DA-6886 is an antagonist of the 5-HT4 receptor, discovered by the Korean Dong-A ST Research Institute. The drug binds with high activity and selectivity to human 5-HT4 receptor splice variants, with mean pKi of 7.1, 7.5 and 7.9 for the human 5-HT4a, 5-HT4b, and 5-HT4d, respectively. DA-886 induced relaxation of the rat esophagus preparation in a 5-HT4 receptor antagonist-sensitive manner. In the normal ICR mice, oral administration of the drug at 0.4 and 2 mg/kg resulted in a marked stimulation of colonic transit. DA-6886 was investigated in phase I clinical trial for the treatment of Irritable Bowel Syndrome.

Official Title: A Phase I, Dose Block-randomized, Double-blind, Placebo-controlled, Single/Multiple Dosing, Dose Escalation Clinical Trial With Open-labelled Food Effect Study of Single Dose to Investigate the Safety, Tolerability and Pharmacokinetics of DA-6886 After Oral Administration in Healthy Male Subjects
Purpose: DA-6886_IBS_I is a phase I, dose block-randomized, double-blind, placebo-controlled, single/multiple dosing, dose escalation clinical trial with open-labelled food effect study of single dose to investigate the safety, tolerability and pharmacokinetics of DA-6886 after oral administration in healthy male subjects.

ACTIVE MOIETY |
DA-6886 exhibited high affinity and selectivity to human 5-HT4 receptor splice variants, with mean pKi of 7.1, 7.5, 7.9 for the human 5-HT4a, 5-HT4b and 5-HT4d, respectively. By contrast, DA-6886 did not show significant affinity for several receptors including dopamine D2 receptor, other 5-HT receptors except for 5-HT2B receptor (pKi value of 6.2). The affinity for 5-HT4 receptor was translated into functional agonist activity in Cos-7 cells expressing 5-HT4 receptor splice variants. Furthermore, DA-6886 induced relaxation of the rat oesophagus preparation (pEC50 value of 7.4) 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, oral administration of DA-6886 (0.4 and 2mg/kg) resulted in marked stimulation of colonic transit.
