Quinoline-azetidinone hybrids: Synthesis and in vitro antiproliferation activity against Hep G2 and Hep 3B human cell lines
摘要:
In search of new heterocyclic anticancer agents, a new quinoline-azetidinone hybrid template have been designed, synthesized and screened for their cytotoxic activity against human cancer cell lines such as Hep G2, and Hep 3B by the MTT assay and results were compared with paclitaxel, 5-fluorouracil and doxorubicin. Interestingly, some of the compounds were found significantly active against both cell lines. The compound 6f (IC50 = 0.04 +/- 0.01 mu M) exhibited potent antiproliferation activity against Hep G2 cell line, and 6j compound (IC50 = 0.66 +/- 0.01 mu M) demonstrated potent antiproliferation activity against Hep 3B cell line and provide to be more potent as cytotoxic agents than standard drugs. Morphological changes suggest the induction of apoptosis and describe the mechanism of action of these hybrid antitumor agents. (C) 2017 Elsevier Ltd. All rights reserved.

mechanism of inflammatory activity of the potent compound 3e was further investigated using a series of biochemical, molecular and microscopic techniques. Further structure activity relationship (SAR) study was carried out to validate the anti-inflammatory activities of the active compounds. Our experimental data revealed that the active moiety i.e. compound 3e majorly causes inhibition of TLR4 signaling

A series of twenty-one 7-chloro-4-quinolinylhydrazones (3a-u) have been synthesized and evaluated for their in vitro antibacterial activity against Mycobacterium tuberculosis H(37)Rv. The compounds 3f, 3i and 3o were non-cytotoxic and exhibited an important minimum inhibitory concentration (MIC) activity (2.5 mu g/mL), which can be compared with that of the first line drugs, ethambutol (3.12 mu g/mL) and rifampicin (2.0 mu g/mL). These results can be considered an important start point for the rational design of new leads for anti-TB compounds. (C) 2009 Elsevier Ltd. All rights reserved.
