[PMID: 38112520 DOI: 10.1080/03639045.2023.2297238] [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: 07/30/2023] [Accepted: 12/15/2023] [Indexed: 12/21/2023]
Abstract
OBJECTIVE Non-tricyclic antidepressants (non-TCAs) work by preventing the intake of norepinephrine and serotonin. Therefore, the aim of this study was to identify a potent non-TCAs and to develop liposomal formulation, characterize and to determine the drug release study across model of dialysis membrane via in vitro and in silico techniques. METHODS The in silico docking analysis identified venlafaxine (VLF) as the best non-TCAs with the depressant targets (PDB ID: 3PBL and 4BVN). VLF-loaded liposomal formulation was prepared by the thin-film hydration technique and characterized by physicochemical properties, including entrapment efficacy, in vitro drug release, particle size analysis, and FTIR. Moreover, this article also compares VLF and VLF-loaded with liposome carriers (LPs) based on nose-to-brain drug delivery approaches to treating depression. RESULTS Drug release profiles of the optimal liposomal formulation of VLF-LPs were examined in the high entrapment efficiency 94.13 ± 1.20% was attained at 224 nm, composed of spherical particles having a mean particle size of 191 ± 2.0 nm, a polydispersity index of 0.281 ± 0.06 and zeta potential of -20.3 mV. The best formulation of VLF-LPs was more effective than oral VLF treatment, as shown by the in vitro drug release data. CONCLUSION The results show that the VLF-LPs formulation is a promising potential platform for application in nose-to-brain drug delivery. Thus, highlighting the robustness of the intranasal drug delivery system with enhanced pharmaceutical properties, efficacy, and bioavailability for the anti-depression effect.

Abstract
The toxic effects of venlafaxine (VLX) on aquatic organisms have already been verified and therefore are a proven matter of concern. Herein, we evaluated zebrafish embryos/adults after acute exposure to VLX. Embryos/larvae were exposed to different concentrations of VLX (100-1000 mg/L; 1.33 as a dilution factor), to evaluate mortality/developmental changos and to analyze biomarkers (0.002-100 mg/L). For adults, mortality, genotoxicity, and biomarkers were assessed in five different concentrations of VLX (1-100 mg/L). The median lethal concentration (LC50-168h) was 274.1 mg/L for embryos/larvae, and >100 mg/L for adults (LC50-96h). VLX decreased the heart rate frequency and caused premature hatching and lack of equilibrium in embryos/larvae exposed to different concentrations ranging from 100 to 562.5 mg/L. The activity of acetylcholinesterase (AChE) was inhibited in larvae exposed to 1, 25 and 100 mg/L. Glutathione-S-transferase (GST) activity was reduced in both larvae and adults after exposure to different concentrations, mainly at 25 mg/L. For both larvae and adults, lactate dehydrogenase (LDH) activity increased after 100 mg/L of VLX exposure. No DNA damage was observed in peripheral erythrocytes. Exposure to VLX may cause adverse effects on zebrafish in their early and adult life stages, interfering with embryo-larval development, and can induce physiological disturbances in adults.

CANCER RESEARCH COMMUNICATIONS 2023; 3:1013-1025. [PMID: 37377607 PMCID: PMC10259481 DOI: 10.1158/2767-9764.crc-23-0003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 01/02/2023] [Revised: 03/14/2023] [Accepted: 05/17/2023] [Indexed: 06/29/2023]
Abstract
Recent preclinical studies have linked antidepressants (AD) to their potential anticancer effects in multiple cancers, but the impact on lung cancer remains unclear. This meta-analysis examined the associations between ADs and lung cancer incidence and survival. The Web of Science, Medline, CINAHL, and PsycINFO databases were searched to identify eligible studies published by June 2022. We conducted a meta-analysis using a random-effects model to compare the pooled risk ratio (RR) and 95% confidence interval (CI) in those treated with or without ADs. Heterogeneity was examined using Cochran Q test and inconsistency I2 statistics. The methodologic quality of the selected studies was assessed using the Newcastle-Ottawa Scale for observational studies. Our analysis, including 11 publications involving 1,200,885 participants, showed that AD use increased lung cancer risk by 11% (RR = 1.11; 95% CI = 1.02-1.20; I2 = 65.03%; n = 6) but was not associated with overall survival (RR = 1.04; 95% CI = 0.75-1.45; I2 = 83.40%; n = 4). One study examined cancer-specific survival. Subgroup analysis showed that serotonin and norepinephrine reuptake inhibitors (SNRIs) were associated with an increased lung cancer risk by 38% (RR = 1.38; 95% CI = 1.07-1.78; n = 2). The quality of selected studies was good (n = 5) to fair (n = 6). Our data analysis suggests that SNRIs were associated with an elevated risk of lung cancer, raising concerns regarding the use of AD treatment in patients vulnerable to lung cancer. The effects of ADs-particularly SNRIs-and their interplay with cigarette use and lung cancer risk in vulnerable patients merits further study. Significance In this meta-analysis of 11 observational studies, we found evidence of a statistically significant association between the use of certain ADs and lung cancer risk. This effect merits further study, particularly as it relates to known environmental and behavioral drivers of lung cancer risk, such as air pollution and cigarette smoke.

