Antiallergic Effect of the Alpha-Cyclodextrin Moringin Complex in Rat Basophilic Leukaemia (RBL-2H3) Cell Line

Area of Science:

• Pharmacology and Toxicology
• Natural Product Chemistry

Background:

• Allergic diseases (ADs) pose a significant public health challenge.
• Moringa oleifera Lam, a tropical plant, contains isothiocyanates with potential medicinal properties.

Purpose of the Study:

• To investigate the antiallergic properties of moringin (alpha-cyclodextrin complex, α-CD/MG) from Moringa oleifera.
• To evaluate the efficacy of α-CD/MG in inhibiting both early and late stages of allergic reactions.

Main Methods:

• Isolated and characterized α-CD/MG complex using Nuclear Magnetic Resonance (NMR).
• Assessed cytotoxicity and cell viability using MTT assay.
• Measured inhibition of beta-hexosaminidase and histamine release (early stage).
• Quantified suppression of prostaglandin D2 (PGD2), tumor necrosis factor-alpha (TNF-α), and interleukin-4 (IL-4) (late stage).

Main Results:

• α-CD/MG complex showed no significant cytotoxicity.
• Higher concentrations of α-CD/MG (5 μM) significantly inhibited mast cell degranulation.
• α-CD/MG effectively suppressed the release of key allergic mediators (β-hexosaminidase, histamine, TNF-α, PGD2, IL-4) in both early and late stages.

Conclusions:

• The α-CD/MG complex demonstrates potent antiallergic properties.
• α-CD/MG has the potential for development into a novel antiallergic therapeutic agent.
