In this regard, we have recently examined the structure\u2013activity relationship of a new series of seventeen 2-aminothiazole-fused to flavonoid hybrid compounds (TZF) on Tau-overexpressing GBM cells. Here, we evaluated the anticancer activities of the two lead compounds 2 and 9 using multi-cellular spheroids (MCSs) which represent an easy 3D human cell model to mimic GBM organization, physical constraints and drug penetration. The two compounds reduced cell evasion from spheroids up to three times, especially for Tau-expressing cells. As a first step towards a therapeutic approach, we quantified the effects of these compounds on MCS growth using two complementary protocols: single and repeated treatments. A single injection with compound 9 slowed down the growth of MCSs formed with U87 shCTRL cells by 40% at 10 \u00b5M. More interestingly, multiple treatment with compound 9 slowed the growth of U87 shCTRL spheroids by 40% at a concentration of 5 \u00b5M, supporting the increased bioavailability of compound 9 within MCSs. In conclusion, compound 9 deserves particular attention as promising candidate for specifically targeting Tau-expressing cancers such as GBM.<\/jats:p>","DOI":"10.3390\/ijms252111785","type":"journal-article","created":{"date-parts":[[2024,11,4]],"date-time":"2024-11-04T03:57:34Z","timestamp":1730692654000},"page":"11785","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Therapeutic Contribution of Tau-Binding Thiazoloflavonoid Hybrid Derivatives Against Glioblastoma Using Pharmacological Approach in 3D Spheroids"],"prefix":"10.3390","volume":"25","author":[{"ORCID":"https:\/\/orcid.org\/0009-0004-1801-968X","authenticated-orcid":false,"given":"Emmanuelle T.","family":"Relave","sequence":"first","affiliation":[{"name":"Facult\u00e9 des Sciences M\u00e9dicales et Param\u00e9dicales, Institut de Neurophysiopathologie (INP), UMR 7051, CNRS, Aix Marseille Universit\u00e9, 13005 Marseille, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rayane","family":"Hedna","sequence":"additional","affiliation":[{"name":"Facult\u00e9 des Sciences M\u00e9dicales et Param\u00e9dicales, Institut de Neurophysiopathologie (INP), UMR 7051, CNRS, Aix Marseille Universit\u00e9, 13005 Marseille, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-3663-4443","authenticated-orcid":false,"given":"Attilio","family":"Di Maio","sequence":"additional","affiliation":[{"name":"Mediterranean Institute of Marine and Terrestrial Biodiversity and Ecology, IRD, CNRS UMR7263, Aix-Marseille Universit\u00e9, 13013 Marseille, France"},{"name":"Mediterranean Institute of Marine and Terrestrial Biodiversity and Ecology, IRD, NRS UMR7263, Avignon University, 84029 Avignon, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5990-8898","authenticated-orcid":false,"given":"Fran\u00e7ois","family":"Devred","sequence":"additional","affiliation":[{"name":"Facult\u00e9 des Sciences M\u00e9dicales et Param\u00e9dicales, Institut de Neurophysiopathologie (INP), UMR 7051, CNRS, Aix Marseille Universit\u00e9, 13005 Marseille, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6509-4210","authenticated-orcid":false,"given":"Herv\u00e9","family":"Kovacic","sequence":"additional","affiliation":[{"name":"Facult\u00e9 des Sciences M\u00e9dicales et Param\u00e9dicales, Institut de Neurophysiopathologie (INP), UMR 7051, CNRS, Aix Marseille Universit\u00e9, 13005 Marseille, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9914-786X","authenticated-orcid":false,"given":"Maxime","family":"Robin","sequence":"additional","affiliation":[{"name":"Mediterranean Institute of Marine and Terrestrial Biodiversity and Ecology, IRD, CNRS UMR7263, Aix-Marseille Universit\u00e9, 13013 Marseille, France"},{"name":"Mediterranean Institute of Marine and Terrestrial Biodiversity and Ecology, IRD, NRS UMR7263, Avignon University, 84029 Avignon, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8178-2080","authenticated-orcid":false,"given":"Gilles","family":"Breuzard","sequence":"additional","affiliation":[{"name":"Facult\u00e9 des Sciences M\u00e9dicales et Param\u00e9dicales, Institut de Neurophysiopathologie (INP), UMR 7051, CNRS, Aix Marseille Universit\u00e9, 13005 Marseille, France"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,11,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1858","DOI":"10.1073\/pnas.72.5.1858","article-title":"A Protein Factor Essential for Microtubule Assembly","volume":"72","author":"Weingarten","year":"1975","journal-title":"Proc.
