Natural products from food and plant sources have been used for medicinal usage for ages. Also, natural products with therapeutic significance are compounds derived from animals, plants, or any microorganism. In this study, chrysin, carvacrol, hesperidin, zingerone, and naringin as natural phenols showed excellent inhibitory effects against human (h) carbonic anhydrase (CA) isoforms I and II (hCA I and II), α-glucosidase (α-Gly), acetylcholinesterase (AChE), and butyrylcholinesterase (BChE). These phenolic compounds were tested for the inhibition of α-glycosidase, hCA I, hCA II, AChE, and BChE enzymes and demonstrated efficient inhibition profiles with Ki values in the range of 3...

Phytochemicals derived from natural plants have been used commonly for the prevention and/or treatment of different diseases due to the belief of their safety. Many plant species synthesize toxic chemicals. New natural chemicals are being discovered but their toxic effects are unknown. Phytochemicals have been regarded as possible antioxidants. But on the other hand it is suggested that various phenolic antioxidants can display pro-oxidant properties at high doses. In this review, the role of some phytochemicals (epigallocathecin gallate, carvacrol, galangin, limonene, lycopene, naringin, puerarin, terpinene, thymol and ursolic acid) on the prevention of DNA damage will be discussed...

Neutrophil is a significant contributor to ischemia reperfusion (IR) induced liver tissue damage. However, the underlying mechanisms of IR induced innate immune activation and liver damage is not quite clear. Our study sheds light on the role of chronic oxidative stress end products in worsening the IR inflammatory process by neutrophil recruitment and activation following liver surgery. We employed specific inhibitors for molecular targets - NOX2 (NADPH oxidase 2) and P38 MAPK (Mitogen activated protein kinase) signal to counteract neutrophil activation and neutrophil extracellular trap (NET) release induced liver damage in IR injury...

Minimal hepatic encephalopathy (MHE) is induced by elevated intracranial dopamine (DA). The relationship of the Shh pathway with memory loss in MHE, however, is elusive. In the current study, rats with MHE induced with DA displayed downregulation of the Shh pathway. Additionally, injection of Shh into MHE/DA-treated rats reversed downregulation of BDNF/NT3, whereas administration of cyclopamine (Cyc) enhanced the inhibition of expression of BDNF/NT3. Furthermore, naringin (Nrg) substantially prevented cognitive impairment in MHE/DA-treated rats and upregulated the Shh pathway, paralleling the elevated expression of BDNF/NT3...

Human immunodeficiency virus type-1 (HIV-1) envelope glycoprotein 120 has been shown to activate microglia, causing release of inflammatory and toxic factors. The P2X7 receptor, primarily expressed on microglia, is closely associated with inflammation. Naringin, a plant bioflavonoid, has anti-inflammatory and anti-oxidative properties. We hypothesized that P2X7 receptor mediated gp120-induced injury in primary cultured microglia, and that naringin would have a protective effect. We showed that HIV-1 gp120 peptide (V3 loop, fragment 308-331) appeared to induce apoptosis of primary cultured microglia...
