In Vitro	5-HT4 antagonist 1 (compound 6b) is a 5-HT4 receptor antagonist with a pKi of 9.6.
In Vivo	5-HT4 antagonist 1 (compound 6b) demonstrates good exposure and prolongs t1/2 in other species, including the mouse (t1/2 7 h), rat (t1/2 12 h) and mini-pig (t1/2 21 h). In Phase I clinical trial, it is found that 5-HT4 antagonist 1 has good oral bioavailability with a steady state plasma t1/2 of >100 h[1].
