Synthesis and biological evaluation of a new class of azole urea compounds as Akt inhibitors with promising anticancer activity in pancreatic cancer models

[Display omitted] •The PI3K/Akt pathway plays a key role in epithelial-mesenchymal transitions and angiogenesis during the tumourigenesis.•A new series of 1,2,3-triazole urea compounds was efficiently synthesized.•Some compounds exhibited marked antiproliferative activity and reduction in cell-migration against PDAC cells.•Kinase activity assays delucidated a mechanism of action involving Akt inhibition. The PI3K/Akt pathway is crucial in numerous cellular functions such as cell growth, survival proliferation and movement in both normal and cancer cells. It plays also a key role in epithelial-mesenchymal transitions and angiogenesis during the tumorigenesis processes. Since many transformative events in cancer are driven by increased PI3K/Akt pathway signaling, Akt is considered a valuable target for developing new therapies against various tumor types, including pancreatic cancer. This is because the PI3K/AKT/mTOR pathway is a key downstream effector of RAS, and RAS activation is the most prominent genetic alteration in pancreatic cancer. Herein we report the synthesis and the biological evaluation of a new series of azole urea compounds that exhibited promising antiproliferative and antimigratory activities against pancreatic cancer cells through an Akt inhibition mechanism. These effects were demonstrated using a variety of assays, including Sulforhodamine B, cell-cycle, wound-healing, and kinase activity, apotposis and ELISA assays. Additionally, the anticancer properties of the most active compound in the series were confirmed in the 3D spheroid model of PATU-T cells.