Abstract
Paroxetine (PRX) is one of the most used antidepressants and an emerging contaminant with potential harmful effects to the environment and human health. The present study investigates in detail the toxic potential of PRX using a battery of bioassays on fresh- and marine species, marine bacteria, and human lymphocytes. All the tested organisms and human lymphocytes were exposed at concentrations ranging from μg L-1 to mg L-1. It was found that PRX can cause toxic effects to aquatic organisms at environmental relevant concentrations (μg L-1 level). A significant effect of PRX was observed in all tested algal species especially at the first 24 h. However, differences in responses and sensitivities among the tested algal species were observed. The most sensitive organism was found to be Dunaliella tertiolecta with IC50 = 0.092 mg L-1 (72 h). In the case of Aliivibrio fischeri, EC50 values were determined to be 16.65, 14.31 and 14.41 mg L-1 for 5, 15 and 30 min of exposure, respectively. PRX also induced cytotoxic and genotoxic effects in human lymphocytes. A dose-dependent increase in micronucleus frequencies was occurred at all tested concentrations with a statistically significant increase in micronucleus frequencies at the medium to high PRX tested concentrations. The findings of the present study expand the available toxicity profile of PRX on aquatic organisms and the knowledge about the potential risk of PRX to induce genotoxic effects in cultured human lymphocytes.

Abstract
The analysis of experimental data on the study of the genotoxic activity of psychotropic drugs published over the past 25 years has been carried out. It has been shown that the information describing the genotoxicity of psychotropic drugs is characterized by fragmentation, contradictions, and the conditions for their experimental production often do not meet modern requirements. Conclusions about the presence or absence of genotoxic properties can be made only for 9.6% 94 examined drugs. The need for a large-scale systematic reassessment of the genotoxicity of psychotropic drugs, especially drugs of the first generation, on the basis of modern methodology, including studies of mutagen-modifying activity, has been proven. The expediency of monitoring the genotoxic status of patients receiving psychotropic drugs is emphasized, which should contribute to an adequate assessment of the genotoxic risk of their use and objectification of approaches when choosing a drug for the safe therapy. The urgency of conducting research to determine the role of primary DNA damage in the pathogenesis of mental illnesses has been substantiated.

Abstract
We evaluated the duloxetine DNA damaging capacity utilizing the comet assay applied to mouse brain and liver cells, as well as its DNA, lipid, protein, and nitric oxide oxidative potential in the same cells. A kinetic time/dose strategy showed the effect of 2, 20, and 200 mg/kg of the drug administered intraperitoneally once in comparison with a control and a methyl methanesulfonate group. Each parameter was evaluated at 3, 9, 15, and 21 h postadministration in five mice per group, except for the DNA oxidation that was examined only at 9 h postadministration. Results showed a significant DNA damage mainly at 9 h postexposure in both organs. In the brain, with 20 and 200 mg/kg we found 50 and 80% increase over the control group (p ≤ 0.05), in the liver, the increase of 2, 20, and 200 mg/kg of duloxetine was 50, 80, and 135% in comparison with the control level (p ≤ 0.05). DNA, lipid, protein and nitric oxide oxidation increase was also observed in both organs. Our data established the DNA damaging capacity of duloxetine even with a dose from the therapeutic range (2 mg/kg), and suggest that this effect can be related with its oxidative potential.

