Abstract
Cardiovascular diseases (CVD) are one of the main causes of mortality in the world. The development of these diseases has a specific factor-alteration in blood platelet activation. It has been shown that phenolic compounds have antiplatelet aggregation abilities and a positive impact in the management of CVD, exerting prominent antioxidant, anti-inflammatory, antitumor, cardioprotective, antihyperglycemic, and antimicrobial effects. Thus, this review is intended to address the antiplatelet activity of phenolic compounds with special emphasis in preventing CVD, along with the mechanisms of action through which they are able to prevent and treat CVD. In vitro and in vivo studies have shown beneficial effects of phenolic compound-rich plant extracts and isolated compounds against CVD, despite that the scientific literature available on the antiplatelet aggregation ability of phenolic compounds in vivo is scarce. Thus, despite the current advances, further studies are needed to confirm the cardioprotective potential of phenolic compounds towards their use alone or in combination with conventional drugs for effective therapeutic interventions.

Abstract
BACKGROUND Opioid analgesics are prescribed for the moderate to severe pain in the clinic. New analogs of µ-opioid receptors are introduced because they may have less adverse effects and better efficacy. However, these new analogs have to be screened for their receptor affinity before entering clinical trial phases. A common method to do such screening is using radioligand-binding-assay, which is a fast and precise screening technique if the assays are done at an optimum condition. One of the main challenges in this type of screening is to separate free/unbound radioligands from bound radioligands. In this study, we applied a centrifugation method instead of a filtration method to separate free radioligands from bound radioligands, and also optimized the conditions for radioligand receptor binding studies of µ-opioid receptors, saturation, and the competition. METHODS We used the midbrain and brainstem of naltrexone-treated rats as a source of µ-opioid receptors, and [3H]-DAMGO as the radioligand. Naloxone was also used to determine non-specific binding. A given amount of membrane protein was incubated with an increasing amount of radioligand at 37 °C to saturate the receptors at equilibrium and the amount of radioligand saturated in the receptors were used in competition studies. RESULTS 160 µg membrane protein saturated with 20 nM [3H]-DAMGO at 37 °C for 35 min with Kd (15.06 nM, 95% CI 8.117-22.00) and Bmax (0.4750 pmol/mg, 95% CI 0.3839-0.5660). CONCLUSION Applying the centrifugation method instead of the filtration to separate free from bound radioligand produced repeatable and reliable results. The optimum conditions for radioligand binding were used in competition studies which resulted in the expected outcomes.

Abstract
Acrolein is a clear, colorless liquid and a highly reactive α, β-unsaturated aldehyde. Acrolein, a byproduct and initiator of oxidative stress, has a major role in the pathogenesis of disorders including pulmonary, cardiovascular, atherosclerosis, and neurodegenerative diseases. Environmental or dietary exposure and endogenous production are common sources of acrolein. Widespread exposure to acrolein is a major risk for human health; therefore, we decided to investigate the neurological effects of acrolein. In this study, we used male Sprague-Dawley rats and exposed them orally to acrolein (0.5, 1, 3, and 5 mg/kg/day) for 90 days and investigated the neurobehavioral and electrophysiological disturbances. We also assessed the correlation between neurotoxicity and CSF concentration of acrolein in the rats. The results showed that chronic oral administration of acrolein at 5 mg/kg/day impaired learning and memory in the neurobehavioral tests. In addition, acrolein decreased the release of excitatory neurotransmitters such as glutamate in electrophysiological studies. Our data demonstrated that chronic oral exposure of acrolein at a dose of 5 mg/kg leads to a direct correlation between neurotoxicity and its CSF concentration. In conclusion, exposure to acrolein as a major pollutant in the environment may cause cognitive problems and may have serious neurocognitive effects on humans.

