QP5038 is a potent inhibitor of glutaminyl-peptide cyclotransferase-like protein (QPCTL) with IC50 of 3.8 nM, shows promising in vitro and in vivo anti-tumor efficacies.
QP5038 shows a comparable inhibition to QPCT.
QP5038 exhibits dose-dependent inhibition of pGlu-CD47 levels in HEK293T cells with IC50 of 3.3 nM.
QP5038 significantly reduces the binding of human or mouse SIRPα protein to cell surface in HEK293T and tumor cells, blocks the binding of CD47/SIRPα.
QP5038 attenuates the interaction of CD47/SIRPα in a dose-dependent manner with an IC50 value of 8.5 nM in HEK293T cells, which is more potent than PQ912 and SEN177.
QP5038 significantly attenuates CD47 pyroglutamation in various types of cancer cells.
The anti-cancer effect of QP5038 is due to the activation of immune response.
