In silico and in vitro exploration of a tyrosinase for biocatalytic production of catechols
FEBS Open Bio, EarlyView.Tyrosinase from Ralstonia pseudosolanacearum is a promising biocatalyst for producing valuable catechols from monophenol substrates. This tyrosinase is uniquely suited to this due to its high monophenolase : diphenolase ratio. We combined in silico docking and in vivo kinetic characterisation of this tyrosinase with 11 industrially relevant monophenols,

Biovalentia: Biological Research Journal, 2019 Twelve endophytic fungi were isolated from Jeruju plant. Three of which have the best antioxidant activity, namely Culvularia lunata DJS1, Diaporthe phaseolorum DJS2, and Colletotrichum siamense BJS4. The fungi can produce secondary metabolites that have

Antioxidant Activity of Perphenazine
Acta Poloniae Pharmaceutica - Drug ResearchReactive oxygen species (ROS) play a dual role in the human body; they are essential for normal cellular signaling but, when produced in excess, can disrupt metabolic processes and induce oxidative stress. The body relies on various defense mechanisms to neutralize ROS.

Antioxidant and Photo-antioxidant Activities of Phenylpropanoids
Journal of the Japan Petroleum Institute, 2008 Phenylpropanoids are one of the metabolic products of phenylalanine and tyrosine. The antioxidant and photo- antioxidant activities were studied kinetically and along the metabolic pathway, to investigate the possibility of application to petrochemical products. The metabolites showed only slight photo-antioxidant activities, compared with a commercial

Chronobiology of Cancer: How Aging Fuels Oncogenesis at the Molecular Level
Aging and Cancer, EarlyView.This graphical abstract illustrates the key biological pathways linking aging with cancer development and progression. In the upper left, cumulative exposure to ultraviolet radiation, toxins, and reactive oxygen species (ROS) causes DNA damage and genomic instability, whereas age‐related decline in repair mechanisms, such as ATM/ATR, BER, and NER ...

Aging and Cancer, EarlyView.Cancer treatment is associated with measurable acceleration of biological aging across epigenetic, telomere, senescence, and immune biomarkers. However, biomarker validation and interventional strategies remain limited, especially in hematologic malignancies, underscoring the need for standardized multi‐omic aging assessments and adequately powered ...