Abstract
Benzodiazepines (BZDs) have been widely used in neurological disorders such as insomnia, anxiety, and epilepsy. The use of classical BZDs, e.g., diazepam, has been limited due to adverse effects such as interaction with alcohol, ataxia, amnesia, psychological and physical dependence, and tolerance. In the quest for new benzodiazepine agonists with more selectivity and low adverse effects, novel derivatives of 4,6-diphenylpyrimidin-2-ol were designed, synthesized, and evaluated. In this series, compound 2, 4-(2-(benzyloxy)phenyl)-6-(4-fluorophenyl)pyrimidin-2-ol, was the most potent analogue in radioligand binding assay with an IC50 value of 19 nM compared to zolpidem (IC50 = 48 nM), a nonbenzodiazepine central BZD receptor (CBR) agonist. Some compounds with a variety of affinities in radioligand receptor binding assay were selected for in vivo evaluations. Compound 3 (IC50 = 25 nM), which possessed chlorine instead of fluorine in position 4 of the phenyl ring, exhibited an excellent ED50 value in most in vivo tests. Proper sedative-hypnotic effects, potent anticonvulsant activity, appropriate antianxiety effect, and no memory impairment probably served compound 3, a desirable candidate as a benzodiazepine agonist. The pharmacological effects of compound 3 were antagonized by flumazenil, a selective BZD receptor antagonist, confirming the BZD receptors' involvement in the biological effects of the novel ligand.

Abstract
Prosopis farcta (Banks & Sol.) J.F.Macbr. is an emerging medicinal plant containing a diverse array of phytochemicals, including protein, fat, carbohydrate, fibre, alkaloids, fatty acids, glycosides, and polyphenols, with strong antioxidant potential. However, the screening and characterization of phenolic compounds in P. farcta is limited. This study is conducted to determine the polyphenol contents and their antioxidant activity in P. farcta leaves samples via liquid chromatography-electrospray ionization quadrupole time-of-flight mass spectrometry (LC-ESI-QTOF-MS/MS) and high-performance liquid chromatography-photodiode array (HPLC-PDA). Total phenolic content (TPC), total flavonoid content (TFC), and total tannins content (TTC) were determined for polyphenol estimation. The antioxidant properties were measured by total antioxidant capacity (TAC), 2,2'-Diphenyl-2-picrylhydrazyl (DPPH), Ferric Reducing Antioxidant Power (FRAP), and 2,2"²-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS). LC-ESI-QTOF-MS/MS was used to identify and characterize 47 phenolic compounds, which mainly included phenolic acids (13), flavonoids (28), other polyphenols (4), lignans (1), and stilbenes (1). According to HPLC-PDA quantification, chlorogenic acid (9.78 ± 2.15 mg/g dw) was the most abundant phenolic acid, while the main flavonoids included catechin (12.73 ± 1.29 mg/g dw) and kaempferol (7.93 ± 1.47 mg/g dw). The study demonstrated the significance of P. farcta as a rich source of phenolic compounds with antioxidant capacity that can be widely used in food, beverage, feed, and pharmaceutical applications.

Abstract
Benzodiazepines (BZD) are among the main classes of tranquilizing drugs, bearing much less toxicity compared to other drugs acting on the CNS. Considering the pharmacophore model of BZD binding to GABA-A receptor, novel diphenyl 1,3,4-oxadiazole compounds as BZD ligands were designed. The compounds were synthesized and structurally confirmed using LCMS, IR and NMR techniques. We investigated the affinity of the compounds to BZD receptors using radioligand [3H]-flumazenil by in-vitro studies. In addition, sedative-hypnotic, anxiety, anticonvulsant, muscle relaxant, memory impairment, and motor coordination activities of the synthesized compounds were evaluated using in-vivo studies. Based on in-vitro studies, compounds 7i and 7j were the most potent with IC50 values of 1.54 and 1.66 nM respectively. In-vivo studies showed that compound 7i has the highest impact on increased sedation, muscle relaxation, and decreased anxiety and these observations were antagonized by flumazenil. Compounds 7e and 7i were the most potent anticonvulsant agents among synthesized compounds in both MES and PTZ induced seizure tests. All synthesized compounds significantly decreased latency to fall in the Rotarod test but none of them had a significant impact on the memory impairment test.

