  2-苯乙烯基色酮衍生物作为有效的和选择性的单胺氧化酶B抑制剂。

  摘要：

  合成了18种2-苯乙烯基色酮衍生物（见图1），并评估了它们的单胺氧化酶（MAO）A和B抑制活性。与衍生物（阳性对照）相比，许多衍生物抑制MAO-B的作用，而且大多数都选择性抑制MAO-B。在这18种衍生物中，在R 1上具有甲氧基和在R 4上具有氯的化合物9表现出最佳的MAO-B抑制活性（IC 50  = 17±2.4 nM）和最佳的MAO-B选择性（IC 50对MAO-A而言） / IC 50（对于MAO-B = 1500）。化合物9的抑制方式对MAO-B的竞争是可逆的。使用分子操作环境（MOE）和Dragon使用2-苯乙烯基色酮衍生物的pIC 50值进行了定量构效关系（QSAR）分析，证明了MAO-B抑制活性和MAO-B选择性的描述分别为1734和121，显示出显着的相关性（P <0.05）。然后，我们通过使用AutoGPA的三维QSAR研究，将2-苯乙烯基色酮结构作为有用的支架进行了研

  The structure-activity relationship study of 2-styrylchromones against carcinoma cell growth is discussed in the present report. Taking advantage of 2-styrylchromone as a molecular template, a series of structural modifications was carried out and examined on several carcinoma cell lines. Interestingly, AGS cells exhibited more sensitivity in response to methoxy-bearing compounds, of which compound 23 (3,4,5-trimethoxy group on ring B) showed the most potent activity with a GI(50) value of 1.3 mu M. Surprisingly, as methoxy groups in 12 and 24-27 were demethylated to generate their hydroxyl counterparts 28-32, none of them displayed appreciable activity against all carcinoma cells. We further confirmed the pivotal role of rigidity for growth inhibitory activity between the rigid 12 and its flexible counterpart 33. Taken together, in the present report, we have clearly demonstrated the structure-activity relationship study of 2-styrylchromones targeting carcinoma cell growth.

  A number of DNA methylation inhibitors are described. The DNA methylation inhibitors were identified using a two-component enhanced green fluorescent protein reporter system to screen a compound library containing procainamide derivatives. The DNA methylation inhibitors can be used for cancer therapy and prevention.

  A series of eighteen 2-styrylchromone derivatives (see Chart 1) were synthesized and evaluated for their monoamine oxidase (MAO) A and B inhibitory activities. Many of the derivatives inhibited MAO-B comparable to pargyline (a positive control), and most of them inhibited MAO-B selectively. Of the eighteen derivatives, compound 9 having methoxy group at R1 and chlorine at R4 showed both the best MAO-B
