  Enzymatic Studies of Isoflavonoids as Selective and Potent Inhibitors of Human Leukocyte 5-Lipo-Oxygenase

  摘要：

  Continuing our search to find more potent and selective 5‐LOX inhibitors, we present now the enzymatic evaluation of seventeen isoflavones (IR) and nine isoflavans (HIR), and their in vitro and in cellulo potency against human leukocyte 5‐LOX. Of the 26 compounds tested, 10 isoflavones and 9 isoflavans possessed micromolar potency, but only three were selective against 5‐LOX (IR‐2, HIR‐303, and HIR‐309), with IC50 values at least 10 times lower than those of 12‐LOX, 15‐LOX‐1, and 15‐LOX‐2. Of these three, IR‐2 (6,7‐dihydroxy‐4‐methoxy‐isoflavone, known as texasin) was the most selective 5‐LOX inhibitor, with over 80‐fold potency difference compared with other isozymes; Steered Molecular Dynamics (SMD) studies supported these findings. The presence of the catechol group on ring A (6,7‐dihydroxy versus 7,8‐dihydroxy) correlated with their biological activity, but the reduction of ring C, converting the isoflavones to isoflavans, and the substituent positions on ring B did not affect their potency against 5‐LOX. Two of the most potent/selective inhibitors (HIR‐303 and HIR‐309) were reductive inhibitors and were potent against 5‐LOX in human whole blood, indicating that isoflavans can be potent and selective inhibitors against human leukocyte 5‐LOX in vitro and in cellulo.

• Synthesis of Various Kinds of Isoflavones, Isoflavanes, and Biphenyl-Ketones and Their 1,1-Diphenyl-2-picrylhydrazyl Radical-Scavenging Activities

  Forty-eight kinds of isoflavones (8), thirty-one isoflavanes (9), and forty-seven biphenyl-ketones (10, 10′) were synthesized from eleven kinds of substituted phenols (11) and six phenylacetic acids (12). Among them, seventy-five compounds are new. The radical scavenging activities of these compounds were evaluated using 1,1-diphenyl-2-picrylhydrazyl (DPPH) at pH 6.0. We found that thirty-nine out of forty-three compounds having a catechol moiety on either the A- or the B-ring exhibited a high activity (ED50=12—54 μM) similar to that of catechin. In these cases, the remaining part of their structure seemed to have little effect on their activity. Many 6- or 8-hydroxyisoflavanes (9E—I) and their biphenyl-ketone derivatives (10E—H) also showed a high activity (ED50=<50 μM), while all of their corresponding isoflavones (8E—I) were not active at all. The 7-hydroxyisoflavanes having either an additional hydroxyl group at the C5-position (9D) or a methoxy group at the C6-position (9J) presented a high activity (ED50=26—32 μM). This study suggests that natural isoflavones have the possibilities of exhibiting antioxidant activities through the hydroxylation at the C6-, C8-, or C3′-position or the formation of the isoflavanes (9) and/or the biphenyl-ketone derivatives (10′) by metabolism or biotransformation.

  合成了四十八种异黄酮（8）、三十一种异黄烷（9）以及四十七种联苯酮（10, 10′），这些化合物是由十一种取代酚（11）和六种苯乙酸（12）合成的。其中，有七十五种化合物是新发现的。这些化合物的自由基清除活性在pH 6.0下使用1,1-二苯基-2-吡唑啉酮（DPPH）进行了评估。我们发现，在四十三种含有儿茶酚基的化合物中，三十九种在A环或B环上表现出与儿茶素相似的高活性（ED50=12—54 μM）。在这些情况下，它们结构的其他部分似乎对活性影响不大。许多6-或8-羟基异黄烷（9E—I）及其联苯酮衍生物（10E—H）也显示出高活性（ED50=<50 μM），而它们对应的异黄酮（8E—I）则完全没有活性。具有在C5位增加羟基（9D）或在C6位增加甲氧基（9J）的7-羟基异黄烷则展现出高活性（ED50=26—32 μM）。本研究表明，天然异黄酮通过在C6、C8或C3′位置的羟基化，或通过代谢或生物转化形成异黄烷（9）和/或联苯酮衍生物（10′），具有表现抗氧化活性的可能性。
• Structure–activity relationship studies of flavonoids as potent inhibitors of human platelet 12-hLO, reticulocyte 15-hLO-1, and prostate epithelial 15-hLO-2

  Human lipoxygenase (hLO) isozymes have been implicated in a number of disease states and have attracted much attention with respect to their inhibition. One class of inhibitors, the flavonoids, have been shown to be potent lipoxygenase inhibitors but their study has been restricted to those compounds found in nature, which have limited structural variability. We have therefore carried out a comprehensive study to determine the structural requirements for flavonoid potency and selectivity against platelet 12-hLO, reticulocyte 15-hLO-1, and prostate epithelial 15-hLO-2. We conclude from this study that catechols are essential for high potency, that isoflavones and isoflavanones tend to select against 12-hLO, that isoflavans tend to select against 15-hLO-1, but few flavonoids target 15-hLO-2.

• Potential antioxidants and tyrosinase inhibitors from synthetic polyphenolic deoxybenzoins

  Deoxybenzoins (DOBs) are one-pot synthetic precursors of isoflavones with feature analogous to those beneficial polyphenols such as resveratrol (stilbene) and phloretin (dihydrochalcone). In this study, seventeen polyphenolic DOBs were synthesized and evaluated by various antioxidant assays and tyrosinase inhibitory effect in vitro. Results displayed that these DOBs are powerful antioxidants; for example, 2,3,4-trihydroxy-3',4'-dimethoxydeoxybenzoin possesses an excellent anti-lipid peroxidation activity (IC50 = 0.72 +/- 0.16 mu M), whilst 2,4,4',5-tetrahydroxydeoxybenzoin showed good DPPH radical scavenging activity (IC50 = 0.69 +/- 0.04 mu M), which were better than Trolox and vitamin C. Besides exhibiting a weak metal chelating effect, these DOBs were effective in scavenging ABTS(center dot+) and superoxide anion (O-2(center dot-)) radicals. DOBs also exhibited potent mushroom tyrosinase inhibitory activity; for example 2,3,4'-trihydroxy4- methoxydeoxybenzoin displayed stable and significant inhibitory effect on tyrosinase activity, with IC50 values 43.37, 43.10 and 46.10 mu M at incubation intervals of 0.5, 1.5, and 2.5 h, respectively. These results suggest that, with the advantage of being readily synthesizable small molecules, DOBs can be potentially developed into clinical and industrial antioxidants.
