Synthesis of novel inhibitors of human IMP dehydrogenase is described. These inhibitors are isosteric methylenebis(sulfonamide) analogues 5-8 of earlier reported mycophenolic adenine methylenebis(phosphonate)s 1-3. The parent bis(phosphonate) 1 and its bis(sulfonamide) analogue 5 showed similar sub-micromolar inhibitory activity against IMPDH2 (K(i) approximately 0.2 microM). However, the bis(sulfonamide)
描述了人IMP脱氢酶的新型抑制剂的合成。这些抑制剂是较早报道的霉菌酚腺嘌呤亚甲基双(膦酸酯)1-3的等规亚甲基双(磺酰胺)类似物5-8。母体双(膦酸酯)1及其双(磺酰胺)类似物5对IMPDH2具有类似的亚微摩尔抑制活性(K(i)约为0.2 microM)。但是,在腺嘌呤2位被取代的双(磺酰胺)类似物6和8的有效IMPPD2抑制剂(K(i)= 0.3-0.4 microM)比相应的母体双(膦酸酯)低约3至10倍。 s 2和3(K(i)= 0.04-0.11 microM)。
