PDB Ligand
Compound class: Synthetic organic
Comment: This is compound 10B in [4] which describes its actions as an Akt (aka protein kinase B) inhibitor.
This compound is a thioridazine derivative. Thioridazine is a well known antipsychotic that acts as an antagonist of dopamine receptor activity. The compound also inhibits the kinase activity of Pim-1 [3] and X-ray crystallography shows the compound binding to the Pim-1 pharmacophore.

Bioactivity Comments
Using recombinant human Akt1 (PKBα) and phosphorylation of downstream GSK-3β as a readout of Akt1 activity, Thimmaiah et al (2005) show that this compound almost completely blocks Akt activity at 5μM (see Figure 6 in the article) [4].
