Mass spectrometry coupled with LC (UPLC-MS/MS) and gas chromatography (GC-MS/MS) measurements of the plasma concentration of boswellic acids and α-thujene at different post-administration time points followed by a single dose (400 mg) of U-BE and BFQ-20, to healthy volunteers (n = 16), offered 4-fold enhancement in the overall bioavailability of boswellic acids from BFQ-20, [area under the curve (AUC) (BFQ-20) = 9484.17 ± 767.82 ng * h/mL vs. AUC (U-BE) = 2365.87 ± 346.89 ng * h/mL], with the absorption maximum (T<sub>max</sub>) at 6.3 h post-administration and elimination half-life (T<sub>1/2</sub>) of 15.5 h (p < 0.001).

Mitochondria, which are essential for maintaining energy homeostasis within cells, can be targeted by drug delivery to regulate energy metabolism. However, there is a lack of research comparing how mitochondria control energy metabolism in different cell types derived from the neural crest. Understanding the effects of berberine (BBR), a compound that acts on mitochondria, on energy metabolism in neural crest-derived cells is important. This study reports how MITO-Porter, a mitochondria-targeted liposome, affects neuroblasts (Neuro2a cells) and normal human epidermal melanocytes (NHEMs) when loaded with BBR. We found that treatment with MITO-Porter containing BBR reduced mitochondrial respiration in Neuro2a cells, while it caused a slight increase in NHEMs. Additionally, the treatment shifted the ATP production pathway in Neuro2a cells to rely more on glycolysis, while in NHEMs, there was a slight decrease in the reliance on glycolysis. We also observed a significant decrease in ATP production in Neuro2a cells, while NHEMs showed a tendency to increase ATP production. Importantly, on the basis of the results of the Premix WST-1 assay, the study found that BBR treatment was not toxic to either cell type. It is important to take note of the varied effects of BBR treatment on different cell types derived from the neural crest. These findings necessitate attention when utilizing NHEMs as a cell model in the development of therapeutic strategies for neurodegenerative diseases, including the use of BBR for metabolic control.</p>","PeriodicalId":8955,"journal":{"name":"Biological & pharmaceutical bulletin","volume":"47 10","pages":"1726-1733"},"PeriodicalIF":1.7,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142494569","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}

IL-6 is a biomarker of sepsis and has been suggested to exacerbate its symptoms. We found that the intraperitoneal administration of CLP reduced IL-6 levels in the lungs and also improved hypothermia in mice with LPS-induced sepsis. CLP ameliorated kidney pathologies such as congestion and increased the survival rate of mice administered with a lethal dose of LPS. To reveal the mechanisms underlying the anti-inflammatory function of CLP, we analysed the intracellular signaling in LPS-treated RAW264.7 cells. CLP induced the phosphorylation of protein kinase B (Akt) and glycogen synthase kinase 3 (GSK3) and also increased the amount of nuclear factor erythroid-2-related factor 2 (Nrf2) in RAW264.7 cells with/without LPS. Wortmannin, an inhibitor of phosphoinositide 3-kinase (PI3K), reduced the upregulated phosphorylation levels of Akt and GSK3 and the increased amount of Nrf2.
