Context-dependent role of sirtuin 2 in inflammation

Neural Regeneration Research 2025年第3期20卷 682-694页

Sirtuin 2 is a member of the sirtuin family nicotinamide adenine dinucleotide(NAD~+)-dependent deacetylases, known for its regulatory role in different processes, including inflammation. In this context, sirtuin 2 has been involved in the modulation of key inflammatory signaling pathways and transcription factors by deacetylating specific targets, such as nuclear factor κB and nucleotide-binding oligomerization domain-leucine-rich-repeat and pyrin domain-containing protein 3(NLRP3). However, whether sirtuin 2-mediated pathways induce a pro-or an anti-inflammatory response remains controversial. Sirtuin 2 has been implicated in promoting inflammation in conditions such as asthma and neurodegenerative diseases, suggesting that its inhibition in these conditions could be a potential therapeutic strategy. Conversely, arthritis and type 2 diabetes mellitus studies suggest that sirtuin 2 is essential at the peripheral level and, thus, its inhibition in these pathologies would not be recommended. Overall, the precise role of sirtuin 2 in inflammation appears to be context-dependent, and further investigation is needed to determine the specific molecular mechanisms and downstream targets through which sirtuin 2 influences inflammatory processes in various tissues and pathological conditions. The present review explores the involvement of sirtuin 2 in the inflammation associated with different pathologies to elucidate whether its pharmacological modulation could serve as an effective strategy for treating this prevalent symptom across various diseases.

Hepatocytes targeting of cationic liposomes modified with soybean sterylglucoside and polyethylene glycol

引用

World Journal of Gastroenterology 2005年第32期11卷 4947-4952页

作者： Xian-Rong Qi Wen-Wei Yan Jing Shi department of pharmaceutics School of Pharmaceutical Sciences Peking University Beijing 100083 China

AIM： In this study, a hepatocyte-specific targeting technology was developed by modifying cationic liposomes with soybean sterylglucoside （SG） and polyethylene glycol （PEG）（C/SG/ PEG-liposomes）. METHODS： The liposomal transfection efficiencies in HepG2 2.2.15 cells were estimated with the use of fluorescein sodium （FS） as a model drug, by flow cytometry. The antisense activity of C/SG/PEG-liposomes entrapped antisense oligonucleotides （ODN） was determined as HBsAg and HBeAg in HepG2 2.2.15 cells by ELISA. The liposome uptake by liver and liver cells in mice was carried out after intravenous injection of 3H-labeled liposomes. RESULTS： C/SG-liposomes entrapped FS were effectively transfected into HepG2 2.2.15 cells in vitro. C/SG/PEG-Iiposomes entrapped ODN, reduced the secretion of both HBsAg and HBeAg in HepG2 2.2.15 cells when compared to free ODN. After in vivo injection of ^3H-labeled C/SG/PEG-liposomes, higher radiation accumulation was observed in the hepatocytes than non-parenchymal cells of the liver. CONCLUSION： C/SG/PEG-liposomes mediated gene transfer to the liver is an effective gene-delivery method for hepatocytes-specific targeting, which appears to have a potential for gene therapy of HBV infections.

The present study was to investigate pharmacognostical, phytochemical and pharmacological properties of extracts from stem of Cuscuta reflexa Roxb. Standard procedures have been followed to evaluate the pharmacognostical properties and preliminary screening of phytochemicals of Cuscuta reflexa Roxb. Albino Wistar rats(either sex) weighing 150–200 g were taken and made to acclimatize by providing them with the appropriate room conditions in the experimental room. Excision wound model has been selected for analgesic and wound healing activity for evaluating potential of the water-extract and ethanolic extract from the stem of Cuscuta reflexa Roxb. The macroscopic and microscopic studies showed the various characteristic features of stems. Preliminary screening of phytochemicals reveled that alkaloids, glycosides, flavonoids were the major groups of phytochemicals present in the successive extracts. Water and ethanolic extracts from stem of Cuscuta reflexa Roxb at 200 mg/kg and 400 mg/kg were able to alleviate pain and wounds. It is concluded that the stems of Cuscuta reflexa Roxb have a markedly therapeutic potential to heal wound and may provide the pharmacological basis for its folk uses.

作者： Neha Goyal Purva Thatai Bharti Sapra pharmaceutics Division Department of Pharmaceutical Sciences Punjabi University

In vivo skin permeation studies are considered gold standard but are difficult to perform and evaluate due to ethical issues and complexity of process involved. In recent past, a useful tool has been developed by combining the computational modeling and experimental data for expounding biological complexity. Modeling of percutaneous permeation studies provides an ethical and viable alternative to laboratory experimentation. Scientists are exploring complex models in magnificent details with advancement in computational power and technology. Mathematical models of skin permeability are highly relevant with respect to transdermal drug delivery, assessment of dermal exposure to industrial and environmental hazards as well as in developing fundamental understanding of biotransport *** review focuses on various mathematical models developed till now for the transdermal drug delivery along with their applications.

Flavonoids are widely used in industry for the prevention of various diseases. In daily life we are directly in touch with flavonoids due to their presence in different beverages, fruits and vegetables. Flavonoids are mainly used as a coloring agent in plants, antioxidant and nutritional food for human. Flavonoids have explicit role in UV filtration, symbiotic nitrogen fixation and floral pigmentation. Flavonoids have potential for different biological activities like chelation of metals, decreasing platelets aggregation and cell signaling etc.

Degradation rates and products of fluticasone propionate in alkaline solutions

Journal of pharmaceutical Analysis 2017年第5期7卷 297-302页

The apparent degradation rate constant of fluticasone propionate(FLT) in 0.1 M NaOH:methanol=1:1 at 37 °C was previously reported to be 0.169 ± 0.003 h^(-1), and four degradation products(products 1–4) were observed in the solution. The aims of the present study were to assess the degradation rates of FLT in other alkaline solutions and clarify the chemical structures of the four degradation products in order to obtain basic data for designing an enema for inflammatory bowel disease. The apparent degradation rate constants in 0.05 M NaOH and 0.1 M NaOH:CH_3CN=1:1 were 0.472 ± 0.013 h^(-1) and 0.154 ± 0.000 h^(-1)(n=3), respectively. The chemical structures of products 1–4 in 0.1 M NaOH:methanol=1:1 were revealed by nuclear magnetic resonance(NMR)and mass spectrometry data. The chemical structure of products 2 was that the 17-position of the thioester moiety of FLT was substituted by a carboxylic acid. The degradation product in 0.1 M NaOH:CH_3CN=1:1 was found to be product 2 based on ~1H NMR data. The degradation product in 0.05 M NaOH was considered to be product 2 based on the retention time of HPLC. These results are useful for detecting the degradation products of FLT by enzymes of the intestinal bacterial flora in the large intestine after dosing FLT as an enema.
