Pure human CEs (hCE-1 and hCE-2), a rabbit CE (rCE), and two rat CEs (Hydrolases A and B) were used to study the hydrolytic metabolism of the following pyrethroids: 1Rtrans-resmethrin (bioresmethrin), 1RStrans-permethrin, and 1RScis-permethrin. hCE-1 and hCE-2 hydrolyzed trans-permethrin 8- and 28-fold more efficiently than cis-permethrin (when k (cat)/K (m) values were compared), respectively.

In addition, oxysterol-mediated inhibition of CES1 activity was demonstrated by pretreatment of human liver homogenates or intact THP1 cells with exogenous 27-HC, which resulted in significantly reduced hydrolysis of the pyrethroid insecticide bioresmethrin, a CES1-specific xenobiotic substrate.
Two major isoforms of human carboxylesterases (CEs) are found in metabolically active tissues, CES1 and CES2.

The major esterase in human intestine is carboxylesterase 2 (hCE2).
We found that the pyrethroid trans-permethrin is effectively hydrolyzed by a sample of pooled human intestinal microsomes (5 individuals), while deltamethrin and bioresmethrin are not.
