代谢

氟西汀在摄入后会被CYP1A2、CYP2B6、CYP2C9、CYP2C19、CYP2D6、CYP3A4和CYP3A5代谢成诺氟西汀。尽管所有提到的酶都参与了氟西汀的N-脱甲基化，但CYP2D6、CYP2C9和CYP3A4似乎是I期代谢的主要贡献酶。此外，有证据表明CYP2C19和CYP3A4介导了氟西汀和诺氟西汀的O-脱烷基化，产生对三氟甲基苯酚，随后被代谢成马尿酸。氟西汀和诺氟西汀都经历葡萄糖苷酸化以促进排泄。值得注意的是，母药和活性代谢物都抑制CYP2D6同种型，因此接受氟西汀治疗的患者容易发生药物相互作用。

Fluoxetine is metabolized to norfluoxetine by CYP1A2, CYP2B6, CYP2C9, CYP2C19, CYP2D6, CYP3A4, and CYP3A5 upon ingestion. Although all of the mentioned enzymes contribute to N-demethylation of fluoxetine, CYP2D6, CYP2C9 and CYP3A4 appear to be the major contributing enzymes for phase I metabolism. In addition, there is evidence to suggest that CYP2C19 and CYP3A4 mediate O-dealkylation of fluoxetine and norfluoxetine to produce para-trifluoromethylphenol which is subsequently metabolized to hippuric acid. Both fluoxetine and norfluoxetine undergo glucuronidation to facilitate excretion. Notably, both the parent drug and active metabolite inhibit CYP2D6 isozymes, and as a result patients who are being treated with fluoxetine are susceptible to drug interactions.

代谢

氟西汀已知的人体代谢物包括去甲氟西汀、对三氟甲基苯酚以及(2S,3S,4S,5R)-3,4,5-三羟基-6-[甲基-[3-苯基-3-[4-(三氟甲基)苯氧基]丙基]氨基]氧杂环己烷-2-羧酸。

Fluoxetine has known human metabolites that include Norfluoxetine, p-Trifluoromethyl phenol, and (2S,3S,4S,5R)-3,4,5-trihydroxy-6-[methyl-[3-phenyl-3-[4-(trifluoromethyl)phenoxy]propyl]amino]oxane-2-carboxylic acid.

代谢

动物研究中有限的数据表明，氟西汀可能会经历首过代谢，可能通过肝脏和/或肺部发生。氟西汀似乎被广泛代谢，很可能在肝脏中，转化为去甲氟西汀和其他代谢物。去甲氟西汀是主要的活性代谢物，通过氟西汀的N-脱甲基作用形成。去甲氟西汀的药理效力似乎与氟西汀相当。氟西汀和去甲氟西汀都在肝脏中进行第II阶段葡萄糖苷酸化反应。还认为氟西汀和去甲氟西汀经历O-脱烷基化反应，形成对-三氟甲基苯酚，然后进一步代谢为马尿酸。 消除途径：主要的消除途径似乎是肝脏代谢为无活性代谢物，由肾脏排出。S-对映体消除得更慢，是在稳态下存在的主要对映体。 半衰期：1-3天（急性给药）；4-6天（慢性给药）；4-16天（去甲氟西汀，急性给药和慢性给药）。

Limited data from animal studies suggest that fluoxetine may undergo first-pass metabolism may occur via the liver and/or lungs. Fluoxetine appears to be extensively metabolized, likely in the liver, to norfluoxetine and other metabolites. Norfluoxetine, the principal active metabolite, is formed via <i>N</i>-demethylation of fluoxetine. Norfluoxetine appears to be comparable pharmacologic potency as fluoxetine. Fluoxetine and norfluoxetine both undergo phase II glucuronidation reactions in the liver. It is also thought that fluoxetine and norfluoxetine undergo <i>O</i>-dealkylation to form <i>p</i>-trifluoromethylphenol, which is then subsequently metabolized to hippuric acid. Route of Elimination: The primary route of elimination appears to be hepatic metabolism to inactive metabolites excreted by the kidney. The S-enantiomer is eliminated more slowly and is the predominant enantiomer present at steady state. Half Life: 1-3 days [acute administration]; 4-6 days [chronic administration]; 4-16 days [norfluoxetine, acute and chronic administration].

