代谢
已经确定,孟鲁司特高度代谢,通常是通过细胞色素P450 3A4、2C8和2C9同工酶。特别是,CYP2C8酶在药物代谢中发挥重要作用。然而,在治疗剂量下,成年和儿科患者的稳态血浆中孟鲁司特代谢物的浓度是检测不到的。
It has been determined that montelukast is highly metabolized and typically so by the cytochrome P450 3A4, 2C8, and 2C9 isoenzymes. In particular, it seems that the CYP2C8 enzymes play a significant role in the metabolism of the drug. Nevertheless, at therapeutic doses, the plasma concentrations of montelukast metabolites are undetectable at steady state in adults and pediatric patients.

代谢
蒙托鲁克司特的代谢命运尚未完全确定,但该药物在大肠和/或肝脏中广泛代谢并在胆汁中排泄。已经识别出几种代谢途径,包括酰基葡萄糖苷酸化以及由几种细胞色素P-450(CYP)同工酶催化的氧化反应。体外研究表明,微粒体P-450同工酶CYP3A4是形成21-羟基代谢物(M5)和一种亚砜代谢物(M2)的主要酶,而CYP2C9是形成36-羟基代谢物(M6)的主要同工酶。其他已识别的代谢物包括一种酰基葡萄糖苷酸(M1)和一种25-羟基(一种酚,M3)类似物。
The metabolic fate of montelukast has not been fully determined, but the drug is extensively metabolized in the GI tract and/or liver and excreted in bile. Several metabolic pathways have been identified including acyl glucuronidation, and oxidation catalyzed by several cytochrome P-450 (CYP) isoenzymes. In vitro studies indicate that the microsomal P-450 isoenzyme CYP3A4 is the major enzyme involved in formation of the 21-hydroxy metabolite (M5) and a sulfoxide metabolite (M2), and CYP2C9 is the major isoenzyme involved in the formation of the 36-hydroxy metabolite (M6). Other identified metabolites include an acyl glucuronide (M1) and a 25-hydroxy (a phenol, M3) analog.

代谢
在口服54.8毫克放射性标记的孟鲁司特后,药物代谢物占循环中放射性活性的不到2%。在放射性研究中,已识别出的孟鲁司特代谢物包括21-羟基(苄基酸的对映异构体,M5a和M5b)和36-羟基(甲醇的对映异构体,M6a和M6b)代谢物。在成人和儿童口服治疗剂量的孟鲁司特后,稳态下血浆中代谢物的浓度低于检测水平。
Following oral administration of 54.8 mg of radiolabeled montelukast, metabolites of the drug represented less than 2% of circulating radioactivity. Montelukast metabolites that have been identified in plasma in radiolabeled studies include the 21-hydroxy (diastereomers of a benzylic acid, M5a and M5b) and the 36-hydroxy (diastereomers of a methyl alcohol, M6a and M6b) metabolites. Following oral administration of therapeutic doses of montelukast, plasma concentrations of metabolites at steady-state in adults and children were below the level of detection.

毒理性
  • 肝毒性
在临床试验中,长期服用孟鲁司特的患者中有1%到2%的人出现了血清转氨酶水平的轻度升高,但在匹配的安慰剂接受者中也有类似的报道率。ALT异常通常是轻度的、无症状的,并且是自限性的。临床上明显的孟鲁司特引起的肝损伤是罕见的;但文献中报告了超过十几例。在这些病例中,损伤发作的潜伏期差异很大,从几天到几年不等。患者表现为食欲不振、恶心、右上象限疼痛、深色尿和黄疸。酶升高的模式通常是混合型的,但已报道了肝细胞损伤或胆汁淤积模式。过敏特征和自身抗体的形成是罕见的。嗜酸性粒细胞增多症经常被报道,但这可能是由基础过敏状况而不是肝损伤引起的。停止药物后,损伤通常在1到4个月内得到解决。
In clinical trials, mild elevations in serum aminotransferase levels were found in 1% to 2% of patients taking montelukast chronically, but similar rates are reported in matched placebo recipients. The ALT abnormalities were usually mild, asymptomatic and self limited. Clinically apparent liver injury from montelukast is rare; but more than a dozen cases reported in the literature. In these cases, the latency to onset of injury was highly variable, ranging from a few days to several years. Patients presented with anorexia, nausea, right upper quadrant pain, dark urine, and jaundice. The pattern of enzyme elevation was usually mixed, but both hepatocellular or cholestatic patterns have been reported. Allergic features and autoantibody formation were rare. Eosinophilia was often reported, but this may have been due to the underlying allergic condition rather than the liver injury. The injury usually resolved within 1 to 4 months of stopping the drug.

