代谢
白消安在肝脏中广泛代谢。白消安主要通过与谷胱甘肽结合进行代谢,包括自发结合和通过谷胱甘肽S-转移酶(GST)催化。GSTA1是促进白消安代谢的主要GST同种型。其他涉及的GST同种型还包括GSTM1和GSTP1。已经鉴定出至少12种代谢物,其中确定了四氢噻吩、四氢噻吩12-氧化物、磺酰环己烷和3-羟基磺酰环己烷。这些代谢物不具有细胞毒性。
Busulfan is extensively metabolizes in the hepatic. Busulfan is predominantly metabolized by conjugation with glutathione, both spontaneously and by glutathione S-transferase (GST) catalysis. GSTA1 is the primary GST isoform that facilitates the the metabolism of busulfan. Other GST isoforms that are also involved are GSTM1 and GSTP1. At least 12 metabolites have been identified among which tetrahydrothiophene, tetrahydrothiophene 12-oxide, sulfolane, and 3-hydroxysulfolane were identified. These metabolites do not have cytotoxic activity.

代谢
在大鼠、兔和鼠标中注射2:3-(14)C-Myleran后,发现60%的尿液中放射性物质以3-羟基四氢噻吩-1,1-二氧化物的形式存在,这是一种亚磺酰化物。推测Myleran在体内与半胱氨酸或半胱氨酰基团发生反应,形成环状磺酰铵离子,然后环状磺酰铵离子裂解成四氢噻吩,氧化成1,1-二氧化物,并通过生物羟基化作用形成3-羟基化合物。
After IP injections of 2:3-(14)C-Myleran in the rat, rabbit and mouse, 60% of the urinary radioactivity was found to be in the form of the 3-hydroxy tetrahydrothiophene-1,1-dioxide, a sulphone. It is suggested that in vivo Myleran undergoes a reaction with cysteine or a cysteinyl moiety to form a cyclic sulphonium ion, which in turn undergoes cleavage to the tetrahydrothiophene, oxidation to the 1,1-dioxide and biological hydroxylation to the 3-hydroxy compound.

代谢
在大鼠和小鼠中,单次通过腹膜内注射用花生油稀释的米勒兰-(35)S(10毫克/千克体重)的50-60%在24到48小时内被排泄,主要作为甲烷磺酸;尿液中还含有少量未改变的米勒兰和两个未识别的成分。在兔中,尿液中只发现了甲烷磺酸这一代谢物。
In the rat and mouse 50-60% of a single dose of Myleran-(35)S (10 mg/kg bw) injected intraperitoneally in arachis oil was excreted within 24 to 48 hours, mainly as methane sulphonic acid; a small amount of unchanged Myleran and two unidentified components were present. In the rabbit, methane sulphonic acid was the only metabolite found in the urine.

代谢
环磷酰胺的代谢命运已经在老鼠和人类中通过使用(14)C-和(35)S-标记的材料进行了研究。在人类中,与老鼠一样,几乎所有的(35)S-标记的环磷酰胺的放射性都以(35)S-甲磺酸的形式通过尿液排出。已经证明,在老鼠体内形成甲磺酸的过程并不是由于环磷酰胺简单水解成1,4-丁二醇,因为只有大约4%的2,3-(14)C-环磷酰胺以二氧化碳的形式排出,而2,3-(14)C-1,4-丁二醇几乎全部转化为二氧化碳。环磷酰胺在老鼠体内的主要反应是与巯基团(特别是半胱氨酸和含半胱氨酸的化合物)的烷基化反应,产生一个环状硫正离子化合物,这是分子中4-碳部分的主要尿代谢物,3-羟基四氢噻吩-1,1-二氧化物的前体。这被称为环磷酰胺的“硫剥离”作用,它可能改变某些含硫氨基酸、多肽和蛋白质的功能;这种作用是否对环磷酰胺的细胞毒性有重要贡献尚不清楚。
The metabolic fate of busulfan has been studied in rats and humans using (14)C- and (35)S-labeled materials. In humans, as in the rat, almost all of the radioactivity in (35)S-labeled busulfan is excreted in the urine in the form of (35)S-methanesulfonic acid. /It was/ demonstrated that the formation of methanesulfonic acid in vivo in the rat is not due to a simple hydrolysis of busulfan to 1,4-butanediol, since only about 4% of 2,3-(14)C-busulfan was excreted as carbon dioxide, whereas 2,3-(14)C-1,4-butanediol was converted almost exclusively to carbon dioxide. The predominant reaction of busulfan in the rat is the alkylation of sulfhydryl groups (particularly cysteine and cysteine-containing compounds) to produce a cyclic sulfonium compound which is the precursor of the major urinary metabolite of the 4-carbon portion of the molecule, 3-hydroxytetrahydrothiophene-1,1-dioxide. This has been termed a "sulfur-stripping" action of busulfan and it may modify the function of certain sulfur-containing amino acids, polypeptides, and proteins; whether this action makes an important contribution to the cytotoxicity of busulfan is unknown.