Abstract
Antidepressant-like activity of T. kotschyanus has been recently reported by scientists but insufficient attention has been so far devoted to T. kotschyanus, and there is a lack of information on the other neurobehavioral effects and side effects of this species. In the current study, the anticonvulsant, anxiolytic, and sedative-hypnotic, effects of Thymus kotschyanus extract on male NMRI mice were evaluated using pentylenetetrazole, maximal electroshock, elevated plus maze, and pentobarbital-induced sleeping tests. Since phenolic compounds and flavonoids have main roles in pharmacological effects of most plant extracts, the phenolic and flavonoid contents of the extract were measured with Folin-Ciocalteu and AlCl3 reagents. Acute toxicity, passive avoidance, and open field tests were carried out to assess the toxicity of the extract. To find out the possible mechanism of action, flumazenil as the specific GABAA receptor antagonist was used. Anticonvulsant and hypnotic effects of the extract were observed at 400 and 600 mg/kg. The extract at the dose of 200 mg/kg revealed significant anxiolytic effects, but it did not show any adverse effects on learning and memory at all the tested doses. Results of this study indicate that Thymus kotschyanus extract has anticonvulsant, anxiolytic, and hypnotic effects, which are likely related to the ability of some phenolic compounds to activate α1-containing GABAA receptors but more experiments still need to be carried out in order to find the exact mechanism, active component, and the toxicity of the Thymus kotschyanus extract.

Abstract
Cardiovascular diseases are a leading cause of worldwide death and excessive platelet is closely related with their pathogenesis. Different plants and natural compounds have demonstrated anti-platelet effects. The aim of this study was to report the high-performance thin-layer chromatography (HPTLC) fingerprinting and anti-platelet-aggregation activities of different leaf extracts (n-hexane, chloroform, ethyl acetate, methanol and aqueous) of Prosopis farcta (Syrian mesquite) plant. The results showed a 100% inhibition of aggregation activity after plasmatic adenosine diphosphate (ADP) aggregation activation of ethyl acetate, ethanolic, methanolic and aqueous extracts, at 60 mg/mL concentration. The IC50 ADP value of these extracts ranged between 4.07 and 11.39 mg/mL. Moreover, these extracts reported the highest amounts of phenolic and flavonoid contents. In conclusion, phytochemicals present in P. farcta leaves have anti-platelet-aggregation activities. Future studies are needed to identify the compounds with anti-platelet potential present in P. farcta.

Abstract
The aim of this study is to investigate the novel application of a handheld near infra-red spectrophotometer coupled with classification methodologies as a screening approach in detection of adulterated lime juices. For this purpose, a miniaturized near infra-red spectrophotometer (Tellspec®) in the spectral range of 900-1700 nm was used. Three diffuse reflectance spectra of 31 pure lime juices were collected from Jahrom, Iran and 25 adulterated juices were acquired. Principal component analysis was almost able to generate two clusters. Partial least square discriminant analysis and k-nearest neighbors algorithms with different spectral preprocessing techniques were applied as predictive models. In the partial least squares discriminant analysis, the most accurate prediction was obtained with SNV transforming. The generated model was able to classify juices with an accuracy of 88% and the Matthew's correlation coefficient value of 0.75 in the external validation set. In the k-NN model, the highest accuracy and Matthew's correlation coefficient in the test set (88% and 0.76, respectively) was obtained with multiplicative signal correction followed by 2nd-order derivative and 5th nearest neighbor. The results of this preliminary study provided promising evidence of the potential of the handheld near infra-red spectrometer and machine learning methods for rapid detection of lime juice adulteration. Since a limited number of the samples were used in the current study, more lime juice samples from a wider range of variability need to be analyzed in order to increase the robustness of the generated models and to confirm the promising results achieved in this study.

Abstract
In this study, we focused on the neuro-behavioral profile, toxicity, and possible mechanisms of action of Dorema ammoniacum gum essential oil (DAG-EO). For this purpose, passive avoidance and Y-maze tests were performed to evaluate the potential effect of DAG-EO in the attenuation of memory impairment induced by 49 days administration of D-galactose and acute injection of scopolamine. Anticonvulsant and anti-nociceptive activities of DAG-EO were evaluated in the pentylenetetrazole and maximal electroshock-induced models of seizure and acetic acid-induced writhing tests, respectively. To find the possible mechanism of action, flumazenil and naloxone were used. Furthermore, the possible side effects were determined in the open field, grip strength, and rotarod tests. Our findings supported that 7-day administration of DAG-EO (50 and 100 mg/kg) improves memory impairment induced following administration of D-galactose and scopolamine. It was also revealed that DAG-EO possesses a dose-dependent sedative-hypnotic (100 mg/kg), anticonvulsant (ED50 ≈ 170 mg/kg), and anti-nociceptive (ED50 ≈ 175 mg/kg) activities possibly mediated via directly and/or indirectly modulation of GABAA and opioid receptors. No side effect was observed except muscle relaxation which was less than that of diazepam. The output of this study confirms anti-seizure, anti-nociceptive, sedative-hypnotic, and memory-enhancing properties of DAG-EO by modulation of GABAA receptors.

