The myeloperoxidase (MPO) inhibitors 1 and 2 were prepared as their isotopologues with carbon-14, carbon-13, and nitrogen-15 or tritium with high specific activity and purity. Starting from potassium [14C]cyanide or [14C]formate provided metabolically stable 14C-labels on [14C]-1 and [14C]-2. Catalytic hydrogenation was used for the preparation of [3H]-2, giving multiple enriched positions as shown by 3H NMR. 1 and 2 are promising in vitro and in vivo imaging radioligands and have the potential to provide key information with regard to MPO expression, function, stoichiometry, and pharmacology.
髓过氧化物酶(MPO)抑制剂1和2被制备为其同位素变体,含有高比活性和纯度的碳-14、碳-13和氮-15或氚。以氰化钾[14C]或[14C]甲酸为起始物,提供了代谢稳定的14C标记在[14C]-1和[14C]-2上。采用催化加氢法制备[3H]-2,三氚核磁共振显示了多个富集位点。1和2在体外和体内成像放射配体中具有良好的前景,并有潜力提供关于MPO表达、功能、计量比和药理学的关键信息。
