However while Org 27569 increases the ability of CB1 agonists to bind to the receptor, it decreases their efficacy at stimulating second messenger signalling once bound, and so in practice behaves as an insurmountable antagonist of CB1 receptor function.
Međutim dok Org 27569 povećava sposobnost CB1 agonista da se veži za receptor, on umanjuje efikasnost stimulacije signalizacije sekundarnim glasnikom, tako da se u praksi ponaša kao nepremostiv antagonist funkcije CB1 receptora.