毒理性

• 毒性总结

氟西汀是一种胆碱酯酶或乙酰胆碱酯酶（AChE）抑制剂。胆碱酯酶抑制剂（或称'抗胆碱酯酶'）抑制乙酰胆碱酯酶的作用。由于其基本功能，干扰乙酰胆碱酯酶作用的化学物质是强效的神经毒素，在低剂量下会导致过度流涎和流泪，随后是肌肉痉挛，最终导致死亡。神经毒气和许多用于杀虫剂的物质已被证明通过绑定乙酰胆碱酯酶活性位点上的丝氨酸，完全抑制该酶。乙酰胆碱酯酶分解神经递质乙酰胆碱，后者在神经和肌肉接点处释放，以使肌肉或器官放松。乙酰胆碱酯酶抑制的结果是乙酰胆碱积累并持续作用，使得任何神经冲动不断传输，肌肉收缩不会停止。最常见的乙酰胆碱酯酶抑制剂之一是磷基化合物，这些化合物被设计用于绑定到酶的活性位点。结构要求是一个带有两个亲脂性基团、一个离去基团（如卤素或硫氰酸酯）以及一个端氧原子的磷原子。

Fluoxetine is a cholinesterase or acetylcholinesterase (AChE) inhibitor. A cholinesterase inhibitor (or 'anticholinesterase') suppresses the action of acetylcholinesterase. Because of its essential function, chemicals that interfere with the action of acetylcholinesterase are potent neurotoxins, causing excessive salivation and eye-watering in low doses, followed by muscle spasms and ultimately death. Nerve gases and many substances used in insecticides have been shown to act by binding a serine in the active site of acetylcholine esterase, inhibiting the enzyme completely. Acetylcholine esterase breaks down the neurotransmitter acetylcholine, which is released at nerve and muscle junctions, in order to allow the muscle or organ to relax. The result of acetylcholine esterase inhibition is that acetylcholine builds up and continues to act so that any nerve impulses are continually transmitted and muscle contractions do not stop. Among the most common acetylcholinesterase inhibitors are phosphorus-based compounds, which are designed to bind to the active site of the enzyme. The structural requirements are a phosphorus atom bearing two lipophilic groups, a leaving group (such as a halide or thiocyanate), and a terminal oxygen.

毒理性

• 肝毒性

肝脏测试异常在服用氟西汀的患者中很少见（少于1%），而且升高的程度通常较轻，通常不需要调整剂量或停药。在服用氟西汀的患者中，有报道称罕见出现急性、临床上明显的肝脏损伤，伴有显著肝酶升高，可伴有或不伴有黄疸。损伤的发生通常在2到12周内，血清酶升高的模式通常是肝细胞型的，但也有描述了混合型和胆汁淤积型损伤的令人信服的病例。自身免疫（自身抗体）和免疫过敏特征（皮疹、发热、嗜酸性粒细胞增多）不常见。

Liver test abnormalities have been reported to occur rarely in patients on fluoxetine (less than 1%), and elevations are usually modest and usually do not require dose modification or discontinuation. Rare instances of acute, clinically apparent episodes of liver injury with marked liver enzyme elevations with or without jaundice have been reported in patients on fluoxetine. The onset of injury is usually within 2 to 12 weeks and the pattern of serum enzyme elevations is usually hepatocellular, but convincing cases of mixed and cholestatic injury have also been described. Autoimmune (autoantibodies) and immunoallergic features (rash, fever, eosinophilia) are uncommon.

吸收、分配和排泄

• 吸收

氟西汀的口服生物利用度小于90%，这是由于肝脏首过代谢的结果。在一项生物等效性研究中，已确立的参考制剂中氟西汀20毫克的Cmax（最高血药浓度）为11.754纳克/毫升，而拟议的通用制剂的Cmax为11.786纳克/毫升。氟西汀非常亲脂并且与血浆蛋白高度结合，这使得药物及其活性代谢物去甲氟西汀能够分布到大脑中。

The oral bioavailability of fluoxetine is <90% as a result of hepatic first pass metabolism. In a bioequivalence study, the Cmax of fluoxetine 20 mg for the established reference formulation was 11.754 ng/mL while the Cmax for the proposed generic formulation was 11.786 ng/ml. Fluoxetine is very lipophilic and highly plasma protein bound, allowing the drug and it's active metabolite, norfluoxetine, to be distributed to the brain.

