TDZD-8 (NP 01139) is an inhibitor of GSK-3β, with an IC50 of 2 μM; minimal inhibitory effect observed on CDK1, casein kinase II, PKA and PKC.

CK2 Inhibitor 2, characterized as a potent, selective, and orally active inhibitor of CK2, demonstrates an impressive IC50 value of 0.66 nM. It exhibits high selectivity towards Clk2 with an IC50 of 32.69 nM in comparison to CK2. Furthermore, CK2 Inhibitor 2 has been shown to possess promising antiproliferative and antitumor activities [1].

CK-2-68 is a potent inhibitor of PfNDH2.

CK-666 is a cell-permeable inhibitor of actin-related protein Arp2/3 complex. It binds to the Arp2/3 complex, stabilizes the inactive state of the complex, blocking the movement of the Arp2 and Arp3 subunits into the activated filament-like (short pitch)

CK-869 is an Actin-Related Protein 2/3 (ARP2/3) complex inhibitor(IC50 of 7 μM),and is useful tools for the investigation of the Arp2/3 complex.

CK-636 (CK-0944636), an Arp2/3 complex inhibitor, can inhibit actin polymerization induced by the human (IC50: 4 μM), fission yeast (IC50: 24 μM) and bovine (IC50: 32 μM) Arp2/3 complex, respectively.
