Subtype-selective nicotinic receptor antagonists: potential as tobacco use cessation agents
2004
Abstract N-n -Alkylpicolinium and N,N ′-alkyl-bis-picolinium analogues were assessed in nicotinic receptor (nAChR) assays. The most potent and subtype-selective analogue, N,N ′-dodecyl-bis-picolinium bromide (bPiDDB), inhibited nAChRs mediating nicotine-evoked [ 3 H]dopamine release (IC 50 =5 nM; I max of 60%), and did not interact with α4β2* or α7* nAChRs. bPiDDB represents the current lead compound for development as a tobacco use cessation agent.
