dihydroxycinnamic acid/inflammation

BACKGROUND 3,4-dihydroxycinnamic acid and its derivatives exhibit numerous biologic activities. Such activities have not previously been reported for 3,5-dihydroxycinnamic acid derivatives. In this study, ten derivatives of 3,5- dihydroxycinnamic acid were synthesized and their anti-inflammatory

The inhibition of 5-lipoxygenase (5-LO), the key enzyme for the biosynthesis of leukotrienes (LTs), has generated increasing enthusiasm as anti-inflammatory and antitumor strategies in recent years. Based on our previous studies, we synthesized a series of dihydroxycinnamic acid-based analogs that

Caffeic acid (3,4-dihydroxycinnamic acid, CA) has been reported to have anti-inflammatory activity in animal models. However, the mechanisms underlying the anti-inflammatory effects of CA in skin inflammation are only partially understood. The present study was designed to investigate the effects

Superoxide radicals have been implicated in the pathogenesis of aging, cataract, ischemia-reperfusion, cancer and inflammatory diseases. In the present work, we found that deferiprone (L1), an iron-chelating drug, and dietary dihydroxycinnamic acids (catechols) were much more effective at protecting

The aggregation of amyloid-β protein (Aβ) is deemed a vital pathological feature of Alzheimer's disease (AD). Hence, inhibiting Aβ aggregation is noticed as a major tactic for the prevention and therapy of AD. Hydroxycinnamic acid, as a natural phenolic compound is widely present in plant foods and

Traumatic brain injury induces neuron damage in early phase, and astrogliosis and the formation of the glial scar in late phase. Caffeic acid (3, 4-dihydroxycinnamic acid), one of the natural phenolic compounds, exerts neuroprotective effects against ischemic brain injuries with anti-oxidant and

BACKGROUND Reperfusion injury is a phenomenon that occurs when tissues are subjected to ischaemia for a variable period of time, after which they are reperfused. Many factors have been implicated in the cause of reperfusion injury including free radicals and neutrophils. Caffeic acid

Many anticancer drugs that are currently used in cancer treatment are natural products or their analogues by structural modification. Caffeic acid (3, 4-dihydroxycinnamic acid; CA) is classified as hydroxycinnamic acid and has a variety of potential pharmacological effects, including antioxidant,

A series of novel diosgenin (DSG) and tigogenin (TGG) derivatives with diosgenin or tigogenin steroid aglycons linked to levulinic and 3,4-dihydroxycinnamic acids, dipeptides and various amino acids by an ester bond at the C3-oxygen atom of the steroid skeleton has been synthesized. Diosgenyl esters

Role of neuroinflammatory mediators particularly cyclooxygenase (COX), lipoxygenase (LOX), have been well suggested in the pathophysiology of neurodegenerative disorders. Rofecoxib is a selective cyclooxygenase 2 enzymes belongs to non-steroidal anti-inflammatory drug, commonly called as coxibs.

Polyphenols are secondary metabolites of plants and include a variety of chemical structures, from simple molecules such as phenolic acids to condensed tannins and highly polymerized compounds. Caffeic acid (3,4-dihydroxycinnamic acid) is one of the hydroxycinnamate metabolites more widely
