The interruption of tyrosine kinase vascular endothelial growth factor receptor-2 (VEGFR-2) signaling by the binding of a small molecule inhibitor, for example, Brivanib, to VEGFR-2 kinase domain has been shown as an effective method of slowing angiogenesis and tumor progression. [14C]Brivanib, 13 and its prodrug [14C]Brivanib Alaninate, 15 were prepared to support preclinical and clinical studies. Their respective stable isotope-labeled versions, [13CN2]Brivanib, 21 and [13CN2]Brivanib Alaninate, 28, were also prepared to support bioanalytical LC-MS analyses of clinical samples. All of the four title compounds were synthetically derived from the respective isotopically labeled common pyrrolotriazinone intermediate, 6 or 16. This labeled central core pyrrolotriazinone was also conveniently used to synthesize other structurally related drug discovery candidates. Copyright © 2011 John wiley & Sons, Ltd.
酪氨酸激酶血管内皮生长因子受体-2(VEGFR-2)信号传导的中断,通过小分子抑制剂(例如Brivanib)与VEGFR-2激酶域的结合,已被证明是减缓血管生成和肿瘤进展的有效方法。[14C]Brivanib及其前药[14C]Brivanib Alaninate被制备以支持临床前和临床研究。它们各自的稳定同位素标记版本[13CN2]Brivanib和[13CN2]Brivanib Alaninate也被准备以支持临床样本的生物分析LC-MS分析。所有四种标题化合物都是从各自的同位素标记的常见吡咯三嗪酮中间体合成的。这个标记的中心核心吡咯三嗪酮也方便用于合成其他结构相关的药物发现候选物。版权 © 2011 John Wiley & Sons, Ltd.
