Unearthing the Potential Therapeutic Effects of Oxyresveratrol Based on Intrinsic Links between Pharmacological Effects: Implications for the Gut-Liver-Brain Axis

Oxyresveratrol is a stilbene compound with a simple chemical structure and various therapeutic potentials. This study summarized and analyzed the multiple pharmacological effects and mechanisms of oxyresveratrol, identifying its prominent performance in neuroprotection, hepatoprotection, and anti-inflammatory activities in the intestines. By integrating the pharmacological effects of oxyresveratrol with insights from the network pharmacology and molecular docking of its interactions with targets linked to gut-liver-brain axis disorders, it has been shown that oxyresveratrol may hold promise for the treatment of gut-liver-brain axis-related disorders. The synergistic effect between various mechanisms has inspired further research and the development of oxyresveratrol's application value.

Beneficial action of cinnamic acid against ovarian cancer via network pharmacology analysis and the pharmacological activity assessment

Naturally occurring cinnamic acid (CA) shows the beneficial potential in the suppression of ovarian cancer (OC). Currently, the in-depth molecular mechanisms of CA to suppress OC are still undescribed entirely. Thus, our research used the preclinical methodology through network pharmacology approach and pharmacological evaluation in vitro to unshroud the anti-OC targets and mechanisms of CA. Our data primarily identified 202 CA targets and 495 OC targets, and additional 45 shared targets in CA and OC were screened as presented in interaction network map. All 11 core targets in CA against OC were identified completely. The enrichment analysis of core targets revealed the biological functions and molecular mechanisms of CA against OC in details, including metabolic recombination and immune microenvironment regulation. Additionally, pharmacological evaluation data in vitro suggested that CA inhibited human OC cell proliferation in the time- and dose-dependent manners. In conclusion, CA can exert antineoplastic effects against OC effectively, and the pharmacological functions may directly actualize through a multi-target and multi-pathway avenue for suppressing OC.

Assessment of disease control rate and safety of sorafenib in targeted therapy for advanced liver cancer

OBJECTIVE

The clinical efficacy and safety of sorafenib in patients with advanced liver cancer (ALC) were evaluated based on transarterial chemoembolization (TACE).

METHODS

92 patients with ALC admitted to our hospital from May 2020 to August 2022 were randomly rolled into a control (Ctrl) group and an observation (Obs) group, with 46 patients in each. Patients in the Ctrl group received TACE treatment, while those in the Obs group received sorafenib molecular targeted therapy (SMTT) on the basis of the treatment strategy in the Ctrl group (400 mg/dose, twice daily, followed by a 4-week follow-up observation). Clinical efficacy, disease control rate (DCR), survival time (ST), immune indicators (CD3+, CD4+, CD4+/CD8+), and adverse reactions (ARs) (including mild fatigue, liver pain, hand-foot syndrome (HFS), diarrhea, and fever) were compared for patients in different groups after different treatments.

RESULTS

the DCR in the Obs group (90%) was greatly higher to that in the Ctrl group (78%), showing an obvious difference (P < 0.05). The median ST in the Obs group was obviously longer and the median disease progression time (DPT) was shorter, exhibiting great differences with those in the Ctrl group (P < 0.05). Moreover, no great difference was observed in laboratory indicators between patients in various groups (P > 0.05). After treatment, the Obs group exhibited better levels in all indicators. Furthermore, the incidence of ARs in the Obs group was lower and exhibited a sharp difference with that in the Ctrl group (P < 0.05).

CONCLUSION

SMTT had demonstrated good efficacy in patients with ALC, improving the DCR, enhancing the immune response of the body, and reducing the incidence of ARs, thereby promoting the disease outcome. Therefore, it was a treatment method worthy of promotion and application.

