  Synthesis and Anticancer Activities of 5,6,7-Trimethylbaicalein Derivatives

  摘要：

  本研究旨在基于自然界中存在的黄芩素，一种来自黄芩根的黄酮类化合物，开发潜在的抗癌药物。通过将肉桂酸衍生物转化为相应的氯化物，然后在BF3·Et2O存在下与3,4,5-三甲氧基苯酚缩合，得到查尔酮。这些中间体在DMSO/I2的作用下发生分子内环化，得到所需的三甲氧基黄芩素衍生物。通过MTT比色法测定经测试化合物处理2天后的细胞活力。结果表明，大多数衍生物显示出对Hep G2细胞增殖抑制作用的提升。化合物9的抑制作用最强，其在25 μM浓度下细胞活力降至<2%。对于Hep 3B细胞，8a、8b和8f表现出中等程度的增殖抑制作用，需要25 μM浓度才能将活力降低至约30%。另一方面，前列腺DU145细胞的耐药性更强。大多数衍生物仅在100 μM或更高浓度下才导致DU145细胞60%的抑制率。

  A series of scutellarein-O-alkylamine derivatives were designed, synthesized and tested as multifunctional agents for the treatment of Alzheimer's disease (AD). The results showed that most of these compounds exhibited good multifunctional activities. Among them, compound 16d demonstrated significant metal chelating properties, moderate acetylcholinesterase (AChE) inhibitory and anti-oxidative activity, and excellent inhibitory effects on self-induced A beta(1-42) aggregation, Cu2+-induced A beta(1-42) aggregation, human AChE-induced A beta(1-40) aggregation and disassembled Cu2+-induced aggregation of the well-structured A beta(1-42) fibrils. Both kinetic analysis of AChE inhibition and molecular modeling study suggested that 16d binds simultaneously to the catalytic active site and peripheral anionic site of AChE. Moreover, compound 16d showed a good protective effect against H2O2-induced PC12 cell injury, with low toxicity in SH-SY5Y cells. Furthermore, the step-down passive avoidance test showed this compound significantly reversed scopolamine-induced memory deficit in mice. Thus, 16d was shown to be an interesting multifunctional lead compound worthy of further study. (C) 2015 Elsevier Masson SAS. All rights reserved.

  The aim of this study was to develop potential anticancer agents based on a naturally occurring baicalein, a flavonoid from Scatellariae radix. Cinnamic acid derivatives were converted to corresponding chlorides and then condensed with 3,4,5-trimethoxyphenol in the presence of BF3·Et2O to give chalcones. Intramolecular cyclization of these intermediates by the actions of DMSO/I2 afforded the desired trimethylbaicalein derivatives. Cell viability after treatment with the tested compound for 2 d was determined by a colorimetric MTT assay. The results indicated that most of the derivatives showed improved inhibition of proliferation of Hep G2 cells. Compound 9 was the most potent, in which the cell viability was reduced to <2% at the 25 μM level. In the case of Hep 3B cells, 8a, 8b and 8f showed moderate inhibition of their proliferation and 25 μM was required to reduce the viability to ca. 30%. On the other hand, prostate DU145 cells were more resistant. Most of the derivatives caused a 60% inhibition of DU145 cells only at a concentration of 100 μM or above.

  To discover multifunctional agents for the treatment of Alzheimer's disease (AD), a series of scutellarein carbamate derivatives were designed and synthesized based on the multitarget-directed ligand strategy. Their acetylcholinesterase and butyrylcholinesterase inhibitory activities, antioxidant activities, metal-chelating properties and neuroprotective effects against hydrogen peroxide induced PC12 cell injury were evaluated in vitro. The results showed that most of the synthetic compounds exhibited good multifunctional activities. In particular, compound 15c exhibited dual inhibitory potency on acetylcholinesterase and butyrylcholinesterase with IC50 values of 0.57 and 22.6 mu M, respectively, and good antioxidative activity, with a value 1.3-fold of Trolox. In addition, 15c acted as a selective biometal chelator and possessed neuroprotective effects. Furthermore, 15c could cross the blood-brain barrier (BBB) in vitro and had significant neuroprotective effects in scopolamine-induced cognitive impairment in mice. Taken together, these results suggest that compound 15c might be a potential multifunctional agent for the treatment of AD. (c) 2015 Elsevier Ltd. All rights reserved.
