CitationIdentification of anticancer agents based on the thieno[2,3-b]pyridine and 1H-pyrazole molecular scaffolds. 2016, 24 (16):3521-6 Bioorg. Med. Chem.
AbstractStructural 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 GI50 at 30nM. Also, it was found that a piperidine moiety is tolerated on the thieno[2,3-b]pyridine scaffold with GI50=296nM (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 substituents on the phenyl moiety to extend the structural activity relationship but only modest anticancer activity was found.
