代谢
肝脏。在人体中,去铁胺的CYP450催化(氧化)代谢似乎较少(约占8%)。葡萄糖苷酸化是去铁胺的主要代谢途径,随后通过胆汁排泄。
Hepatic. CYP450-catalyzed (oxidative) metabolism of deferasirox appears to be minor in humans (about 8%). Glucuronidation is the main metabolic pathway for deferasirox, with subsequent biliary excretion.

代谢
酸是一种用于治疗过载疾病(例如β-地中海贫血和输血引起的过载)的药物。它通过鳌合体内的来减少的积累,从而防止进一步的器官损伤。去酸的主要代谢途径是葡萄糖醛酸化,随后通过胆汁排出体外。在肠道中,葡萄糖醛酸化物可能会发生去结合,并随后被重新吸收(肠肝循环)。去酸主要由UGT1A1酶进行葡萄糖醛酸化,其次是由UGT1A3酶。CYP450酶催化的(氧化性)代谢在人类中似乎较少(大约8%)。
Glucuronidation is the main metabolic pathway for deferasirox, with subsequent biliary excretion. Deconjugation of glucuronidates in the intestine and subsequent reabsorption (enterohepatic recycling) is likely to occur. Deferasirox is mainly glucuronidated by UGT1A1 and to a lesser extent UGT1A3. CYP450-catalyzed (oxidative) metabolism of deferasirox appears to be minor in humans (about 8%).

代谢
肾脏排泄仅占剂量的8%,主要包括葡萄糖苷酸M6。细胞色素450酶的氧化代谢产生M1[5-羟基(OH)去铁胺,可能是通过CYP1A]和M4(5'-OH去铁胺,通过CYP2D6)的比例较小(分别占剂量的6%和2%)。直接和间接的证据表明,去铁胺的主要代谢途径是通过葡萄糖苷酸化生成代谢物M3(酰基葡萄糖苷酸)和M6(2-O-葡萄糖苷酸)。
... Renal excretion was only 8% of the dose and included mainly the glucuronide M6. Oxidative metabolism by cytochrome 450 enzymes to M1 [5-hydroxy (OH) deferasirox, presumably by CYP1A] and M4 (5'-OH deferasirox, by CYP2D6) was minor (6 and 2% of the dose, respectively). Direct and indirect evidence indicates that the main pathway of deferasirox metabolism is via glucuronidation to metabolites M3 (acyl glucuronide) and M6 (2-O-glucuronide).
来源:Hazardous Substances Data Bank (HSDB)
代谢
... deferasirox的代谢包括在羧酸基团(酰基葡萄糖苷酸M3)和羟基上的葡萄糖苷酸化,以及在一定程度上,细胞色素P450催化的羟基化。两种羟基代谢物(M1和M2)被给予大鼠,并显示在体内对的消除没有实质性贡献。
... Metabolism /of deferasirox/ included glucuronidation at the carboxylate group (acyl glucuronide M3) and at phenolic hydroxy groups, as well as, to a lower degree, cytochrome P450-catalyzed hydroxylations. Two hydroxylated metabolites (M1 and M2) were administered to rats and were shown not to contribute substantially to iron elimination in vivo.

毒理性
  • 肝毒性
在大规模的临床试验中,使用去铁胺的患者中,有6%的患者血清转平升高超过正常上限的5倍(ULN),其中1%到2%的患者因此停止了药物治疗。此外,还有几份单个病例报告显示,在去铁胺治疗期间出现了临床明显的肝损伤,这些损伤通常是严重的,偶尔是致命的。急性肝损伤的出现时间从开始使用去铁胺后的几天到几年不等,但大多数病例发生在1到3个月内。肝损伤的模式通常是肝细胞型或混合型,血清转平显著升高。免疫过敏和自身免疫特征缺失。一旦停止使用去铁胺,恢复通常很快,但有些病例与进行性肝损伤和肝衰竭有关。由于过载的患者通常有潜在的肝脏疾病,叠加的急性肝细胞损伤可能会导致急性肝衰竭的风险增加。去铁胺对肝毒性有黑框警告,并建议定期监测血清胆红素和转平。
In large clinical trials of deferasirox, elevations in serum aminotransferase levels above 5 times the upper limit of normal (ULN) occurred in 6% of patients and led to drug discontinuation in 1% to 2%. In addition, there have been several single case reports of clinically apparent liver injury arising during deferasirox therapy which was often severe and occasionally fatal. The onset of acute liver injury ranged from a few days to severak years after starting deferasirox but most cases occurred within 1 to 3 months. The pattern of liver injury was typically hepatocellular or mixed with prominent elevations in serum aminotransferase levels. Immunoallergic and autoimmune features were absent. Recovery was usually rapid once deferasirox was stopped, but some cases were associated with progressive liver injury and hepatic failure. Because patients with iron overload often have underlying liver disease, a superimposed acute hepatocellular injury may result in an increased risk of acute liver failure. Deferasirox has a boxed warning regarding hepatotoxicity and regular monitoring of serum bilirubin and aminotransferase levels is recommended.

