Deltamethrin | Calcineurin inhibitor; displays neurotrophic activity

Deltamethrin (52918-63-5) is reported to be an inhibitor of calcineurin (PP2B), IC50~100 pM1 but this activity has been disputed2. Markedly enhances the expression of BDNF in cultured rat cortical neurons and displays neurotrophic effects.3 Produces antidepressant-like effects in mice.4 Blocks the spontaneous down-regulation of Nav1.8 sodium channels expressed in Xenopus oocytes.5
