  potential of synthetic isoflavones for application in cosmeceuticals. Twenty‐five isoflavones were synthesized and their capacities of free‐radical‐scavenging and mushroom tyrosinase inhibition, as well as their impact on cell viability of B16F10 murine melanoma cells and HaCaT human keratinocytes were evaluated. Isoflavones that showed significant mushroom tyrosinase inhibitory activities were further

  在这项研究中，我们研究了合成异黄酮在药妆品中的应用潜力。合成了 25 种异黄酮，并评估了它们清除自由基和抑制蘑菇酪氨酸酶的能力，以及它们对 B16F10 鼠黑色素瘤细胞和 HaCaT 人角质形成细胞的细胞活力的影响。进一步研究了显示出显着蘑菇酪氨酸酶抑制活性的异黄酮在体外 B16F10 黑素细胞中减少细胞黑色素形成和抗酪氨酸酶活性。在测试的异黄酮中，6-羟基黄豆苷元 (2) 是 ABTS.+ 和 DPPH 的最强清除剂。SC50 值分别为 11.3±0.3 和 9.4±0.1 μM 的自由基。Texasin (20) 表现出最有效的蘑菇酪氨酸酶抑制作用 (IC50 14.9±4.5 μM)，而 retusin (17) 分别显示出对 B16F10 黑素细胞中细胞黑色素形成和抗酪氨酸酶活性的最有效抑制。总之，retusin (17) 和 texasin (20) 都表现出强大的自由基清除能力

  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。
• 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.

  Deoxybenzoins are potent antioxidants and tyrosinase inhibitors with potential to be developed as food preservatives and cosmetic ingredients. To explore the potential in cardiovascular protection, 25 polyphenolic deoxybenzoins were synthesized and evaluated for inhibitory effects on KCl-induced porcine coronary arterial contraction. The results revealed deoxybenzoins are significant inhibitors of KCl-induced arterial contraction. Among those synthesized, two-thirds of the deoxybenzoins exhibited moderate to good efficacy on relaxing contracted artery including 2,4-dihydroxydeoxybenzoin with EC(50) = 3.30 mu M (E(max) = 100%, n = 7) and 2,4-dihydroxy-4'-methoxydeoxybenzoin EC(50) = 3.70 mu M (E(max) = 100%, n = 5). Deoxybenzoins displayed an endothelium-dependent relaxing manner on the contracted artery; the contractile responses of neither endothelium denuded nor L-NAME deactivated rings were inhibited. The structure activity relationships of deoxybenzoin on arterial relaxing effects concluded that the 2,4-dihydroxylated deoxybenzoins presented a potential vascular relaxing pharmacophore, with favoring substitution on ring B in the order of H >= p-OMe > p-OH > o-OMe > m,p-diOMe >= m-OMe.