代谢
(14)C白消安以ip方式(15 mg/kg)给药给了5只雄性Sprague-Dawley大鼠。在72小时内,(14)C的尿液回收率约为总剂量的70%,而粪便排泄率在1.5-2%之间。通过结合高效液相色谱(HPLC)和放射性检测池尿液,研究了白消安尿液中代谢物的模式。至少可以分离出八个放射性组分。通过气相色谱/质谱(GC/MS)和核磁共振光谱法鉴定出三个主要代谢物峰:3-羟基磺酰亚胺(占总尿液放射性的39%)、四氢噻吩1-氧化物(20%)和磺酰亚胺(13%)。还鉴定出了白消安(6%)和四氢呋喃(2%)。假设另一个代谢物是亚磺酸离子谷胱甘肽结合物,但由于它非常不稳定,因此没有分离出来。然而,观察到了另一种化合物。这种代谢物与白消安与N-乙酰-L-半胱氨酸反应得到的亚磺酸离子共洗脱,并在水解时产生四氢噻吩。最后,在体外测试了白消安及其三个主要代谢物对中国V79仓鼠细胞的细胞毒性。只有白消安诱发了细胞毒性,这表明体内的细胞毒性是由母化合物介导的,正如预期的那样。
(14)C busulfan was administered ip (15 mg/kg) to 5 male Sprague-Dawley rats. For 72 hours, the urinary recovery of (14)C was approximately 70% of the total dose, while the fecal excretion was within the range 1.5-2%. The pattern of the urinary metabolites of busulfan was studied by HPLC in combination with radioactivity detection of the pooled urine. At least eight radioactive fractions could be separated. Three major metabolite peaks were identified by GC/MS and NMR spectroscopy: 3-hydroxysulfolane (39% of total urine radioactivity), tetrahydrothiophene 1- oxide (20%), and sulfolane (13%). Busulfan (6%) and tetrahydrofuran (2%) were also identified. A sulfonium ion glutathione conjugate was hypothesised as another metabolite, but was not isolated because it was very unstable. However, another compound was observed. This metabolite co-eluted with the sulfonium ion obtained of the reaction of busulfan with N-acetyl-L-cysteine and produced tetrahydrothiophene when hydrolyzed. Finally, busulfan and the three main metabolites were tested for cytotoxicity on Chinese V79 hamster cells in vitro. Cell toxicity was induced only by busulfan, which indicates that the cytotoxicity in vivo is mediated by the parent compound, as expected.

