A water-soluble preparation for intravenous administration of isorhamnetin and its pharmacokinetics in rats. Chem Biol Interact 2024; 396:111064. [PMID: 38768772 DOI: 10.1016/j.cbi.2024.111064] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2024] [Revised: 04/22/2024] [Accepted: 05/18/2024] [Indexed: 05/22/2024]
Abstract
Flavonoids are considered as health-protecting food constituents. The testing of their biological effects is however hampered by their low oral absorption and complex metabolism. In order to investigate the direct effect(s) of unmetabolized flavonoid, a preparation in a biologically friendly solvent for intravenous administration is needed. Isorhamnetin, a natural flavonoid and a human metabolite of the most frequently tested flavonoid quercetin, has very low water solubility (<3.5 μg/mL). The aim of this study was to improve its solubility to enable intravenous administration and to test its pharmacokinetics in an animal model. By using polyvinylpyrrolidone (PVP10) and benzalkonium chloride, we were able to improve the solubility approximately 600 times to 2.1 mg/mL. This solution was then administered intravenously at a dose of 0.5 mg/kg of isorhamnetin to rats and its pharmacokinetics was analyzed. The pharmacokinetics of isorhamnetin corresponded to two compartmental model with a rapid initial distribution phase (t1/2α: 5.7 ± 4.3 min) and a slower elimination phase (t1/2β: 61 ± 47.5 min). Two sulfate metabolites were also identified. PVP10 and benzalkonium did not modify the properties of isorhamnetin (iron chelation and reduction, and cell penetration) substantially. In conclusion, the novel preparation reported in this study is suitable for future testing of isorhamnetin effects under in vivo conditions.

Abstract
Quercetin, as a representative flavonoid, is widely present in daily diet and has been developed as a dietary supplement due to its beneficial physiological activities. However, the application of quercetin is limited due to its poor water solubility and extensive metabolism. So far, the nano-drug delivery systems designed to improve its bioavailability generally have the shortcomings of low drug loading content and difficulty in industrial production. In order to tackle these problems, quercetin supersaturated drug delivery system (QSDDS) was successfully prepared using solvent method, for which PVP K30 was employed as a crystallization and precipitation inhibitor to maintain the supersaturated state of quercetin in aqueous system. The obtained QSDDS, with a relative high drug loading content of 13%, could quickly disperse in water and form colloidal system with the mean particle size of about 200 nm, meanwhile induce the generation of supersaturated quercetin solution more than 12 h. In vivo pharmacokinetic study proved that QSDDS achieved a high absolute bioavailability of 36.05%, 10 times as that of physical quercetin suspension, which was dose-dependent with higher bioavailability at higher dose. Considering the simple preparation method, QSDDS provided a feasible strategy and a simple way to improve oral absorption of insoluble flavonoids.

Abstract
Alzheimer's Disease (AD) is a progressive neurodegenerative disorder impairing cognition and memory in the elderly. This disorder has a complex etiology, including senile plaque and neurofibrillary tangle formation, neuroinflammation, oxidative stress, and damaged neuroplasticity. Current treatment options are limited, so alternative treatments such as herbal medicine could suppress symptoms while slowing cognitive decline. We followed PRISMA guidelines to identify potential herbal treatments, their associated medicinal phytochemicals, and the potential mechanisms of these treatments. Common herbs, including Ginkgo biloba, Camellia sinensis, Glycyrrhiza uralensis, Cyperus rotundus, and Buplerum falcatum, produced promising pre-clinical results. These herbs are rich in kaempferol and quercetin, flavonoids with a polyphenolic structure that facilitate multiple mechanisms of action. These mechanisms include the inhibition of Aβ plaque formation, a reduction in tau hyperphosphorylation, the suppression of oxidative stress, and the modulation of BDNF and PI3K/AKT pathways. Using pre-clinical findings from quercetin research and the comparatively limited data on kaempferol, we proposed that kaempferol ameliorates the neuroinflammatory state, maintains proper cellular function, and restores pro-neuroplastic signaling. In this review, we discuss the anti-AD mechanisms of quercetin and kaempferol and their limitations, and we suggest a potential alternative treatment for AD. Our findings lead us to conclude that a polyherbal kaempferol- and quercetin-rich cocktail could treat AD-related brain damage.

Abstract
The poor water solubility of numerous novel drug candidates presents significant challenges, particularly in terms of oral administration. This limitation can result in various undesirable clinical implications, such as inter-patient variability, poor bioavailability, difficulties in achieving a safe therapeutic index, increased costs, and potential risks of toxicity or inefficacy. Biopharmaceutics Classification System (BCS) class II drugs face particular hurdles due to their limited solubility in the aqueous media of the gastrointestinal tract. In such cases, parenteral administration is often employed as an alternative strategy. To address these challenges, nanosuspension techniques offer a promising solution for enhancing drug solubility and overcoming oral delivery obstacles. This technique has the potential to bridge the gap between drug discovery and preclinical use by resolving problematic solubility. This literature review has delved into contemporary nanosuspension preparation technologies and the incorporation of stabilizing ingredients within the formulation. Furthermore, the manuscript explores nanosuspension strategies for both oral and parenteral/other delivery routes, and separate discussions have been presented to establish a suitable flow that addresses the challenges and strategies relevant to each administration method.

