We observed that native PPase activity together with development and molting in vitro of A. suum L3 to L4 were efficiently inhibited in a dose-dependent manner by imidodiphosphate and sodium fluoride, which are potent inhibitor of both soluble- and membrane-bound H+-PPases.

However, prior exposure to these ions afforded striking protection against inhibition by sodium fluoride, to which the enzyme was otherwise very sensitive.

In the present study the influence of dephosphorylation by Ser/Thr protein phosphatases (PPases) on tumor cell adhesion was investigated.
Pretreatment of poorly and highly metastatic human HT-29 colon carcinoma cells with the broad-range inhibitors sodium fluoride (NaF) and sodium pyrophosphate (PyroP) resulted in strong reduction in adhesion of HT-29 cells to various ECM components.

Sodium fluoride (NaF) is an anion that has been previously shown to block the moulting process of Ascaris suum larvae.
Enzyme assay and immunochemical data showed an inhibition of the moulting-specific inorganic pyrophosphatase activity by 41% and a decreased expression in NaF-treated larvae, indicating its significance in the moulting process.
