  Nobiletin代谢产物：合成和对基质金属蛋白酶9产生的抑制活性

  摘要：

  通过高度氧化的苯乙酮衍生物开发了nobiletin代谢产物的多样化合成。我们使用市售的3,4,5-三甲氧基苯甲酸甲酯作为起始原料，以简化关键中间体2'-羟基-3'，4'，5'，6'-四甲氧基苯乙酮（I）的制备。这些代谢物显示出对人晶状体上皮细胞中基质金属蛋白酶9产生的强抑制活性。

  Concise synthesis of polymethoxyflavone sudachitin and its derivatives, and biological evaluations

  摘要：

  We accomplished a divergent synthesis of sudachitin (2), a polymethoxyflavone isolated from citrus fruits, and six derivatives from acetophenone 9, which was an intermediate in our previous synthesis of nobiletin (1). Compound 2 enhanced glucose-induced insulin secretion in INS-1D cells, but was less potent than 1. Compared with 1, compound 2 and two derivatives were more potent inhibitors of cAMP-specific phosphodiesterase. (C) 2018 Published by Elsevier Ltd.

  A divergent synthesis of nobiletin metabolites was developed through highly oxygenated acetophenone derivative. We used commercially available methyl 3,4,5-trimethoxybenzoate as a starting material for concise preparation of the key intermediate, 2′-hydroxy-3′,4′,5′,6′-tetramethoxyacetophenone (I). These metabolites showed strong inhibitory activity against matrix metalloproteinase-9 production in

  Fifteen polymethoxyflavones (PMFs) and hydroxylated PMFs were isolated from sweet orange (Citrus sinensis) peel extract and synthesized to investigate their biological activity. All obtained compounds were tested in HL-60 cancer cell proliferation and apoptosis induction assays. While some PMFs and hydroxylated PMFs had moderate anti-carcinogenic activities, 5-hydroxy-6,7,8,3',4'-pentamethoxyflavone and 5-hydroxy- 3,6,7,8,3',4'-hexamethoxyflavone showed strong inhibitory activities against the proliferation and induced apoptosis of HL-60 cell lines.