Abstract
RATIONALE Depression is a major mental disorder affecting millions of people worldwide. Serotonin and norepinephrine reuptake inhibitors (SNRIs) are one of the antidepressant drugs prescribed for depression treatment. OBJECTIVE AND METHOD There are many contradiction studies about the adverse effect and genotoxicity of SNRIs. So here, based on the guidelines proposed at the PRISMA statement, we performed a quantitative systematic review by searching international electronic databases (PubMed, Scopus, Embase, and Web of Science) for published documents on SSNRIs and their genotoxicity effects. RESULTS The database searches retrieved 336 records, 18 of which met the inclusion criteria. Evaluation of the selected articles showed that a total of 9 articles were appropriate for final review. Most of these studies (78%) reported positive results for the genotoxicity of SNRIs CONCLUSION: Finally, we can conclude that these drugs have the potential to damage DNA.

Abstract
This study aimed to assess the prevalence of medical and nonmedical use of psychiatric medication among undergraduate students of health sciences from a public university in Brasil. Another objective was to determine the frequency of nuclear morphological abnormalities in the buccal mucosa of students using psychiatric drugs. A cross-sectional study based on a Web survey was carried out with 375 health sciences undergraduate students from schools of Pharmacy, Physical Education, Nutrition, and Medicine. Additionally, spontaneous genetic damages in exfoliated cells of the buccal mucosa of 41 individuals by counting micronucleus (MN) and binucleated (BN) cells frequencies were evaluated. The results showed 76 (20.3%) of students reported the use of psychotropic drugs after enrolling in university. The majority of these students were from Pharmacy and Medicine programs, females, aged between 18-25 years old, nonsmokers, alcohol addicts, and with a family history of mental illness. In addition, Medical students, individuals with high-income, who live alone and are in the last period of the program are more likely to use psychotropic drugs. Moreover, exposure to psychiatric medication was able to increase the number of binucleated cells. These results provide evidence that the use of psychoactive drugs is increased in the academic context and may be related to the failure of the cell cycle.

Abstract
The potential genotoxic effect of venlafaxine hydrochloride (venlafaxine), an antidepressant drug-active ingredient, was investigated by using in vitro chromosome aberrations (CAs) and cytokinesis-block micronucleus (CBMN) assays in human peripheral blood lymphocytes (PBLs). Mitotic index (MI) and cytokinesis-block proliferation index (CBPI) were also calculated to determine the cytotoxicity of this active drug. For this aim, the human PBLs were treated with 25, 50, and 100 µg/ml venlafaxine for 24 h and 48 h. The results of this study showed that venlafaxine significantly induced the formation of structural CA and MN for all concentrations (25, 50, and 100 µg/ml) and treatment periods (24 h and 48 h) when compared with the negative and the solvent control (except 25 µg/ml at 48 h for MN). In addition, the increases in the percentage of structural CA and MN were concentration-dependent for both treatment times. With regard to cell cycle kinetics, venlafaxine significantly decreased the MI at all concentrations, and also CBPI at the higher concentrations for both treatment times as compared to the control groups. The present results indicate for the first time that venlafaxine had significant clastogenic and cytotoxic effects at the tested concentrations (25, 50, and 100 µg/ml) in the human PBLs, in vitro; therefore, its excessive and careless use may pose a potential risk to human health.

Abstract
Objective: The existing evidence suggests an association between depression and memory impairment. The objective of present study was to assess the effect of low dose caffeine with duloxetine and bupropion on memory. Materials and Methods: Mice were divided randomly into seven groups. Intra-peritoneal treatment of normal saline (10 ml/kg), caffeine (10 mg/kg), duloxetine (10 mg/kg), bupropion alone (10 mg/kg), caffeine + duloxetine (5 mg/kg, each), caffeine + bupropion (5 mg/kg, each), and bupropion + duloxetine (5 mg/kg, each) were given to groups I-VII, respectively. Elevated plus maze was used to evaluate transfer latency (TL) and Morris water maze was used to estimate the time spent in target quadrant. Results: Caffeine with duloxetine treated group was better than other combination treated groups in terms of a significant decrease in TL and increase in the time spent in target quadrant recorded. Conclusion: Combining lower dose of caffeine with duloxetine may enhance cognitive benefits than respective monotherapies.

