  A convenient and biogenetic type synthesis of few naturally occurring chromeno dihydrochalcones and their in vitro antileishmanial activity

  摘要：

  2',2'-Dimethyl chromeno dihydrochalcones are very rare in nature as plant secondary metabolites. Recently we have reported three such compounds from the plant Crotalaria ramosissima. Chromeno dihydrochalcones contain a 2',2'-dimethyl benzopyran system, which are frequently encountered in many natural products and exhibit a variety of biological activities. We here report the strategy to conveniently synthesize naturally occurring chromeno dihydrochalcones by biogenetic type pyridine or Amberlyst-15 catalyzed chromenylation of dihydrochalcones and in vitro antileishmanial activity of chromeno dihydrochalcones and their intermediates.

  licorice, is the most promising antimalarial compound reported so far. In continuation of our drug discovery program, we isolated two similar chalcones, medicagenin (II) and munchiwarin (III), from Crotalaria medicagenia, which exhibited antimalarial activity against Plasmodium falciparum. A library of 88 chalcones were synthesized and evaluated for their in vitro antimalarial activity. Among these, 67,

  从中国甘草的根中分离得到的Licochalcone A（I）是迄今为止报道的最有前途的抗疟化合物。在继续我们的药物发现计划时，我们从猪屎豆属中分离了两个类似的查耳酮，medicageninin（II）和munchiwarin（III），它们对恶性疟原虫具有抗疟活性。合成了88个查耳酮的文库，并对其体外抗疟活性进行了评估。在这些中，67，68，74，77，和78显示出在体外对抗疟疾活性良好恶性疟原虫具有低细胞毒性的3D7和K1菌株。这些查耳酮还显示出寄生虫约瑟氏疟原虫（N-67株）感染的瑞士小鼠的寄生虫病减少和存活时间增加。药代动力学研究表明，不良的ADME特性导致口服生物利用度低。分子对接研究揭示了这些抑制剂在falcipain-2（FP-2）酶的活性位点的结合方向。化合物67，68，和78显示出对主要血红蛋白降解半胱氨酸适度抑制活性蛋白酶FP-2。

  The hemisynthesis of three new chalcones, namely kenzanol, kelianol A, and kelianol B, from Dorstenia barteri (Moraceae) is described here for the first time. The synthetic pathways employed in this work involved the pyrolysis and catalytic hydrogenation of readily available and starting materials, 4-hydroxylonchocarpin and isobavachalcone, two major constituents of the herbaceous plant D. barteri

  此处首次描述了来自 Dorstenia barteri（桑科）的三种新查耳酮的半合成，即 kenzanol、kelianol A 和 kelianol B。这项工作中采用的合成途径涉及容易获得的起始材料 4-羟基磷酰胆碱和异巴伐查酮（草本植物 D. barteri 的两种主要成分）的热解和催化氢化。所有化合物的结构解析均通过质谱、红外、紫外、一维和二维核磁共振分析进行，并与以前的报告进行比较。

  Crotaoprostrin, a chalcone not yet known as a plant constituent, was isolated from the aerial parts of the Indian medicinal plant Crotalaria prostrata. The structures of the chalcone polyarvin and the partially hydrogenated naturally occurring derivatives crotaramin, crotaramosmin, and crotin were confirmed by chemical synthesis.
