| | AYANIN Usage And Synthesis |
| Uses | Ayanin is a bioflavonoid isolated from Croton schiedeanus Schlecht. Ayanin is a non-selective phosphodiesterase inhibitor. | | Definition | ChEBI: 3',5-dihydroxy-3,4',7-trimethoxyflavone is a trimethoxyflavone that is quercetin in which the hydroxy groups at positions 3, 4' and 7 have been replaced by methoxy groups. It has a role as a plant metabolite. It is a dihydroxyflavone and a trimethoxyflavone. It is functionally related to a quercetin. It is a conjugate acid of a 3',5-dihydroxy-3,4',7-trimethoxyflavone(1-). | | Biological Activity | Ayanin is a biologically active flavonoid isolated from Croton schiedeanus Schlecht. Ayanin is a non-selective phosphodiesterase (phosphodiesterase1-4) inhibitor, which can be used in the study of respiratory diseases, such as allergic asthma. | | in vitro | Ayanin inhibits interleukin (IL)-4 production from purified basophils with an IC 50 value of 2.2 μM. | | target | |
