Alizadeh Pahlavani H. Possible role of exercise therapy on depression: Effector neurotransmitters as key players. Behav Brain Res 2024; 459:114791. [PMID: 38048912 DOI: 10.1016/j.bbr.2023.114791] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2023] [Revised: 11/23/2023] [Accepted: 11/29/2023] [Indexed: 12/06/2023]
Abstract
About 280 million people suffer from depression as the most common neurological disorder and the most common cause of death worldwide. Exercise with serotonin released in the brain by the 5-HT3-IGF-1 mechanism can lead to antidepressant effects. Swimming exercise has antidepressant effects by increasing the sensitivity of serotonin 5-HT2 receptors and postsynaptic 5-HT1A receptors, increasing 5-HT and 5HIAA levels, increasing TPH and serotonin, and decreasing inflammatory levels of IFN-γ and TNF-α. Anaerobic and aerobic exercises increase beta-endorphin, enkephalin, and dynorphin and have antidepressant effects. Exercise by increasing dopamine, D1R, and D2R leads to the expression of BDNF and activation of TrkB and has antidepressant behavior. Exercise leads to a significant increase in GABAAR (γ2 and α2 subunits) and reduces neurodegenerative disorders caused by GABA imbalance through anti-inflammatory pathways. By increasing glutamate and PGC1α and reducing glutamatergic neurotoxicity, exercise enhances neurogenesis and synaptogenesis and prevents neurodegeneration and the onset of depression. Irisin release during exercise shows an important role in depression by increasing dopamine, BDNF, NGF, and IGF-1 and decreasing inflammatory mediators such as IL-6 and IL-1β. In addition, exercise-induced orexin and NPY can increase hippocampal neurogenesis and relieve depression. After exercise, the tryptophan to large neutral amino acids (TRP/LNAA) ratio and the tryptophan to branched-chain amino acids (BCAA) ratio increase, which may have antidepressant effects. The expression of M5 receptor and nAChR α7 increases after exercise and significantly increases dopamine and acetylcholine and ameliorates depression. It appears that during exercise, muscarinic receptors can reduce depression through dopamine in the absence of acetylcholine. Therefore, exercise can be used to reduce depression by affecting neurotransmitters, neuromodulators, cytokines, and/or neurotrophins.

Abstract
Alzheimer's disease (AD), a persistent neurological dysfunction, has an increasing prevalence with the aging of the world and seriously threatens the health of the elderly. Although there is currently no effective treatment for AD, researchers have not given up, and are committed to exploring the pathogenesis of AD and possible therapeutic drugs. Natural products have attracted considerable attention owing to their unique advantages. One molecule can interact with multiple AD-related targets, thus having the potential to be developed in a multi-target drug. In addition, they are amenable to structural modifications to increase interaction and decrease toxicity. Therefore, natural products and their derivatives that ameliorate pathological changes in AD should be intensively and extensively studied. This review mainly presents research on natural products and their derivatives for the treatment of AD.

Prog Neuropsychopharmacol Biol Psychiatry 2023; 123:110693. [PMID: 36509251 DOI: 10.1016/j.pnpbp.2022.110693] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/04/2022] [Revised: 12/05/2022] [Accepted: 12/08/2022] [Indexed: 12/14/2022]
Abstract
Depression is the most prevalent and devastating neuropsychiatric disorder. There are several conventional antidepressants used for the treatment of depression. But due to their undesired adverse effects, patient compliance is very poor. Thus, developing novel medications for the treatment of depression is a critical strategic priority for meeting therapeutic demands. Current research is looking for alternatives to traditional antidepressants to reduce undesired side effects and increase efficacy. Phytoconstituents provide a wide research range in antidepressant treatments. In the present article, we have conducted a comprehensive assessment of neurological evidence, which supports the usefulness of phytoconstituents in the treatment of the depressive disorder. Secondary plant metabolites including alkaloids, polyphenols, glycosides, saponins, and terpenoids were found to exhibit antidepressant action. Most of the phytoconstituents were found to mediate their antidepressant effect through the upregulation of brain-derived neurotrophic factor (BDNF), serotonin, noradrenaline, and dopamine. Some were also found to exert antidepressant effects by inhibiting the monoamine oxidase (MAO) activity and hypothalamic-pituitary-adrenal (HPA) axis overactivity.

Abstract
Acetylcholine is an excitatory neurotransmitter that modulates synaptic plasticity and communication, and it is essential for learning and memory processes. This neurotransmitter is hydrolyzed by acetylcholinesterase (AChE), which plays other cellular roles in processes such as inflammation and oxidative stress. Ion pumps, such as Na+/K+-ATPase and Ca2+-ATPase, are highly expressed channels that derive energy for their functions from ATP hydrolysis. Impairment of the cholinergic system and ion pumps is associated with neuropsychiatric diseases. Major depressive disorder (MDD) is an example of a complex disease with high morbidity and a heterogenous etiology. Polyphenols have been investigated for their therapeutic effects, and tannic acid (TA) has been reported to show neuroprotective and antidepressant-like activities. Animal models of depression-like behavior, such as lipopolysaccharide (LPS)-induced models of depression, are useful for investigating the pathophysiology of MDD. In this context, effects of TA were evaluated in an LPS-induced mouse model of depression-like behavior. Animals received TA for 7 days, and on the last day of treatment, LPS (830 μg/kg) was administered intraperitoneally. In vitro exposure of healthy brain to TA decreased the AChE activity. Additionally, this enzyme activity was decreased in cerebral cortex of LPS-treated mice. LPS injection increased the activity of Ca2+-ATPase in the cerebral cortex but decreased the enzyme activity in the hippocampus. LPS administration decreased Na+/K+-ATPase activity in the cerebral cortex, hippocampus, and striatum; however, TA administration prevented these changes. In conclusion, tannins may affect Na+/K+-ATPase and Ca2+-ATPase activities, which is interesting in the context of MDD.

