CPS-021

CPS-021 is a selective PAK4 PROTAC degrader with a DC₅₀ of 50 nM. CPS-021 degrades PAK4 via the ubiquitin-proteasome system. CPS-021 inhibits the migration and invasion of tumor cells, suppresses TGFβ-induced epithelial-mesenchymal transition (EMT) in tumor cells, and can be used in studies related to lung cancer metastasis.
(Pink: PAK4 ligand (HY-174822); Blue: Cereblon ligand (HY-10984); Black: linker).

CPS-021 is a selective PAK4 PROTAC degrader with a DC₅₀ of 50 nM. CPS-021 degrades PAK4 via the ubiquitin-proteasome system. CPS-021 inhibits the migration and invasion of tumor cells, suppresses TGFβ-induced epithelial-mesenchymal transition (EMT) in tumor cells, and can be used in studies related to lung cancer metastasis^[1].

In Vitro

CPS-021 (0.05-15.0 μM; 2-24 h) induces concentration-dependent and time-dependent degradation of PAK4 protein in A549 and MDA-MB-231 cells, without altering the phosphorylation level of PAK5^[1].
CPS-021 inhibits PAK4 kinase activity in a cell-free system, with an IC₅₀ value of 382.7 nM^[1].
CPS-021 (0.6-10 µM) significantly reduces the protein and phosphorylation levels of PAK4 and its downstream target LIMK1 in H1299 cells^[1].
CPS-021 (0.32-20 µM; 72 h) exhibits minimal cytotoxicity and weak antiproliferative activity in A549, MDA-MB-231 and H1299 cells^[1].
CPS-021 (1-10 µM; 24-48 h) inhibits cell wound healing, migration and invasion in a concentration-dependent manner in A549, MDA-MB-231 and H1299 cells^[1].
CPS-021 (0.01-0.64 μM) combined with TGF-β1 (HY-P78213) (5 ng/mL) blocks TGF-β-induced epithelial-mesenchymal transition (EMT) and alters the expression of related markers in A549 cells^[1].
CPS-021 (5 μM; 14 h) exerts significant effects on altering the global proteome profile and regulating signaling pathways such as NOD-like receptors in A549 cells^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