Abstract
Duloxetine is a widely used antidepressant worldwide. In the present report, we evaluated its capacity to induce micronucleated polychromatic erythrocytes (MNPEs) and micronucleated normochromatic erythrocytes (MNNEs) in mice. Two assays were performed, one with a single chemical administration and the other with daily chemical administration. In the first, we administered the antidepressant once to groups of 5 mice by the intragastric (i.g.) route (2, 20, and 200 mg/kg) and performed the analysis at 24, 48, and 72 h postadministration. A control group administered i.g. distilled water was included in the assay, as well as another treated with the micronuclei-inducing chemical daunorubicin (2.5 mg/kg, injected intraperitoneally (i.p.)). In this assay, we found significant damage induced by duloxetine starting from the first time evaluated, showing the highest MNPE increase at the end of the assay. We observed a saturation effect as well, suggested by a decreasing relative efficiency with respect to each tested dose. In a second assay, we administered the antidepressant i.g. every day for 5 weeks (2, 6, and 12 mg/kg), and micronuclei analysis was performed at the end of each week. In this study, we also found a significant increase in both MNPEs and MNNEs which was clear by the second week of administration. Our results suggest that short-term as well as cumulative damage is produced by duloxetine. Thus, confirmation of the observed genotoxic potential in other models seems advisable, as well as caution when prescribing this antidepressant.

Abstract
There is a strong association between depression and memory impairment. The present study aims to assess the nootropic activity of duloxetine and piracetam combination. Male Swiss Albino mice were divided randomly into 4 groups. Treatment of normal saline (10 ml/kg), duloxetine (10 mg/kg), piracetam (100 mg/kg), and duloxetine (5 mg/kg) plus piracetam (50 mg/kg) were given through intra-peritoneal route to group I-IV, respectively. Transfer latency in elevated plus maze (EPM) and time spent in target quadrant in Morris water maze (MWM) were recorded. Estimation of brain monoamines in hippocampus, cerebral cortex, and whole brain were done using HPLC with fluorescence detector. Piracetam treated group showed significant decrease in transfer latency in EPM and increase in time spent in target quadrant recorded in MWM. Combination treated group failed to produce statistically significant nootropic effect in both EPM and MWM. Combination treated group failed to increase brain monoamine levels when compared against duloxetine and piracetam treated groups, separately. But there was exception of significant increase in norepinephrine levels in hippocampi when compared against duloxetine treated group. Results indicate no cognitive benefits with piracetam plus duloxetine combination. These findings can be further probed with the aim of understanding the interaction between duloxetine and piracetam as a future endeavor.

Effects of acute and chronic administration of fenproporex on DNA damage parameters in young and adult rats. Mol Cell Biochem 2013; 380:171-6.

Abstract
Obesity is a chronic and multifactorial disease, whose prevalence is increasing in many countries. Pharmaceutical strategies for the treatment of obesity include drugs that regulate food intake, thermogenesis, fat absorption, and fat metabolism. Fenproporex is the second most commonly consumed amphetamine-based anorectic worldwide; this drug is rapidly converted in vivo into amphetamine, which is associated with neurotoxicity. In this context, the present study evaluated DNA damage parameters in the peripheral blood of young and adult rats submitted to an acute administration and chronic administration of fenproporex. In the acute administration, both young and adult rats received a single injection of fenproporex (6.25, 12.5 or 25 mg/kg i.p.) or vehicle. In the chronic administration, both young and adult rats received one daily injection of fenproporex (6.25, 12.5, or 25 mg/kg i.p.) or Tween for 14 days. 2 h after the last injection, the rats were killed by decapitation and their peripheral blood removed for evaluation of DNA damage parameters by alkaline comet assay. Our study showed that acute administration of fenproporex in young and adult rats presented higher levels of damage index and frequency in the DNA. However, chronic administration of fenproporex in young and adult rats did not alter the levels of DNA damage in both parameters of comet assay. The present findings showed that acute administration of fenproporex promoted damage in DNA, in both young and adult rats. Our results are consistent with other reports which showed that other amphetamine-derived drugs also caused DNA damage. We suggest that the activation of an efficient DNA repair mechanism may occur after chronic exposition to fenproporex. Our results are consistent with other reports that showed some amphetamine-derived drugs also caused DNA damage.

