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)napht
A series of compounds was designed as dual inhibitors of the H3 receptor and the norepinephrine transporter. Compound 5 (rNET Ki = 14 nM; rH3R Ki = 37 nM) was found to be efficacious in a rat model of osteoarthritic pain.
