  Prenylflavonoid variation in Humulus lupulus: distribution and taxonomic significance of xanthogalenol and 4′-O-methylxanthohumol

  摘要：

  The resins produced by either lupulin or leaf glands of over 120 plants of Humulus lupulus and one plant of H. japonicus (Cannabinaceae) were analyzed for the presence of prenylated flavonoids. The H. lupulus taxa investigated were H. lupulus var. lupulus from Europe, H. lupulus var. cordifolius from Japan, and H. lupulus From North America. Fifty-two of the plants examined were cultivars of European, American, and Japanese origin, Twenty-two flavonoids were detected in the glandular exudates of. H. lupulus by HPLC-MS-MS. Xanthohumol (3'-prenyl-6'-O-methylchalconaringenin) was the principal prenylflavonoid in all H. lupulus plants and was accompanied by 11 structurally similar chalcones. Ten flavonoids were identified as the flavanone isomers of these chalcones. Three other prenylchalcones were isolated from H. lupulus cv. 'Galena', one of which was identified as 3'-prenyl-4'-O-methylchalconaringenin (named 'xanthogalenol'). The distribution of three 4'-O-methylchalcones, i.e, xanthogalenol, 4'-O-methylxanthohumol, and 4',6'-di-O-methylchalconaringenin, was found to be limited to wild American plants from the Missouri-Mississippi river basin, H. lupulus var. cordifolius, and most of their descendents, These 4'-O-methylchalcones were absent from cultivars of European origin; and from wild hops from Europe and southwestern USA, The flavonoid dichotomy (presence versus absence of 4'-O-methylchalcones) indicates that there are at least two evolutionary lineages within H. lupulus (European and Japanese-American). which is in agreement with morphological, molecular, and phytogeographical evidence. Leaf glands of H. japonicus from eastern Asia did not produce the N. lupulus prenylflavonoids. (C) 2000 Elsevier Science Ltd. All rights reserved.

  This study was designed to synthesize and evaluate flavanone derivatives with phenylcarbamate moiety as potent acetylcholinesterase (AChE) inhibitors and anti-amnestic agents for management of AD. The synthesis of carbamate-substituted flavanone derivatives involved base-catalysed Claisen-Schmidt condensation reaction of 2-hydroxy acetophenone/2-hydroxy-4,6-dimethoxyacetophenone with differently substituted

  本研究旨在合成和评估具有氨基甲酸酯部分的黄烷酮衍生物，作为有效的乙酰胆碱酯酶（AChE）抑制剂和抗记忆删除剂，用于治疗AD。氨基甲酸酯取代的黄烷酮衍生物的合成涉及2-羟基苯乙酮/ 2-羟基-4,6-二甲氧基苯乙酮与不同取代的苯甲醛的碱催化的Claisen-Schmidt缩合反应，以产生不同取代的查耳酮，其在回流时经历分子内氧化环化用冰醋酸制得黄烷酮化合物。此后，在石油醚和三乙胺存在下，将黄烷酮化合物与异氰酸苯酯回流，得到苯基氨基甲酸酯取代的黄烷酮衍生物。以多奈哌齐为标准药物，体外筛选合成的化合物对AChE的抑制活性。最有效的测试化合物通过Morris水迷宫测试，评价了（5f '）在体内东pol碱（0.4mg / kg）引起的健忘症中的记忆恢复作用。所有化合物均显示出对AChE的抑制活性，其中氨基甲酸酯取代的5,7-二甲氧基黄烷酮衍生物（5a' - 5g '）是最有效的化合物，IC 50为21

  Discovery and efficient synthesis of new promising leads have a central role in agrochemical science. Reported herein is the sakuranetin-directed synergistic exploration of an asymmetric synthesis and an antifungal evaluation of chiral flavanones. A new palladium catalytic system with CarOx-type ligands was successfully identified for the highly enantioselective addition of arylboronic acids to chromones

  新的有前途的先导化合物的发现和有效合成在农业化学科学中具有核心作用。本文报道了以 sakuranetin 为导向的不对称合成协同探索和手性黄烷酮的抗真菌评估。成功鉴定了一种具有 CarOx 型配体的新型钯催化体系，用于将芳基硼酸高度对映选择性地添加到色酮中。这使得手性黄烷酮群（产率高达 98% 和 ee 高达 97%）的简便和可编程构建成为可能，其中（R)-pinostrobin 无需费力的保护/去保护操作即可有效构建。其在不对称诱导和功能耐受方面的良好表现扩大了药学上重要的黄烷酮的化学空间。揭示和总结了基于抗真菌活性和简明构效关系模型的黄烷酮手性分化。这个协同项目最终获得了天然前所未有的黄烷酮，其抗真菌潜力比樱花素更好，其中黄烷酮54的R-对映异构体(EC 50 = 0.8 μM) 表现出比啶酰菌胺对立枯丝核菌更好的性能. 与 FRAC 中的商业杀菌剂相比，新型支架和预测的新靶标强化了进一步探索的价值。
