The synthesis and evaluation of several benzothiazole-based compounds are described in an attempt to identify novel dual-acting 5HT(1A) receptor and SERT inhibitors as new antidepressants. Binding affinities at the 5HT(1A) receptor and the serotonin transporter do not appear to be congruent and other areas of the binding sites would need to be explored in order to improve binding simultaneously at both sites. Compounds 20 and 23 show moderate binding affinity at the 5HT(1A) receptor and the SERT site and thus, have the potential to be further explored as dual-acting agents. In addition, compound 20 binds with low affinity to the dopamine transporter (DAT), the norepinephrine transporter (NET) and 5HT(2C) receptor, which are desirable properties as selectivity for SERT (and not DAT or NET) is associated with an absence of cardiovascular side effects.

Buspirone, a commonly prescribed medication for generalized anxiety disorder (GAD), is gaining attention for its narrow window of side effects such as lack of physical dependence, non-sedative properties as compared to other anxiolytic drugs. Its dose-specific therapeutic effects beyond anxiety highlights its clinical significance. Pharmacologically, buspirone activates serotonin-1A pre-synaptic autoreceptors and post-synaptic heteroreceptors which modulate serotonergic neurotransmission induced behavioral changes such as anxiolytic and nootropic effects.

The serotonergic raphe magnus (RMg) and dorsal raphe (DR) nuclei are crucial pain-regulating structures, which nociceptive activity is shown to be altered in gut pathology, but the underlying neuroplastic changes remain unclear. Considering the importance of 5-HT1A receptors in modulating both pain and raphe neuronal activity, in this study, we aimed to determine whether 5-HT1A-dependent visceral and somatic nociceptive processing within the RMg and DR is modified in postcolitis conditions. In anaesthetised male Wistar rats, healthy control and recovered from TNBS-induced colitis, the microelectrode recordings of RMg and DR neuron responses to noxious colorectal distension (CRD) or tail squeezing (TS) were performed prior and after intravenous administration of 5-HT1A agonist, buspirone.

Major depressive disorder (MDD) is among the most common mental disorders worldwide and is characterized by dysregulated reward processing associated with anhedonia. Selective serotonin reuptake inhibitors (SSRIs) are the first-line treatment for MDD; however, their onset of action is delayed. Recent reports have shown that serotonin neurons in the dorsal raphe nucleus (DRN) are activated by rewards and play a vital role in reward processing.

Female sexual behavior is a naturally rewarding activity that plays an important role in reproduction and species survival. For female rats, regulating the timing of sexual interactions is essential for optimizing mating satisfaction and enhancing the physiological conditions needed for successful fertilization. So far, traditional research on female sexual behavior has relied on a limited set of behavioral parameters, which has certain shortcomings.
