The objective of this study was to determine the phytochemical of cinnamon essential oil (EO) and to evaluate its antibacterial activity alone and in combination with some main components of EOs such as thymol, carvacrol, eugenol, or geraniol against three bacterial strains (Escherichia coli, Staphylococcus aureus, and Pseudomonas aeruginosa). The phytochemical analysis of cinnamon EO was evaluated using gas chromatography-flame ionization detector and gas chromatography-mass spectrometer analysis. The antibacterial activity of tested compounds was determined by agar disk diffusion and minimum inhibitory concentration (MIC) assays. The checkerboard method was used to quantify the efficacy of cinnamon EO in combination with those compounds. The results showed that the major compound in the cinnamon EO was trans-cinnamaldehyde (91.01%). Cinnamon oil was the highest antibacterial activity with MIC of 0.005, 0.005, and 0.02 mg/mL against E. coli, S. aureus, and P. aeruginosa, respectively. Synergistic activity was shown only against S. aureus by the combination of cinnamon EO and thymol. The additive effect was found against E. coli when cinnamon EO was combined with thymol or carvacrol, and against S. aureus when cinnamon EO was combined with carvacrol. However, the combination of EO and thymol or carvacrol showed an indifference action against P. aeruginosa. The combination of cinnamon EO with thymol or carvacrol can be used as an alternative therapeutic agent for medical application and as a natural preservative.","PeriodicalId":16966,"journal":{"name":"Journal of Reports in Pharmaceutical Sciences","volume":"9 1","pages":"104 - 109"},"PeriodicalIF":0.6,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43280821","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The product quality may differ depending on the type of material used and the distillation process. However, despite the many investigations on the chemical composition of different mint essential oils, the co-produced hydrosols have rarely been evaluated. Objectives: This study evaluated and compared the chemical composition of 10 mint hydrosol samples purchased from local markets of Fars province, Iran, to Mentha piperita and Mentha spicata authentic hydrosols. Materials and Methods: Essential oils of the samples were extracted via liquid–liquid extraction by petroleum ether and analyzed using gas chromatography–flame ionisation detector (GC-FID) and gas chromatography–mass spectrometry (GC-MS). Hydrosols were then clustered based on their components. Results and Conclusion: Approximately 91.3%–100% of the components and overall 31 constituents were identified with the majority of oxygenated monoterpenes. Menthol, (R)-(−)-carvone, and piperitenone were the three different major compounds in the market samples. High percentages of menthol and carvone in many samples suggest that each product could be biologically active, and moreover, could be a valuable water-soluble source of their constituents. However, lack of chemical evaluation and standardization in this industry leads to inconsistency in quality and undermines the credibility of the industry.","PeriodicalId":16966,"journal":{"name":"Journal of Reports in Pharmaceutical Sciences","volume":"9 1","pages":"52 - 58"},"PeriodicalIF":0.6,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48485393","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the low bioavailability and limited brain exposure of orally administered drugs pose a huge challenge to treat neurodegenerative and psychiatric disorders. So, the situation demands for targeting the drug to brain. For brain targeting, a number of factors are considered viz. molecular weight, route of administration, lipophilic character of drug and blood brain barrier (BBB). These factors limit the movement of drug into brain tissue through BBB. To overcome these problems, intranasal drug administration is one of the promising routes that bypasses BBB and cuts down the dose to be administered with better brain exposure to drug. Nasal route has been used for the administration of antihistamines, local analgesics and corticosteroids intended for local drug delivery in nasal allergy, nasal congestion and nasal infection. However, systemic drug delivery through this route has also been explored in recent times. For nose to brain drug delivery, olfactory and respiratory region are utilized which also enable delivery of larger molecules to reach brain tissues. Such delivery systems are generally pH or temperature dependent. Certain diseases of nervous system like migraine, dementia, parkinsonism, epilepsy and Alzheimer’s disease can be successfully treated through this route. This review attempts to highlight the anatomy of nose, mechanisms of drug delivery from nose to brain, critical factors in the formulation of delivery systems, nasal formulations and applications of nasal route for delivery of various drugs.","PeriodicalId":16966,"journal":{"name":"Journal of Reports in Pharmaceutical Sciences","volume":"9 1","pages":"168 - 175"},"PeriodicalIF":0.6,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43845768","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ipomoea aquatica is traditionally used for the treatment of some diseases. This study examined the protective effect of the ethanolic leaf extract of Ipomoea aquatica (EEIA) against CPT-induced hepatotoxicity in albino rats. Materials and Methods: Fifty-four adult male albino rats randomized into nine groups (six rats in each group) were treated orally with EEIA (100, 200, and 400 mg/kg) daily for 7 days and CPT (6 mg/kg) intraperitoneally on day 5 and 7, respectively. On day 8, the rats were anesthetized; blood samples were collected and evaluated for plasma liver function markers. Liver samples were harvested and evaluated for biochemical parameters and histology. Statistical Analysis: Data are presented as mean ± standard error of the mean (SEM). Statistical analysis was performed using one-way analysis of variance (ANOVA) and Tukey’s test. Results: CPT-induced hepatotoxicity was characterized by significant (P < 0.001) elevations in liver and plasma levels of aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, lactate dehydrogenase, gamma-glutamyl transferase, total bilirubin, and conjugated bilirubin when compared to control. The alterations in liver redox status of CPT-treated rats were marked by significant (P < 0.001) decreases in superoxide dismutase, catalase, glutathione, and glutathione