Polo-like Kinase (PLK)
Polo-like Kinases (PLKs) are a group of highly conserved serine/threonine protein kinases that play a key role in processes such as cell division and checkpoint regulation of mitosis. In mammals, five PLKs (PLK 1-5) encompass diverse roles in centrosome dynamics, spindle formation, intra S-phase and G2/M checkpoints, and DNA damage response.
PLKs are characterized by their Polo-box domain, which mediates protein interactions. They are additionally controlled by phosphorylation, proteolysis, and transcription, depending on the biological context. PLKs are now recognized to link cell division to developmental processes and to function in differentiated cells.

CAP-53194
0 ImagesCat. No.: HY-123702CAS No.: 660817-08-3CAP-53194 is a selective Plk1 inhibitor with potential anticancer activity. CAP-53194 was identified by a high-throughput virtual screening approach using molecular docking, showing 100-fold selectivity for Plk1 over Plk2-4 and other cell cycle kinases. CAP-53194 is able to effectively exploit subtle differences between the binding sites of Plk1 and other Ser/Thr kinases, thereby enhancing their inhibitory effects. CAP-53194 meets the Lipinski compound analog criteria and passes other ADMET filters, indicating good compound compatibility. CAP-53194 belongs to a new class of potential Plk1 inhibitors suitable for subsequent compound development and testing.

NL13
0 ImagesCat. No.: HY-162895NL13 is a Polo-like kinase 4 (PLK4) inhibitor with an IC50 value of 2.32 μM. NL13 can inhibit the viability of PC3 and DU145 prostate cancer cells, with IC50 values of 3.51 μM and 2.53 μM, respectively. NL13 can lead to the inactivation of the AKT signaling pathway by downregulating CCNB1/CDK1, inducing G2/M cell cycle arrest, and triggering apoptosis through the cleavage of caspase-9/caspase-3. In prostate cancer mice, NL13 can inhibit tumor growth.
