产品描述
Macitentan(以前称为 ACT-064992;ACT064992;ACT 064992;Opsumit)是一种口服生物可利用的非肽 ETA/ETB 内皮素 (ET) 受体双重拮抗剂。它已被批准用于治疗肺动脉高压(PAH)。在中国仓鼠卵巢细胞中,它抑制 125I-ET-1 与重组 ETA 受体的结合,IC50 值为 0.5 ± 0.2 nM (n= 17)。
生物活性&实验参考方法
靶点
ET-A ( IC50 = 0.5 nM ); ET-B ( IC50 = 0.5 nM )
体外研究 (In Vitro)
体外活性:Macitentan 可完全抑制 ET-1 对原代人肺平滑肌细胞诱导的细胞内钙增加,IC50 约为 1 nM。 Macitentan 抑制 ET-1 诱导的离体大鼠主动脉环收缩或 S6c 诱导的离体大鼠气管环收缩,pA2 分别为 7.6 和 5.9。细胞测定:在过表达人 ETA 和 ETB 的中国仓鼠卵巢细胞的微粒体膜中,马西腾坦抑制 125I-ET-1 与重组 ETA 受体之间的结合,平均 IC50 值为 0.5 ± 0.2 nM (n= 17)。 ETB 受体的平均 IC50 值为 391±182 nM (n= 17)。马西腾坦完全抑制了ET-1增加非重组细胞内钙的作用。
体内研究 (In Vivo)
对血压正常的大鼠施用马西腾坦可增加血浆 ET-1 浓度,其剂量比波生坦低 10 倍。马西腾坦剂量依赖性地降低高血压 DOCA 盐大鼠的平均动脉血压,剂量为 10 mg/kg 时的最大效果为 -26 mm Hg,ED50 为 1mg/kg。在最大有效剂量下,马西腾坦的血压反应持续时间约为 40 小时。口服马西腾坦可剂量依赖性地预防肺动脉高压的发生和右心室肥大的发生,在野百合碱大鼠肺动脉高压模型中,最大疗效为 30 mg/kg/天。长期口服 30 mg/kg/天的马西替坦可显着改善野百合碱大鼠的 42 天生存率(马西替坦与载体相比,生存率分别为 83% 和 50%;42 天死亡率降低 66%)。在链脲佐菌素诱导的糖尿病大鼠模型中,马西腾坦(30 mg/kg/天)治疗 24 小时可部分阻止肾血管收缩的发生并增加肾血流量。马西腾坦可增加肾小球滤过率并降低滤过分数,并减轻血管和肾小管间质病变以及肾小球损伤。马西腾坦(25 mg/kg/天,口服)可减弱肾脏、心脏和视网膜 ET-1、TGF-β1、VEGF、FN、EDB+FN、胶原α-I(IV) mRNA 表达的增加以及 FN、胶原蛋白的增加db/db 小鼠中 2 型糖尿病诱导的蛋白质和 NF-κB 激活。马西腾坦还可以改善这些糖尿病小鼠的系膜扩张、心脏功能障碍以及 ANP 和 BNP 表达的增加。马西腾坦 (100mg/kg) 联合紫杉醇 (5 mg/kg) 治疗可降低肿瘤发生率(紫杉醇为 5/9 vs 紫杉醇 9/9)并进一步降低肿瘤重量(中位[范围]:0.1 g 与紫杉醇 0.4 g)与单独使用紫杉醇相比,SKOV3ip1 卵巢癌模型中腹水的发生率(紫杉醇为 0/9 vs 4/9)。马西腾坦联合紫杉醇通过降低 pVEGFR2、pAkt 和 pMAPK 的水平来抑制 ETR 的磷酸化并抑制肿瘤细胞的生存途径。马西腾坦增强紫杉醇对肿瘤细胞分裂(Brud+细胞:18.5 vs 紫杉醇 30.8)和细胞凋亡(TUNEL+细胞:195 vs 150 紫杉醇)的作用。
动物实验
The experiment uses male db/db mice and age- and sex-matched controls (27–32 g). Once diabetes onset occurs, randomly chosen diabetic animals are observed for two or four months. Macitentan oral treatment (25 mg/kg/day, food admix) is administered to groups of diabetic mice (n = 7/group) for the same duration. Body weight and blood glucose levels are measured to keep an eye on the animals.
药代性质 (ADME/PK)
Absorption, Distribution and Excretion
Macitentan has a median Tmax of 8h although some studies have found up to 30h at higher doses. Although the bioavailability has not been experimentally determined, pharmacokinetic modeling has estimated it at 74%. Food has not been found to have a significant effect on absorption.
Eliminated 50% through urine and 24% through feces. Of the 50% excreted through the urine, none of the recovered dose was in the form of the parent drug nor the active metabolite.
Macitentan has an apparent volume of distribution of 40-50L.
Clearance data was not found.
Metabolism / Metabolites
Macitentan undergoes oxidative depropylation of the sulfonamide moiety via CYP3A4, 2C8, 2C9, and 2C19 to form the active metabolite M6. The ethylene glycol moiety undergoes oxidative cleavage via CYP2C9 to the alcohol metabolite M4. M4 is oxidized to its corresponding acid, M5, then hydrolyzed to the metabolite termed m/z 324. Oxidative depropylation of a distal carbon atom via CYP2C8, 2C9, and 2C19 forms M7. Hydrolysis of both macitentan and M5 produces M3. Finally M5 may be further metabolized via hydrolysis and hydroxylation to M2 or via glucuronidation to a glucuronide metabolite, M1.
Biological Half-Life
The half-life of elimination of macitentan is 16 hours. The half-life of elimination of the active metabolite is 40-66h
毒性/毒理 (Toxicokinetics/TK)
Hepatotoxicity
Macitentan is associated with a low rate of serum aminotransferase elevations (0% to 4%) that, in clinical trials, was similar to the rate among placebo recipients. These elevations were usually mild, transient and not associated with symptoms, but were above 8 times the ULN in 2% of subjects (vs 0.4% of controls) in at least one long term study. For these reasons, the product label recommends that patients have serum enzymes tested before starting therapy and be alerted to the possibility and symptoms of liver injury during therapy. While there have been no published reports of clinically apparent liver injury with jaundice associated with macitentan, it has had limited general use. Other endothelin receptor antagonists (bosentan, sitaxentan) have been linked to several instances of acute liver injury, some of which have been severe. The onset of illness was usually within 1 to 6 months of starting bosentan and the enzyme pattern was typically hepatocellular or mixed. Immunoallergic features were not present and autoantibodies absent or present in low titer. Macitentan and ambrisentan have not been linked to similar cases.
Likelihood score: E* (unlikely but suspected cause of clinically apparent liver injury).
Protein Binding
Macitentan is >99% bound to plasma proteins, primarily to albumin and to a lesser extent α1-acid glycoprotein.