Gastrointestinal Cancer Therapeutics via Triggering Unfolded Protein Response and Endoplasmic Reticulum Stress by 2-Arylbenzofuran

Gastrointestinal cancers are a major global health challenge, with high mortality rates. This study investigated the anti-cancer activities of 30 monomers extracted from Morus alba L. (mulberry) against gastrointestinal cancers. Toxicological assessments revealed that most of the compounds, particularly immunotoxicity, exhibit some level of toxicity, but it is generally not life-threatening under normal conditions. Among these components, Sanggenol L, Sanggenon C, Kuwanon H, 3'-Geranyl-3-prenyl-5,7,2',4'-tetrahydroxyflavone, Morusinol, Mulberrin, Moracin P, Kuwanon E, and Kuwanon A demonstrate significant anti-cancer properties against various gastrointestinal cancers, including colon, pancreatic, and gastric cancers. The anti-cancer mechanism of these chemical components was explored in gastric cancer cells, revealing that they inhibit cell cycle and DNA replication-related gene expression, leading to the effective suppression of tumor cell growth. Additionally, they induced unfolded protein response (UPR) and endoplasmic reticulum (ER) stress, potentially resulting in DNA damage, autophagy, and cell death. Moracin P, an active monomer characterized as a 2-arylbenzofuran, was found to induce ER stress and promote apoptosis in gastric cancer cells, confirming its potential to inhibit tumor cell growth in vitro and in vivo. These findings highlight the therapeutic potential of Morus alba L. monomers in gastrointestinal cancers, especially focusing on Moracin P as a potent inducer of ER stress and apoptosis.

Recent progress in nanotechnology-based drug carriers for resveratrol delivery

Resveratrol is a polyphenol with diverse pharmacological activities, but its clinical efficacy is limited due to low solubility/permeability, light-induced isomerization, auto-oxidation, and rapid metabolism. Nanodelivery systems, such as liposomes, polymeric nanoparticles, lipid nanocarriers, micelles, nanocrystals, inorganic nanoparticles, nanoemulsions, protein-based nanoparticles, exosomes, macrophages, and red blood cells (RBCs) have shown great potential for improving the solubility, biocompatibility, and therapeutic efficacy of resveratrol. This review comprehensively summarizes the recent advances in resveratrol nanoencapsulation and describes potential strategies to improve the pharmacokinetics of existing nanoformulations, enhance targeting, reduce toxicity, and increase drug release and encapsulation efficiency. The article also suggests that in order to avoid potential safety issues, resveratrol nanoformulations must be tested in vivo in a wide range of diseases.

Iron-Based Nanoparticles Applied to Evaluate MRI Diagnosis and Treatment of Liver Cancer Treated with Apatinib

Objective: To investigate the value of iron-based nanoparticles in evaluating the magnetic resonance imaging (MRI) diagnosis and treatment of liver cancer treated with apatinib. Methods: Apatinib treatment and MRI were performed in patients with primary liver cancer. The characteristics of liver tissue sections and biodistribution in mice after injection of Fe2O3-PEG and iron oxide nanoparticles (Fe2O3-pep) were analyzed, and the MRI characteristics and magnetic resonance signals of Fe2O3-PEG and Fe2O3-pep nanoparticles were compared. Results: Fe2O3-PEG and Fe2O3-pep had little effect on the activity of human normal hepatocytes. There was no significant difference in liver tissue sections between mice injected with Fe2O3-PEG and Fe2O3-pep nanoparticles. The Fe2O3-PEG and Fe2O3-pep in the liver organs of mice were 11.3 and 9.7, which were significantly higher than those in other organs. At 12 hours and 24 hours after injection of Fe2O3-pep and Fe2O3-PEG nanoparticles, the signal at the tumor site decreased on T2WI images, the maximum contrast of magnetic resonance images was enhanced at 12 hours after injection, and the signal decrease was more significant in the group injected with Fe2O3-pep nanoparticles. Conclusion: Fe2O3-pep has higher tumor targeting and has positive application value in evaluating MRI diagnosis and treatment of liver cancer.
