Garcinoic acid has been identified as an inhibitor of DNA polymerase β (pol β). However, no structure-activity relationship (SAR) studies of garcinoic acid as a pol β inhibitor have been conducted, in part due to the lack of an efficient synthetic method for this natural product and its analogs. We developed an efficient semi-synthetic method for garcinoic acid and its analogs by starting from natural product δ-tocotrienol. Our preliminary SAR studies provided a valuable insight into future discovery of garcinoic acid-based pol β inhibitors.
garcinoic 酸已被鉴定为 DNA 聚合酶 β（pol β）的抑制剂。然而，garcinoic 酸作为 pol β 抑制剂的构效关系（SAR）研究尚未进行，部分原因是缺乏这种天然产物及其类似物的有效合成方法。我们从天然产物 δ-生育三烯醇开始，开发了 garcinoic 酸及其类似物的有效半合成方法。我们的初步 SAR 研究为未来发现基于 garcinoic 酸的 pol β 抑制剂提供了有价值的见解。