  • 毒性总结
硫酸长春新碱是一种含有2个不稳定甲磺酸基团的烷基化剂,这两个基团分别连接在一个4碳烷基链的两端。一旦硫酸长春新碱被水解,甲磺酸基团会被释放出来,产生碳正离子。这些碳正离子会烷基化DNA,从而干扰DNA复制和RNA转录,最终导致核酸功能的中断。具体来说,它的作用机制是通过烷基化产生鸟嘌呤-腺嘌呤同链交联。这是通过SN2反应发生的,其中相对亲核的鸟嘌呤N7攻击紧邻甲磺酸离开基团的碳。这种类型的损伤无法通过细胞机制修复,因此细胞会经历凋亡。
Busulfan is an alkylating agent that contains 2 labile methanesulfonate groups attached to opposite ends of a 4-carbon alkyl chain. Once busulfan is hydrolyzed, the methanesulfonate groups are released and carbonium ions are produced. These carbonium ions alkylate DNA, which results in the interference of DNA replication and RNA transcription, ultimately leading to the disruption of nucleic acid function. Specifically, its mechanism of action through alkylation produces guanine-adenine intrastrand crosslinks. This occurs through an SN2 reaction in which the relatively nucleophilic guanine N7 attacks the carbon adjacent to the mesylate leaving group. This kind of damage cannot be repaired by cellular machinery and thus the cell undergoes apoptosis.

