Perfluorodecalin (PFD) is a chemically and biologically inert biomaterial, hydrophobic and radiolucent, used as artificial blood. Perfluorodecalin enhances bone regeneration and cell viability.

Ro 90-7501 is an amyloid β42 (Aβ42) protofibrillar and TPR-dependent PP5 inhibitor, a novel radiosensitizer for cervical cancer cells, which inhibits ATM phosphorylation, promotes apoptosis, and induces cell-cycle arrest. Ro 90-7501 also exhibits antiviral activity and potential anticancer activity by inhibiting ATM phosphorylation and DNA repair, and by inhibiting HCMV.

Okadaic acid is a potent polyether marine toxin that primarily accumulates in the digestive glands of marine mollusks. It is a highly effective and selective inhibitor of protein phosphatases (PPs). By inhibiting these phosphatases, okadaic acid increases the phosphorylation levels of various proteins, acts as a tumor promoter, and induces tau protein phosphorylation. It can be used to establish models of Alzheimer’s disease and skin cancer.

PP5-IN-1 is a potent and competitive serine/threonine protein phosphatase-5 (PP5) inhibitor with potential anticancer activity that induces apoptosis in cancer cells.

Hydroxy-PP is a powerful inhibitor of CBR1, exhibiting an IC50 value of 0.78 μM, and also strongly inhibits the cytoplasmic tyrosine kinase Fyn with an IC50 value of 5 nM [1].
