  Insights into the In Vitro Antitumor Mechanism of Action of a New Pyranoxanthone

  摘要：

  Naturally occurring xanthones have been documented as having antitumor properties, with some of them presently undergoing clinical trials. In an attempt to improve the biological activities of dihydroxyxanthones, prenylation and other molecular modifications were performed. All the compounds reduced viable cell number in a leukemia cell line K‐562, with the fused xanthone 3,4‐dihydro‐12‐hydroxy‐2,2‐dimethyl‐2H,6H‐pyrano[3,2‐b]xanthen‐6‐one (5) being the most potent. The pyranoxanthone 5 was particularly effective in additional leukemia cell lines (HL‐60 and BV‐173). Furthermore, the pyranoxanthone 5 decreased cellular proliferation and induced an S‐phase cell cycle arrest. In vitro, the pyranoxanthone 5 increased the percentage of apoptotic cells which was confirmed by an appropriate response at the protein level (e.g., PARP cleavage). Using a computer screening strategy based on the structure of several anti‐ and pro‐apoptotic proteins, it was verified that the pyranoxanthone 5 may block the binding of anti‐apoptotic Bcl‐xL to pro‐apoptotic Bad and Bim. The structure‐based screening revealed the pyranoxanthone 5 as a new scaffold that may guide the design of small molecules with better affinity profile for Bcl‐xL.

  SAR analysis revealed that the anti-proliferative activity of the xanthones is substantially influenced by the position and number of attached hydroxyl and prenyl groups, and the presence of hydroxyl group ortho to the carbonyl function of xanthone scaffold contributes significantly to their cytotoxicity. The new prenylated xanthone 20 with a relatively simple structure, namely 1,3,8-trihydroxy-2-prenylxanthone

  为了探索围绕带有羟基和异戊二烯基部分的蒽酮骨架的详细结构-活性关系（SAR），已合成了29种天然和非天然羟基化和异戊烯化的氧杂蒽酮，并评估了它们对五种人的体外抗增殖活性癌细胞系，包括HepG2（肝细胞癌），HCT-116（结肠癌），A549（肺癌），BGC823（胃癌）和MDAMB-231（乳腺癌）。SAR分析表明，氧杂蒽酮的抗增殖活性受附着的羟基和异戊二烯基的位置和数量的影响很大，而与黄酮骨架的羰基功能邻位的羟基的存在显着影响了它们的细胞毒性。发现具有相对简单结构的新的异戊烯酮黄酮20，即1,3,8-三羟基-2-异戊二烯酮吨酮，对所有五个癌细胞系均表现出与α-Mangostin相当的有效抗肿瘤活性。进一步的机理研究表明，化合物20诱导HepG2细胞凋亡并导致细胞周期停滞在S期。这些结果突出了化合物20作为新型有效的广谱抗肿瘤药物未来开发的潜在新的潜在候选者。

  Inspired by the therapeutic potential of the simplified caged xanthones, we have developed a chemical strategy for synthesizing novel aza-caged Garcinia analogues through a regioselective Claisen/Diels–Alder cascade reaction. The origin of regioselectivity has been explained using the DFT method. We have further evaluated the cell proliferation and IKKβ inhibitory activities of these compounds and studied their binding mode with IKKβ by molecular docking. The results suggested that the aza-caged scaffold provides a suitable modification site and the introduction of a hydrophobic moiety leads to improvement in the cytotoxicity and IKKβ inhibitory activity. The aza-caged compound 6c exhibited an IC50 value of 2.68, 2.10, 8.02 μM against the HepG2, A549 cells and IKKβ, respectively. Mechanism studies with 6c showed that the aza-caged compounds induce apoptosis and cell cycle S phase arrest in A549 cells.
