Ayanin has vasorelaxant activity, it also may have the potential for use in treating allergic asthma.The IC(50) value of Ayanin (quercetin-3,7,4'-O-trimethylether) is 2.2microM for inhibiting interleukin (IL)-4 production from purified basophils.

Lipopolysaccharides (LPS), derived from Escherichia coli O55:B5, are essential components of the outer membrane of Gram-negative bacteria. Composed of lipid A, a core oligosaccharide, and an O-specific polysaccharide, LPS exhibits strong immunogenicity. It activates immune cells via the TLR4 receptor, induces chemotactic cell migration and cytokine secretion, and helps maintain the integrity of the bacterial outer membrane, protecting against bile salts and lipid-based antibiotics. LPS is commonly used to establish inflammatory models, including arthritis, chronic obstructive pulmonary disease (COPD), acute respiratory distress syndrome (ARDS), and gastrointestinal disease models.

Bisphenol A is an endogenous metabolic compound of phenols and is widely used in the production of epoxy resins and polycarbonate plastics. It is reproductive, developmental and systemic toxicant and is often classified as an endocrine disruptor. It has been linked to many diseases, including respiratory disease, cardiovascular disease, diabetes, kidney disease, obesity and reproductive disorders.

2,3-Pentanedione is a food additive that also occurs naturally as a fermentation product in beer, wine and yogurt and is released during the roasting of coffee beans. Inhalation of 2,3-Pentanedione is thought to be the cause of severe respiratory disease in humans, including occlusive bronchitis.

Levocarnitine propionate (L-Propionylcarnitine) is a propionyl-coenzyme A (Pro-CoA) derivative with anti-ischemic effects and high affinity for muscle L-carnitine transferase. Levocarnitine propionate enhances substrate oxidation and mitochondrial respiration in the heart of diabetic rats, reduces gastric ulcer area, induces mucosal recovery, and can be used to study acute respiratory distress syndrome and chronic gastric ulcers in Alzheimer's disease.

Lipopolysaccharides from Escherichia coli O111:B4 are key components of the outer membrane of Gram-negative bacteria. As a smooth-type LPS, they consist of lipid A, an R3-type core oligosaccharide, and an O-specific polysaccharide. These LPS molecules exhibit high immunogenicity, can trigger strong immune responses and gastric disorders by activating the TLR-4 receptor on immune cells, and help maintain the structural integrity of the bacterial outer membrane while protecting against bile salts and lipid-based antibiotics. They are widely used to establish inflammation-related disease models, such as chronic obstructive pulmonary disease (COPD) and acute respiratory distress syndrome (ARDS).

Vasicine is oxytocic and abortifacient agents.Vasicine, a potential natural cholinesterase inhibitor, has been in development for treatment of Alzheimer's disease. Vasicine can regulate the inflammatory reaction, have great potentials to develop safe medi

Vasicinone may act as a hepatoprotective agent. (±)-Vasicinone has significant antitussive, expectorant, and bronchodilating activities, which can be used to treat respiratory disease.(S)-Vasicinone exhibits antiproliferative activity against human gastric cancer cells MCG-803.

4-Methoxycinnamaldehyde (p-Methoxycinnamaldehyde) is an active ingredient of Agastache rugosa.4-Methoxycinnamaldehyde has cytoprotective activity against respiratory syncytial virus (RSV) in human laryngeal carcinoma cell lines, and helps to control disease induced by RSV infection, with an IC50 of approximately 0.055 μg/mL. The IC50 was about 0.055 μg/mL.
