With the aim of finding new anti-inflammatory drugs, a series of new Glycyrrhetinic acid derivatives (1–34) have been designed and synthesized by structural modification, and their anti-inflammatory activities in vitro have been evaluated. The anti-inflammatory activities assay demonstrated that compound 5b suppressed the expression of pro-inflammatory cytokines including IL-6, TNF-α and NO, it also
A facile and an efficientprotocol has been developed for the synthesis of novel1,2,3-triazolesubstituted4H-chromenederivatives in single pot by multicomponent reaction of 1,3-cyclohexanedione, malononitrile and 1-substituted 1,2,3-triazole-5-aldehyde using potassium carbonate as catalyst.

A series of novel (E)-2-[(1-phenyl-1H-1,2,3-triazol-4-yl)methylene]-2,3-dihydro-1H-inden-1-one derivatives has been synthesized by condensation of 1-phenyl-1H-1,2,3-triazole-4-carbaldehydes with 2,3-dihydro-1H-inden-1-one. The synthesized compounds are characterized by 1H and 13C NMR, and mass spectrometry, and tested in vitro against four bacterial organism and two fungal organisms. The tests data
一系列新的(E)-2-[(1-苯基-1 H -1,2,3-三唑-4-基)亚甲基] -2,3-二氢-1 H-茚满-1-一衍生物具有通过1-苯基-1 H -1,2,3-三唑-4-甲醛与2,3-二氢-1 H -inden-1-one的缩合合成。合成的化合物通过1 H和13 C NMR表征,并进行质谱分析,并针对四种细菌生物体和两种真菌生物体进行了体外测试。测试数据证明了化合物的中等至良好活性。
An efficient NaHSO3-promoted protocol for chemoselective synthesis of 2-substituted benzimidazoles in water
NaHSO3 was more than 11 equivalents, the 2-substituted benzimidazole could be highly selectively formed as the sole product. NaHSO3 was firstly reacted with aldehyde to form the aldehyde sodium bisulfite, which reacted with o-phenylenediamine to form the 2-substituted benzimidazole and inhibited the formation of 1,2-disubstituted benzimidazole. This protocol solved the poor selectivity problem appearing

presence of KOH. The title compounds were evaluated for their in vitro anticancer activity using MTT assay against four cancer cell lines: A549 (lung), HT-29 (colon), MCF-7 (breast), and A375 (melanoma). Most compounds displayed good anticancer activity, but hydroxy- and nitro-substituted derivatives showed higher activity than the others.
摘要通过将相应的1-芳基-1 H -1,2,3-三唑-4-甲醛与噻唑烷-2,4-二酮缩合,合成了一系列新的1,2,3-三唑基噻唑烷二酮类似物。KOH。使用MTT测定法针对四种癌细胞系:A549(肺),HT-29(结肠),MCF-7(乳腺癌)和A375(黑素瘤)评估了标题化合物的体外抗癌活性。大多数化合物显示出良好的抗癌活性,但是羟基和硝基取代的衍生物显示出比其他化合物更高的活性。
