  Importance of the B Ring and Its Substitution on the α-Glucosidase Inhibitory Activity of Baicalein, 5,6,7-Trihydroxyflavone

  摘要：

  为了评估黄芩素（5,6,7-三羟基黄酮，1）的 B 环对其强效α-葡萄糖苷酶抑制活性的贡献，我们制备了羟基色酮和 B 环取代的 5,6,7- 三羟基黄酮。缺乏 6-羟基取代的羟基色酮没有显示出任何抑制活性，而 5,6,7-三羟基-2-甲基色酮（5）则显示出较高的活性。在测试的 B 环取代的 5,6,7-三羟基黄酮中，4′-羟基、3′,4′-二羟基和 3′,4′,5′-三羟基取代的衍生物的活性高于 1。结果表明，1 的 B 环虽然对活性有利，但并不是必需的；5,6,7-三羟基黄酮 B 环上的羟基取代对活性有利，而甲氧基取代则不利；5,6,7-三羟基黄酮至少需要 4′-羟基取代才能提高活性，羟基的数量与活性无关。

  Increasing parasite resistance to nearly all available antimalarial drugs becomes a serious problem to human health and necessitates the need to continue the search for new effective drugs. Recent studies have shown that clinically utilized HIV-1 protease (HIV-1 PR) inhibitors can inhibit the in vitro and in vivo growth of Plasmodium falciparum. In this study, a series of chromone derivatives possessing HIV-1 PR inhibitory activity has been tested for antimalarial activity against P. falciparum (K1 multi-drug resistant strain). Chromone 15, the potent HIV-1 PR inhibitor (IC50 = 0.65 mu M), was found to be the most potent antimalarial compound with IC50 = 0.95 mu M while primaquine and tafenoquine showed IC50 = 2.41 and 1.95 mu M, respectively. Molecular docking study of chromone compounds against plasmepsin II, an aspartic protease enzyme important in hemoglobin degradation, revealed that chromone 15 exhibited the higher binding affinity (binding energy = -13.24 kcal/mol) than the known PM II inhibitors. Thus, HIV-1 PR inhibitor in chromone series has the potential to be a new class of antimalarial agent. (C) 2014 Elsevier Inc. All rights reserved.

• Importance of the B Ring and Its Substitution on the α-Glucosidase Inhibitory Activity of Baicalein, 5,6,7-Trihydroxyflavone

  Hydroxychromones and B-ring-substituted 5,6,7-trihydroxyflavones were prepared to evaluate the contribution of the B ring of baicalein (5,6,7-trihydroxyflavone, 1) to its potent α-glucosidase inhibitory activity. Hydroxychromones, which lack 6-hydroxyl substitution, did not show any inhibitory activity, while 5,6,7-trihydroxy-2-methylchromone (5) showed high activity. Among the tested B-ring-substituted 5,6,7-trihydroxyflavones, the 4′-hydroxy-, 3′,4′-dihydroxy-, and 3′,4′,5′-trihydroxy-substituted derivatives were found to give more activity than that of 1. The methoxy-substituted derivatives, however, showed less activity than 1. The results suggest that the B ring of 1 was not essential, although advantageous to the activity; hydroxyl substitution on the B ring of 5,6,7-trihydroxyflavones was favorable to the activity, whereas methoxyl substitution was unfavorable; at least 4′-hydroxyl substitution of 5,6,7-trihydroxyflavones was required for enhanced activity, in which the number of hydroxyl groups did not take part.
