Aging is a degenerative process characterized by progressive deterioration of cellular components, ultimately resulting in mortality, in which massive accumulation of reactive oxygen species (ROS) and advanced glycation end products (AGEs) are implicated as crucial factors. At the same time, natural products are rich sources from which to isolate and characterize potential anti-aging compounds. The current study was designed to extract compounds from the marine bacterium Pseudomonas sp. and investigate their in vitro antioxidant and anti-glycation activities, as well as their in vivo effects on aging in the model organism Schizosaccharomyces pombe. In vitro assays showed that a Pseudomonas sp. PTR-08 extract exhibited the best antioxidant and anti-glycation activities. Further, direct administration of the extract significantly increased yeast longevity, accompanied by induction of the yeast oxidative stress response. Molecular analyses indicated that selected extract dramatically up-regulated the expression of pap1 + , which encodes the transcriptional factor Pap1 and ctt1 + , which encodes catalase, following H 2 O 2  treatment. In line with these results, catalase activity significantly increased, leading to a decrease in intracellular ROS. In addition, this extract may delay the G1 phase of the yeast cell cycle, leading to an extended lifespan. Moreover, our findings indicated that the extract contains pyrrolo[1,2-a]pyrazine-1,4-dione, hexahydro-, which substantially promotes anti-aging activity in yeast. However, further research must be conducted to better understand the role of this compound in our system.
