Its mechanism of action includes enhancing GABAergic transmission, blocking voltage-gated sodium channels, and affecting dopaminergic and serotonergic transmission (1). The mechanism of VPA toxicity, including its effects on the liver, is not fully known. It is assumed that oxidative stress and/or reactive products of drug biotransformation are responsible for its hepatotoxicity (2). The aim of the study was to verify the hypothesis concerning the influence of valproic acid and its metabolite, 2-propyl-4-pentenoic acid (4-en VPA) on the antioxidant status of patients treated with (VPA-T) and poisoned with valproic acid (VPA-P). The VPA-P group was divided into patients with (VPA-Ptox) and without (VPA-Pnon) toxic symptoms observed during the hospitalization. Oxidative stress was assessed using markers, such as antioxidant potential (FRAP) and reduced and oxidised glutathione (GSH/GSSG) ratio were measured in the plasma of the study patients. The obtained results showed statistically significant differences between the concentrations of the drug and its active metabolite levels in the VPA-T and VPA-P groups. In the VPA-P group, the increase of the level of 4-en VPA in the plasma correlated with the increase of the concentration of the drug. The influence of VPA on the antioxidant balance in both groups of patients was demonstrated. The plasma antioxidant potential of FRAP decreased with increasing valproic acid concentrations in the VPA-Ptox group. The lowest concentrations of GSH/GSSG ratio were found in the VPA-Pnon group, without symptoms of intoxication during hospitalization.","PeriodicalId":7147,"journal":{"name":"Acta poloniae pharmaceutica","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2023-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41476084","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It has been the subject of extensive research for its potential in treating various diseases and as a functional food. The medical benefits of genistein are well documented in the literature. Several studies have been performed to better understand the mechanisms of its beneficiary effects on health and to improve its pharmacokinetic and pharmacodynamic parameters. It has been approved for relieving menopausal symptoms and has received attention for its use in the treatment of inflammatory and age-related disorders, cancer, metabolic illnesses, genetic disorders, and skin care. Genistein shows considerable similarity to endogenous estradiol. It is classified in the group known as phytoestrogens which exhibit properties corresponding to estrogen in the human body. The estrogenic activity resulting from the aforementioned similarity in the appearance of genistein and estradiol molecules makes it possible for genistein to act as both an estrogen agonist and antagonist, depending on the number of endogenous hormones present in the environment in which it is found and the type of tissue. The similarity of the chemical structure of genistein and estradiol and interactions occurring between estradiol and genistein and the amino acid binding site of the estrogen receptors were analyzed. Further controlled trials are needed to determine the efficacy and safety of genistein. Future research will focus on enhancing its bioavailability through structural modification and innovative delivery methods and conducting human trials to confirm its biological and pharmacological effects.","PeriodicalId":7147,"journal":{"name":"Acta poloniae pharmaceutica","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2023-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45600089","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Long-term administration of such therapy lead to liver dysfunction. As the cause of liver failure can be the size of lipid emulsion droplets, their reduction can positively affect the clinical condition of patients. This study aimed to develop and optimize the preparation process of intravenous lipid emulsions with reduced droplet size compared to commercially available formulations. The response surface methodology was applied to optimize the ultrasonic emulsification. The reduction of lipid droplet size was achieved by the use of a combination of 1.2% (w/w) soy phospholipids and various concentrations of Tween 80 (2, 3, and 4% (w/w)). The other variables were sonication amplitude and time of sonication. During the optimization process, fifteen soybeans oil-based intravenous lipid emulsions were developed. All formulations were characterized by the physicochemical properties appropriate for intravenous administration, i.e., MDD ranging from 119.1 ± 0.6 nm to 177.1 ± 2.1 nm, PdI below 0,219 ± 0,009. The pH and osmolarity ranged from 6.23 ± 0.01 to 6.58 ± 0 and from 328 ± 3 to 568 ± 8 mOsm/kg, respectively. The Box Behnken methodology allowed for optimizing the preparation of intravenous lipid emulsion using ultrasonic emulsification.","PeriodicalId":7147,"journal":{"name":"Acta poloniae pharmaceutica","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2023-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45112620","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study focuses on modulating the structure of curcumin derivatives or their analogues with the use of non-steroidal anti-inflammatory drugs (NSAIDs). The combinations of curcumin, its keto-blocked derivatives and monocarbonyl analogues with selected non-steroidal anti-inflammatory drugs (ibuprofen, naproxen) were obtained and characterized. The pyrazole, isoxazole, benzylidene derivatives as well as curcumin monocarbonyl analogues were used as substrates in the reactions with selected NSAIDs. As a result of the esterification of curcumin-type diphenol, the corresponding mono- and diester-type derivatives were also obtained and characterized. Moreover, the estimated values of binding affinities and the binding sites of docked derivatives were deduced from modeling studies were very favorable. Results obtained show the binding potential of curcumin and its analogs to the host-targeted proteins nucleocapsid phosphoprotein (PDB ID: 6VYO) structure.

This review provides an overview of the principles and applications of radiation sterilization, including the types of radiation sources used, the differences between them that may affect the efficacy of the process, and the regulatory requirements for radiation sterilization of active pharmaceutical ingredients and drug dosage forms. This review focuses on the analytical methods used to evaluate the effect of irradiation on drug substances. Finally, it discusses studies on radiation sterilization of various groups of drugs, including anthracyclines, β-lactam antibiotics, chloramphenicol and its derivatives, sulphonamides, antifungal drugs, β-blockers, nonsteroidal anti-inflammatory drugs, steroids, and others, and drug dosage forms.","PeriodicalId":7147,"journal":{"name":"Acta poloniae pharmaceutica","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2023-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45638367","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
