Potent inhibition of human cytochrome P450 by cannabidiol

In this study, we examined the inhibitory effects of Δ9-tetrahydrocannabinol (Δ9-THC), cannabidiol (CBD), and cannabinol (CBN), the three major cannabinoids, on the activity of human cytochrome P450 (CYP) 3A enzymes. Furthermore, we investigated the kinetics and structural requirement for the inhibitory effect of CBD on the CYP3A activity. Main methods: Diltiazem N-demethylase activity of recombinant […]

Physalin F Induces Cell Apoptosis in Human Renal

Background: The aim of this study was to determine the molecular mechanisms of physalin F, an effective purified extract of Physalis angulata L. (Solanacae), in renal carcinoma A498 cells. Methodology/Principal Findings: Physalin F was observed to significantly induce cytotoxicity of three human renal carcinoma A498, ACHN, and UO-31 cells in a concentration-dependent manner; this was […]

Curcumin: A novel approach to target and treat multidrug-resistant cancers

Curcumin is a functional food, which provides a wide range of health benefits including anti-cancer activity and considered as a suitable alternative for chemotherapeutic agents. However, cancer cells exhibit resistance to most chemotherapeutic agents including curcumin due to overexpression of adenosine triphosphate (ATP)-binding cassette transporter proteins in the cancer cell membrane, which decrease the intracellular […]