Abstract
Several studies have supported the preventive and therapeutic values of phenolic compounds including chlorogenic acid, syringic acid, vanillic acid, ferulic acid, caffeic acid, luteolin, rutin, catechin, kaempferol, and quercetin in mental disorders. Since these secondary metabolites are reported as the phenolic compounds of Artemisia dracunculus (A. dracunculus) and Stachys lavandulifolia (S. lavandulifolia), the main aim of this study was the evaluation and comparison of the phenolic contents, flavonoids, and antidepressant-like activity of Artemisia dracunculus with Stachys lavandulifolia. Antidepressant-like activity of the extracts was evaluated in the forced swimming test (FST) and the tail suspension test (TST). Moreover, the open field test was conducted to evaluate the general locomotor activity of mice following treatment with the extracts. Since phenolic compounds and flavonoids play main roles in pharmacological effects, the phenolic and flavonoid contents of the extracts were measured. Though significant difference between the phenolic contents of the extracts was not observed, but S. lavandulifolia exhibited higher flavonoid contents. Animal treatment with extracts decreased the immobility times in both FST and TST compared to the vehicle group without any significant effect on the locomotor activity of animals. Also, S. lavandulifolia at 400 mg/kg showed higher potency in both tests compared to A. dracunculus. Our results provided promising evidence on the antidepressant-like activity of both extracts which could be related to flavonoids as the main components of the extracts, but more studies need to be conducted to specify the main compounds and the mechanisms involved in the observed effects.

Abstract
In Iranian traditional medicine, Inula species have been used for the treatment of seizure. In this study we decided to investigate the anticonvulsant activity of seven species from this genus to find an effective remedy for seizure with less adverse effects compared to the available medicines. Aqueous and methanolic extracts of Inula britannica, Inula helenium, Inula viscidula, Inula oculus-christi, Inula aucheriana, Inula thapsoides, and Inula salicina were prepared and their antiepileptic activity was investigated by maximal electroshock (MES) and pentylentetrazole (PTZ) tests on Male NMRI Albino mice. Diazepam was used as positive control in both tests. In addition, two extracts with the best anticonvulsant activities were selected and their sedative and hypnotic effects were evaluated using open field and righting reflex tests, respectively. The effects of the both extracts on memory and motor coordination were also assessed by step-through passive avoidance and rotarod tests, respectively. Aqueous extract of Inula britannica and Inula viscidula showed the best activity in MES model and their ED50 (with 95% confidence interval) was 19.5 (7.9~48.5) mg/kg and 12.7(10.0~16.3) mg/kg, respectively. None of the extracts showed noticeable anticonvulsant effects in the PTZ model. The active extracts also showed sedative-hypnotic effects in righting reflex and open field tests. Furthermore, both extracts did not affect the memory and motor coordination in the experimental models. The anticonvulsant and sedative activities of the extracts were antagonized by flumazenil, indicating that benzodiazepine receptors are probably involved in the effects. This study indicates that Inula britannica and Inula viscidula are good candidates for further phytochemical and mechanistic studies in order to find anticonvulsant and sedative-hypnotic compounds with less adverse effect on memory and motor coordination.

