respectively, from C-nucleosides 5-beta-d-ribofuranosylthiophene-3-carboxamide (thiophenfurin, 1), 5-beta-d-ribofuranosylfuran-3-carboxamide (furanfurin, 2), and 5-beta-d-ribofuranosylselenophene-3-carboxamide (selenophenfurin, 5), were synthesized as human inosine monophosphate dehydrogenase (IMPDH) type I and II inhibitors. The synthesis was carried out by imidazole-catalyzed coupling of the 5'-monophosphate
二核苷酸TFAD(6),FFAD(7)和SFAD(8),分别来自C-核苷5-β-d-核呋喃糖基噻吩-3-甲酰胺(thiophenfurin,1),5-beta-d的等排NAD类似物作为人肌苷单磷酸脱氢酶(IMPDH)的I型和II型抑制剂,合成了-呋喃呋喃糖基呋喃-3-羧酰胺(呋喃呋喃2)和5-β-d-呋喃核糖基硒吩3-羧酰胺(硒苯吩呋喃5)。合成是通过咪唑催化的1、2和5的5'-单磷酸酯与AMP偶联而进行的。这些二核苷酸也是噻唑-4-羧酰胺腺嘌呤二核苷酸(TAD)和硒唑-4-羧酰胺腺嘌呤二核苷酸(SAD)的类似物,它们是溶瘤性C-核苷2-β-D-核呋喃呋喃糖基噻唑-4-羧酰胺的活性代谢产物。 (tiazofurin)和2-beta-D-rifurfuranosylselenazole-4-carboxamide(selenazofurin),评估了它们对重组人IMPDH和I型II的抑制能力
