A series of isoindoline derivatives were designed, synthesized, and evaluated for their double inhibitory activities. All of them were new compounds, and their structures were confirmed by 1H NMR and HR-MS. Preliminary in vitro pharmacological tests showed that all compounds exhibited 5-HT or NE reuptake inhibition activity. Among the tested compounds, compound I-3 exhibited potent inhibitory activity against 5-HT and NE reuptake in vitro, and exhibited potent antidepressant activity in vivo. These compounds designed can be further optimized for finding more potent 5-HT/NE dual reuptake inhibitors and antidepressant candidates as well.

BACKGROUND/AIMS: A large number of studies have shown that function constipation (FC) has an extremely high incidence of mental and psychological disorders. Cranial electrotherapy stimulation (CES) was applied to the treatment of psychological disorders such as anxiety and depression. We explored the effects of CES combined with biofeedback therapy (BFT) on the psychological state, clinical symptoms, and anorectal function in patients with FC. METHODS: A total of 74 patients with FC were randomly divided into 2 groups. The control group received BFT. CES combined with BFT was carried out in the experiment group. All patients were assessed using the self-rating anxiety scale (SAS), self-rating depression scale (SDS), and Wexner constipation score at baseline and the end of each course. Anorectal manometry and balloon expulsion tests were performed before and after treatment. RESULTS: After treatment, the participants in the experiment group had significantly lower score SAS, SDS, and Wexner constipation scores than the control group (all P < 0.05). The number of successful expulsion in the experiment group was larger than the control group (P = 0.016). CONCLUSIONS: CES combined with BFT was effective in improving the psychological status of anxiety, depression, and bowel symptoms in patients with FC.
