲醇)。
  • pH值约为2.6,pKa1 = 3.0,pKa2 (25°C) = 5.4。

药理作用:

  • ACE抑制剂:作为血管紧张素转化酶的抑制剂,能减少血管紧张素Ⅱ的生成,从而扩张外周血管、降低血压。
  • 治疗高血压:适用于原发性、肾性高血压及恶性高血压等。同时可用于充血性心力衰竭和对其他药物无效或不能耐受的患者。
制备方法

马来酸依那普利主要通过两种方法制备:

  1. 缩合法

    • α-氧代苯丁酸乙酯与L-丙氨酰-L-脯氨酸二肽在4A分子筛催化下生成Schiff’s碱,再用氰硼氢化钠还原得到依那普利。
    • 该方法进一步可与马来酸形成盐。
  2. 一步法

    • α-溴代苯丁酸乙酯和L-丙氨酰-L-脯氨酸二肽在DMF、TEA条件下直接缩合,一步即可获得依那普利。
  3. 替代合成路径

    • 该方法涉及从苯出发制备β-苯甲酰丙烯酸及其衍生物的步骤。
      • 苯丁酸乙酯的制备。
      • 耦合反应生成所需二肽片段。
      • 氢化还原和其它后处理操作。
用途

马来酸依那普利是一种有效的血管紧张素转化酶抑制剂,广泛用于治疗高血压及充血性心力衰竭。此外,它也被用作复方药物成分之一(如Vaseretic),以提高疗效。

总之,通过上述不同的合成路径可以制备出高质量的马来酸依那普利,并且这种化合物在临床应用中表现出良好的效果。
