Objective: Conjugating quinolones with different bioactive pharmacophores to obtain potent anticancer active agents. Methods: Fused pyrazolopyrimidoquinolines 3a-d, Schiff bases 5, 6a-e, two hybridized systems: pyrazolochromenquinoline 7 and pyrazolothiazolidinquinoline 8, different substituted thiazoloquinolines 13-15 and thiazolo[3,2-a]pyridine derivatives 16a-c were synthesized. Their chemical structures were characterized through spectral and elemental analysis, cytotoxic activity on five cancer cell lines, caspase-3 activation, tubulin polymerization inhibition and cell cycle analysis were evaluated. Results: Four compounds 3b, 3d, 8 and 13 showed potent activity than doxorubicin on HCT116 and three compounds 3b, 3d and 8 on HEPG2. These promising derivatives showed increase in the level of caspase-3. The trifloromethylphenyl derivatives of pyrazolopyrimidoquinolines 3b and 3d showed considerable tubulin polymerization inhibitory activity. Both compounds arrested cell cycle at G2/M phase and induced apoptosis. Conclusion: Compounds 3b and 3d can be considered as promising anticancer active agents with 70% of colchicine activity on tubulin polymerization inhibition and represent hopeful leads that deserve further investigation and optimization.

Several recent reports have demonstrated that nonsteroidal anti-inflammatory drugs (NSAIDs) inhibit the growth of various malignant cells suggesting their application as anticancer agents. In this study, we prepared six nanometer-sized prodrugs (nanoprodrugs) of NSAIDs, ibuprofen, indomethacin, and naproxen through the spontaneous emulsification mechanism using monomeric and dimeric derivatives of the NSAIDs. We evaluated their effect on the proliferation of U87-MG glioma cells by cell counting, WST-1 cell proliferation reagent, and propidium iodide incorporation. The two ibuprofen nanoprodrugs inhibited the cell growth more potently than the indomethacin nanoprodrugs, whereas the naproxen nanoprodrugs did not show any significant effect. Remarkably, ibuprofen did not show any effect at an equimolar concentration. Approximately, 4.4% of the ibuprofen nanoprodrugs was found in the cell, whereas no ibuprofen could be detected suggesting that the superior effect of the nanoprodrugs can be attributed to the efficient cellular uptake of the nanoprodrugs.

With an aim to develop more effective and affordable anticancer agents possessing a unique mechanism of action, we designed and synthesized derivatives of spirooxindole-pyrrolidine heterocyclic hybrids in good yields through a one-pot three-component (3+2) cycloaddition strategy. The synthesized compounds were characterized thoroughly for the physicochemical properties by making use of FT-IR, NMR spectroscopy, and mass spectrometry. Further, these compounds have been evaluated for the influence of anticancer activity against HepG2 cells up to 200 µg/mL concentration. The highly active molecular scaffold was tested for the in-depth mechanistic studies, and it was found that the major pathway of cell death is apoptosis which occurs through the induction of reactive oxygen species followed by the involvement of caspases.
