Composés polycycliques

Nodakenin, a coumarin isolated from the roots of Angelica biserrata (Shan et Yuan) Yuan etShan, possesses neuroprotective, antiaggregatory, antibacterial, and memory

Columbianetin acetate can be absorbed in whole intestinal sections and colon is the best absorption region of whole rat intestines.The increase of columbianetin acetate concentration has no effect on absorption kinetics,the absorption of columbianetin acetate is a passive diffusion process, not pH-dependent.

Isofraxidin-7-O-glucoside(Calycanthoside ) has the anti-inflammatory effect, it has inhibitory activity on NO production.It also shows antibacterial activity.

Imperatorin, a biologically active furanocoumarin from the roots of Angelica dahurica (Umbelliferae), can induce apoptosis in human promyelocytic leukaemia, HL-60 cells,

Umbelliferone (UMB), a natural antioxidant, is benzopyrone in nature, and it is present in the fruits of golden apple and bitter orange, UMB has a protective effect on membrane fatty acid composition of liver and kidney as supported by antioxidant and antihyperlipidemic effects of UMB reported earlier as evidenced by improved histopathological changes, hepatic and nephritic markers, indicating recovery from the risk of diabetic complications; UMB has antihyperglycemic effect, UMB at 30 mg/kg of body weight possesses a promising antihyperglycemic effect that is comparable with glibenclamide.[1,2]

Angelicin is a furocoumarin found in Psoralea corylifolia L. fruit, can block the phosphorylation of IκBα, NFκBp65, p38 MAPK, and JNK in lipopolysaccharide-induced acute lung injury model, suggests that angelicin was potentially advantageous to prevent inflammatory diseases by inhibiting NF-κB and MAPK pathways, it might be a potential new agent for prevention of inflammatory reactions and diseases in the clinic.

Isoimperatorin is a medicinal herbal product that is isolated from the dried roots of Angelicae dahuricae ,can inhibit the cyclooxygenase-2 (COX-2) and COX-1-dependent phases of prostaglandin D 2 (PGD 2 ) generation in bone marrow-derived mast cells (BMMC) in a concentration-dependent manner, with IC 50 values of 10.7 μM and 24 μM, respectively; it may provide the basis for novel anti-inflammatory drugs.

Heraclenin has anticoagulant, and anti-inflammatory activities, it also has mutagenicity in Chlamydomonas reinhardii. Heraclenin can induce apoptosis in Jurkat leukemia cells, it has a strong clastogenic effect . (+)-Heraclenin displays significant levels of antiplasmodial and moderate levels of antimicrobial activities.

Oxypeucedanin is a major coumarin aglycone that can be extracted from Ostericum koreanum, coumarin aglycones have demonstrated various pharmacological effects, including anti-proliferation, anti-inflammation, and anti-pain; based on transcriptional alteration and complicated modulation of MAPK signaling, might be underlying mechanisms responsible for the various pharmacological effects of oxypeucedanin.

Oxypeucedanin hydrate is an antimutagenic agent, it has antioxidant activity, and exhibits carbohydrate metabolizing enzymes inhibitory effect.
