The Effect of the Stress Induced by Hydrogen Peroxide and Corticosterone on Tryptophan Metabolism, Using Human Neuroblastoma Cell Line (SH-SY5Y). Int J Mol Sci 2023; 24:ijms24054389. [PMID: 36901819 PMCID: PMC10001894 DOI: 10.3390/ijms24054389] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2023] [Revised: 02/18/2023] [Accepted: 02/21/2023] [Indexed: 02/25/2023] Open
Abstract
L-tryptophan (L-Trp) is an important amino acid in several physiological mechanisms, being metabolized into two important pathways: the kynurenine and the serotonin (5-HT) pathways. It is important in processes such as mood and stress response, the 5-HT pathway begins with the conversion of L-Trp to 5-hydroxytryptophan (5-HTP), that is metabolized into 5-HT, converted to melatonin or to 5-hydroxyindoleacetic acid (5-HIAA). Disturbances in this pathway are reported to be connected with oxidative stress and glucocorticoid-induced stress, are important to explore. Thus, our study aimed to understand the role of hydrogen peroxide (H2O2) and corticosterone (CORT)-induced stress on the serotonergic pathway of L-Trp metabolism, and on SH-SY5Y cells, focusing on the study of L-Trp, 5-HTP, 5-HT, and 5-HIAA in combination with H2O2 or CORT. We evaluated the effect of these combinations on cellular viability, morphology, and on the extracellular levels of the metabolites. The data obtained highlighted the different ways that stress induction led to different extracellular medium concentration of the studied metabolites. These distinct chemical transformations did not lead to differences in cell morphology/viability. Additionally, serotonin may be the most sensitive metabolite to the exposure to the different stress inducers, being more promissory to study conditions associated with cellular stress.

Abstract
Depression is the single largest contributor to global disability with a huge economic and social burden on the world. There are a number of antidepressant drugs on the market, but treatment-resistant depression and relapse of depression in a large number of patients have increased problems for clinicians. One peculiarity observed in most of the marketed antidepressants is the presence of a piperazine substructure. Although piperazine is also used in the optimization of other pharmacological agents, it is almost extensively used for the development of novel antidepressants. One common understanding is that this is due to its favorable CNS pharmacokinetic profile; however, in the case of antidepressants, piperazine plays a much bigger role and is involved in specific binding conformations of these agents. Therefore, in this review, a critical analysis of the significance of the piperazine moiety in the development of antidepressants has been performed. An overview of current developments in the designing and synthesis of piperazine-based antidepressants (2015 onwards) along with SAR studies is also provided. The various piperazine-based therapeutic agents in early- or late-phase human testing for depression are also discussed. The preclinical compounds discussed in this review will help researchers understand how piperazine actually influences the design and development of novel antidepressant compounds. The SAR studies discussed will provide crucial clues about the structural features and optimizations required to enhance the efficacy and potency of piperazine-based antidepressants.

Abstract
Prostate cancer is difficult to treat if it metastasizes to other organs. The development of prostate cancer independent of androgen is closely related to the action of neuroendocrine products. Serotonin promotes cell growth in various cancers, and antagonists for serotonin receptors are known to inhibit proliferation and induce cell death in various carcinomas. However, little is known about how antagonists for serotonin receptor function in prostate cancer. We verified apoptotic cell death in prostate cancer cell lines after treatment with methiothepin mesylate (MET), an antagonist for serotonin receptor 5-HT1. MET induced hydrogen peroxide (H2O2) production and mitochondrial Ca2+ overload. Moreover, MET induced changes in the expression of proteins associated with endoplasmic reticulum stress, autophagy, and mitochondrial membrane potential. MET also promoted phosphorylation of JNK, which induced cell death mediated by oxidant production, as evidenced by the JNK inhibitor and oxidant scavenger. Finally, MET has the potential to prevent metastasis by inhibiting the migration of prostate cancer cells. Thus, we show that MET is a potentially novel anticancer agent that can suppress the development of prostate cancer caused by neuroendocrine differentiation.
