Puerarin 1 (8-β-D-Glucopyranosyl-4′-7-dihydroxyisoflavone, NPI-031G) is the major isoflavone C-glycoside isolated from Pueraria lobata, a traditional Chinese medicine widely used for the treatment of alcohol intoxication. In order to understand the mode of action of puerarin in the reward pathway of the central nervous system and to study its bioavailability and pharmacokinetics, we developed a synthetic route for the preparation of tritium-labeled puerarin. The key intermediate 4 was obtained by trimethylsilyl protection of all hydroxyl groups followed by selective deprotection. The corresponding aldehyde 5 was obtained through the subsequent oxidation of the primary alcohol. Standard NaB[3H]4 reduction and hydrolysis produced the tritium-labeled puerarin 6.

葛根素1(8-β-D-吡喃葡糖基-4′-7-二羟基异黄酮,NPI-031G)是葛藤中分离出的主要异黄酮C-糖苷,葛藤是一种传统中药,广泛用于治疗酒精中毒。为了解葛根素在大脑奖赏通路中的作用机制并研究其生物利用度和药代动力学,我们开发了一条合成氚标记葛根素的合成路线。关键中间体4通过将所有羟基进行三甲基硅基保护,随后进行选择性脱保护得到。通过接下来的伯醇氧化得到相应的醛5。标准NaB[3H]4还原和水解得到氚标记葛根素6。版权所有 © 2007 John Wiley & Sons, Ltd.
