Antiallergic Effect of the Alpha-Cyclodextrin Moringin Complex in Rat Basophilic Leukaemia (RBL-2H3) Cell Line. Adv Pharmacol Pharm Sci 2024; 2024:8885068. [PMID: 39104427 PMCID: PMC11300081 DOI: 10.1155/2024/8885068] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2023] [Revised: 03/19/2024] [Accepted: 06/25/2024] [Indexed: 08/07/2024] Open
Abstract
Allergic diseases (ADs) are a major concern when it comes to public well-being. Moringa oleifera Lam is a tropical plant that is used in traditional medicine due to the presence of isothiocyanate. The present study investigated the antiallergic properties of 4-(α-L-rhamnopyranosyloxy)-benzyl isothiocyanate or moringin isolated from Moringa oleifera seeds in the form of alpha-cyclodextrin-moringin (α-CD/MG) complex on rat basophilic leukaemia (RBL-2H3) cell line at both the early and late stages of an allergic reaction. The α-CD/MG complex was initially elucidated using nuclear magnetic resonance (NMR) followed by the 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium inner salt proliferation assay to evaluate the cytotoxicity and cell viability with respect to ketotifen fumarate (KF) and α-CD/MG. The release of beta-hexosaminidase (β-hexosaminidase) and histamine was used to determine the level of inhibition in the early stage while the suppression of the release of prostaglandin (PGD2), tumour necrosis factor-alpha (TNF-α), and interleukin (IL-4) was considered in the late stage. Higher concentrations of α-CD/MG (5 μM, p < 0.001) in mast cell degranulation significantly inhibited the expression of β-hexosaminidase, histamine, TNF-α, PGD2, and IL-4 in both the early and late stages. Thus, α-CD/MG can potentially be developed as an antiallergic drug as it has the ability to inhibit allergic responses in the late and early stages.

Effects of a novel roflumilast and formoterol fumarate dry powder inhaler formulation in experimental allergic asthma. Int J Pharm 2020; 588:119771. [PMID: 32805379 DOI: 10.1016/j.ijpharm.2020.119771] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2020] [Revised: 08/10/2020] [Accepted: 08/11/2020] [Indexed: 12/14/2022]
Abstract
In this study we aimed to develop a roflumilast (R) and formoterol fumarate (F) dry powder inhaler formulation (DPI) incorporating HPβCD by spray drying and evaluated if it attenuates the inflammatory process and improves lung function in a murine model of ovalbumin induced allergic asthma. The DPI was characterized by powder X-ray diffraction, thermal analysis, scanning electron microscopy, particle size, density, specific surface area and dynamic vapor sorption analyses. In vitro deposition studies were performed using a NGI, while transepithelial permeability and in vivo effects on lung mechanics and inflammation in a model of allergic asthma were also assessed. The R:F formulation was amorphous with high glass transition temperatures, comprised of wrinkled particles, had low bulk and tapped densities, high surface area, suitable particle size for pulmonary delivery and exhibited no recrystallization even at high relative humidities. MMAD were statistically similar of 4.22 ± 0.19 and 4.32 ± 0.13 µm for F and R, respectively. Fine particle fractions (<5 µm) were of more than 50% of the emitted dose. The R:F formulation led to reduced eosinophil infiltration and airway collagen fiber content, yielding decreased airway hyperresponsiveness. In the current asthma model, the R:F formulation combination decreased inflammation and remodeling, thus improving lung mechanics.

Abstract
BACKGROUND AND AIMS Mast cell activation interferes with the effects of allergen-specific immunotherapy (SIT). Galectin-1 (Gal-1) is capable of regulating immune cells' functions. This study tests the hypothesis that administration of Gal-1 promotes and prolongs the efficacy of SIT via suppressing mast cell activation. METHODS An intestinal allergy mouse model was developed. The coadministration of SIT and Gal-1 on suppression of the allergic responses, prevention of mast cell activation, and generation of antigen-specific regulatory T cells (Treg) in the intestine was observed in sensitized mice. RESULTS The coadministration of Gal-1 and SIT markedly suppressed the allergic responses in the mouse intestine vs the use of either SIT alone or Gal-1 alone. The Gal-1 binds to the IgE/FcɛRI complexes on the surface of mast cells to prevent mast cell activation during SIT. Gal-1 promoted the SIT-generated allergen-specific Tregs in the intestine of sensitized mice. Coadministration of Gal-1 and SIT significantly enhanced the efficacy of immunotherapy in suppressing allergic responses in the intestine, which lasted for at least for 12 months. CONCLUSIONS Long-term effects of specific immunotherapy on intestinal allergy can be achieved with Gal-1/SIT therapy by inhibiting mast cell activation and facilitating Treg development.
