Off-Target Selectivity Assesments

Potency assay, off target (cells): CPS-021 effectively decreased the phosphorylation of PAK4 in A549 and MDA-MB-231 cell lines. CPS-021 performed excellent selectivity against PAK5, as only the relative abundance of pPAK4 rather than pPAK5 decreased in both cell lines.

Potency assay, off target (cells): CPS-021-Incubated A549 cells were checked via Proteomic analysis to identify up- and down- regulated proteins (after 14 h coincubation of 5 μM CPS-021): 201 differential proteins were identified. Among them, 57 proteins were significantly upregulated, and 144 proteins were downregulated.
