  Azachalcones 及其肟类对蘑菇酪氨酸酶的抑制动力学：一种简便的固态合成

  摘要：

  基于固态的机械化学过程用于合成新型氮杂查耳酮及其肟作为酪氨酸酶抑制剂。研究了它们以 l-3,4-二羟基苯丙氨酸为底物对蘑菇酪氨酸酶的抑制活性。合成的两种新型肟衍生物被认为比阳性对照曲酸更有效。化合物 1b 和 2b 均以剂量依赖性方式抑制酪氨酸酶的双酚酶活性，其 IC50 值分别为 15.3 和 12.7 μm。动力学分析表明它们的抑制机制是可逆的。两种新型肟化合物均显示出竞争性抑制，其 Ki 值分别为 5.1 和 2.5 μm。这种方法最大限度地减少了废物处理问题，并提供了一种简单、高效、

  lipophilic chalcones, in particular those with 4'-hydroxyl-substituted B rings and hetero/polyaromatic A rings. In contrast, chalcones with good antimalarial activity have alkoxylated B rings and electron-deficient A rings. Visualization of the steric and electrostatic fields generated from comparative molecular field analysis (CoMFA) indicate that the ring A of chalcones make a more significant contribution

  测试了一系列含氧查耳酮（已在早期评估了其抗疟活性）（恶性疟原虫K1）对利什曼原虫杜鹃花的抗疟原虫活性。构效关系的比较表明，这两种活动存在不同的理化和结构要求。抗利什曼活性与较少的亲脂性查耳酮有关，特别是具有4'-羟基取代的B环和杂/多芳族A环的亲脂查耳酮。相反，具有良好抗疟疾活性的查耳酮具有烷氧基化的B环和缺电子的A环。比较分子场分析（CoMFA）产生的空间和静电场的可视化表明，查耳酮的A环对抗疟药活性的贡献更大，而A环和B环均对抗疟疾活性很重要。尽管有不同的要求，但还是发现了两个烷氧基化的查耳酮（8、19），它们结合了良好的抗疟和抗疟疾活性。

  Notably, the introduction of three methoxy groups at positions 3, 4, 5 on ring B appears to be critical for cytotoxicity. The best compound, with potent and selective cytotoxicity (IC50 = 12.51 μM in comparison with the value 10.84 μM of paclitaxel), contains a phenothiazine moiety on ring A and a thiophene heterocycle on ring B. Most of the potential compounds only show weak cytoxicity on the noncancerous

  A series of synthetic chalcones, flavanones, and flavones has been synthesized and evaluated for antitumor activity against the human kidney carcinoma cells TK-10, human mammary adenocarcinoma cells MCF-7 (estrogen receptor-positive), and human colon adenocarcinoma cells HT-29. The most active series is the chalcone ones with the best results against TK-10 and HT-29 cells. Fourteen out of 53 analyzed compounds resulted very active against at least two of the studied tumoral cells. Alkaline single cell gel electrophoresis, comet assay, was performed as a study of the chromosomal aberrations promoted by the compounds on normal cells. Four active and two inactive chalcones were studied in the comet assay against normal human kidney cells (HK-2). A structure-activity relationship analysis of these compounds was performed and for 4- and 3,4-disubstituted derivatives a quantitative correlation was obtained in the case of anti-HT-29 activity.

• Identification of chalcones as in vivo liver monofunctional phase II enzymes inducers

  Cancer preventive agents (CPA) are drugs able to suppress the carcinogen metabolic activation or block the formation of ultimate carcinogens. CPA could act through various molecular mechanisms, for example by interfering with the action of procarcinogen. This could be attained by increasing the phase II enzymes levels of quinone reductase (QR) and glutathione S-transferase (GST). New flavonoids, especially chalcones, have been identified as in vivo monofunctional phase II enzymes inducers. Oral administration of chalcone, 4, and both p-methoxy-substituted chalcones, 6 and 14, increased hepatic QR activity with concomitant decrease in CYP1A1 activity, a member of the most important group of phase I enzymes cytochrome P450. Among them, 4 also increased GST activity. While p-bromo-substituted chalcone 8 was the best inducer of QR it decreased hepatic GST expression and cytochrome P450, being the most effective decreasing cytochrome P450-expression. Thienyl-chalcone 20 being the bioisostere of chalcone 4 did not display the same in vivo profile in the phase I level modification. As chalcone 4 its bioisostere, chalcone 20, displayed low DNA strand breakage and absence of mutagenicity. Also, in our preliminary in vivo tumourigenesis/chemopreventive and acute-toxicity studies, chalcones 4, 6 and 8 showed the best behaviours as CPA justifying additional studies that are ongoing.
