通过在室温下二氯甲烷中相应的咪唑鎓或苯并咪唑鎓氯化物与Ag 2 O的相互作用,合成了八种新的香豆素取代的银(I)N杂环卡宾(NHC)配合物。这些配合物的结构是在元素分析,1 H NMR,13 C NMR,IR和质谱技术的基础上建立的。卡宾前体和NHC银配合物的抗微生物活性针对标准菌株进行了测试:粪肠球菌,金黄色葡萄球菌,大肠杆菌,铜绿假单胞菌和真菌白色念珠菌和热带假丝酵母。结果表明,所有化合物均能抑制所有细菌和真菌菌株的生长,并且某些复合物对不同微生物具有良好的活性。在所有化合物中,亲脂性最强的双[1-(4-亚甲基-6,8-二甲基-2 H-铬-2-(one)-3-(萘-2-基甲基)苯并咪唑-2-亚烷基]银(I)银二氯乙酸盐(5e)被发现是最活跃的。

13-tetramethoxy-3-methyl-4,5-dihydro-3H-phenanthro[1,2-d]-azepines have been synthesized from 8,9,11,12-tetramethoxy-2-methyl-3,4-dihydronaphtho[2,1-f]isoquinolinium perchlorate by pyridine-azepine recyclization. The resulting compounds have revealed a pronounced antibacterial activity against Staphylococcus aureus (strain P-209) and Escherichia coli (field strain 078). Some of these compounds have a moderate fungistatic

novel one-pot synthetic route to the poorly studied 4-heteroaryl-1,2-dihydro-3-benzazepine motif from 3,4-dihydroisoquinolinium compounds is described. The synthetic approach is based on heterocyclic ring expansion of isoquinoline substrates upon reaction with chloromethyl-substituted heterocycles. The scope and limitations of the reaction were investigated to give a series of novel heteroaryl-3-benzazepines

The alkylation of o-cyanophenol by 4-chloromethylcoumarins and subsequent intramolecular condensation by the cyano and methylene groups gives substituted 4-(3-amino-2-benzo-furanyl)coumarins. We studied the reactions of these compounds with acylating agents as well as with aldehydes, which lead to the 6H-[1]benzofuro[3,2-b]chromeno[4,3-d]pyridin-6-one system as the result of consecutive transformations

study, coumarin‐bearing three pyridinium and three tetra‐alkyl ammonium salts were synthesized. The compounds were fully characterized by 1H‐ and 13C‐NMR, LC/MS and IR spectroscopic methods and elemental analyses. The cytotoxic properties of all compounds were tested against human liver cancer (HepG2), human colorectal cancer (Caco‐2) and non‐cancer mouse fibroblast (L‐929) cell lines. Some compounds
在本研究中,合成了带有香豆素的三吡啶鎓和三种四烷基铵盐。通过 1H- 和 13C-NMR、LC/MS 和 IR 光谱方法以及元素分析对化合物进行了全面表征。测试了所有化合物对人肝癌 (HepG2)、人结直肠癌 (Caco-2) 和非癌小鼠成纤维细胞 (L-929) 细胞系的细胞毒性。一些化合物的细胞毒性与标准药物顺铂相当。化合物对革兰氏阴性大肠杆菌和革兰氏阳性枯草芽孢杆菌的抗菌特性进行了测试,但这些化合物对这两种细菌都没有任何抗菌作用。用人碳酸酐酶 I 和 II 以及黄嘌呤氧化酶的活性测试了所有化合物的酶抑制特性。所有化合物分别比标准药物乙酰唑胺和别嘌呤醇更有效地抑制这两种酶。生物学评价结果表明,离子和水溶性香豆素衍生物是进一步研究特别是酶抑制领域的有前途的结构。

New substituted 4-chloromethylcoumarins that were used as alkylating agents to modify cytisine were synthesized by Pechmann condensation. A series of 4-(12-cytisylmethyl)coumarins containing pharmacophores of the natural heterocycles coumarin and cytisine in a single molecule was prepared. The alkylation gave the best results if diisopropylethylamine was used as the base.
