  Synthesis and Biological Evaluation of Substituted Flavones as Gastroprotective Agents

  摘要：

  Flavone (1) was found to protect against ethanol-induced gastric damage in rats; however, it is known that certain compounds in the flavone class, including flavone itself, are inducers of hepatic drug metabolizing enzymes. With the hope of identifying gastroprotective flavones that have minimal effects on drug metabolizing enzymes, we have synthesized and evaluated selected flavone analogs. Gastroprotective potency in the ethanol model was retained by methoxy substitution in the 5-position (4) and by methoxy (12) or methyl (14) substitution in the 7-position. A number of substituted analogs of the potent molecule 5-methoxyflavone (4) were also synthesized, and in many cases, these substitutions provided gastroprotective molecules. In order to assess liver enzyme induction potential, two of the gastroprotective flavones, 7-methoxyflavone (12) and 5-methoxy-4'-fluoroflavone (26), were examined for their effect on liver microsomal cytochrome P450 and 7-ethoxyresorufin O-dealkylase (CYP1A) activity. These two compounds caused minimal changes in the cytochrome P450 concentration and were considerably less potent than beta-naphthoflavone as inducers of CYP1A enzyme activity. Furthermore, following oral administration to rats, 5-methoxy-4'-fluoroflavone (26) was found to protect against indomethacin-induced gastric damage. These results indicate that, through appropriate substitution, flavones can be obtained that are gastroprotective but have minimal effects on drug-metabolizing enzymes.

  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。

  A facile synthetic method has been developed for the conversion of methyl salicylate (5) into flavones 1a-i in high yields. Compound 5 on treatment with t-butyldimethylsilyl chloride (6) gave the O-silyl protected ester 7. Condensation of this ester 7 with the lithium anion generated from acetophenones 3a-i yielded the 1.3-diarylpropane-1,3-diones 8a-i, which on treatment with glacial acetic acid containing

  2'-, 3'-, and 4'-Methoxyflavones (MeFs) were incubated with nine forms of recombinant human cytochrome P450 (P450 or CYP) enzymes in the presence of an NADPH-generating system and the products formed were analyzed with LC-MS/MS methods.CYP1B1.1 and 1B1.3 were highly active in demethylating 4'MeF to form 4'-hydroxyflavone (rate of 5.0 nmol/min/nmol P450) and further to 3',4'-dihydroxyflavone (rates

  在产生NADPH的系统中，将2'-，3'-和4'-甲氧基黄酮（MeFs）与9种形式的重组人细胞色素P450（P450或CYP）酶一起孵育，并用LC- MS / MS方法.CYP1B1.1和1B1.3在4'MeF脱甲基形成4'-羟基黄酮（5.0 nmol / min / nmol P450的速率）和进一步生成3'，4'-二羟基黄酮（速率为5％的活性）方面具有很高的活性。分别为2.1和0.66 nmol / min / nmol P450）。发现3'MeF被P450氧化为m / z 239（M-14）产物（大概为3'-羟基黄酮），然后氧化为3'，4'-二羟基黄酮。P450还将2'MeF催化氧化为m / z 239（M-14）和m / z 255（M-14，M-14 + 16）产品，可能分别是单羟基和二羟基产品。将这些MeF与P450一起孵育时，至少形成了两种类型的具有m / z 269片段的环

  A domino reaction between 2‐hydroxy‐/2‐aminobenzaldehydes and α‐haloketones gives chromen‐4‐ones and quinolin‐4‐ones in good to excellent yields. This method represents a new extension of the Allan–Robinson and Friedländer reactions, and uses N‐heterocyclic‐carbene catalysis. This approach has the advantages of operational simplicity, ambient reaction conditions, and no by‐product formation.

  A series of nineteen 2-aryl-4H-chromen-4-one derivatives 2a-2s were synthesized and evaluated for their antiviral activity against Chikungunya virus (LR2006_OPY1) in Vero cell culture by CPE reduction assay. Three compounds 2a, 2b and 2g, were found to be active at concentration of (IC50) 0.44 M, 0.45 M and 2.02 M, respectively. Compounds having heterocyclic ring 2a and 2b at the 2nd position of the chromenone were found to be potent inhibitor of ChikV. Cytotoxicity studies were performed using Vero cell culture, compounds 2a and 2b exhibited SI of 100. Molecular docking simulation has been carried out to understand the possible mechanism of action.
