Abstract: A series of pyridazino[4,5-b]indole derivatives containing alkyl-, benzyl- and phenacyl-substituted 1,2,3-triazolylmethyl units was synthesized using click chemistry approach. All 30 compounds of the series were screened in vitro against four cancer cell lines, viz. breast cancer cells MDA-MB-231 and MCF 7, human primary glioblastoma U-87 and human neuroblastoma IMR-32 cell lines. Most of the compounds exhibited potent cancer cell growth inhibition activity at very low micromolar concentrations. The IC50 value of compounds 7v and 7x against human neuroblastoma IMR-32 cell line is 0.07 and 0.04 ?M, respectively. Among the tested compounds, ten compounds showed IC50 value less than 1 ?M against MDA-MB-231 cells, whereas against IMR-32 cells, nine compounds and, against U-87 cells, six compounds showed similar inhibition activity. Further, these molecules exhibited prominent binding affinity and docking scores in the molecular simulation study with the target enzyme PI3 kinase. Graphical Abstract: This paper illustrates the synthesis of new fused indole-pyridazinone derivatives containing substituted 1,2,3-triazoles via click chemistry approach. Most of the compounds exhibited potent cancer cell growth inhibition activity at very low micromolar concentrations.
