Biological Activities of Morita-Baylis-Hillman Adducts (MBHA).

Background: The Morita-Baylis-Hillman reaction (MBHR) is considered one of the most powerful and versatile methodologies used for carbon-carbon bond formation. The reaction is defined as the condensation between an electrophilic carbon sp² and the α position of an olefin, carrying an electron-withdrawing group, in the presence of a catalyst. The advantages of the reaction are the high atom economy and mild reaction conditions.

Milonine attenuates the lipopolysaccharide-induced acute lung injury in mice by modulating the Akt/NF-κB signaling pathways.

Acute lung injury is an inflammation that triggers acute respiratory distress syndrome with perialveolar neutrophil infiltration, alveolar-capillary barrier damage, and lung edema. Activation of the toll-like receptor 4 complex (TLR4/MD2) and its downstream signaling pathways are responsible for the cytokine storm and cause alveolar damage. Due to the complexity of this pulmonary inflammation, a defined pharmacotherapy has not been established.

Combined allergic rhinitis and asthma syndrome (CARAS).

Combined allergic rhinitis and asthma syndrome (CARAS) is a concept of "one airway - one disease" or "unified airway disease ". The upper and lower airway inflammation characterizes allergic rhinitis and asthma, respectively and both diseases have shown an intimate connection in their genesis, coexistence and similarities as triggered by the same etiological agents; the same inflammatory cell profile and share therapeutic treatment. This review highlights the concept of CARAS by its phenotype, endotype and biomarker classification.
