代谢
坎地沙坦西莱昔替尔在通过胃肠道吸收过程中通过酯水解迅速且完全地转化为坎地沙坦,坎地沙坦是一种选择性的AT1亚型血管紧张素II受体拮抗剂。坎地沙坦主要通过尿液和胆汁(经粪便)以原形排泄,经历少量肝脏代谢,通过脱乙基化转化为一种无活性的代谢物。
Candesartan cilexetil is rapidly and completely bioactivated by ester hydrolysis during absorption from the gastrointestinal tract to candesartan, a selective AT1 subtype angiotensin II receptor antagonist. Candesartan is mainly excreted unchanged in urine and feces (via bile). It undergoes minor hepatic metabolism by O-deethylation to an inactive metabolite.

毒理性
  • 毒性总结
识别和使用:坎地沙坦是一种白色至类白色粉末,制成口服片剂。坎地沙坦是血管紧张素II型1(AT1)受体的拮抗剂。它单独使用或与其他类别的抗高血压药物联合使用,用于成人及1至小于17岁儿童的血压管理。它还用于治疗成人心力衰竭,以减少心血管死亡和心力衰竭住院治疗。人类暴露和毒性:坎地沙坦过量的最可能表现包括低血压、眩晕和心动过速;由于副交感(迷走神经)刺激,可能会出现心动过缓。虽然坎地沙坦可用于高血压儿童,但不推荐用于1岁以下儿童,因为直接作用于肾素-血管紧张素系统(RAS)的药物可能会对未成熟肾脏的发育产生影响。坎地沙坦在妊娠期间的使用也是禁忌的。尽管在第一季度使用并不表明有主要畸形的危险,但在第二和第三季度使用可能会导致胎儿畸形和严重的胎儿和新生儿毒性。胎儿毒性效应可能包括无尿、羊水过少、胎儿颅骨发育不良、宫内生长受限、早产和动脉导管未闭。死产或新生儿死亡可能会发生。与无尿相关的羊水过少可能会导致胎儿肢体挛缩、颅面部畸形和肺发育不良。在子宫内接触坎地沙坦后,新生儿可能会出现严重的无尿和低血压,对压力剂和容量扩张均无反应。动物研究:当坎地沙坦口服给予小鼠时,没有发现致癌性的证据。同样,雄性和雌性大鼠的生育能力也未受到坎地沙坦的影响。当坎地沙坦口服给予怀孕小鼠,剂量高达1000 mg/kg时,未观察到母体毒性或对胎儿发育的负面影响。然而,给予大鼠的剂量低至10 mg/kg/天,与后代存活率降低和肾积水发生率增加有关。给予怀孕兔子的坎地沙坦口服剂量为3 mg/kg/天,引起了母体毒性(体重减轻和死亡),但对胎儿存活、胎儿体重或外部、内脏或骨骼发育没有不利影响。坎地沙坦及其O-脱乙基代谢物在体外中国仓鼠肺(CHL)染色体畸变试验中呈基因毒性阳性。两种化合物在 Ames 微生物突变试验或体外小鼠淋巴瘤细胞试验中均未呈阳性。坎地沙坦(而不是其O-脱乙基代谢物)还在小鼠微核试验中进行了体内评估,在中国仓鼠卵巢(CHO)基因突变试验中进行了体外评估,在这两种情况下结果均为阴性。坎地沙坦西列昔在 Ames 测试、体外小鼠淋巴瘤细胞和大鼠肝细胞非程序性 DNA 合成试验以及体内小鼠微核试验中进行了评估,每种情况下结果均为阴性。
IDENTIFICATION AND USE: Candesartan is a white to off white powder that is formulated into oral tablets. Candesartan is an angiotensin II type 1 (AT1) receptor antagonist. It is used alone or in combination with other classes of antihypertensive agents in the management of hypertension in adults and children from 1 to less than 17 years of age. It is also used for the treatment of heart failure in adults with left ventricular systolic dysfunction to reduce cardiovascular death and heart failure hospitalizations. HUMAN EXPOSURE AND TOXICITY: The most likely manifestations of candesartan overdose include hypotension, dizziness, and tachycardia; bradycardia could occur from parasympathetic (vagal) stimulation. While candesartan can be used in hypertensive children, it is not approved for use in children less one 1 year of age as drugs that act directly on the renin-angiotensin system (RAS) can have effects on the development of immature kidneys. The use of candesartan is also contraindicated during pregnancy. While use during the first trimester does not suggest a risk of major anomalies, use during the second and third trimester may cause teratogenicity and severe fetal and neonatal toxicity. Fetal toxic effects may include anuria, oligohydramnios, fetal hypocalvaria, intrauterine growth restriction, premature birth and patent ductus arteriosus. Stillbirth or neonatal death may occur. Anuria-associated oligohydramnios may produce fetal limb contractures, craniofacial deformation, and pulmonary hypoplasia. Severe anuria and hypotension, resistant to both pressor agents and volume expansion, may occur in the newborn following in utero exposure to candesartan. ANIMAL STUDIES: There was no evidence of carcinogenicity when candesartan was orally administered to mice. Also, the fertility of male and female rats was unaffected by administration of candesartan. No maternal toxicity or adverse effects on fetal development were observed when candesartan was administered to pregnant mice at oral doses up to 1000 mg/kg. However, doses as low as 10 mg/kg/day administered to rats were associated with reduced survival and an increased incidence of hydronephrosis in the offspring. Candesartan given to pregnant rabbits at an oral dose of 3 mg/kg/day caused maternal toxicity (decreased body weight and death) but had no adverse effects on fetal survival, fetal weight, or external, visceral, or skeletal development. Candesartan and its O-deethyl metabolite tested positive for genotoxicity in the in vitro Chinese hamster lung (CHL) chromosomal aberration assay. Neither compound tested positive in the Ames microbial mutagenesis assay or the in vitro mouse lymphoma cell assay. Candesartan (but not its O-deethyl metabolite) was also evaluated in vivo in the mouse micronucleus test and in vitro in the Chinese hamster ovary (CHO) gene mutation assay, in both cases with negative results. Candesartan cilexetil was evaluated in the Ames test, the in vitro mouse lymphoma cell and rat hepatocyte unscheduled DNA synthesis assays and the in vivo mouse micronucleus test, in each case with negative results.

