[3H](4-Fluorobutyl)propyl[2,5,6-trimethyl-7-(2,4,6-trimethylphenyl)pyrrolo[2,3-d]pyrimidin-4-yl]amine ([3H]LWH-154), a novel potent radiolabelled analog of the nonpeptide corticotropin-releasing hormone type 1 receptor (CRHR1) selective antagonist, butylethyl[2,5,6-trimethyl-7-(2,4,6-trimethylphenyl)pyrrolo[2,3-d]pyrimidin-4-yl]amine (antalarmin), was prepared for the development of positron emission
[3H](4-氟丁基)丙基[2,5,6-三甲基-7-(2,4,6-三甲基苯基)吡咯并[2,3-d]嘧啶-4-基]胺([3H]LWH- 154),一种新型强效放射性标记非肽类促肾上腺皮质激素释放激素 1 型受体 (CRHR1) 选择性拮抗剂的类似物,丁基乙基[2,5,6-三甲基-7-(2,4,6-三甲基苯基)吡咯[2,3 -d]pyrimidin-4-yl]amine (antalarmin),用于开发 CRHR1 的正电子发射断层扫描放射性示踪剂,并评估作为非肽放射性配体用于药理学研究。前体(4-氟丁基)丙-2-烯基[2,5,6-三甲基-7-(2,4,6-三甲基苯基)吡咯并[2,3-d]嘧啶-4-基]胺(6)以 76% 的总产率从 3 分两步制备用于氚化。使用氚气和钯作为催化剂催化还原不饱和氟化物 6 得到 [3H]LWH-154。HPLC纯化后,获得高放射化学纯度的[3H]LWH-154,比活为69Ci/mmol。版权所有