peroxidase levels with significant (P < 0.001) increases in malondialdehyde levels when compared to control. The liver of CPT-treated rat was characterized by hepatocyte necrosis. The hepatotoxic effect of CPT was significantly abrogated in a dose-dependent fashion in rats pretreated with EEIA 100 mg/kg (P < 0.05), 200 mg/kg (P < 0.01), and 400 mg/kg (P < 0.001) when compared to CPT-treated rats. Conclusion: EEIA has potential as treatment for CPT-induced hepatotoxicity.","PeriodicalId":16966,"journal":{"name":"Journal of Reports in Pharmaceutical Sciences","volume":"9 1","pages":"25 - 30"},"PeriodicalIF":0.6,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45308220","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objectives: The aim of this work was to evaluate cytotoxicity of different fractions of Verbascum alceoides, which belongs to this genus. Materials and Methods: Aerial parts of this plant were collected from Doveiseh area in Kordestan province. The plant was extracted using a four-step extraction method with increasing solvent polarity (i.e., hexane, dichloromethane, chloroform-methanol [9:1], and methanol). The methanol extract was finally separated between water and butanol. Hexane, dichloromethane, chloroform-methanol, butanol, and aqueous partitions were then subjected to cytotoxicity evaluation. Showing the most potent cytotoxic effects, the butanolic partition was further fractionated by medium-performance liquid chromatography and similar eluates were pooled to prepare five final butanolic fractions, named A–E. Results: In vitro cytotoxicity of these fractions against human cervical epithelioid carcinoma (HeLa) and human umbilical vein endothelial cell (HUVEC) was evaluated using 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide assay. Fractions D, E, and A showed a significant and dose-dependent inhibition of cell proliferation (half maximal inhibitory concentration [IC50] of 30, 39.8, and 188.6 µg/mL, respectively). According to the preliminary thin-layer chromatography analysis, these cytotoxic effects may be mainly due to presence of saponin and flavonoid compounds. Conclusion: Future studies will be aimed to isolate and purify active constituents and investigate the effect of them on more different kinds of cancer cells.","PeriodicalId":16966,"journal":{"name":"Journal of Reports in Pharmaceutical Sciences","volume":"9 1","pages":"19 - 24"},"PeriodicalIF":0.6,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49378181","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although various dosing regimens of vitamin D have been used for the treatment of vitamin D deficiency, it is still unclear as to which dosing regimen can efficiently increase the serum level of vitamin D in different patient population. Aim: This study was designed to compare the efficacy of weekly and daily regimens of vitamin D3 in patients with vitamin D deficiency. Settings and Design: A randomized clinical trial was conducted in the autumn and winter of 2016 and 2017, Hamadan, Iran. Materials and Methods: A total of 130 patients with moderate to severe hypovitaminosis D were allocated into two groups: weekly 50,000 IU (routine recommended dose for vitamin deficiency treatment) or daily 4,000 IU (safe upper limit dose of vitamin D per day) of oral vitamin D3 for 8 and 14 weeks, respectively. The serum levels of 25-OH-vitamin D were measured in all patients at baseline and at the end of the treatment period. Results: Results of this study showed that though both dosing regimens can be effective in increasing the serum level of 25-OH-vitamin D, higher percentage of the subjects in the daily regimen group achieved the sufficient serum level of 25-OH-vitamin D when compared to the weekly regimen group. Conclusion: Accordingly, probably owing to better bioavailability of daily regimen of vitamin D3 and establishment of a more steady serum concentration compared with weekly regimen, it can be recommended as the preferred dosing regimen for effective treatment of vitamin D deficiency.","PeriodicalId":16966,"journal":{"name":"Journal of Reports in Pharmaceutical Sciences","volume":"9 1","pages":"110 - 117"},"PeriodicalIF":0.6,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46509126","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the recent past, Tagetes patula essential oils (EOs) and their phytochemistry and bioactivities have received great attention in research. Purpose and Methods: In this study, the component, antimicrobial activity, and antioxidant capacity (ferric-reducing antioxidant power assay) of EOs from five plant parts (shoot at vegetative growth stage [TPSV], shoot at flowering growth stage [TPSF], flower [TPF], fruit [TPS], and root [TPR]) of T. patula were investigated. The antibacterial activity against five gram-negative bacterial isolates (including Serratia fonticola, Klebsiella pneumoniae, Acinetobacter baumannii, Proteus mirabilis, and Escherichia coli) and five gram-positive bacterial isolates (including Staphylococcus aureus, S. epidermidis, S. saprophyticus, Streptococcus agalactiae, and Streptococcus oralis) was studied using broth microdilution method. FRAP assay was also used to evaluate their antioxidant activity. Results: One hundred and twenty-five compounds of the total EOs were identified, constituting a mixture of oxygenated monoterpenes (33%), monoterpene hydrocarbons (25%), oxygenated sesquiterpenes (19%), sesquiterpene hydrocarbons (12%), and furanocoumarins (8%). In this paper, for the first time, more than 60 new compounds were isolated from T. patula such as bergapten, sylvestrene, (E)-β-farnesene, (E)-epoxy-ocimene, (Z)-jasmone, γ-gurjunene, and γ-himachalene. The EOs of T. patula showed potent antibacterial activity against the studied bacteria with the highest growth inhibition observed in E. coli after 24 h of incubation (MIC value 0.08 and MBC value 0.32 µL/mL). The TPS-EO had the highest mean value for ferric-reducing ability at the three test times, whereas TPR-EO had no activity. Conclusion: It was concluded that the potential biocidal activity of T. patula EOs could be substantially associated with their oxygenated constituents or the synergistic activity of their major and minor chemical components.","PeriodicalId":16966,"journal":{"name":"Journal of Reports in Pharmaceutical Sciences","volume":"9 1","pages":"59 - 67"},"PeriodicalIF":0.6,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41369965","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
