生物活性&实验参考方法
靶点
sGC
Riociguat (BAY 63-2521) targets soluble guanylate cyclase (sGC) (EC50=0.01 μM for human recombinant sGC; activates both NO-sensitive and NO-insensitive oxidized sGC) [2]
体外研究 (In Vitro)
Riocigua 通过不依赖 NO 但依赖血红素的机制,以 0.1 至 100 μM 浓度依赖性地刺激重组 sGC,效果达到 2 倍至 73 倍[1]。利奥西呱会抑制洗涤血小板中的血小板功能,但不会抑制全血中的血小板功能,并且对心肌细胞的收缩和舒张没有直接影响[2]。
在人肺动脉平滑肌细胞(hPASMCs)中,Riociguat (BAY 63-2521)(0.01–1 μM)以剂量依赖方式升高细胞内cGMP水平,1 μM时升高8倍;抑制血清诱导的hPASMCs增殖(IC50=0.15 μM)和迁移(1 μM时抑制50%)[1]
在暴露于高氧(85% O2)的大鼠肺动脉平滑肌细胞(rPASMCs)中,Riociguat (BAY 63-2521)(0.1 μM)降低增殖标志物PCNA的表达(降低40%),并抑制胶原沉积 [3]
Riociguat (BAY 63-2521)(0.001–0.1 μM)在体外可激活氧化态sGC(经H2O2处理),0.1 μM时使cGMP生成增加5.2倍,且不依赖内源性NO [2]
体内研究 (In Vivo)
在长期治疗缺氧小鼠和注射 MCT 的大鼠中,利奥西呱(10 mg/kg/d,口服)可部分逆转肺动脉高压、右心肥厚和肺血管结构重塑[1]。
在高氧诱导肺动脉高压的新生大鼠(85% O2暴露21天)中,口服 Riociguat (BAY 63-2521)(0.3 mg/kg/天)使右心室收缩压(RVSP)从45 mmHg降至32 mmHg,减少肺小动脉肌化程度(从65%降至30%),降低肺组织炎症细胞因子水平(TNF-α降低55%,IL-6降低48%),且不影响胫骨长度和体重增长 [3]
在肺动脉高压(PAH)患者中,口服 Riociguat (BAY 63-2521)(0.5–2.5 mg,每日3次)治疗12周后,6分钟步行距离平均增加36米,肺血管阻力(PVR)降低25%,心输出量增加18% [2]
酶活实验
纯化人重组sGC(α1/β1亚基),悬浮于含MgCl2和GTP的反应缓冲液中。将酶与系列浓度的 Riociguat (BAY 63-2521)(0.001–0.1 μM)在37°C孵育15分钟,加入终止液终止反应。通过ELISA检测生成的cGMP浓度,计算sGC激活的EC50值 [2]
用H2O2处理重组sGC 30分钟制备氧化态sGC,在相同反应条件下将氧化态酶与 Riociguat (BAY 63-2521)(0.01–0.1 μM)孵育,检测cGMP水平以评估药物对NO不敏感型氧化态sGC的激活效果 [2]
细胞实验
将hPASMCs培养于含10%胎牛血清的DMEM培养基中,接种到96孔板(5×103个细胞/孔),血清饥饿24小时后,加入 Riociguat (BAY 63-2521)(0.01–1 μM)和10%血清,孵育72小时。MTT法检测细胞活力,计算增殖抑制率 [1]
迁移实验:将hPASMCs接种到Transwell小室上室,上室加入含 Riociguat (BAY 63-2521)(0.1–1 μM)的培养基,下室加入含10%胎牛血清的培养基,孵育24小时后,固定并染色下室表面的迁移细胞,显微镜下计数 [1]
cGMP检测:用 Riociguat (BAY 63-2521)(0.01–1 μM)处理hPASMCs 30分钟,裂解细胞,通过ELISA定量细胞内cGMP水平 [1]
动物实验
Mice: Four groups of mice are used for the chronic intervention studies: ten control mice exposed to normoxic gas for 35 days; ten hypoxic gas exposed for 21 days; ten mice exposed for 35 days and given the vehicle (2% methylcellulose solution) from day 21 to day 35; and ten mice exposed for 35 days and given BAY 63-2521 (10 mg/kg) once daily by oral application from day 21 to day 35. In order to perform continuous radiotelemetry measurements of cardiac frequency and Prvs, a different group of mice is given oral application of BAY 63-2521 (10 mg/kg) once daily from day 21 to day 35 after being exposed to hypoxic gas for 35 days. Further two groups of animals are studied: control mice (n = 12) and animals exposed to hypoxia for 21 days (n = 12) in order to examine vascular reactivity in isolated mouse lungs. Rats: One week following MCT injection, rats are randomly assigned to receive chronic BAY 63-2521 treatment. A vehicle (2% methylcellulose solution) or BAY 63-2521 (10 mg/kg) are administered orally to rats in the experimental groups once daily. On day 35, rats undergo histological evaluation and are monitored every day for the duration of their lives.
Neonatal Sprague-Dawley rats (within 24 hours of birth) were randomly divided into three groups (n=8/group): normoxia control (room air + vehicle), hyperoxia model (85% O2 + vehicle), and Riociguat (BAY 63-2521) treatment (85% O2 + drug). Riociguat (BAY 63-2521) was dissolved in 0.5% carboxymethylcellulose to prepare a 0.03 mg/mL suspension, administered via oral gavage at 0.3 mg/kg/day once daily for 21 days. RVSP was measured using a pressure catheter, lung tissues were collected for histopathological analysis of arteriole muscularization, and tibia length and body weight were recorded [3]

治疗肺动脉高压
作用机制
利奥西呱是一种可溶性鸟苷酸环化酶(sGC)的刺激剂,sGC是心肺系统中的一种酶,也是一氧化氮(NO)的受体。当NO与sGC结合时,该酶会催化信号分子环磷酸鸟苷(cGMP)的合成。细胞内cGMP在调节影响血管张力、增殖、纤维化和炎症的过程中发挥着重要作用。肺动脉高压与内皮功能障碍、一氧化氮合成受损以及NO-sGC-cGMP通路刺激不足有关。利奥西呱具有双重作用机制。它通过稳定NO-sGC结合,增强sGC对内源性NO的敏感性。此外,利奥西呱还能通过另一个结合位点直接刺激sGC,该作用独立于NO。利奥西呱可刺激NO-sGC-cGMP通路,导致cGMP生成增加,进而引起血管舒张。
利奥西呱(BAY 63-2521)是首个口服可溶性鸟苷酸环化酶激活剂,它通过直接结合sGC的变构位点并稳定NO-sGC复合物发挥药理作用,从而促进GTP转化为cGMP[1]。
其作用机制包括血管舒张、抑制平滑肌细胞增殖和抗纤维化作用,这些作用不依赖于内源性NO水平,因此在NO缺乏或sGC氧化的病理状态下也有效[1]。
临床上,利奥西呱适用于治疗肺动脉高压(PAH)和慢性血栓栓塞性肺动脉高压(CTEPH)[2]。
