allergic asthma

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.

1. Kuwanon G (Moracenin B) as dual inhibitors of PTP1B and α-glucosidase enzymes, as well as insulin sensitizers, it may potentially be utilized as an effective treatment for Type II diabetes mellitus. 2. Kuwanon G has anti-inflammatory activity, it can attenuate atherosclerosis through inhibiting foam cell formation and inflammatory response. 3. Kuwanon G is a potent inhibitor of Mycobacterium tuberculosis protein tyrosine phosphatase B. 4. Kuwanon G shows acetylcholinesterase (AChE) and butyrylcholinesterase(BChE) inhibitory activities, it may be a promising candidate for preventive and therapeutic agents for Alzheimer's disease. 5. Kuwanon G prevents the pathological progression of allergic asthma through the inhibition of lung destruction by inflammation and immune stimulation. 6. Kuwanon G has antibacterial activity against oral pathogens. 7. Kuwanon G is a specific antagonist for the GRP-preferring receptor and can be useful for studying the physiological and pathological role of GRP.

Gymnoside I (compound 1), a glycosidoxybenzyl 2-isobutylmalic acid, exhibits antiallergic properties, particularly in the passive cutaneous allergic reaction (PCA) test in mice. It holds potential for research applications in the treatment of asthma, neurasthenia, and chronic hepatitis [1].

Sappanone A is a high isoflavanone that exhibits anti-inflammatory effects by modulating Nrf2.Sappanone A attenuates allergic airway inflammation in ovalbumin-induced asthma.

Sulfuretin is a potent anti-oxidant, has protective effect against t-BHP-induced oxidative damage in human liver-derived HepG2 cells is attributable to its ability to scavenge ROS and up-regulate the activity of HO-1 through the Nrf2/ARE and JNK/ERK signa

Bakkenolide B is a natural product discovered in Petasites japonicas that suppresses allergic and inflammatory responses. It inhibits the gene induction of inducible nitric oxide synthase and cyclooxygenase-2 in mouse peritoneal macrophages and can be used for asthma research.