Abstract
To improve the solubility and anti-hyperuricemia activity of the insoluble natural flavonoid isorhamnetin (ISO), an isorhamnetin phospholipid complex (ISO-PC) was prepared. ISO-PC was prepared through solvent evaporation and its prescription process was optimized. The formation of ISO-PC was verified via multiple characterization methods. Parameters such as drug loading, solubility, octanol-water partition coefficient, stability, and in vivo anti-hyperuricemia activity of ISO-PC were investigated. The complexation efficiency of ISO-PC was 95.1% ± 0.56%. The characterization results confirmed that ISO-PC was bound by intermolecular interactions between ISO and phospholipids. Compared to ISO, the solubility of ISO-PC in water and 1-octanol increased by 122 and 16.5 times, respectively. Additionally, the octanol-water partition coefficient decreased to 1.08. Pharmacodynamic studies have reported that ISO-PC has a more significant effect on reducing serum uric acid levels and renal protection. In conclusion, the findings of this study suggested that ISO-PC could be used as a promising formulation to improve the solubility and the anti-hyperuricemia activity of ISO.

Abstract
The aim of this study was to develop a gambogic acid-loaded mixed micelles (GA-M) system, using Kolliphor HS15 and lecithin, for enhancement of oral bioavailability. GA-M was prepared using the thin film hydration method, and particle size and zeta potential indexes were used to determine the optimized formulation was optimized with taking particle size, zeta potential as indexes. The optimal GA-M system had a mean particle size in the nanometer range (87.22 ± 0.68 nm) and zeta potential greater than 20 mV in magnitude (-21.63 ± 1.69 mV) at a 1:1 proportion of HS15: lecithin. Additionally, the carriers had a high entrapment efficiency (98.32 ± 3.52%) and drug loading (4.68 ± 0.17%). Furthermore, the in vitro GA release characteristics followed first-order kinetics, suggesting that release of the molecule was achieved both by medium diffusion and structural erosion. Transport elucidation in Caco-2 cells demonstrated that the efflux ratio of encapsulated GA was dramatically decreased from 1.42 to 0.76, and pharmacokinetic studies showed that the oral bioavailability of GA-M was 2.3 times higher than that of free GA, indicating that HS15/lecithin mixed micelles could promote absorption in the gastrointestinal tract. Overall, these results present a micelle system suitable for oral delivery, with increased solubility and oral bioavailability of GA.

JOURNAL OF ETHNOPHARMACOLOGY 2022; 292:115225.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The therapeutic properties of Hippophae rhamnoides L. were already known in ancient Greece as well as in Tibetan and Mongolian medicine. Modern studies have indicated that Hippophae rhamnoides L. fermentation liquid protected against alcoholic fatty liver disease (AFLD). However, the underlying mechanism of Hippophae rhamnoides L. flavonoids extract (HLF) treating AFLD remains elusive. AIM OF THE STUDY This study aimed to investigate the hepatoprotective effect of HLF in mice with AFLD and the interaction between AFLD and gut microbiota. MATERIALS AND METHODS Chemical constituents of HLF were analyzed by Liquid Chromatography-Ion Trap-ESI-Mass Spectrometry. The Hepatoprotective effect of HLF was evaluated in mice with AFLD induced by alcohol (six groups, n = 10) daily at doses of 0.1, 0.2, and 0.4 g/kg for 30 consecutive days. At the end of experiment, mice were sacrificed and the liver, serum and feces were harvested for analysis. The liver histological changes were observed by H&E staining and oil red O staining. Moreover, the alterations of fecal microflora were detected by 16S rRNA gene sequencing. The inflammatory related genes were determined by qRT-PCR and western blotting respectively. RESULTS The results showed that the oral administration of HLF remarkably alleviated hepatic lipid accumulation by decreasing the levels of ALT, AST, TG and TC. The levels of TNF-α, TGF-β, and IL-6 were also reduced after treatment with HLF. Meanwhile, the protein and mRNA expression of NF-kB p65, MAPK p38 and TAK-1 in the liver of mice with AFLD were all reduced by HLF compared with model group. Furthermore, the 16S rRNA gene sequencing analysis demonstrated that HLF treatment can help restore the imbalance of intestinal microbial ecosystem and reverse the changes in Fimicutes/Bacterodietes, Clostridiales, Lachnospiraceae, S24-7, and Prevotella in mice with AFLD. CONCLUSION HLF can effectively ameliorate liver injury in mice with AFLD, and regulate the composition of gut microbiota. Its regulatory mechanism may be related to TAK1/p38MAPK/p65NF-κB pathway. This study may provide novel insights into the mechanism of HLF on AFLD and a basis for promising clinical usage.

Abstract
Sea buckthorn (Hippophae rhamnoides L., SBT) is being used as a folk medicine for their diverse medicinal properties. Flavonoids are generally considered as the main bioactive and characteristic ingredients in SBT. This review was conducted using a comprehensive literature search on the chemical components, quality control, pharmacokinetics of flavonoids from SBT (FSBT). Particularly, we highlighted the therapeutic potential in metabolic diseases and clinical applications of FSBT. More than 95 flavonoids have been identified from SBT. Although the oral bioavailability of FSBT was relatively low, FSBT displays significant effect on the regulation of metabolism to ameliorate metabolic disorders and their complications. There is a heightened need to explore the bioactive compounds in SBT and mechanism(s) of action of FSBT in order to fully understand the pathways of their activities. PRACTICAL APPLICATIONS: For years, due to the increasing emergence of metabolic syndrome and diverse functions of FSBT in regulating metabolism, they can be efficiently utilized for human health and have an urgent need to become a hotspot for research. This review will broaden the understanding of FSBT, providing some directions for further development and expanding the therapeutic applications of FSBT.
