  摘要：

  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。

  The available treatment for the prevention and cure of Chagas disease, caused by the protozoan Trypanosoma cruzi, is still unsatisfactory. Thus, there is an urgent need to develop new drugs. In the last few years, our research group has focused on finding a new chemical entity able to target the infectious bloodstream trypomastigotes. In this study, we assayed 16 β-lapachone analogous with modifications in the pyran and aromatic ring to find a new prototype with high trypanocidal activity. Interestingly, two ortho-naphthoquinones presented the best trypanocidal profile (8c and 8d with an IC50/24 h of 26.9 ± 1.3 and 23.5 ± 2.5 μM, respectively), which were 4 to 17 times more effective than β-lapachone (391.5 ± 16.5 μM) and the standard drug benznidazole (103.6 ± 0.6 μM). The introduction of a hydroxyl group on the compounds’ aromatic ring modulated their biological profile by increasing their activity not only for cancer cells (MDAMB435), as previously described in literature, but also against T. cruzi. The Structure-Activity Relationship (SAR) study indicated that this introduction modulated HOMO and MEP parameters, improving the trypanocidal activity.

  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.
