Addition of the synthetic compound (1 nM) occurred 15 min prior to assessment of Cai2+ release evoked by increasing concentrations of 5-HT (vehicle, 10−11 to 10−5 M) in h5-HT2BR-CHO cells. Data are presented as maximal 5-HT-induced Cai2+ release (Emax).
p < 0.05. Comparisons between means for Emax were conducted with an unpaired t test with Welch’s correction (GraphPad Prism). All statistical analyses were conducted with an experiment-wise error rate of α = 0.05.
