Article Synopsis
  • Researchers identified and characterized a new flavonol compound, opuntiol, from cactus pads using chromatography and various spectroscopy methods.* -
  • The structure of opuntiol was determined to be near planar and stabilized by specific hydrogen bonds, as shown through single-crystal X-ray diffraction.* -
  • Opuntiol demonstrated significant anti-proliferative effects on KB cancer cells, inducing ROS generation and apoptosis, with an inhibition concentration (IC) value of 30 µM.*

The principal objective of this study is to determine the resistance of Deinococcus radiodurans to hydrogen peroxide (HO) induced oxidative stress by inhibiting its thioredoxin reductase (TrxR) antioxidant system. Treatment of D. radiodurans with different TrxR inhibitors such as ebselen, epigallocatechin gallate and auranofin displayed this organism sensitivity to HO treatment in a concentration-dependent manner.

Ultraviolet-B radiation (285-320 nm) elicits a number of cellular signaling elements. We investigated the preventive effect of linalool, a natural monoterpene, against UVB-induced oxidative imbalance, activation of mitogen-activated protein kinase (MAPK) and nuclear factor kappa-B (NF-κB) signaling in HDFa cells. We observed that linalool treatment (30 μM) prevented acute UVB-irradiation (20 mJ/cm2) mediated loss of activities of antioxidant enzymes in HDFa cells.
