Description |
PS315, a derivative of PS48 (HY-15967), is an allosteric PKC inhibitor by binding to the PIF-pocket of aPKC and inducing a displacement of the active site residue Lys111. PS315 inhibits the full-length and catalytic domain constructs of PKCζ (IC50=10 μM) and PKCη (IC50=30 μM). PS315 has anti-cancer activity[1].

In Vitro |
Preincubation of U937 cells with 5 μM PS315 inhibits TNF-α induced NF-κB activation by 74%, whereas complete inhibition is observed with 10 μM PS315[1]. The small allosteric inhibitor PS315 and the N-terminal region of aPKC both act directly on the PIF-pocket on-off switch. PS315, binding at the PIF-pocket, induces a displacement of the active site residue Lys111, thereby inhibiting the activity of aPKCs by allosterically affecting the catalytic mechanism of the kinase[1].
