, p. 59 - 68 (2016)
In an attempt to develop newer antitubercular and antibacterial agents against the increasing bacterial resistance, we have designed new quinoline–pyrazole analogs (8a–u) following the molecular hybridization approach. The structure of one of the final compounds, 8a was unambiguously confirmed by single crystal X-ray diffraction (SC-XRD) analysis. The target compounds were evaluated for their antitubercular activity against Mycobacterium tuberculosis and antibacterial activity against three common pathogenic bacterial strains. Four derivatives (8b, 8c, 8j and 8o) displayed significant antitubercular activity. The compounds derived from 8-trifluoromethylquinoline and 6-fluoroquinoline scaffolds with halogen substitution on the pyrazole ring exhibited superior inhibition activity than corresponding 6-methoxyquinoline analogs. The cytotoxic studies revealed that the active compounds are nontoxic to normal Vero cell lines with selectivity index values ≥10, which indicate the suitability of these compounds for further drug development. The in silico molecular docking study demonstrated strong binding affinity of the compounds with the target enzymes (InhA, CYP121 and TMPK) of M. tuberculosis. Further, the in vitro antibacterial activity of compounds 8b, 8c, 8d and 8g is comparable with that of the reference drug, Ciprofloxacin.

Background: Several series of pyrazole derivatives containing (thio) semicarbazide (4a-4h, 5a-5l, 6a-6f, 7a-7c) were designed and synthesized to screen dual inflammatory and antimicrobial activities. Methods: The products were characterized by1
Synthesis and the interaction of 2-(1H-pyrazol-4-yl)-1H-imidazo[4,5-f][1,10]phenanthrolines with telomeric DNA as lung cancer inhibitors
Liu, Jiachun,Chen, Mei,Wang, Yanli,Zhao, Xiaoyin,Wang, Sijia,Wu, Yanling,Zhang, Wen
, p. 36 - 49 (2017/04/06)
A novel series of 2-(1H-pyrazol-4-yl)-1H-imidazo[4,5-f][1,10]phenanthrolines were designed, synthesized and evaluated for their antitumor activity against lung adenocarcinoma by CCK-8 assay, electrophoretic mobility shift assay (EMSA), UV-melting study, wound healing assay and docking study. These compounds showed good inhibitory activities against lung adenocarcinoma. Especially compound 12c exhibited potential antiproliferative activity against A549?cell line with the half maximal inhibitory concentration (IC50) value of 1.48?μM, which was a more potent inhibitor than cisplatin (IC50?=?12.08?μM) and leading compound 2 (IC50?=?1.69?μM), and the maximum cell inhibitory rate being up to 98.40%. Moreover, further experiments demonstrated that compounds 12a–d can strongly interact with telomeric DNA to stabilize G-quadruplex DNA with increased ΔTm values from 12.44 to 20.54?°C at a ratio of DNA to compound 1:10. These results implied that growth inhibition of A549?cells mediated by these phenanthroline derivatives is possibly positively correlated to the fact their interaction with telomeric G-quadruplexs.

scheme or table, p. 4932 - 4935 (2009/05/26)
Necroptosis is a regulated caspase-independent cell death mechanism characterized by morphological features resembling non-regulated necrosis. Necrotatin-7 (Nec-7), a novel potent small-molecule inhibitor of necroptosis, is structurally distinct from previously described necrostatins (Nec-1, Nec-3, Nec-4 and Nec-5). Here, we describe a series of structural modifications and the structure-activity relationship (SAR) of the Nec-7 series for inhibiting necroptosis.