吸收、分配和排泄
坎地沙坦的分布体积为0.13 L/kg。坎地沙坦与血浆蛋白高度结合(>99%)且不渗透红细胞。在远高于推荐剂量所达到的坎地沙坦血浆浓度范围内,蛋白结合是恒定的。在大鼠中,已经证明坎地沙坦几乎不穿过血脑屏障,如果有的话。在大鼠中也已经证明,坎地沙坦能够通过胎盘屏障,并在胎儿中分布。
The volume of distribution of candesartan is 0.13 L/kg. Candesartan is highly bound to plasma proteins (>99%) and does not penetrate red blood cells. The protein binding is constant at candesartan plasma concentrations well above the range achieved with recommended doses. In rats, it has been demonstrated that candesartan crosses the blood-brain barrier poorly, if at all. It has also been demonstrated in rats that candesartan passes across the placental barrier and is distributed in the fetus.

吸收、分配和排泄
服用坎地沙坦西莱昔替后,坎地沙坦的绝对生物利用度估计为15%。服药片后,血清中峰值浓度(Cmax)在3到4小时后达到。高脂肪含量的食物不会影响服用坎地沙坦西莱昔替后坎地沙坦的生物利用度。
Following administration of candesartan cilexetil, the absolute bioavailability of candesartan was estimated to be 15%. After tablet ingestion, the peak serum concentration (Cmax) is reached after 3 to 4 hours. Food with a high fat content does not affect the bioavailability of candesartan after candesartan cilexetil administration.

吸收、分配和排泄
坎地沙坦的总血浆清除率为0.37 mL/min/kg,其中肾清除率为0.19 mL/min/kg。当口服坎地沙坦时,约26%的剂量以原形通过尿液排出。在口服标记有(14)C的坎地沙坦西莱昔替后,大约33%的放射性物质在尿液中回收,大约67%在粪便中回收。在静脉注射标记有(14)C的坎地沙坦后,大约59%的放射性物质在尿液中回收,大约36%在粪便中回收。胆汁排泄有助于坎地沙坦的消除。
Total plasma clearance of candesartan is 0.37 mL/min/kg, with a renal clearance of 0.19 mL/min/kg. When candesartan is administered orally, about 26% of the dose is excreted unchanged in urine. Following an oral dose of (14)C-labeled candesartan cilexetil, approximately 33% of radioactivity is recovered in urine and approximately 67% in feces. Following an intravenous dose of (14)C-labeled candesartan, approximately 59% of radioactivity is recovered in urine and approximately 36% in feces. Biliary excretion contributes to the elimination of candesartan.

