PB 28 dihydrochloride
Chemical Name: 1-Cyclohexyl-4-[3-(1,2,3,4-tetrahydro-5-methoxy-1-naphthalenyl)propyl]piperazine dihydrochloride
Biological ActivityPB 28 dihydrochloride is a high affinity σ2 receptor agonist (Ki values are 0.8 and 15.2 nM for σ2 and σ1 receptors respectively) that displays minimal affinity at other receptors. Inhibits electrically evoked twitch in guinea pig bladder and ileum (EC50 values are 2.62 and 3.96 μM respectively). Displays antiproliferative and cytotoxic effects in SK-N-SH neuroblastoma and C6 glioma cells.
