Preparation, physicochemical characterization, and antioxidant effects of quercetin nanoparticles.
The antioxidant activity of the quercetin-loaded nanoparticles developed by a nanoprecipitation technique was more effective than pure QU on DPPH scavenging, anti-superoxide formation, superoxide anion scaventing, and anti-lipid peroxidation. Expand
Antiviral activities of extracts and selected pure constituents of Ocimum basilicum
1. Ocimum basilicum (OB), also known as sweet basil, is a well known medicinal herb in traditional Chinese medicine preparations. In the present study, extracts and purified components of OB wereExpand
Cytotoxicity and anti-hepatitis B virus activities of saikosaponins from Bupleurum species.
It is concluded that saikosaponin c exhibits anti-HBV activity and saikOSaponin d possesses potent cytotoxicity against human hepatocellular carcinoma cells. Expand
Anti-proliferative effect of apigenin and its apoptotic induction in human Hep G2 cells.
The present study concludes that the anti-hepatoma activity of apigenin is as effective as 5-FU and its apoptotic mechanism might be mediated through the p53-dependent pathway and the induction of p21 expression. Expand
Antioxidant activity of Cinnamomum cassia
EECC revealed the strongest antioxidant activity followed by α‐tocopherol and HWECC, and could be used as a good source of antioxidant in the dietary supplement. Expand
Putranjivain A from Euphorbia jolkini inhibits both virus entry and late stage replication of herpes simplex virus type 2 in vitro.
Putranjivain A possesses antiviral activity, inhibiting viral attachment and penetration, and also interfering with the late stage of viral replication. Expand
Resveratrol- induced apoptosis is mediated by p53-dependent pathway in Hep G2 cells.
It was demonstrated that the resveratrol effectively inhibited cell growth and induced programmed cell death in Hepatoma cells on a molecular basis and implied that resver atrol might also be a new potent chemopreventive drug candidate for liver cancer. Expand
Plumbagin (5-Hydroxy-2-methyl-1,4-naphthoquinone) Induces Apoptosis and Cell Cycle Arrest in A549 Cells through p53 Accumulation via c-Jun NH2-Terminal Kinase-Mediated Phosphorylation at Serine 15 in
A critical role for JNK and p53 is suggested in plumbagin-induced G2/M arrest and apoptosis of human nonsmall cell lung cancer cells. Expand
Asiatic Acid, a Triterpene, Induces Apoptosis and Cell Cycle Arrest through Activation of Extracellular Signal-Regulated Kinase and p38 Mitogen-Activated Protein Kinase Pathways in Human Breast
A critical role for ERK1/2 and p38 but not JNK, p53, and Fas/Fas ligand in asiatic acid-induced S-G2/M arrest and apoptosis of human breast cancer cells is implied. Expand
Antioxidant and free radical scavenging activities of Terminalia chebula.
All tested extracts and pure compounds of T. chebula exhibited antioxidant activity at different magnitudes of potency, and the antioxidant activity of each pure compound was derived from different pathways and was suggested to be specific. Expand