Abstract
Objective: A variety of approaches such as surgery, chemotherapy, radiotherapy, hormonal therapy and
immunotherapy are used to treat melanomas, but unfortunately in most case, the response is very weak and often side
effects are serious. This study concerns selective toxicity of an extract of Turbo coronatus on cells and mitochondria from
a syngeneic mouse model of melanoma. Methods: Cells and mitochondria isolated from extra tumoral and melanoma
tissues were exposed toa T. coronatus crude extract and fractions obtained by gel-filtration chromatography and assayed
for mitochondrial and cellular parameters. Result: Crude extract (375, 750 and 1,500 μg/ml) and fraction 1; F1; (275,
550 and 1100 μg/ml) of T. coronatus extract induced a significant (p<0.05) increase of the reactive oxygen species
(ROS) level, swelling of mitochondria, collapse of mitochondrial membrane potential (MMP), release of cytochrome
c and caspase-3 activation only in the mitochondria and cells obtained from melanoma but not extra tumoral tissues. In
addition, the F1 fraction decreased the percentage of viable cells and induced apoptosis in melanoma cells. Conclusion:
For the first time we could demonstrate that the F1 fraction of a T. coronatus extract, selectively induces ROS mediated
cytotoxicity by directly targeting mitochondria in melanoma tissues and it may be a suitable candidate for novel drug
treatment of malignant melanomas.

Abstract
Novel substituted amino acid tethered norsufentanil derivatives were synthesized by the four-component Ugi reaction. Norsufentanil was reacted with succinic anhydride to produce the corresponding carboxylic acid. The resulting carboxylic acid has undergone a multicomponent reaction with different aldehydes, amines, and isocyanides to produce a library of the desired compounds. In all cases, amide bond rotation was observed in the NMR spectra. In vivo analgesic activity of the synthesized compounds was evaluated by a tail flick test. Very encouraging results were obtained for a number of the synthesized products. Some of the synthesized compounds such as 5a, 5b, 5h, 5j, and 5r were found to be more potent than sufentanil, sufentanil citrate, and norsufentanil. Binding modes between the compounds and mu and delta-opioid receptors were studied by molecular docking method. The relationship between the molecular structural features and the analgesic activity was investigated by a quantitative structure-activity relationship model. The results of the molecular modeling studies and the in vivo analgesic activity suggested that the majority of the synthesized compounds were more potent than sufentanil and norsufentanil.

Abstract
Human papillomavirus (HPV) cause common warts, laryngeal papilloma, and genital condylomata and might lead to development of cervical cancer. Lactoferrin (LF) is a member of the transferrin family, which has antiviral activity against HPV-16. LF is an important player in the defense against pathogenic microorganisms and has also been shown to have activity against several viruses including herpesvirus, adenovirus, rotavirus, and poliovirus. Bovine LF (BLF) has been reported to be a more potent inhibitor of HPV entry in comparison to human LF. The goal of the present study is to formulate, evaluate and optimize transfersomal vesicles as a non-invasive transdermal delivery system which assumed to be a suitable for treatment of genital warts. Transfersomes have been prepared by two methods including reverse phase evaporation and thin film hydration with different ratios of cholesterol: lecithin: DOTAP in the presence of SDS or Tween 80. The transferosomes were then evaluated regarding size, polydispersity, and LF loading. In-vitro release studies in pH 5.3 and 7.4, stability evaluation in 4 °C and 25 °C, and TEM imaging hve been performed on optimized transferosomal lactoferrin. The optimized transferosomes were found to have 100 nm sizes with good polydispersity index and encapsulation efficiency of 91% for lactoferrin as well as sustained release of lactoferrin during 24 h. Transferosomal lactoferrin efficacy was evaluated by MTT assay. It was seen that the viral inhibitory concentration (IC50) of transfersomal lactoferrin has been significantly improved to nearly one tenth in comparison to free lactoferrin.

Abstract
Perfluorooctanesulfonate (PFOS), an anthropogenic fluorosurfactant, is one of the most common global pollutants. PFOS is used in various consumer products to provide soil, oil, and water resistance to materials used in clothing, upholstery, and food packaging. PFOS is persistent, bioaccumulative, and toxic to mammalian species. In this study, the cellular mechanisms involved in PFOS hepatotoxicity were evaluated. For this purpose, we determined oxidative stress markers including cell lysis, ROS generation, lipid peroxidation, glutathione depletion, mitochondrial membrane potential decrease, lysosomal membrane leakiness, and cellular proteolysis. Our results demonstrated that PFOS liver cytotoxicity was associated with reactive oxygen species (ROS) formation and lipid peroxidation in isolated rat hepatocytes. Incubation of hepatocytes with PFOS caused rapid depletion of hepatocyte glutathione (GSH), an important marker of cellular oxidative stress. Most of the PFOS-induced GSH depletion could be attributed to the expulsion of glutathione disulfide (GSSG). PFOS hepatotoxicity was inhibited by antioxidants and ROS scavengers, mitochondrial permeability transition (MPT) pore sealing agents, and endocytosis inhibitors. Our results suggest that PFOS hepatotoxicity might be the result of oxidative stress-induced lysosomal membrane leakiness and cellular proteolysis in rat hepatocytes.

