Synthesis and monoamine transporter affinity of 3α-arylmethoxy-3β-arylnortropanes
摘要:
A series of 3-arylnortrop-2-enes and 3 alpha-arylmethoxy-3 beta-arylnortropanes were synthesized and evaluated for binding affinity at monoamine transporters. The 3-(3,4-dichlorophenyl)nortrop-2-ene (6e) exhibited high affinity for the SERT (K-i = 0.3 nM). The 3 alpha-arylmethoxy-3 beta-arylnortropanes were generally SERT selective with the 3 alpha-(3,4-dichlorophenylmethoxy)-3 beta phenylnortrop-2-ene (7c) possessing subnanomolar potency (K-i = 0.061 nM). However, 3 alpha-(3,4-dichlorophenylmethoxy)-3 beta-phenylnortrop-2-ene (7b) exhibited high affinity at all three transporters [(DAT K-i = 22 nM), (SERT K-i = 6 nM) and (NET K-i = 101 nM)].