Abstract
AIM Aripiprazole is an antipsychotic agent to treat schizophrenia, which acts through dopamine D(2) partial agonism, serotonin 5-HT(1A) partial agonism and 5-HT(2A) antagonism. This study was designed to evaluate the neurobehavioral effects and genotoxic/mutagenic activities of the agent, as well as its effects on lipoperoxidation. METHODS Open field and inhibitory avoidance tasks were used. Thirty min before performing the behavioral tasks, adult male CF-1 mice were administered aripiprazole (1, 3 or 10 mg/kg, ip) once for the acute treatment, or the same doses for 5 d for the subchronic treatment. Genotoxic effects were assessed using comet assay in the blood and brain tissues. Mutagenic effects were evaluated using bone marrow micronucleus test. Lipoperoxidation was assessed with thiobarbituric acid reactive substances (TBARS). RESULTS Acute and subchronic treatments significantly decreased the number of crossing and rearing in the open field task. Acute treatment significantly increased the step-down latency for both the short- and long-term memory in the inhibitory avoidance task. Subchronic treatments with aripiprazole (3 and 10 mg/kg) caused significant DNA strain-break damage in peripheral blood but not in the brain. Mutagenic effect was not detected in the acute and subchronic treatments. Nor TBARS levels in the liver were affected. CONCLUSION Aripiprazole improved memory, but could impair motor activities in mice. The drug increased DNA damage in blood, but did not show mutagenic effects, suggesting that it might affect long-term genomic stability.

Abstract
Memantine is an aminoadamantane drug useful in neurodegenerative diseases, with beneficial effects on cognitive functions. Some studies have shown that memantine protects brain cells, thereby decreasing glutamate excitotoxicity. This study evaluated the genotoxic/antigenotoxic and mutagenic effects of memantine in CF-1 mice, following standardized protocols. Memantine was administered i.p. at 7.5, 15 or 30 mg/kg for three consecutive days. Blood and brain samples were collected to assess DNA damage using the alkaline comet assay. The mutagenic effect was assessed using the bone marrow micronucleus test. In addition, possible antioxidant effects were evaluated measuring the survival of Saccharomyces cerevisiae yeast strains [wild-type (WT) and isogenic mutants lacking superoxide dismutase] to cotreatment of memantine plus hydrogen peroxide. Memantine decreased DNA oxidative damage mainly in brain tissue. This antigenotoxic effect corroborated an increase observed in the survival of S. cerevisiae WT strain against hydrogen peroxide-induced damage. Furthermore, memantine did not increase the micronucleus frequency. The overall results indicate that memantine showed no mutagenic activity, did not cause DNA damage in the blood and brain tissues and showed antigenotoxic effects in brain tissue.

Abstract
Plants from the genus Piper are economically useful and some species have been indicated because of their medicinal properties in the central nervous system. However, few studies about toxicity and neurobehavioral effects have been conducted. In this study, two Piper species, P. amalago and P. mikanianum were investigated in rats to determine acute toxicity and to evaluate the ansiogenic/ansiolytic properties in the elevated plus-maze and the effects on locomotion and exploration in an open field. Additionally, genotoxic activities were evaluated, using the comet assay in several tissues and the micronucleus assay in bone marrow. The phytochemical analysis of both Piper species leaves suggests the presence of amide, essential oils, flavonoids and phenolic compounds. The LD(50) of P. amalago and P. mikanianum were estimated as 2,545 and 1,661 mg/kg, respectively. The behavioral and genotoxic parameters were determined after an intraperitoneal administration of P. amalago (250 or 420 mg/kg) or P. mikanianum (160 or 270 mg/kg). Both plants decreased the number of entries and time spent in the open arms in the plus-maze test, indicating an anxiogenic effect. Only P. mikanianum affected locomotion and exploration in the open field behavior test. No genotoxic or mutagenic effect was observed. Our results suggest that these Piper species act on the central nervous system, without induce genetic toxicity.