制备方法与用途

抗抑郁药——氟西汀

**氟西汀**是一种选择性血清再吸收抑制剂（SSRI）型的抗抑郁药，其化学名称为盐酸氟西汀（Fluoxetine hydrochloride），商品名包括“百优解”或“百忧解”（Prozac）。由美国礼来公司研发，并于20世纪90年代上市。该药物主要用于治疗成人抑郁症、强迫症、神经性贪食症以及具有或不具广场恐惧症的惊恐症，因其良好的抗抑郁效应而被广泛应用于临床。

氟西汀的主要药理作用是选择性地抑制中枢神经系统突触前释放的5-羟色胺（5-HT）的再摄取。它几乎不对α-肾上腺素能、β-肾上腺素能、5-羟色胺能、多巴胺能等其他受体产生结合力。

氟西汀口服后能够良好地从胃肠道吸收，大约6～8小时达到血浆浓度峰值，进食不会显著影响其生物利用度。它在肝脏中被代谢成多种产物，并通过尿液排出体外。服用期间可能会出现恶心、失眠、口干等副作用，但大多数情况下这些症状会随着时间的推移而逐渐减轻。

氟西汀的合成方法

方法一

1. 通过Mannich反应生成β-甲氨基苯丙酮的盐酸盐。
2. 将仲胺在碳酸钾水溶液中溶解，加入乙醇并逐步加入硼氢化钾。
3. 减压蒸除乙醇后，用乙醚和氯仿萃取剩余液。调整pH值至8.0后干燥。
4. 通过重结晶纯化N-甲基-3-苯基-3-羟基丙胺（收率89.7%）。
5. 该仲胺溶于DMAC，加入氢化钠并升温至70℃保温。再加入碘化钾和对氯三氟甲苯，在90℃反应后加水稀释，并用乙醚萃取。
6. 将提取液调整pH值至1.0放置析晶，过滤并干燥。最后通过乙酸乙酯重结晶得到盐酸氟西汀（收率80%，熔点152～153℃）。

方法二

1. β-甲氨基苯丙酮经硼烷还原成醇后氯化生成3-甲氨基-1-苯基-1-丙醇。
2. 该醇与对三氟苯酚钠反应，最终得到氟西汀。

方法三

1. 在温和条件下使用溴化氰处理N,N-二甲基-3-(4-三氟甲基苯氧基)-3-苯基丙胺，并在室温下继续进行。
2. 将产物溶于氢氧化钾、乙二醇和水的混合物中，在130℃回流反应20小时。
3. 冷却后加入乙醚提取，调整pH值至8.0后进一步处理，最后通过重结晶得到氟西汀（收率64%）。

以上就是关于氟西汀的一些基本信息和合成方法。请注意，使用任何药物都应在医生指导下进行，并且严格按照医嘱服用。

  An assembly of structurally diverse small and simple 5-aminomethylene derivatives of 2,4-thiazolidinedione and studies of their biological activity

  摘要：

  The synthesis of a novel series of substituted 5-(aminomethylene)thiazolidine-2,4-diones was achieved using a wide range of heterocyclic models derived from eight drug-like molecules. The primary aim of this study was to combine medicinally known, biologically active molecules bearing a 2A degrees amine functionality, such as terbinafine, fluoxetine, atomoxetine, cetirizine, risperidone, aripiprazole, ziprasidone, and clopidogrel, with a thiazolidinedione ring via an amino-methylene linker. By targeting this synergistic approach to compounds with skeletal, functional, and stereochemical diversity, we have developed a simple synthetic concept to enrich the thiazolidinedione collection with various biological activities. The biological activities of the newly synthesized 5-(aminomethylene)thiazolidine-2,4-dione derivatives were explored. All compounds were found to have antibacterial activity, with compounds bearing pyridine or piperazine moieties showing good to excellent antibacterial activity. Compounds with piperazine moieties were also found to show good antifungal activity, whereas none of the synthesized compounds showed high cytotoxic activity.