Abstract
Sarsasapogenin-AA13(AA13), a sarsasapogenin derivative, exhibited good neuroprotective and anti-inflammatory activities in vitro and therapeutic effects on learning and memory dysfunction in amyloid-β-injected mice. A sensitive UPLC-MS/MS method was developed and validated to quantitatively determine AA13 in rat plasma and was further applied to evaluate the pharmacokinetic behaviour of AA13 in rats that were administered AA13 intravenously and orally. This method was validated to exhibit excellent linearity in the concentration range of 1-1000 ng/mL. The lower limit of quantification was 1 ng/mL for AA13 in rat plasma. Intra-day accuracy for AA13 was in the range of 90-114%, and inter-day accuracy was in the range of 97-103 %. The relative standard deviation of intra-day and inter-day assay was less than 15%. After a single oral administration of AA13 at the dose of 25 mg/kg, Cmax of AA13 was 1266.4 ± 316.1 ng/mL. AUC0-48 h was 6928.5 ± 1990.1 h·ng/mL, and t1/2 was 10.2 ± 0.8 h. Under intravenous administration of AA13 at a dosage of 250 μg/kg, AUC0-48 h was 785.7 ± 103.3 h⋅ng/mL, and t1/2 was 20.8 ± 7.2 h. Based on the results, oral bioavailability (F %) of AA13 in rats at 25 mg/kg was 8.82 %.

Abstract
Sarsasapogenin derivative 5n (SGD 5n) is a new compound with potent antitumor efficacy, but the low solubility severely affects its absorption and bioavailability. Therefore, the SGD 5n-loaded mPEG-PLGA block copolymer micelles were developed to improve the value of SGD 5n in clinical application. The polymeric micelles were prepared by an organic solvent evaporation method, and the encapsulation efficiency (EE), drug loading (DL), critical micelle concentrations (CMC), morphology, particle size, and zeta potential were determined. The cytotoxicity was examined by the MTT assay, and the cellular uptake study was performed by confocal laser scanning microscopy. A model of tumor-bearing mouse was established to study the antitumor activity in vivo. The results demonstrated that the particle size of the prepared micelle was 124.6 ± 9.6 nm, the encapsulation efficiency was 82.0 ± 2.9%, and the drug loading was 8.3 ± 0.4%. The results of cytotoxicity and cellular uptake demonstrated that the SGD 5n-loaded micelles could efficiently enter tumor cells, and the cellular uptake of SGD 5n presented concentration and time dependence. This study demonstrated that the prepared SGD 5n-loaded polymeric micelles had significant antitumor activity and provided a basis for clinical development of new compound SGD 5n.

Abstract
A sarsasapogenin derivative, sarsasapogenin-AA22 (AA22), with cyclobutylamine at the 3-hydroxyl position of sarsasapogenin, has great neuroprotective activity in PC12 cells and NO production inhibitory activity in RAW264.7 cell lines. A method was developed to determine AA22 in rat plasma which was further applied to evaluate the pharmacokinetics of AA22 after taking a single dose of AA22. Liquid chromatography tandem mass spectrometry was used in the method, while diosgenin was used as internal standard. A simple protein precipitation based on acetonitrile was utilized. A simple sample cleanup promoted the throughput of the method considerably. The method was validated over the range of 1-1000 ng/mL with a correlation coefficient > 0.99. The lower limit of quantification was 1 ng/mL for AA22 in plasma. Intra- and inter-day accuracies for AA22 were 92-111 and 100-103%, respectively, and the inter-day precision was <15%. After a single oral dose of 25 mg/kg of AA22, the mean peak plasma concentration of AA22 was 2114 ± 362 ng/mL at 6 h. The area under the plasma concentration-time curve was 196,098 ± 69,375 h ng/mL, and the elimination half-life was 8.7 ± 2.2 h.

Abstract
Sarsasapogenin, a kind of mainly effective component of Anemarrhena asphodeloides Bunge, possesses good antitumor properties. Two series of new sarsasapogenin derivatives were synthesized and evaluated for their cytotoxicities against three human cancer cell lines (HepG2, A549, MCF-7) using the MTT assay. The structure-activity relationship revealed that the N, N-dimethylamino, pyrrolidinyl, and imidazolyl substituted at the C26 position could increase the antitumor efficacy of the 3-oxo sarsasapogenin series of compounds. Compound 4c with pyrrolidinyl substituted at the C26 position exhibited the greatest cytotoxic activity against MCF-7 cell line (IC50 = 10.66 μM), which was 4.3-fold more potent than sarsasapogenin. Action mechanism investigations showed that 4c could inhibit the colony formation and induce the apoptosis of MCF-7 cells. Further researches showed that a decrease in mitochondrial membrane potential and increases in the expression level of cleaved-PARP and the ratio of Bax/Bcl-2 were observed in MCF-7 cells after treatment with 4c, suggesting that the mitochondrial pathway was involved in the 4c-mediated apoptosis. These results show that compound 4c may serve as a lead for further optimization.
