APC 366
Based on 1 Customer Validation
APC 366 is a selective inhibitor of mast cell tryptase (Ki=7.1 μM). APC 366 inhibits antigen-induced early asthmatic response (EAR), late asthmatic response (LAR), and bronchial hyperresponsiveness (BHR) in a sheep model of allergic asthma.

Ovalbumin-Induced Allergic Airway Inflammation
Ovalbumin-induced allergic airway inflammation is a mouse model in which systemic sensitization to ovalbumin, usually with aluminum hydroxide adjuvant, is followed by airway ovalbumin challenge to induce allergic airway inflammation, eosinophil recruitment, mucus production, serum antigen-specific IgE, Th2 cytokine responses, and airway hyperresponsiveness to methacholine. The model is used to study allergen-driven airway inflammation and asthma-like immune responses, but it does not reproduce every feature of human asthma. The main readouts are bronchoalveolar lavage fluid cellularity, lung histopathology, airway hyperresponsiveness, serum OVA-specific IgE, and cytokines such as IL-4, IL-5, and IL-13 in bronchoalveolar lavage fluid or lung samples. Eosinophilia and Th2 cytokines reflect allergic type 2 inflammation, while methacholine responsiveness provides a functional airway-reactivity endpoint.
