Abstract
Gastric ulcer is one of the most frequent gastrointestinal ailments worldwide. Indomethacin, one of the most potent NSAIDs, suffers undesirable ulcerogenic activity. Caffeic acid phenethyl ester (CAPE) has known health benefits. The current study examined the potential of CAPE to combat indomethacin-induced gastric ulcers in rats. Animals were randomized into 5 groups: control, Indomethacin (50 mg/kg) mg/kg), Indomethacin + CAPE (5 mg/kg/day), Indomethacin + CAPE (10 mg/kg), and Indomethacin + Omeprazole (30 mg/kg). CAPE prevented the rise in ulcer index, attenuated histopathological changes and preserved gastric mucin concentration. CAPE efficiently significantly prevented accumulation of malondialdehude (MDA) and prevented exhaustion of the enzymatic activities of catalase (CAT) and superoxide dismutase (SOD). Further, CAPE prevented the rise in the expression of tumor necrosis factor-α (TNF-α), cyclo-oxygenase-2 (COX-2) and nuclear factor kapp-B (NFκB). This was associated with down-regulation of Bax and up-regulation of Bcl-2 mRNA. Finally, CAPE prevented induced indomethacin-induced decrease in heat shock protein 70 (HSP70) in gastric tissues. In conclusion, CAPE possesses the ability to prevent indomethacin-induced gastric ulcer in rats. This involves, at least partially, antioxidation, anti-inflammation, anti-apoptosis and enhancement of HSP70 expression.

[PMID: 38337674 PMCID: PMC10857084 DOI: 10.3390/nu16030389] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2023] [Revised: 01/07/2024] [Accepted: 01/24/2024] [Indexed: 02/12/2024] Open
Abstract
Gastritis, one of the most common gastrointestinal disorders, damages the stomach lining as it causes a disproportion between the protective and ruinous factors of the gastric system. Cabbage (CB) is widely used to treat gastric lesions but requires the addition of natural sweeteners to counteract its distinct bitter taste. Therefore, this study sought to determine whether the combination of chestnut honey (CH)-which is known for its dark brown color and high kynurenic acid (KA) content-or KA-increased CH (KACH) with CB (CH + CB or KACH + CB) exerts synergistic effects for improving both taste and efficacy. Before confirming the gastroprotective effects in indomethacin (INDO)-induced rats, the anti-inflammatory activities of CH + CB and KACH + CB were assessed in lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages. As a result, treatment with either CH + CB or KACH + CB downregulated pro-inflammatory cytokine levels in LPS-stimulated RAW 264.7 macrophages by regulating the translocation of nuclear factor kappa B. Furthermore, both CH + CB and KACH + CB not only enhanced the levels of antioxidant enzymes but also triggered the activation of nuclear factor erythroid-related factor 2. Based on these effects, CH + CB or KACH + CB effectively protected the gastric mucosa in INDO-induced rats. Therefore, this study suggests that CH + CB and KACH + CB exert stronger gastroprotective effects when used together.

AAPS PharmSciTech 2023; 24:243. [PMID: 38030940 DOI: 10.1208/s12249-023-02693-7] [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: 08/07/2023] [Accepted: 10/31/2023] [Indexed: 12/01/2023] Open
Abstract
Kaempferia galanga volatile oil (KVO), the main effective component of the medicinal plant Kaempferia galanga L., possesses a variety of pharmacological activities such as anti-inflammatory, antioxidant, and anti-angiogenic activities and has therapeutic potential for gastric ulcer (GU). However, poor solubility as well as instability limits the clinical application of KVO. In this study, K. galanga volatile oil self-microemulsion solids (KVO-SSMEDDS) were prepared to improve its bioavailability and stability, and the therapeutic effects were evaluated in a rat model with GU. The ratio of oil phase, emulsifier, and co-emulsifier in the KVO-SMEDDS prescription were optimized by plotting the pseudo-ternary phase diagram with the star point design-response surface method. Based on the optimal prescription, self-microemulsifying drug delivery system (SMEDDS) was prepared as solid particles (S-SMEDDS). The prepared KVO-SSMEDDS had a rounded and non-adhesive appearance, formed an O/W emulsion after dissolution in water, and had a uniform particle size distribution with good stability and solubility. It was administered to GU model animals, and the results showed that a certain dose of KVO-SSMEDDS solution could increase the content of gastric mucosal protective factors PGE2, TGF-α, and EGF in gastric tissues and serum, and the expression of inflammatory factors IL-8 and TNF-α was downregulated. Meanwhile, the expression of the NF-κB/COX-2 pathway proteins was inhibited. In conclusion, the prepared KVO-SSMEDDS has good dispersion, solubility, and stability and has a therapeutic effect on rats with GU.