吸收、分配和排泄
  • 吸收
已经观察到,口服给药后,孟鲁司特(montelukast)能够迅速吸收。该药物的口服生物利用度为64%。此外,似乎早晨正常用餐或晚上摄入高脂肪零食都不会影响孟鲁司特的吸收。
It has been observed that montelukast is quickly absorbed following administration by the oral route. The oral bioavailability documented for the drug is 64%. Furthermore, it seems that having a regular meal in the morning or even a high fat snack in the evening does not affect the absorption of montelukast.

蒙托鲁斯特从胃肠道快速吸收,空腹状态下单次口服10毫克薄膜包衣片(成人)、5毫克咀嚼片(成人)或4毫克咀嚼片(2至5岁儿童)后,分别在3-4、2-2.5或2小时内达到血浆峰浓度。... 早晨与4毫克口服颗粒剂一同摄入高脂肪餐对蒙托鲁斯特的药时曲线下面积(AUC)没有影响;然而,达到血浆峰浓度的时间从2.3小时延长到6.4小时,血浆峰浓度降低了35%。
Montelukast is rapidly absorbed from the GI tract, and peak plasma concentrations are attained within 3-4, 2-2.5, or 2 hours following oral administration in the fasted state of a single 10-mg film-coated (in adults), 5-mg chewable (in adults), or 4-mg chewable (in children 2-5 years of age) tablet, respectively. ... Ingestion of a high-fat meal in the morning with the 4-mg oral granules formulation had no effect on the AUC of montelukast; however, the time to peak plasma concentrations was prolonged from 2.3 hours to 6.4 hours and peak plasma concentrations were reduced by 35%.

制备方法与用途

哮喘治疗药 - 孟鲁司特

孟鲁司特是一种强效口服制剂,属于白三烯受体拮抗剂,能显著改善哮喘炎症指标。它通过抑制体内的白三烯而发挥作用,特别是对I型半胱氨酰白三烯受体有高度的亲和性和选择性,能够有效地抑制由LTC4、LTD4和LTE4产生的生理效应。

目前临床上用于15岁及以上成人哮喘的预防和长期治疗。它不仅可以预防白天和夜间的哮喘症状,还能减轻对阿斯匹林敏感的哮喘患者的症状,并用于缓解季节性过敏性鼻炎引起的打喷嚏、鼻塞、流涕和鼻痒等症状。

生物活性

Montelukast作为白三烯受体拮抗剂,适用于哮喘的持续治疗以及减少季节性过敏症状。它能有效保护肝脏免受损害,减轻过敏反应,并改善呼吸道炎症。

制备方法

孟鲁司特的合成过程复杂且步骤繁多,包括多个化学反应和纯化步骤。以下是主要步骤:

  1. 第一步:通过一系列有机反应得到化合物Ⅲ。
  2. 第二步:在低温条件下进行硼烷还原反应生成化合物Ⅳ。
  3. 第三步:使用锂化试剂对化合物Ⅳ进行官能团转化,形成化合物Ⅴ。
  4. 第四步:进行硅烷化和磷酰氯化反应,得到化合物Ⅵ。
  5. 第五步:通过环合和氟代反应生成化合物Ⅶ。
  6. 第六步:再经过一系列保护基操作及还原反应,最终获得中间体化合物Ⅷ。
  7. 第七步:进行甲磺酰化和肼解反应,得到目标产物莫特司特。

整个过程复杂且需要精确控制化学条件以确保高收率。通过上述步骤合成的孟鲁司特单钠盐是哮喘治疗的有效药物之一。
