CID-755673 is a potent and selective cell-active small molecule inhibitor for PKD with an IC50 of 182 nM and exhibits selective PKD1 inhibition when compared with AKT, PLK1, CAK, CAMKIIα, and PKC isoforms.

1-Naphthyl PP1 is a selective inhibitor of src family kinases v-Src and c-Fyn as well as the tyrosine kinase c-Abl (IC50 values are 1.0, 0.6, 0.6, 18 and 22 μM for v-Src, c-Fyn, c-Abl, CDK2 and CAMK II respectively).

kb NB 142-70 is a selective protein kinase D (PKD) inhibitor (IC50 values are 28.3, 58.7 and 53.2 nM for PKD1, 2 and 3 respectively).

CID-2011756 is a cell-active ATP competitive and specific PKD1 inhibitor that inhibits phorbol ester-induced endogenous PKD1 activation in LNCaP prostate cancer cells.

CRT0066101 reduces BrdU incorporation, increases apoptosis, blocks neurotensin (NT)-induced PKD1/2 activation, reduces NT-induced PKD-mediated Hsp27 phosphorylation, attenuates PKD1-mediated NF-κB activation, and abrogates expression of NF-κB-dependent-dependent proliferative and pro-survival proteins.
