Oral calcitonin gene-related peptide (CGRP) receptor antagonists have been shown to be effective in the acute and preventive treatment of migraine. CGRP receptor antagonists offer safety advantages over triptans because they are not active vasoconstrictors, which reduces cardiovascular risks. Bristol Myers Squibb discovered a high affinity CGRP receptor antagonist BMS-927711 for the treatment of migraine now FDA approved as Nurtec® ODT (rimegepant). Dual-labeled [14C]-BMS-927711 was prepared and used in a human absorption–distribution–metabolism–elimination (ADME) study. A dual-labeled analog of BMS-927711 was required to fully track the compound's metabolic transformation. The carbon-14-labeled synthesis of both right side and left side portions of [14C]-BMS-927711 is described.

降钙素基因相关肽(CGRP)受体拮抗剂已被证明在偏头痛的急性和预防治疗中有效。与三
氟氯噻嗪(triptans)相比,CGRP受体拮抗剂具有安全性优势,因为它们不是活跃的血管收缩剂,从而减少心血管风险。百时美施贵宝发现了一种高亲和力的CGRP受体拮抗剂BMS-927711,现已获得FDA批准,用于治疗偏头痛,品牌名称为Nurtec® ODT(rimegepant)。制备了双标记的[14C]-BMS-927711,并在人体吸收-分布-代谢-排泄(A
DME)研究中使用。为了全面追踪该化合物的代谢转化,需制备BMS-927711的双标记类似物。本文描述了[14C]-BMS-927711的右侧和左侧部分的碳-14标记合成过程。