  • 肝毒性
口服白消安治疗与血清酶水平升高率低有关,通常是短暂的、轻微的,通常不需要调整剂量。长期服用口服白消安的患者中,出现临床明显的急性肝病的罕见病例已被描述。损伤的出现通常在治疗多年后,血清酶升高的模式通常是胆汁淤积性的(案例1)。至少有一例胆汁淤积性损伤报告导致肝衰竭。 可能使白消安治疗期间肝酶升高解释复杂化的问题是,长期使用白消安与结节性再生性增生病例有关。这一过程也至少在白消安或抗代谢药物(硫唑嘌呤、硫鸟嘌呤)治疗六个月到数年后出现,通常表现为门静脉高压(静脉曲张、静脉曲张出血、腹水)的迹象和最小的、非特异性症状以及血清酶升高。血小板减少几乎总是存在,往往是发展为门静脉高压的第一个迹象。停止使用抗肿瘤或免疫抑制治疗后,结节性再生通常在几周到几个月内开始改善。然而,在一些病例中,门静脉高压的并发症可能是严重的,如果并发败血症或其他器官衰竭,可能会导致肝衰竭(案例2)。 最后,也是最重要的一点是,高剂量静脉注射白消安联合全身照射、环磷酰胺或其他烷化剂,为骨髓或干细胞移植(造血细胞移植,HCT)做准备,已与 sinusoidal obstruction syndrome (SOS,以前被称为静脉阻塞性疾病)有关。损伤的出现通常在HCT后的10到20天内,表现为腹痛、肝触痛、因液体潴留而体重增加和黄疸。使用一些较新的条件方案,sinusoidal obstruction syndrome可能会在HCT后30到75天出现。血清酶通常升高,通常伴有血清转氨酶水平(和乳酸脱氢酶)显著升高,但碱性磷酸酶升高幅度较小。在严重病例中,会有肝肿大和腹水,肝衰竭的迹象出现。sinusoidal obstruction syndrome往往病情严重,死亡率可能高达50%。预后不良的迹象是血清ALT水平显著升高和高胆红素水平。在致命的情况下,多器官衰竭的死亡可能在发病后几天到几周内出现。在自发恢复的病例中,可能会有残留的纤维化或结节性再生。自身抗体形成和过敏表现不常见,尽管可能在发病时出现发热。发展sinusoidal obstruction syndrome的风险因素包括更高剂量的白消安、与环磷酰胺和全身照射联合使用、有利于更高白消安或环磷酰胺暴露的药物代谢动力学,以及预先存在的肝病,特别是慢性丙型肝炎。HCT后sinusoidal obstruction syndrome的发生率从20%到50%不等,但在近年来,随着使用较少侵略性的条件方案、更好地控制药物剂量和降低丙型肝炎的频率(通过对抗HCV测试所有献血者的消除输血后肝炎),其发生率已显著下降。 可能性评分:A(已知的临床明显肝损伤的原因,通常是由于为造血细胞移植准备骨髓清除而给予高剂量药物的直接毒性,很少是由于特异质性肝损伤)。
Oral busulfan therapy is associated with a low rate of serum enzyme elevations that are typically transient, mild and usually do not require dose adjustment. Rare instances of clinically apparent acute liver disease have been described in patients taking oral busulfan long term. The onset of injury is usually after years of therapy, and the pattern of serum enzyme elevations is usually cholestatic (Case 1). At least one case of cholestatic injury was reported to lead to hepatic failure. Perhaps complicating the issue of interpretation of liver enzyme elevations during busulfan therapy is that chronic use of busulfan has been linked to cases of nodular regenerative hyperplasia. This process also arises at least six months if not years of therapy with busulfan or antimetabolites (azathioprine, thioguanine) and typically presents with signs of portal hypertension (varices, variceal hemorrhage, ascites) and minimal, nonspecific symptoms and serum enzyme elevations. Thrombocytopenia is almost always present and is often the first sign of evolving portal hypertension. Nodular regeneration usually starts to improve within a few weeks to months of stopping the antineoplastic or immunosuppressive therapy. However, in some cases the complications of portal hypertension are severe and can result in hepatic failure particularly if complicated by septicemia or other organ failure (Case 2). Finally, and most importantly, busulfan given in high doses intravenously combined with total body irradiation, cyclophosphamide, or other alkylating agents in preparation for either bone marrow or stem cell transplantation (hematopoietic cell transplantation, HCT) has been linked to sinusoidal obstruction syndrome (SOS, formerly referred to as veno-occlusive disease). The onset of injury is usually within 10 to 20 days of HCT and presents with abdominal pain, liver tenderness, weight gain due to fluid accumulation, and jaundice. With some newer conditioning regimens, sinusoidal obstruction syndrome can present later, 30 to 75 days after HCT. The serum enzymes are usually elevated, typically with marked increases in serum aminotransferase levels (and lactic dehydrogenase), but minimal increases in alkaline phosphatase. In severe cases, there is hepatomegaly and ascites and signs of hepatic failure arise. Sinusoidal obstruction syndrome tends to be severe and the fatality rate can be as high as 50%. Poor prognostic signs are marked increases in serum ALT levels and high bilirubin levels. In fatal instances, death from multiorgan failure arises within days to weeks of onset. In cases with spontaneous recovery, there may be residual fibrosis or nodular regeneration. Autoantibody formation and allergic manifestations are uncommon, although fever may be present at onset. Risk factors for the development of sinusoidal obstruction syndrome are higher doses of busulfan, combination with cyclophosphamide and total body irradiation, pharmacokinetics that favor higher busulfan or cyclophosphamide exposure, and preexisting liver disease, particularly chronic hepatitis C. The frequency of sinusoidal obstruction syndrome after HCT ranges from 20% to 50%, but its incidence has decreased markedly in recent years with use of less aggressive conditioning regimens, better control over drug dosing, and lower frequency of hepatitis C (with elimination of posttransfusion hepatitis after anti-HCV testing of all blood donors). Likelihood score: A (well known cause of clinically apparent liver injury, generally as a result of direct toxicity from high doses given for myeloablation in preparation for hematopoietic cell transplantation and rarely due to idiosyncratic liver injury).

完全从胃肠吸收。白消安是一种小分子、高度脂溶性的药物,可以穿过血脑屏障。如果给成年患者单次静脉注射2毫克的负荷量,其绝对生物利用度为80% ± 20%。在儿童(1.5 - 6岁)中,绝对生物利用度为68% ± 31%。当患者口服单次剂量时,药时曲线下面积(AUC)为130 ng•hr/mL。口服给药后的峰值血浆浓度为30 ng/mL(在剂量标准化到2毫克之后)。在剂量标准化到4毫克后,需要0.9小时达到峰值血浆浓度。
Completely absorbed from the gastrointestinal tract. Busulfan is a small, highly lipophilic molecule that crosses the blood-brain-barrier. The absolute bioavailability, if a single 2 mg IV bolus injection is given to adult patients, is 80% ± 20%. In children (1.5 - 6 years old), the absolute bioavailability was 68% ± 31%. When a single oral dose is given to patients, the area under the curve (AUC) was 130 ng•hr/mL. The peak plasma concentration when given orally is 30 ng/mL (after dose normalization to 2 mg). It takes 0.9 hours to reach peak plasma concentration after dose normalization to 4 mg.