Abstract
OBJECTIVES Coenzyme Q10 (CoQ10, ubiquinone) stands among the safest supplements in the elderly to protect against cardiovascular disorders. Noteworthy, CoQ10 deficiency is common in many surviving stroke patients as they are mostly prescribed statins for the secondary prevention of stroke incidence lifelong. Accordingly, the current study aims to experimentally examine whether CoQ10 supplementation in animals receiving atorvastatin may affect acute stroke-induced injury. METHODS Adult rats underwent transient middle cerebral artery occlusion after atorvastatin pretreatment (5 or 10 mg/ kg/day; po; 30 days) with or without CoQ10 (200 mg/kg/day). After 24 hours ischemic/reperfusion injury, animals were subjected to functional assessments followed by cerebral molecular and histological to detect inflammation, apoptosis and oxidative stress. RESULTS Animals dosed with 10 mg/kg presented the worst neurological function and brain damage in the acute phase of stroke injury. CoQ10 supplementation efficiently improved functional deficit and cerebral infarction in all stroke animals, particularly those exhibiting statin toxicity. Such benefits were associated with remarkable anti-inflammatory and anti-apoptotic effects, based on the analyzed tumor necrosis factor-α, interleukin-6, Bax/Bcl2 and cleaved caspase 3/9 immunoblots. Importantly, our fluoro-jade staining data indicated CoQ10 may revert the stroke-induced neurodegeneration. No parallel alteration was detected in stroke-induced oxidative stress as determined by malondialdehyde and 8-oxo-2'-deoxyguanosine levels. DISCUSSION These data suggest that all stroke animals may benefit from CoQ10 administration through modulating inflammatory and degenerative pathways. This study provides empirical evidence for potential advantages of CoQ10 supplementation in atorvastatin-receiving patients which may not shadow its antioxidant properties.

Abstract
A new series of 4-chloro-N-(2-(substitutedphenyl)-4-oxothiazolidin-3-yl)-2-phenoxybenzamide derivatives were designed, synthesized and biologically evaluated as anticonvulsant agents. The designed compounds have the main essential functional groups for binding to the benzodiazepine receptors and 4-thiazolidinone ring as an anticonvulsant pharmacophore. Some of the new synthesized compounds showed considerable anticonvulsant activity in electroshock and pentylenetetrazole-induced lethal convulsion tests. Compound 5i, 4-chloro-N-(2-(4-methoxyphenyl)-4-oxothiazolidin-3-yl)-2-phenoxybenzamide, with the best activity was selected for evaluation of other benzodiazepine pharmacological effects. This compound induced significant sedative-hypnotic activity. However, it does not impair the learning and memory in the experimental condition. Flumazenil was able to antagonize the sedative-hypnotic and anticonvulsant effects of compound 5i indicating that benzodiazepine receptors are highly involved in the pharmacological properties of the novel compounds.

Abstract
A rapid, simple and reproducible HPLC method was developed and validated for the analysis of nimodipine (NM) and/or its metabolite, oxidized nimodipine (OX-NM) in rat cerebrospinal fluid (CSF) and artificial CSF. The NM and OX-NM were eluted in less than 10 min with no interferences from the endogenous CSF peaks. Analysis was carried out on a Eurospher Performance (RP-C18, 250 × 4.6 mm) column and UV detection at 236 nm. The mobile phase consisted of acetonitrile and water (70:30 v/v, respectively) with a flow rate of 1 mL/min. Limit of detection was 0.1 μg/mL for OX-NM. The calibration curve was linear over the concentration range of 0.5-10 µg/mL and analytical recovery was more than 95%. The coefficients of variation for intra-day and inter-day assays were less than 5%.
