  Synthesis and pharmacological evaluation of pyrazolo[4,3-c]cinnoline derivatives as potential anti-inflammatory and antibacterial agents

  摘要：

  A series of pyrazolo[4,3-c]cinnoline derivatives was synthesized, characterized and evaluated for anti-inflammatory and antibacterial activity. Test compounds that exhibited good anti-inflammatory activity were further screened for their ulcerogenic and lipid peroxidation activity. Compounds 4d and 41 showed promising anti-inflammatory activity with reduced ulcerogenic and lipid peroxidation activity when compared to naproxen. Docking results of these two compounds with COX-2 (PDB ID: 1CX2) also exhibited a strong binding profile. Among the test derivatives, compound 4i displayed significant antibacterial property against gram-negative (Escherichia coli and Pseudomonas aeruginosa) and gram-positive (Staphylococcus aureus) bacteria. However, compound 4b emerged as the best dual anti-inflammatory antibacterial agent in the present study. (C) 2012 Elsevier Masson SAS. All rights reserved.

  摘要：

  设计并合成了带有哒嗪酮的四个系列的N-甲基吡啶甲基酰胺部分和噻吩并嘧啶部分，并评估了其对三种癌细胞系（A549，HepG2和MCF-7）的IC 50值，并进一步评估了一些所选化合物对c-的活性Met，Flt-3，VEGFR-2，c-Kit和EGFR激酶。三种化合物（35，39和43）比阳性对照Foretinib表现出更多的活性对A549，HepG2和MCF-7细胞系。最有前途的化合物43表现出对A549，HepG2和MCF-7的优异活性，其IC 50为500.58±0.15 µM，0.47±0.06 µM和0.74±0.12 µM的活性分别比福瑞替尼高3.73–5.39倍。基于酶的实验表明，有43种酶选择性抑制c-Met，IC 50值为16 nM，与Foretinib（14 nM）具有相同的活性，并且比化合物5（90 nM）更好。此外，还进行了AO和Annexin V / PI染色和对接研究。

  3-(4-Chlorophenyl)-4-substituted pyrazole derivatives were synthesised and tested for their in vitro antifungal activity. Some compounds showed very good antifungal activity against four pathogenic strains of fungi. The same compounds exhibited an interesting activity against the tested strain of Mycobacterium tuberculosis H37Rv. The results suggest that 1,3,4-oxadiazoles and 5-pyrazolinones bearing

  Inhibitors of alpha-amylase are targets for the development of novel drugs for the treatment of diabetes and obesity. Alpha amylase is an enzyme which increases the bio availability of glucose in the blood. Hence, the inhibition effects of alpha amylase of 2-[1-(4-isobutylphenyl)ethyl]-5-methyl-4-[2-(aryl-substituted)hydrazinylidene]-2,4-dihydro-3H-pyrazol-3-one (4a-l) were investigated, among them compounds 4d, 4f, 4a, and 4g have displayed good inhibitory activity. The compounds with significant results were further evaluated for their molecular modeling study using in silico method. The new series of compounds were synthesized by solvent-free microwave irradiation method and were characterized by spectral and analytical data.

  A series of 7-azaindole derivatives bearing the dihydropyridazine scaffold were synthesized and evaluated for their c-Met kinase inhibitory, and antiproliferative activity against 4 cancer cell lines (HT29, A549, H460, U87MG) were evaluated in vitro. Most compounds showed moderate to excellent potency. Compared to foretinib, the most promising analog 34 (c-Met IC50: 1.06 nM, a multitarget tyrosine kinase inhibitor) showed a 6.4-, 7.8-, and 3.2-fold increase in activity against HT29, A549, and H460 cell lines, respectively. Structure activity relationship studies indicated that mono-EWGs (such as R-2 = F) at 4-position of moiety D was a key factor in improving the antitumor activity. (C) 2017 Elsevier Masson SAS.
