Description

Anpirtoline [D 16949] is a dichloropyridine derivative with antinociceptive and antidepressant activity. Anpirtoline has been described as an agonist at 5-HT1B and 5-HT1D receptors with a relatively high potency. It also acts as an agonist at 5-HT1A receptors, but has a lower potency than at the 5-HT1B sites. In addition, Anpirtoline acts as an antagonist at 5-HT3 receptors. The drug was in phase I clinical trials with ASTA Medica in Germany for the treatment of pain and depression, but development was suspended.

Sample Use Guides

In Vivo Use Guide
The pain relieving properties of imipramine (100 mg orally), tramadol (150 mg orally), and anpirtoline (60 mg orally) were compared in 16 healthy subjects in a cross-over, double-blind, randomized, and placebo-controlled study.
Route of Administration: Oral
In Vitro Use Guide
Binding assays with rat brain membranes have shown that anpirtoline bound with a much higher affinity to 5-HT1B receptor (Ki = 28 nM) than to 5-HT1A (Ki = 150 nM) and 5-HT2 (Ki = 1.49 uM) receptors.