制备方法与用途

理化性质

坎地西坦(Candesartan)是坎地西坦酯的前药,在肾素-血管紧张素系统(RAS)中表现出色。作为继血管紧张素转换酶抑制剂(ACEI)之后的新一类药物,它通过选择性阻断循环系统和组织中的血管紧张素Ⅱ受体而具有更佳的降压效果及较少的不良反应,是一种有前景的抗高血压药。

药理及应用
  1. 坎地沙坦酯 在体内迅速水解成代谢物坎地沙坦。坎地沙坦作为血管紧张素Ⅱ受体(AT1)拮抗剂,通过与血管平滑肌AT1受体结合来对抗血管紧张素Ⅱ的血管收缩作用,从而降低末梢血管阻力。另外认为,坎地沙坦还可以通过抑制肾上腺醛固酮分泌发挥一定的降压效果。

  2. 临床试验 表明,在高血压患者中多次服用本品后,血浆肾素活性、血管紧张素Ⅰ浓度及血管紧张素Ⅱ浓度升高;每日1次连续用药2-8mg可使收缩压和舒张压下降,左室心肌重量减少,末梢血管阻力降低。但对心排出量、射血分数、肾血管阻力、肾血流量、肾小球滤过率无明显影响,并且在有脑血管障碍的原发性高血压患者中,对脑血流量没有显著影响。

适应症

坎地沙坦为血管紧张素Ⅱ拮抗剂药,适用于治疗原发性高血压。

化学性质
  • 化学结构:卡地沙坦酯(Candesartan Cilexetil)的分子式为C33H34N6O5。
  • 物理性质:无色结晶,熔点183-185℃。
合成路线
  1. 从化合物Ⅲ出发,经过多个步骤最终合成卡地沙坦:

    • 将10.4g 化合物Ⅲ溶于50ml乙醇,加入28.1g SnCl2?2H2O,在80℃搅拌2h。
    • 然后浓缩至干,剩余物溶于300ml乙酸乙酯,在冰浴冷和搅拌下滴加500ml 2mol/L NaOH。分出的水层用乙酸乙酯萃取两次,合并有机相,经干燥、浓缩及硅胶柱层析。
    • 最终得到7.3g无色结晶化合物Ⅳ(熔点104-105℃),收率79%。
  2. 经过进一步反应,最终制备出卡地沙坦:

    • 0.24g 化合物Ⅵ和1.5ml lmol/L NaOH溶于4ml乙醇,在80℃搅拌1h。
    • 浓缩后加入水和乙酸乙酯,分出水层,并用lmol/L盐酸调至pH=3-4后析出结晶。经乙酸乙酯-甲醇重结晶后得到0.15g无色结晶卡地沙坦(熔点183-185℃),收率67%。

以上步骤展示了合成过程中的关键反应及条件,确保了最终产物的高纯度和高效产出。

    摘要:
    奥美沙坦酯(OM)是一种前药类型的血管紧张素II 1型受体阻断剂(ARB)。我们最近鉴定出羧甲基烯酮合成酶同源物(CMBL)是人类中负责OM生物活化的酶。在本研究中,我们通过关注种间差异和组织特异性,比较了OM与其他前药类型的ARB,坎地沙坦环己酯(CC)和阿齐沙坦酯(AM)的生物活化特性。在采用小鼠、大鼠、猴、狗和人的组织亚细胞组分的体外实验中,除了狗的肠道(几乎没有活性)外,所有测试物种的肝细胞、肠细胞和肾细胞中都观察到显著的OM水解酶活性,而肺细胞中的活性相对较低。相比之下,肝微粒体表现出所有测试物种中各种组织亚细胞组分中的最高CC水解酶活性。通过Western印迹分析采用组织亚细胞组分,用人CMBL和羧酸酯酶1(CES1)抗体染色的条带强度很好地反映了动物和人类中的OM和AM水解酶活性和CC水解酶活性。人重组的CMBL和CES1表现出显著的AM和CC水解酶活性,而CC水解几乎不能通过重组的羧酸酯酶2(CES2)催化。总之,OM不仅在人类中通过肠道CMBL生物活化,而且在小鼠、大鼠和猴中也是如此,而CC通过肝CES1而非包括CES2在内的肠道酶生物活化。AM是CMBL的底物。
