Edwardsiella tarda (E. tarda) is a gram-negative bacterium, which causes Edwardsiellosis in aquaculture. Previous studies indicate that E. tarda NanA sialidase plays crucial roles in infection through the desialylation of glycoproteins in fish cells. On the other hand, 2-deoxy-2,3-dehydro-N-acetylneuraminic acid, classic sialidase inhibitor, negatively regulates E. tarda infection of goldfish scale GAKS cells. Here, to development the suppression model of E. tarda infection for aquaculture application, the possibility of NanA inhibitory activities in citrus phytochemicals was evaluated as citrus extracts have widely been used as a supplement in fish diets for the improvement of meat quality...

BACKGROUND: The re-emerging, Aedes spp. transmitted Chikungunya virus (CHIKV) has recently caused large outbreaks in a wide geographical distribution of the world including countries in Europe and America. Though fatalities associated with this self-remitting disease were rarely reported, quality of patients' lives have been severely diminished by polyarthralgia recurrence. Neither effective antiviral treatment nor vaccines are available for CHIKV. Our previous in vitro screening showed that hesperetin, a bioflavonoid exhibits inhibitory effect on the virus intracellular replication...

The present study was designed to investigate the neuroprotective effect of hesperetin (Hp) against cadmium (Cd)-induced neurotoxicity in rats. Cadmium (3 mg/kg body weight (b.w.), subcutaneous) administration for 3 weeks demonstrated neurotoxicity in rats by the decreased activity of acetylcholinesterase in the brain. The oxidative stress markers (thiobarbituric acid reactive substances and protein carbonyls) were significantly increased with decreased enzymatic (superoxide dismutase, catalase, glutathione peroxidase, glutathione S-transferase) and non-enzymatic antioxidants (reduced glutathione, total sulphydryl groups and vitamin C)...

Metal chelates strongly influence the nature and magnitude of pharmacological activities in flavonoids. In recent years, studies have shown that a promising class of flavanone-metal ion complexes can act as selective cholinesterase inhibitors (ChEIs), which has led our group to synthesize a new series of flavanone derivatives (hesperidin, hesperetin, naringin, and naringenin) complexed to either copper (II) or zinc (II) and to evaluate their potential use as selective ChEIs. Most of the synthesized complexes exhibited greater inhibitory activity against acetylcholinesterase (AChE) than against butyrylcholinesterase (BChE)...