Exjade 口服给药后吸收,达到最高血浆浓度(tmax)的中位数时间约为1.5-4小时。在单次给药和稳态条件下,去铁胺的Cmax和AUC随剂量增加而近似线性增加。多次给药后,去铁胺的暴露量增加了1.3-2.3倍的积累因子。去铁胺悬浮片的绝对生物利用度(AUC)为70%,与静脉给药相比。当与餐同服时,去铁胺生物利用度(AUC)会不同程度地增加。
Exjade is absorbed following oral administration with median times to maximum plasma concentration (tmax) of about 1.5-4 hours. The Cmax and AUC of deferasirox increase approximately linearly with dose after both single administration and under steady-state conditions. Exposure to deferasirox increased by an accumulation factor of 1.3-2.3 after multiple doses. The absolute bioavailability (AUC) of deferasirox tablets for oral suspension is 70% compared to an intravenous dose. The bioavailability (AUC) of deferasirox was variably increased when taken with a meal.

吸收、分配和排泄
当前研究评估了单次口服375毫克去铁酮片的绝对生物利用度,与静脉输注130毫克去铁酮进行比较。由于这是首次使用去铁酮静脉(IV)制剂的人体研究,因此在主要研究阶段之前,先在3名受试者中以较低剂量(65毫克)进行了预试验阶段,以评估静脉制剂的安全性及耐受性。主要研究阶段包括17名健康男性志愿者。在每次治疗后测量去铁酮的血浆浓度,并确定了包括绝对口服生物利用度在内的药代动力学参数。去铁酮片的绝对口服生物利用度为70%(90%置信区间,62%-80%)。去铁酮的特征是血浆清除率低,为3.53(+/- 0.87)L/小时。确定了去铁酮在稳态下的小体积分布(V(ss))为14.37(+/-2.69 L),表明组织分布低。
... The current study evaluated the absolute bioavailability of a single 375-mg oral dose of deferasirox administered in the form of tablets compared with a 130-mg intravenous infusion of deferasirox. Since this was a first-in-man study using the deferasirox intravenous (IV) formulation, the safety and tolerability of the IV formulation was evaluated in a pilot phase with a lower dose (65 mg) in 3 subjects prior to the main phase. The main study phase consisted of 17 healthy male volunteers. Plasma concentrations of deferasirox were measured following each treatment, and pharmacokinetic parameters including absolute oral bioavailability were determined. Absolute oral bioavailability of the deferasirox tablets was 70% (90% confidence interval, 62%-80%). Deferasirox was characterized as having a low plasma clearance of 3.53 (+/- 0.87) L/hr. A small volume of distribution of deferasirox at steady state (V(ss)) of 14.37 (+/-2.69 L) was determined, indicating a low tissue distribution.

    癌细胞的发展和恶性与表观基因组的变化密切相关。在这项工作中,线粒体靶向铼(I)复合物(DFX-e3中),整合临床铁螯合剂地拉罗司(DFX),已设计。通过将铁迁移到线粒体并改变与表观遗传修饰相关的关键代谢物种,DFX-Re3可以提高组蛋白,DNA和RNA的甲基化水平。因此,DFX‐Re3会影响与凋亡,RNA聚合酶和T细胞受体信号通路相关的事件。最后,显示DFX‐Re3诱导免疫原性凋亡细胞死亡并在体内表现出有效的抗肿瘤活性。这项研究为新型表观遗传药物的设计提供了一种新方法,该药物可以通过干预线粒体代谢和铁稳态来重新编码癌症表观基因组。