白消安主要用于抗肿瘤治疗,是细胞周期非特异性药物,主要针对G1期和M期。低剂量时它能够抑制骨髓粒细胞的生成,但对红细胞和淋巴细胞的影响较小。高剂量时同样会抑制这些细胞的生成。由于其选择性作用,白消安对慢性粒细胞白血病疗效显著,缓解率可达80-90%。然而,在急性变时应立即停药。

副作用

白消安具有一定的毒性,可能引发间断性肺纤维化、色素沉着、癫痫发作、肝静脉阻塞症和恶病质等症状。此外,它还能导致血小板减少,并长期使用会导致骨髓抑制甚至再生障碍性贫血。根据国际癌症研究机构(IARC)的分类,白消安被列为1类致癌物。

生物活性

Busulfan是一种细胞周期非特异性烷化剂抗肿瘤药,可诱导凋亡。在体外研究中,它能够抑制cobblestone区域形成细胞的频率,并通过依赖细胞凋亡的机制减少造血干细胞和祖细胞的生成。此外,Busulfan还能以时间依赖的方式诱导骨髓造血细胞衰老。

体内研究

在小鼠实验中,白消安治疗可显著增加细胞凋亡数量并导致睾丸重量下降。不同剂量(40毫克/千克至100毫克/千克)的Busulfan能够剂量依赖性地促进小鼠中的淋巴移植和同类系淋巴重组。

生产方法

白消安由甲基磺酰氯与1,4-丁二醇缩合而成。

  • Cobalamin conjugates for anti-tumor therapy

    The present invention provides a cobalamin-drug conjugate suitable for the treatment of tumor related diseases. Cobalamin is indirectly covalently bound to an anti-tumor drug via a cleavable linker and one or more optional spacers. Cobalamin is covalently bound to a first spacer or the cleavable linker via the 5′-OH of the cobalamin ribose ring. The drug is bound to a second spacer of the cleavable linker via an existing or added functional group on the drug. After administration, the conjugate forms a complex with transcobalamin (any of its isoforms). The complex then binds to a receptor on a cell membrane and is taken up into the cell. Once in the cell, an intracellular enzyme cleaves the conjugate thereby releasing the drug. Depending upon the structure of the conjugate, a particular class or type of intracellular enzyme affects the cleavage. Due to the high demand for cobalamin in growing cells, tumor cells typically take up a higher percentage of the conjugate than do normal non-growing cells. The conjugate of the invention advantageously provides a reduced systemic toxicity and enhanced efficacy as compared to a corresponding free drug.
    本发明提供了一种适用于治疗肿瘤相关疾病的钴胺素-药物结合物。钴胺素通过可切割的连接剂间接共价结合到抗肿瘤药物上,还可以通过一个或多个可选的间隔物。钴胺素通过其核糖环的5'-OH与第一间隔物或可切割连接剂共价结合。药物通过其现有或添加的功能基团与可切割连接剂的第二间隔物结合。在给药后,结合物与转钴胺素(其任何同工异构体)形成复合物。然后,该复合物结合到细胞膜上的受体并被细胞摄取。一旦进入细胞,细胞内酶将切割结合物,从而释放药物。根据结合物的结构,特定类别或类型的细胞内酶影响切割。由于生长细胞对钴胺素的需求量较高,肿瘤细胞通常摄取结合物的比例高于正常非生长细胞。本发明的结合物与相应的游离药物相比,具有较低的全身毒性和增强的疗效。
