  Design and synthesis of selective CYP1B1 inhibitor via dearomatization of α-naphthoflavone

  摘要：

  Selective cytochrome P450 (CYP) 1B1 inhibition has potential as an anticancer strategy that is unrepresented in the current clinical arena. For development of a selective inhibitor, we focused on the complexity caused by sp(3)-hybridized carbons and synthesized a series of benzo[h] chromone derivatives linked to a non-aromatic B-ring using alpha-naphthoflavone (ANF) as the lead compound. Ring structure comparison suggested compound 37 as a suitable cyclohexyl-core with improved solubility. Structural evolution of 37 produced the azide-containing cis-49a, which had good properties in three important respects: (1) selectivity for CYP1B1 over CYP1A1 and CYP1A2 (120-times and 150-times, respectively), (2) greater inhibitory potency of > 2 times that of ANF, and (3) improved solubility. The corresponding aromatic B-ring compound 59a showed low selectivity and poor solubility. To elucidate the binding mode, we performed X-ray crystal structure analysis, which revealed the interaction mode and explained the subtype selectivity of cis-49a.

  Fungal metabolism of naphthoflavones

  摘要：

  Naphthoflavones (benzoflavones) are synthetic flavonoids commonly used in drug metabolism studies as selective activators or inhibitors of cytochrome P-450 enzymes. Nowadays they are also used as a component of food supplements for body builders. There is no data regarding naphthoflavone microbial metabolism. In the present studies sixty-three fungal strains have been screened for their ability to transform alpha-naphthoflavone (7,8-benzoflavone) or beta-naphthoflavone (5,6-benzoflavone). Five strains belonging to the genera Penicillium, Cladosporium, Aspergillus and Verticillium transformed alpha-naphthoflavone and beta-naphthoflavone to the corresponding 4'-hydroxy derivatives. These selected fungi have been used in a further study on biotransformation of naphthoflavones with a differently substituted B-ring. Only 4'-methoxy derivatives have been transformed to the related 4'-hydroxy products. Selected strains are good biocatalysts to obtain 4'-hydroxy naphthoflavones in the one step reaction.

  Cytochrome P450 enzymes protect the body from foreign substances through a mechanism that involves oxidation of those substances into more readily excretable polar compounds. It has been shown that some naphthoflavones function as substrates of certain P450 enzymes (CYP1A1 and CYP1B1) and with appropriate structural changes may become inhibitors. Moreover, propargyl ether derivatives of adamantane have been shown to function as selective inactivators of some P450 enzymes (CYP2B1 and CYP2B5). In an attempt to improve the potency and selectivity of inhibition, we have designed and synthesized a series of naphthoflavone propargyl ethers. We report here the synthesis, X-ray crystal structures, and inhibition data (IC50 of EROD inhibition in CYP1A1 and CYP1B1 enzymes) of α-naphthoflavone 2′-propargyl ether, β-naphthoflavone 2′-propargyl ether, α-naphthoflavone 4′-propargyl ether, and β-naphthoflavone 4′-propargyl ether.

  我们以前对黄酮类化合物和相关杂环的筛选具有激活囊性纤维化跨膜电导调节剂（CFTR）氯化物通道的能力，这表明UCCF-029是一种7,8-苯并黄酮，是一种有效的活化剂。在本研究中，我们描述了使用基于细胞的分析方法对一系列苯并黄酮类似物进行合成和评估，以检查其结构活性关系，并鉴定出对野生型CFTR和突变型CFTR（G551D -CFTR）在某些人类受试者中引起囊性纤维化。使用UCCF-029作为结构指导，制备了77种类黄酮类似物。对FRT细胞中面板的分析表明，黄酮A环在7,8位的苯环显着提高了化合物活性和几种类黄酮的效力。在3或4位上引入B环吡啶基氮也可提高CFTR活性，但这种结构修饰的影响不如苯甲环化均匀。最有效的新类似物UCCF-339以1.7 microM的K（d）激活了野生型CFTR，它比以前最有效的CFTR类黄酮活化剂芹菜素具有更高的活性。苯并黄酮类化合物中的几种化合物也可以活化G5
