A new NADH-fumarate reductase inhibitor, verticipyrone, was isolated from the cultured broth of a fungus, Verticillium sp. FKI-1083. The structure was established as (E)-2-methoxy-3,5-dimethyl-6-(3-methyl-2-undecenyl)-4H-pyran-4-one. Verticipyrone exhibited an IC50 value of 0.88 nM against NADH-fumarate reductase of Ascaris suum. Verticipyrone inhibited both Ascaris and bovine heart complex I, and its synthetic analogue, 8,9-dihydro-8-hydroxyverticipyrone, showed good selectivity against Ascaris complex I.
一种新的烟酰胺腺嘌呤二核苷酸（NADH）-延胡索酸还原酶抑制剂——轮枝孢吡喃酮，是从真菌轮枝菌属FKI-1083的培养液中分离得到的。其结构确定为（E）-2-甲氧基-3,5-二甲基-6-（3-甲基-2-十一碳烯基）-4H-吡喃-4-酮。轮枝孢吡喃酮对猪蛔虫NADH-延胡索酸还原酶的半数抑制浓度（IC50）值为0.88纳摩尔。轮枝孢吡喃酮可抑制猪蛔虫和牛心脏的复合体I，其合成类似物8,9-二氢-8-羟基轮枝孢吡喃酮对猪蛔虫复合体I表现出良好的选择性。
