Product Introduction
Bioactivity
| 名称 | Zibotentan |
| 描述 | Zibotentan (ZD4054) (ZD4054) is a specific Endothelin (ET)A antagonist with IC50 of 21 nM, exhibiting no activity at ETB. Phase 3. |
| 细胞实验 | Cells are serum starved by incubation for 24 hours in serum-free DMEM before exposed to Zibotentan for 48 hours. After the treatment, cells are lysed and the supernatant is recovered and assayed for histone-associated DNA fragments, at 405 nm by the use of a microplate reader. For detection of early apoptotic events, floating and adherent cells are collected. Cells are double stained with FITC-conjugated Annexin V and propidium iodide using the Vybrant Apoptosis Kit and are immediately analyzed by cytofluorometric analysis.(Only for Reference) |
| 激酶实验 | Receptor-binding assays: The inhibition by Zibotentan (varying concentrations) of 125iodine-ET-1 binding to cloned human ETA is assessed using standard radioligand-binding techniques. Human recombinant ETA is expressed in mouse erythroleukaemic cells, and cell membranes prepared for competitive binding studies using 125iodine-ET-1 as the radioligand. Incubations are carried out in triplicate in the presence of Zibotentan, 100 pM to 100 μM in half-log increments, and inhibition of ET-1 binding is expressed as the geometric mean pIC50 value (concentration to inhibit 50% of binding) with a 95% confidence interval (CI). The affinity of Zibotentan for cloned human ETA is also assessed using the equation of Cheng and Prusoff to determine the equilibrium dissociation constant (Ki) in a further receptor-binding screen utilizing a greater number of concentration-response curves determined in three separate studies. |
| 体外活性 | Zibotentan专门抑制ETA介导的抗凋亡效应,而不影响ETB介导的促凋亡效应,在人类和大鼠的平滑肌细胞中,Zibotentan高亲和力地结合于内皮素A受体(ETA),Ki值为13 nM,对内皮素B受体(ETB)无亲和力,IC50值>10 μM。[1] 1 μM的Zibotentan处理抑制在分泌ET-1且表达ETA和ETB mRNA的卵巢癌细胞系HEY和OVCA 433中ET-1诱导的有丝分裂活性。[2] ZD4054(1 μM)抑制ET-1在HEY和OVCA 433细胞中诱导的EGFR转激活。Zibotentan(1 μM)通过增强E-钙黏蛋白表达和启动子活性,以及抑制血管内皮生长因子(VEGF)分泌和侵袭性,逆转ET-1介导的上皮-间质转换(EMT)。[3] Zibotentan还强效地抑制在SKOV-3和A-2780细胞中基础和ET-1诱导的细胞增殖,这与AKT和p42/44MAPK磷酸化的抑制、bcl-2的抑制和caspase-3及多聚(ADP-核糖)聚合酶蛋白的激活增加的凋亡有关。[4] |
| 体内活性 | 给予小鼠Zibotentan 10 mg/kg/日,连续21天的处理显著抑制HEY卵巢癌异种移植瘤的增长,抑制率达69%,且未观察到相关毒性。这与通过Ki-67表达的37%抑制评估的细胞增殖阻断,以及62%的肿瘤诱导血管生成抑制有关。一致地,Zibotentan处理显著抑制基质金属蛋白酶-2(MMP-2)和VEGF的表达,以及p42/44 MAPK和EGFR的激活,并强力增强E-cadherin的表达。[3] |

文献和实验网络 第十九章 杂环化合物和生物碱 杂环化合物在自然界分布很广,其数量几乎占已知有机化合物的三分之一,用途也很多。许多重要的物质如叶绿素、血红素、核酸以及临床应用的一些有显著疗效的天然药物和合成药物等,都含有杂环化合物的结构。生物碱多是中草药的有效成分,绝大多数是含氮的杂环化合物。本章内容与医学关系密切,具有重要意义。
分子中具有高能键的化合物。在生物体内主要有上式(Ⅰ)和(Ⅱ)两种结构的高能化合物。其作用为贮藏能量(例如 ATP、肌酸磷酸)和作为产生 ATP源的中间代谢产物(例如磷酸烯醇丙酮酸)以及合成反应的中间物质(例如酰基辅酶 A),在蛋白质的结构( conformation)变化周期的第一阶段上(例如钠钾 ATP酶的羧基磷酸中间体)也具有重要作用。多数高等化合物具有磷酸基,但也有例外。
由不同种元素组成的纯净物叫做化合物。化合物一般有固定的组成。化合物的组成一般可用化学式表示。化合物具有确定的物理性质和化学性质,不同于其组成元素的性质。化合物中的元素不能用简单的机械方法或物理方法分开,而必须用化学方法才能分离。
