Diaryldiamines with Dual Inhibition of the Histamine H3 Receptor and the Norepinephrine Transporter and the Efficacy of 4-(3-(Methylamino)-1-phenylpropyl)-6-(2-(pyrrolidin-1-yl)ethoxy)naphthalen-1-ol in Pain
摘要:
A series of compounds was designed as dual inhibitors of the H-3 receptor and the norepinephrine transporter. Compound 5 (rNET K-i = 14 nM; rH(3)R K-i = 37 nM) was found to be efficacious in a rat model of osteoarthritic pain.

The 10α,20α-bis(4-nitrophenyl)-calix[4]pyrrole 2 can act as a topologically selective protecting group in the O-alkylation and acylation of polyphenolic polycyclic aromatic compounds thanks to the regioselective formation of phenolate-type complexes. Remarkably, the host–guest interaction with the anionic reagents is sufficiently strong and kinetically slow to produce a high degree of selectivity.
