代谢
Delamanid主要通过白蛋白代谢,其次在较小程度上由CYP3A4代谢。Delamanid的代谢也可能由肝脏的CYP1A1、CYP2D6和较小程度上的CYP2E1介导。在接受Delamanid治疗的患者血浆中已鉴定出四种主要代谢物(M1-M4),其中M1和M3占人体总血浆暴露的13%-18%。尽管它们没有保留显著药理活性,但它们仍可能对QT间期延长有所贡献。这对于Delamanid的主要代谢物M1(DM-6705)尤其如此。Delamanid主要通过血清白蛋白通过6-硝基-2,3-二氢咪唑[2,1-b]恶唑部分的羟基裂解形成M1(DM-6705)。这种主要代谢物的形成被认为是Delamanid代谢途径的关键起点。M1(DM-6705)可以通过三条途径进一步催化。在第一条代谢途径中,DM-6705经历恶唑部分的羟基化形成M2((4RS,5S)-DM-6720),随后通过CYP3A4介导的羟基氧化和恶唑到亚胺酮代谢物的互变异构化形成M3((S)-DM-6718)。第二条代谢途径涉及恶唑胺的水解和脱氨形成M4(DM-6704),然后羟基化形成M6((4R,5S)-DM-6721)和M7((4S,5S)-DM-6722)以及恶唑的氧化形成另一种酮代谢物M8((S)-DM-6717)。第三条途径涉及恶唑环的水解裂解形成M5(DM-6706)。
Delamanid predominantly undergoes metabolism by albumin and to a lesser extent, CYP3A4.. The metabolism of delamanid may also be mediated by hepatic CYP1A1, CYP2D6, and CYP2E1 to a lesser extent [31966]. Four major metabolites (M1–M4) have been identified in plasma in patients receiving delamanid where M1 and M3 accounts for 13%–18% of the total plasma exposure in humans. While they do not retain significant pharmacological activity, they may still contribute to QT prolongation. This is especially true for the main metabolite of delamanid, M1 (DM-6705). Delamanid is predominantly metabolized by serum albumin to form M1 (DM-6705) via hydrolytic cleavage of the 6-nitro-2,3-dihydroimidazo[2,1-b] oxazole moiety. The formation of this major metabolite is suggested to be a crucial starting point in the metabolic pathway of delamanid. M1 (DM-6705) can be further catalyzed by three pathways. In the first metabolic pathway, DM-6705 undergoes hydroxylation of the oxazole moiety to form M2 ((4RS,5S)-DM-6720), followed by CYP3A4-mediated oxidation of hydroxyl group and tautomerization of oxazole to an imino-ketone metabolite, M3 ((S)-DM-6718). The second metabolic pathway involves the hydrolysis and deamination of the oxazole amine to form M4 (DM-6704) followed by hydroxylation to M6 ((4R,5S)-DM-6721) and M7 ((4S,5S)-DM-6722) and oxidation of oxazole to another ketone metabolite, M8 ((S)-DM-6717). The third pathway involves the hydrolytic cleavage of the oxazole ring to form M5 (DM-6706).

吸收、分配和排泄
  • 吸收
在单次口服100毫克delamanid后,血药峰浓度达到135 ng/mL。稳态浓度在10-14天后达到。Delamanid的血药暴露量随着剂量的增加而增加,但增幅小于剂量比例。在动物模型(狗、大鼠、小鼠)中,delamanid的口服生物利用度报告为35%-60%。人类的绝对口服生物利用度估计在25%到47%之间。与空腹状态相比,与标准餐一起服用时,delamanid在人体中的口服生物利用度提高了约2.7倍,因为delamanid的水溶性较差。
Following a single oral dose administration of 100 mg delamanid, the peak plasma concentration was 135 ng/mL. Steady-state concentration is reached after 10-14 days. Delamanid plasma exposure increases less than proportionally with increasing dose. In animal models (dog, rat, mouse), the oral bioavailability of delamanid was reported to be 35%–60%. The absolute oral bioavailability in humans is estimated to range from 25 to 47%. Oral bioavailability in humans is enhanced when administered with a standard meal, by about 2.7 fold compared to fasting conditions because delamanid exhibits poor water solubility.

