Inhibitors of PP2B (calcineurin) will only be mentioned in passing, except to state that, in our hands, cypermethrin, deltamethrin, and fenvalerate, which are sold as potent inhibitors of PP2B, do not inhibit the catalytic activity of PP2B.

DHA-induced apoptosis was effectively inhibited by tautomycin and cypermethrin at concentrations that affect protein phosphatase 1 (PP1) and protein phosphatase 2B (PP2B) activities, respectively, implying a role for these phosphatases in the apoptotic pathway.

However, combinations of FK-520 (5 microM) and okadaic acid (100 nM) caused tau mobility shifts similar to those seen after 10 microM okadaic acid treatment; similar results were seen using the calcineurin-selective inhibitor cypermethrin.

1315545 Enan E, Matsumura F: Specific inhibition of calcineurin by type II synthetic pyrethroid insecticides. Biochem Pharmacol. 1992 Apr 15;43(8):1777-84.

The inhibitory action of synthetic pyrethroids and some chlorinated hydrocarbon insecticides on the neural calcium-calmodulin-dependent protein phosphatase, calcineurin, was studied using one radiotracer and two colorimetric methods.
It was found that all insecticidal Type II pyrethroids (cypermethrin, deltamethrin and fenvalerate) are potent inhibitors of isolated calcineurin from bovine brain.

In the present study, the role of protein phosphatases in the adrenergic regulation of rat pineal AA-NAT was investigated using specific inhibitors.
In cultured pineals, the serine/threonine phosphatase type 1 and type 2A inhibitors okadaic acid and calyculin A significantly decreased adrenergically or cAMP-induced AA-NAT activity, whereas the serine/threonine phosphatase type 2B inhibitor cypermethrin and tyrosine phosphatase inhibitor dephostatin were ineffective.

Calcineurin, a Ca2+/calmodulin dependent protein phosphatase, regulates Ca2+-dependent processes in a wide variety of cells.

The involvement of protein phosphatases in transmission of the PRL signal in early luteal cells in pigs is also suggested.
In addition, treatments included: PKC inhibitors--staurosporine and chelerythrine chloride; tyrosine kinase inhibitors--genistein and tyrphostin; serine-threonine phosphatase inhibitors--okadaic acid, cantharidin (inhibitors of PP1/2A) and cypermethrin (inhibitor of PP2B); and tyrosine phosphatase inhibitor--sodium orthovanadate.

Neither the PKA inhibitor H89 (1 micro M) nor the protein phosphatase inhibitors okadaic acid (500 nM) or cypermethrin (1 micro M) prevented or mimicked the InsP5,6-induced stimulation of Ba2+ current.
However, InsP5 or InsP6 could mimic some effects of protein phosphatase inhibitor so as to extend after washing-out forskolin the stimulatory effects of the adenylyl cyclase activator on Ba2+ current.

The ability of cAMP to translocate and dephosphorylate NTCP is, in part, dependent on cAMP-mediated increases in cytosolic Ca2+ concentration ([Ca2+]), indicating that a Ca2+/calmodulin-dependent protein phosphatase (PP2B) may be involved.
Thus we studied the role of PP2B using the inhibitor cypermethrin (CM).

The goal of this study was to determine if protein phosphatases (PPs) and intracellular calcium mediate reductions in turtle cortical neuron whole-cell NMDAR currents during anoxia, thereby preventing ECD.
However, cypermethrin, an inhibitor of the Ca (2+)/calmodulin-dependent PP2B (calcineurin), abolished the anoxic decrease in NMDAR activity at 20, but not 40 min suggesting that this phosphatase might play an early role in attenuating NMDAR activity during anoxia.

The ability of selective protein phosphatase inhibitors to modulate autoreceptor-mediated potentiation of dopamine uptake was also examined.
Pretreatment with protein phosphatase 2B (deltamethrin, cypermethrin) or protein phosphatase 1 (tautomycin) inhibitors attenuated basal and quinpirole-potentiated dopamine uptake in ovariectomized but not estrogen-primed tissue.

Cypermethrin, a PP2B phosphatase inhibitor, but not okadaic acid, a PP1/PP2A inhibitor, prolonged the effect of CALCA on P-S (1105), whereas the reverse was the case for the oxytocin-stimulated increase in P-S (1105).

Novelty exploration-induced reversal of stress effects was prevented when the animals were given the NMDA receptor antagonist D-(-)-2-amino-5-phosphonopentanoic acid, the cholinergic antagonist atropine and the protein phosphatase (PP) 2B inhibitors cyclosporin A and cypermethrin, but not the alpha1-adrenergic antagonist prazosin, the beta-adrenergic antagonist propranolol or the PP1/2A inhibitor okadaic acid, respectively before being subjected to the novel environment.
