A synthetic method to obtain α- and β-pyran naphthoquinones 10 and 11 with a hydroxyl substituent on the aromatic ring was developed. Two series of α- and β-pyran naphthoquinones were obtained from the 8-hydroxy-lawsone, and their anticancer properties were evaluated against four tumor cell lines. In general, the new compounds displayed good activity, possibly indicating that these compounds have increased pro-oxidant capacity. The 9-hydroxy-α-lapachone and 7-hydroxy-β-lapachone analogues of the natural products α-lapachone and β-lapachone were successfully produced by this methodology.
研究人员开发了一种合成方法,以获得芳香环上具有羟基取代基的δ-和δ-吡喃萘醌10和11。从 8-hydroxy-lawsone 中得到了两个系列的 α- 和 β-pyran 萘醌,并评估了它们对四种肿瘤细胞系的抗癌特性。总的来说,新化合物显示出良好的活性,这可能表明这些化合物具有更强的抗氧化能力。用这种方法成功地制备了天然产物δ-拉帕醌和δ-拉帕醌的9-羟基-δ-拉帕醌和7-羟基-δ-拉帕醌类似物。
