biflavone/inflammation

Biflavonoid is one of unique classes of naturally-occurring bioflavonoids. Certain biflavonoids including amentoflavone were previously reported to have inhibitory effect on the group II phospholipase A2 activity. Amentoflavone was also found to inhibit cyclooxygenase from guinea-pig epidermis

Ginkgetin, a biflavone from Ginkgo biloba leaves, was previously reported to be a phospholipase A(2) inhibitor and this compound showed the potent antiarthritic activity in rat adjuvant-induced arthritis as well as analgesic activity. This investigation was carried out to find effects on

Ginkgetin, a biflavone isolated from Ginkgo biloba leaves, was previously reported as an inhibitor of group II phospholipase A2. In this study, ginkgetin was evaluated for in vivo antiarthritic and analgesic activities. Ginkgetin (10-20 mg/kg/day) strongly reduced arthritic inflammation in an animal

In order to establish anti-inflammatory potential of biflavonoids, 17 biflavone derivatives having a 6-O-7'' linkage were synthesized and their effects on cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS) were evaluated. The basic molecule (6-O-7'' biflavone) potently inhibited

Ginkgo biloba has long been used in ancient China for the treatment of cough, asthma, and other lung diseases. However, the active constituents in G. biloba for pulmonary disease treatment remain unclear. The objective of this study was to evaluate the anti-inflammatory active constituents in G.

Natural products, being richly endowed with curative powers, have become spotlight for biomedical and pharmaceutical research to develop novel therapeutics during recent years. Ginkgetin, a natural non-toxic biflavone, has been shown to exhibit anti-cancer, anti-inflammatory, anti-microbial,

Previously, a synthetic biflavone having a C-C (6-6") linkage ([6,6"]biflavone, BF6-6) was shown to possess considerable anti-inflammatory activity. The present investigation was conducted to develop more active anti-inflammatory biflavonoids having unique mechanisms of action based on the BF6-6

Ginkgetin, a biflavone from Ginkgo biloba leaves, was previously reported to be a phospholipase A2 inhibitor and this compound showed the potent antiarthritic activity in rat adjuvant-induced arthritis as well as analgesic activity. This investigation was carried out to find effects on

BACKGROUND Biflavones of Hypericum perforatum L. are bioactive compounds used in the treatment of inflammation and depression. Determination of amentoflavone and biapigenin from blood is challenging owing to their similar structures and low concentrations. OBJECTIVE To develop a rapid, sensitive and

Dietes bicolor (Iridaceae) is an ornamental plant used by African local healers to treat diarrhea and dysentery. A new dihydroflavonol, (2R,3R)-3,5,7-trihydroxy-8-methoxyflavanone (1); two known dihydroflavonols, trans-3-hydroxy-5-methoxy-6,7-methylenedioxyflavanone (2) and

Amentoflavone is a natural biflavone compound with many biological properties, including anti-inflammatory, antioxidative, and neuroprotective effects. We presumed that amentoflavone exerts a neuroprotective effect in epilepsy models. Prior to model establishment, mice were intragastrically

Amentoflavone, which is a biflavone derived from various plants, has been known to possess various biological activities including anti-tumor and anti-inflammatory activity. In the previous study, we reported antifungal effect of amentoflavone isolated from an ethyl acetate extract of Selaginella

The extracellular accumulation of amyloid beta protein (Aβ), reactive gliosis and cerebral amyloid angiopathy (CAA) play critical roles in the pathogenesis of Alzheimer's disease (AD). Ginkgetin, a biflavone isolated from Ginkgo biloba leaves, was previously reported to exhibit strong

Standardized extracts of Ginkgo biloba leaves are mainly used in the treatment of peripheral and celebral circulation disorders, and also as a remedy against asthma, coughs, bladder inflammation, blenorrhagia and alcohol abuse. The leaf extracts contain biflavones, flavonol glycosides and terpene

Hinokiflavone (HF), belonging to biflavonoids, possesses excellent pharmacological activities, including anti-inflammatory, antioxidant and antitumor activity. Nevertheless, its metabolism in vivo (rats) and in vitro (rat liver microsomes and intestinal flora) is presently not characterized. In this