制备方法与用途

生物活性

Delamanid(OPC-67683)是一种新型的抗肺结核药物,具有良好的胞内杀菌活性,在细胞中能够高效积累。

体外研究

Delamanid 能抑制黏液酸的合成,这是结核分枝杆菌复合群细胞壁的关键组分。与敏感株和耐药株相比,Delamanid 对结核分枝杆菌表现出更强的抗菌活性。值得注意的是,Delamanid 不影响利福平、吡嗪酰胺及异烟肼的暴露;同时,当与Delamanid 共同给药时,乙胺丁醇的血药浓度-时间曲线下面积(AUCτ)和最大血药浓度(Cmax)均增加约25%。

体内研究

口服给予 Delamanid(剂量为30 mg/kg,连续给药5天),在实验性肺结核小鼠模型中可实现无菌治愈。

    摘要:
    德拉马尼是一种新型抗结核药物,在体外血浆白蛋白中被代谢为M1,这是一种通过切割6-硝基-2,3-二氢咪唑并[2,1-b]恶唑部分形成的独特代谢物。狗和人类的代谢活性高于啮齿动物。本研究对动物和人体内德拉马尼的药代动力学和代谢进行了特征分析。通过液相色谱-质谱分析,在反复口服给药后,在血浆中鉴定出由德拉马尼的咪唑并恶唑部分切割产生的八种代谢物(M1-M8)。德拉马尼最初被催化成M1,然后通过三条单独的途径进行代谢,这表明M1是一个关键的起始点。人类主要的代谢途径是对M1的恶唑部分进行羟化形成M2,然后主要由CYP3A4连续氧化成酮形式(M3)。在反复口服给药后,M1在八种代谢物中的暴露量最高,这表明M1是主要的代谢产物。德拉马尼的整体代谢在非临床物种和人类中在定性上相似,但在物种之间在定量上有所不同。反复给药后,狗和人体内的代谢物浓度远高于啮齿动物。白蛋白对德拉马尼的体外代谢活性可能是观察到的物种差异的原因。我们确定白蛋白代谢是德拉马尼药代动力学和代谢的关键组成部分。非肝脏形成M1和多条单独的代谢途径表明,德拉马尼和M1的临床显著药物-药物相互作用有限。

  • Pharmacokinetics and Metabolism of Delamanid, a Novel Anti-Tuberculosis Drug, in Animals and Humans: Importance of Albumin Metabolism In Vivo

    Delamanid, a new anti-tuberculosis drug, is metabolized to M1, a unique metabolite formed by cleavage of the 6-nitro-2,3-dihydroimidazo[2,1- b ] oxazole moiety, in plasma albumin in vitro. The metabolic activities in dogs and humans are higher than those in rodents. In this study, we characterized the pharmacokinetics and metabolism of delamanid in animals and humans. Eight metabolites (M1–M8) produced by cleavage of the imidazooxazole moiety of delamanid were identified in the plasma after repeated oral administration by liquid chromatography–mass spectrometry analysis. Delamanid was initially catalyzed to M1 and subsequently metabolized by three separate pathways, which suggested that M1 is a crucial starting point. The major pathway in humans was hydroxylation of the oxazole moiety of M1 to form M2 and then successive oxidation to the ketone form (M3) mainly by CYP3A4. M1 had the highest exposure among the eight metabolites after repeated oral dosing in humans, which indicated that M1 was the major metabolite. The overall metabolism of delamanid was qualitatively similar across nonclinical species and humans but was quantitatively different among the species. After repeated administration, the metabolites had much higher concentrations in dogs and humans than in rodents. The in vitro metabolic activity of albumin on delamanid probably caused the species differences observed. We determined that albumin metabolism is a key component of the pharmacokinetics and metabolism of delamanid. Nonhepatic formation of M1 and multiple separate pathways for metabolism of M1 suggest that clinically significant drug–drug interactions with delamanid and M1 are limited.
