Currently, effective treatment options for PE are limited. This study aimed to evaluate the therapeutic potential of olive leaf extract (OLE) and nifedipine, alone and in combination, in improving pregnancy outcomes in rats induced with Nω-nitro-L-arginine methyl ester hydrochloride (L-NAME). Rats were treated with single and combination treatments of nifedipine and OLE for four weeks, after being induced with L-NAME for six weeks. Following gestational day assessment and systolic blood pressure testing, the rats were sacrificed, and blood samples were collected for Neutrophil Gelatinase-Associated Lipocalin (NGAL), Malondialdehyde (MDA), proteinuria and Creatinine (SCr) Levels examinations. The results revealed the combination of nifedipine and OLE significantly improved the results of several biomarker analyses associated with PE, including increased NGAL levels, a significant decrease in MDA levels, decrease in proteinuria and elevated creatinine levels. The combination nifedipine and OLE treatment also exhibited a significant antihypertensive effect compared to either nifedipine or OLE monotherapy, as evidenced by the reduction in systolic and diastolic blood pressure levels. This study provides novel evidence for the potential of olive leaf extract as a nutraceutical adjunct for the prevention and treatment of PE. The significant improvements observed in several pathological features associated with PE, including antihypertensive effects, warrant further investigation. Future research should focus on elucidating the underlying mechanisms of action and exploring the clinical applicability of olive leaf extract in human populations with PE.","PeriodicalId":508564,"journal":{"name":"Pharmacia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141004805","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 current study investigates Equisetum ramosissimum on levels of leptin, ghrelin, and their ratio in association with body weight changes in animals receiving standard and high-fat diet. Ethanolic extract was prepared by maceration and total phenols and flavonoids contents were determined using Folin-cicalto and AlCl3 methods. Study animals were fed with either standard or high-fat diets prior treatment with E. ramosissimum extract (500mg/kg). Body weights were monitored and serum concentrations of leptin, ghrelin and their ratios were determined. The plant extract comprised total phenols and flavonoids of 0.03 ± 0.01 mg/mg as Gallic acid, and 0.04 ± 0.03 mg/mg as quercetin, respectively. Findings revealed significant decrease in body weights of standard-diet animals and restoration of weight to normal after treatment with extract along with significant increase in serum ghrelin concentrations with strong correlation R and R2 values in respect to body weight. As well, significant reduction in serum leptin/ghrelin ratio was positively correlated with body weight and serum leptin levels. E. ramosissimum extract possessed promising characteristics on being introduced in dietary supplements and weight control regimens. The current study presented the influence of extract in decreasing body weight in animals fed with standard diet. Moreover, it restored the weights of obese animals which received the extract after gaining weight and being on high-fat diet. Further preclinical studies are warranted to reveal the translational potentials of E. ramosissimum extract and its vital effect on adipokines.","PeriodicalId":508564,"journal":{"name":"Pharmacia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140380219","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}

A significant advance has been made since the MW activation was introduced in the organic synthesis which can be confirmed with the rapid growth of the published papers on that topic. Microwave irradiation is gaining popularity since faster reaction time, higher yields, easier work-up and reduced energy input can be achieved. Furthermore, it appears in numerous green chemistry protocols. The aim of the current article was to provide insights into the microwave syntheses of pyrrole derivatives, focusing on the most used synthetic approaches - Paal-Knorr, Clauson-Kaas, Barton-Zard, Hantzsch and others. The article was divided into several sections starting with the principles of the microwave organic synthesis. Thereafter the structure and the main pharmacological effects of the pyrrole derivatives were examined. Subsequently, articles describing the synthesis of pyrroles via Paal-Knorr, Hantzsch, Clauson-Kaas and Barton– Zard were discussed.
