Experimental validation of the prediction model for the serotonin transporter (SERT). (a) Structure of CHEMBL1377753 (1). (b) 1 inhibited the substrate uptake of SERT. The specific uptake of the fluorescent substrate for SERT was measured in the absence or presence of ligands in cells expressing human SERT. The specific uptake was normalized to the value in the absence of ligands. The data represent the mean ± s.e.m. n = 4 biological replicates in two independent experiments. (c,d) Administration of 1 induced antidepressant-like effects in mice. After intraperitoneal injection of 1 (1, 10 mg/kg), the immobility duration in the tail suspension test (c) or travelled distance in the open field test (d) was measured. (c) 1 significantly decreased the immobility duration. The data represent the mean ± s.e.m. One-way ANOVA was performed; F(2,19) = 3.64, P = 0.046. Dunnett’s multiple comparisons test *P < 0.05 vs. the saline group. n = 7–8 mice per group. (d) 1 did not significantly affect the travelled distance. The data represent the mean ± s.e.m. One-way ANOVA; F(2,15) = 0.41, P = 0.67. n = 6 mice per group.
