Analysis Note
这些二级标准品可追溯至USP、EP和BP一级标准品。
Application
来曲唑可用作药物标准品,用于通过各种色谱技术测定生物/环境样品和药物制剂中的分析物。
这些二级标准品是合格的认证标准物质(CRM)。它们适用于多种分析应用,包括但不限于药物释放测试、药物的定性和定量分析方法开发、食品和饮料质量控制检测以及其他校准需求。
Biochem/physiol Actions
来曲唑是一种非甾体芳香酶抑制剂。
来曲唑是第三代非甾体芳香酶抑制剂。 它是芳香酶系统的竞争性抑制剂,因此可抑制雄激素向雌激素转化。来曲唑通过竞争性结合到该酶的细胞色素P450亚基的血红素上而抑制芳香酶,导致所有组织中雌激素的生物合成减少。
General description
用于质量控制的药物二级标准品,为制药实验室和制造商制备内部工作标准品提供了一种方便、高性价比的替代方案。
来曲唑用于治疗激素依赖性绝经后患者的乳腺癌。该药物通过阻断雌激素的合成而起作用,雌激素是癌症的病原体。
