The glitazone insulin sensitisers are an important class of pharmaceuticals for the treatment of Type 2 diabetes. Syntheses of [methyl-14C] and [3H]rosiglitazone maleate (BRL 49653-C), marketed by SmithKline Beecham Pharmaceuticals as Avandia® are described. [Methyl-14C]BRL 49653-C was prepared in 5 steps in 12.6% overall radiochemical yield from K[14C]CN. Catalytic reduction with tritium gas of a dibromo derivative gave [3H]rosiglitazone with a specific activity of 58Ci/mmol. Copyright © 2001 John Wiley & Sons, Ltd.
格列酮类胰岛素增敏剂是治疗2型糖尿病的一类重要药物。本文描述了由史克必成制药公司作为Avandia®销售的[甲基-14C]和[3H]罗格列酮马来酸盐(BRL 49653-C)的合成方法。[甲基-14C]BRL 49653-C通过5步反应,从K[14C]CN出发,总放射化学产率为12.6%。利用氚气对二溴衍生物进行催化还原,得到比活度为58Ci/mmol的[3H]罗格列酮。版权所有 © 2001 John Wiley & Sons, Ltd.
