AstraZeneca (formerly Astra) is developing robalzotan (NAD-299, AZD-7371), a 5-HT1A antagonist, for the potential treatment of depression and anxiety. The compound has entered phase II trials but was discontinued. Then it investigated for the treatment of irritable bowel syndrome, but the study was prematurely terminated. The same final has expected the development of robalzotan in phase II to treat overactive bladder, this investigation was terminated in July 2005.

In Vitro Use Guide

[3H]NAD-299 (Robalzotan) binding displayed a Kd value of 0.17 nM and a Bmax value of 26.7 pmol/g wet weight of rat hippocampus. Same binding affinity (Kd = 0.16 nM) was found to cloned human 5-HT1A receptors. Addition of the nonhydrolyzable GTP analog guanylylimidodiphosphate had no effect on the binding characteristics of [3H]NAD-299, while it significantly decreased both the affinity and density of receptors labeled with [3H]8-OH-DPAT. The rank order of potency of various compounds to inhibit [3H]NAD-299 binding is consistent with the labeling of 5-HT1A receptors.
