  含有若丹宁-3-脂肪酸部分作为潜在抗菌剂的新型1,3-二芳基吡唑衍生物的合成

  摘要：

  在本研究中，合成了一系列带有若丹宁-3-脂肪酸部分的1,3-二芳基吡唑衍生物，并测试了它们对各种革兰氏阳性和革兰氏阴性细菌的抗菌活性。按照维尔斯迈尔-哈克（Vilsmeier-Haack）策略，合成了1,3-二芳基-4-甲酰基吡唑类化合物作为关键中间体。MIC为2μg/ mL的几种化合物显示出比对照更强的耐甲氧西林金黄色葡萄球菌（MRSA）的抗菌活性。这些化合物均未显示出对革兰氏阴性细菌的任何活性。

  Two series of 1,3-diphenyl-1H-pyrazole derivatives containing rhodanine-3-alkanoic acid groups were identified as competitive protein tyrosine phosphatase 1B (PTP1B) inhibitors. Among the compounds studied, IIIv was found to have the best in vitro inhibition activity against PTP1B (IC50 = 0.67 ± 0.09 µM) and the best selectivity (9-fold) between PTP1B and T-cell protein tyrosine phosphatase (TCPTP)

  含有若丹宁-3-链烷酸基团的两个系列的1,3-二苯基-1H-吡唑衍生物被确定为竞争性蛋白酪氨酸磷酸酶1B（PTP1B）抑制剂。在研究的化合物中，发现IIIv对PTP1B具有最佳的体外抑制活性（IC50 = 0.67±0.09 µM），并且在PTP1B和T细胞蛋白酪氨酸磷酸酶（TCPTP）之间具有最佳选择性（9倍）。分子对接研究表明，化合物IIIm，IIIv和IVg可同时在催化位点和相邻的PTyr结合位点占据。这些结果为设计PTP1B和其他PTP抑制剂提供了新的先导化合物。

  Three series of 1,3-diaryl pyrazole derivatives bearing aminoguanidine or furan-2-carbohydrazide moieties have been synthesized, characterized and evaluated for antibacterial and anti-inflammatory activities. Most of the synthesized compounds showed potent inhibition of several Gram-positive bacterial strains (including multidrug-resistant clinical isolates) and Gram-negative bacterial strains with minimum inhibitory concentration values in the range of 1-64 mu g/mL. Compounds 6g, 6l and 7l presented the most potent inhibitory activity against Gram-positive bacteria (e.g. Staphylococcus aureus 4220), Gram-negative bacteria (e.g. Escherichia coli 1924) and the fungus, Candida albicans 7535, with minimum inhibitory concentration values of 1 or 2 mu g/mL. Compared with previous studies, these compounds exhibited a broad spectrum of inhibitory activity. Furthermore, compound 7l showed the greatest anti-inflammatory activity (93.59% inhibition, 30 min after intraperitoneal administration), which was more potent than the reference drugs ibuprofen and indomethacin.

  In the present study, a series of novel 1,3-diphenyl-1H-pyrazoles functionalized with phenylalanine-derived rhodanine derivatives were synthesized and evaluated for their antibacterial activity. Compounds 4, 6, 9, 10, 12 and 15 exhibited stronger activity than the standard drugs, norfloxacin and oxacillin, with MIC values of 1 mu g/mL against methicillin-resistant Staphylococcus aureus and quinolone-resistant S. aureus. None of the compounds showed any activity against Gram-negative bacteria. (C) 2012 Elsevier Masson SAS. All rights reserved.
