  Discovery and synthesis of novel luteolin derivatives as DAT agonists

  摘要：

  Luteolin, 5,7-dihydroxy-2-(3,4-dihydroxyphenyl)-4H-chromen-4-one, has been proposed and proved to be a novel dopamine transporter (DAT) activator. In order to develop this potential of luteolin, a series of novel luteolin derivatives were designed, synthesized, and evaluated for their DAT agonistic activities, utilizing constructed Chinese hamster ovary (CHO) cell lines stably expressing rat DAT. Biological screening results demonstrated that luteolin derivatives 1d, 1e, and 4c carry great DAT agonistic potency (EC(50) = 0.046, 0.869, and 1.375 mu M, respectively) compared with luteolin 8 (EC(50) = 1.45 +/- 0.29 mu M). Luteolin derivative 1d, notably, exhibited a 32-fold-higher DAT agonistic potency than luteolin. These luteolin derivatives represent a novel DAT agonist class, from which lead compounds useful for exploration of additional novel DAT agonists could be drawn. (C) 2010 Elsevier Ltd.

  In an effort to identify novel anti-inflammatory compounds, a series of flavone derivatives were synthesized and biologically evaluated for their inhibitory effects on the production of nitric oxide (NO) and prostaglandin E2 (PGE2), representative pro-inflammatory mediators, in LPS-induced RAW 264.7 cells. Their structure-activity relationship was also investigated. In particular, we found that compound

  为了鉴定新型抗炎化合物，合成了一系列黄酮衍生物，并对其在LPS-中对代表性的促炎性介质一氧化氮（NO）和前列腺素E2（PGE2）产生的抑制作用进行了生物学评估。诱导的RAW 264.7细胞。还研究了它们的构效关系。尤其是，我们发现与木犀草素（一种被称为强效抗炎剂的天然黄酮）相比，化合物3g对PGE2的产生显示出更强的抑制活性，对NO生成具有类似的抑制活性，并且细胞毒性也较弱。

Only in the case of 5,7,3′,4′,5′-pentamethoxyflavone, the strains were able to attach a sugar molecule in place of the methoxy substituent to give 3′-O-β-d-(4″-O-methylglucopyranosyl)-5,7,4′,5′-tetramethoxyflavone. However, we observed the tested strains’ ability to selectively demethylate/hydroxylate the carbon C-3′ and C-4′ of ring B of the substrates used. The structures of four hydroxyl-derivatives

  5,7-二甲氧基黄酮（一种菊花蛋白衍生物）存在于许多植物中，即使在高剂量下也显示出非常低的毒性。基于此现象，我们对通过化学合成获得的一系列菊花，芹菜素和甘油三酸酯的甲氧基衍生物进行了生物转化。我们使用了具有致病性的真菌菌株，证实了它们具有同时黄酮类化合物的羟化/去甲基化和糖基化的能力。甲氧基的数量和连接位置都影响生物转化率和产物的新生量。根据产品和半产品结构，可以得出结论，它们是级联转换的结果。仅在5,7,3'，4'，5'-五甲氧基黄酮的情况下，菌株能够连接糖分子代替甲氧基取代基以产生3'- O-β- d-（4″ -O-甲基吡喃葡萄糖基）-5,7,4'，5'-四甲氧基黄酮。但是，我们观察到了所测试菌株对所用底物B环的碳C-3'和C-4'进行选择性去甲基化/羟化的能力。确定了四种羟基衍生物的结构：4'-羟基-5,7-二甲氧基黄酮，3'-羟基-5,7-二甲氧基黄酮，3'-羟基-5,7,4'，5'-四甲氧基黄酮和5
