A series of novel 5-benzylated 4-oxo-3,4-dihydro-5H-pyridazino[4,5-b]indoles was synthesized through a newly developed approach. All these compounds were evaluated against DYRK1A, CDK5 and PI3K alpha and showed promising inhibitory activities against PI3K alpha, with most IC50 values in the micromolar range. Among them, compound 18 was strongly considered as the most interesting compound with an IC50 value of 0.091 mu M. This series exhibited also significant anti-proliferative effects in various human cancer cell lines including those resulting in activation of the PI3K pathway. (C) 2012 Elsevier Masson SAS.
