  Identification of anticancer agents based on the thieno[2,3-b]pyridine and 1H-pyrazole molecular scaffolds

  摘要：

  Structural similarity search of commercially available analogues of thieno[2,3-b]pyridine and 1H-pyrazole derivatives, known anticancer agents, resulted in 717 hits. These were docked into the phosphoinositide specific-phospholipase C (PLC) binding pocket, the putative target of the compounds, to further focus the selection. Thirteen derivatives of the thieno[2,3-b]pyridines were identified and tested against the NCI60 panel of human tumour cell lines. The most active derivative 1 was most potent against the MDA-MB-435 melanoma cell line with GI(50) at 30 nM. Also, it was found that a piperidine moiety is tolerated on the thieno[2,3-b]pyridine scaffold with GI(50) = 296 nM (MDA-MB-435) for derivative 10 considerably expanding the structure activity relationship for the series. For the 1H-pyrazoles four derivatives were identified using the in silico approach and additionally ten were synthesised with various sub-stituents on the phenyl moiety to extend the structural activity relationship but only modest anticancer activity was found.
