Abstract: Introduction: Aurantio-obtusin is a trihydroxyanthraquinone found in the seeds of Cassia tora and Cassia obtusifolia. Its neuroprotective, anti-inflammatory, anti-allergic, and antioxidant potential has been documented in multiple studies. While previous reports mention its potential as an antiasthma agent, its effects on allergen‐induced airway inflammation have not been explored. Method: Our study reports on the mechanisms by which aurantio-obtusin exerts its effects on underlying inflammation in experimentally‐induced allergic asthma. The effect of aurantio-obtusin pretreatment on molecular and histological changes in guinea pig lungs when challenged with aerosolized ovalbumin was assessed. Results: Our results showed that aurantio-obtusin significantly reduced ovalbumin (OVA)‐induced increase in serum OVA-specific immunoglobulin E (OVA‐sIgE) and intercellular adhesion molecule (ICAM)‐1. Aurantio‐obtusin further suppressed inflammatory cytokine expression (IL‐8, TNF‐α, IL‐6 and thymic stromal lymphopoietin) as well as malondialdehyde, a product of oxidative stress in bronchial lavage. The histopathological assessment showed a reduced transit of inflammatory cells and reduced deposition of collagen in the lungs of aurantio-obtusin-treated guinea pigs. Conclusion: Overall, the data suggests that aurantio-obtusin mitigated ovalbumin‐induced airway inflammation by impeding the production of OVAsIgE and suppressing levels of key pro‐inflammatory cytokines. Our findings suggest that aurantio-obtusin has potential benefits in the management of allergic airway inflammation in type 2 asthma.

Abstract: Allergic rhinitis (AR) is a growing global health concern. Despite being non-fatal, it has a detrimental effect on people′s quality of life and poses a significant economic burden. In this study, we aimed to evaluate the anti-allergic effects of against ovalbumin-induced murine model of allergic rhinitis. was administered to rats orally after sensitization to ovalbumin. Results of the study suggested that causes a significant reduction in nose rubs and sneeze as compared to the vehicle-treated disease control group. The treated group showed a dose-dependent significant reduction in serum TNF-α, IL-4, and IL-6 levels as well as levels in the nasal mucosa. Addnl., it decreased neutrophil and eosinophil numbers in blood of AR rats′. In the nasal tissues of the vehicle-treated rats that were subjected to an OVA challenge, the histol. of the nasal mucosa of AR rats revealed aberrant histol. changes. A variety of histol. abnormalities, including vascular congestion in the nasal mucosa, substantial inflammatory cell infiltration, and obvious alveolar wall edema were present. In the rats treated with , these characteristics were reversed. Collectively, the findings suggests that could be used to enhance current AR treatment approaches.

Dissolving Methods
Please choose the appropriate dissolution scheme according to your animal administration guide.For the following dissolution schemes, clear stock solution should be prepared according to in vitro experiments, and then cosolvent should be added in turn:

in order to ensure the reliability of the experimental results, the clarified stock solution can be properly preserved according to the storage conditions; The working fluid for in vivo experiment is recommended to be prepared now and used on the same day;

The percentage shown in front of the following solvent refers to the volume ratio of the solvent in the final solution; If precipitation or precipitation occurs in the preparation process, it can be assisted by heating and/or ultrasound.
