Thirty chalcone derivatives were synthesized via a base catalyzed Claisen Schmidt condensation and evaluated for their anti-methicillin-resistant Staphylococcus aureus (MRSA) activity alone and in combination with norfloxacin. Among these, 5 derivatives namely trans-3-(1H-indol-3-yl)-1-(4′-benzyloxyphenyl)-2-propen-1-one (2), 1-(4″-biphenyl)-3-(3′4′-dihydroxyphenyl)-2-propen-1-one (11), 1-(4″-hydroxy-3

A new series of monomer and dimer derivatives of dihydroartemisinin (DHA) containing substituted chalcones as a linker were synthesized and investigated for their cytotoxicity in human cancer cell lines HL-60 (leukemia), Mia PaCa-2 (pancreatic cancer), PC-3 (prostate cancer), LS180 (colon cancer) and HEPG2 (hepatocellular carcinoma). Some of these derivatives have greater antiproliferative and cytotoxic
合成了一系列含有取代查耳酮作为接头的双氢青蒿素 (DHA) 单体和二聚体衍生物,并研究了它们在人类癌细胞系 HL-60(白血病)、Mia PaCa-2(胰腺癌)、PC-3 中的细胞毒性(前列腺癌)、LS180(结肠癌)和 HEPG2(肝细胞癌)。在测试的细胞系中,这些衍生物中的一些具有比母体化合物 DHA 更大的抗增殖和细胞毒性作用。所有化合物的结构均经IR、1 H NMR和质谱数据证实。在新衍生物中,化合物8、14、15、20和24被发现对测试的人类癌细胞系比亲本 DHA 更活跃。发现 DHA 衍生物在人类白血病细胞系中最活跃,化合物8、14、15、20和24在48小时内的IC 50值小于 1 μM,而 DHA 在同一时间段的 IC 50值为2 μM 。该系列中最有效的化合物8的 IC 50 = 0.3 μM(与多柔比星相当(IC 50 = 0.3 μM))和15的 IC 50 =
Indole chalcones: Design, synthesis, in vitro and in silico evaluation against Mycobacterium tuberculosis
compounds against H37Rv strain of Mycobacteriumtuberculosis. Within this library of compounds, (E)-1-(furan-3-yl)-3-(1H-indol-3-yl)prop-2-en-1-one (18), (E)-3-(1H-indol-3-yl)-1-(thiophen-2-yl)prop-2-en-1-one (20) and (E)-2-((1H-indol-2-yl)methylene)cyclopentan-1-one (24) displayed high anti-tubercular activity at 50 μg/ml with MIC values of 210, 197 and 236 μM respectively. The in-silico studies revealed
4,6-diaryl and 4,6-aryl-indolyl substituted 3-cyano-2-aminopyridines were synthesized and submitted to evaluation for their anti-inflammatory, analgesic and antipyretic activity. The electronegativity of the substituents and their displacement on the 4- or 6-aryl ring of the 4,6-diaryl-3-cyano-2-aminopyridine nucleus (3a-q) influenced the anti-inflammatory activity which was higher in the presence of electron-realising groups. The introduction of the indol-3-yl substituent in the 4-position of the 3-cyano-2-aminopyridine nucleus (6a-x) increased the anti-inflammatory and analgesic power, but there was no evidence of the relationship among the electronic characteristic of the substituents, their displacement on the 6-phenyl ring and the activity. Conversely, the displacement of the 2-hydroxyphenyl group in the 4-position (4a-e) and of the indol-3-yl group in the 6-position (8h-w) decreased the anti-inflammatory activity. All derivatives did not show any significative antipyretic activity. (C) Elsevier, Paris.
