A new series of potential Akt1 inhibitors with indole scaffold were designed and synthesized. The antiproliferative activity against PC-3 cell line and enzyme inhibitory activity against Akt1 were evaluated. Among them, some compounds showed much more potent antiproliferative activity and stronger Akt1 inhibitory activity compared to the positive control of GSK690693. In particular, compound 19b exhibited the most potent inhibitory activity against Akt1 with inhibition rate of 70.3% at a concentration of 10 nm. Furthermore, compound 19b could dose dependently reduce the phosphorylation of the downstream GSK3β protein in the PC-3 cell line and displayed fivefold higher antiproliferative activity against PC-3 cell line with IC50 value of 3.1 ± 0.1 μm than positive control (15.5 ± 0.4 μm). Herein, compound 19b may serve as a promising lead for further optimization and development of novel Akt1 inhibitors based on an indole scaffold. A novel series of indole derivatives targeting the Akt1 were designed and synthesized. Compound 19b exhibited the most potent inhibitory activity against Akt1 with inhibition rate of 70.3% at the concentration of 10 nm and fivefold higher antiproliferative activity against PC-3 cell with IC50 value of 3.1 ± 0.1 μm than positive control (15.5 ± 0.4 μm).
