WebThis species belongs to the Oecophoridae, and is a specialist feeder on three genera of furanocoumarin-containing Apiaceae. It is highly tolerant to these compounds, and metabolizes them not just by opening the furan ring; in the case of sphondin, it is also capable of O-demethylation ( Nitao et al., 2003 ). WebAbstract. A series of novel biphenyl-furocoumarin derivatives were synthesized based on the nuclear structure of imperatorin and identified by IR, 1 H NMR, 13 C NMR and MS, and evaluated for their ability to relax vessel on isolated rat mesenteric artery, basilar artery and renal artery, respectively. The majority of compounds demonstrated potent …
