DA-6886 is an agonist 5-Hydroxytryptamine receptor 4 (5-HT4). DA-6886 induced relaxation of the rat oesophagus preparation in a 5-HT4 receptor antagonist-sensitive manner. The evaluation of DA-6886 in CHO cells expressing hERG channels revealed that it inhibited hERG channel current with an pIC50 value of 4.3, indicating that the compound was 1000-fold more selective for the 5-HT4 receptor over hERG channels.

In the normal ICR mice, DA-6886 (0.4 and 2mg/kg; oral) resulted in a marked stimulation of colonic transit. In the loperamide-induced constipation mouse model, DA-6886 (2mg/kg) significantly improved the delay of colonic transit. Taken together, DA-6886 is a highly potent and selective 5-HT4 receptor agonist to accelerate colonic transit in mice, which might be a therapeutic agent having a favorable safety profile in the treatment of gastrointestinal motor disorders such as IBS-C and chronic constipation.[1]
