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

It was found that all insecticidal Type II pyrethroids (cypermethrin, deltamethrin and fenvalerate) are potent inhibitors of isolated calcineurin from bovine brain.

The type II pyrethroid insecticides cis-cypermethrin (c-Cyp), trans-cypermethrin, deltamethrin (Delt), and fenvalerate A alpha (Fen), as well as the type I pyrethroid insecticides cis- and trans-permethrin and S-bioallethrin, were unable to inhibit the phosphatase activity of purified calcineurin under conditions of maximal activation by Ca2+ and calmodulin.

Inhibition of the Ca++/calmodulin-dependent phosphatase calcineurin with fenvalerate also prevented rundown of the response to GABA.

The role of calcineurin in CyA- or FK506-induced growth inhibition was investigated using the synthetic pyrethroid insecticides: cypermethrin, deltamethrin and fenvalerate, which are known calcineurin inhibitors.

The Cs A effect on Na+ transport could be caused by an inhibition of a Ca2+/calmodulin-dependent protein phosphatase, i.e. calcineurin, since: a) it is mimicked by another inhibitor of calcineurin, i.e. fenvalerate: b) the action of Cs A and fenvalerate on SCC are decreased by the calmodulin inhibitor W7.

Similarly, blocking calmodulin activation with calmidazolium or blocking calcineurin with fenvalerate did not influence the extent of Ca (2+)-dependent inactivation after photolysis.

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.
