unknown. The first synthesis of aulosirazole uses a route centered upon a late‐stage regioselective Diels–Alder reaction. The structurally related natural product pronqodine A, an inhibitor of prostaglandin release, and analogues thereof, were also prepared for comparison. Biological evaluation of the compounds identified one potential target as the immunoregulatory enzyme indoleamine‐2,3‐dioxygenase
通常与细胞氧化过程有关的天然醌具有明显的生物活性。特别是,从蓝绿色藻类中分离出的结构独特的异噻唑酮甲萘醌aulosirazole具有选择性的抗肿瘤细胞毒性作用,尽管其作用机理尚不清楚。aulosirazole的第一个合成方法以后期区域选择性Diels-Alder反应为中心。还制备了结构相关的天然产物前列腺素A(前列腺素释放的抑制剂)及其类似物用于比较。这些化合物的生物学评估确定了一个潜在的靶标,即免疫调节酶吲哚胺-2,3-双加氧酶(IDO)。异噻唑啉醌也是人醌还原酶NQO1的有效底物,
