  甲磺酸卡索吡坦的生产过程中的脱氟类似物的控制策略的发展。

  摘要：

  葛兰素史克（GlaxoSmithKline）将甲磺酸卡西波坦鉴定为对中枢神经系统（CNS）具有活性的药物的一部分。在开发制造过程的后期开发研究中，发现了新的杂质。详细讨论了这种合成杂质（一种原料药的脱氟类似物），以显示进行的工艺开发研究，以确保按照设计质量原则对最终原料药进行质量控制。通过对过程的了解以及风险分析，可以制定控制策略以提高质量保证水平。该控制策略允许将对杂质的控制移至起点，而不是在原料药中进行测试。

  摘要：

  A large body of compelling preclinical evidence supports the clinical use of neurokinin (NK) receptor antagonists in a plethora of CNS and non-CNS therapeutic areas. The significant investment made in this area over the past 2 decades culminated with the observation that NK1 receptor antagonists elicited clinical efficacy in major depression disorders. In addition, aprepitant (Merck) was launched as a new drug able to prevent chemotherapy-induced nausea and vomiting (CINV). After the discovery by GlaxoSmithKline of vestipitant, a wide drug discovery program was launched aimed at identifying additional clinical candidates. New compounds were designed to maximize affinity at the NK1 receptor binding site while retaining suitable physicochemical characteristics to ensure excellent pharmacokinetic and pharmacodynamic properties in vivo. Herein we describe the discovery process of a new NK1 receptor antagonist (casopitant) selected as clinical candidate and progressed into clinical studies to treat major depression disorders.
