Abstract
Oxidative stress is a natural physiological process where the levels of oxidants, such as reactive oxygen species (ROS) and nitrogen (RNS), exceed the strategy of antioxidant defenses, culminating in the interruption of redox signaling and control. Oxidative stress is associated with multiple pathologies, including premature aging, neurodegenerative diseases, obesity, diabetes, atherosclerosis, and arthritis. It is not yet clear whether oxidative stress is the cause or consequence of these diseases; however, it has been shown that using compounds with antioxidant properties, particularly compounds of natural origin, could prevent or slow down the progress of different pathologies. Within this context, the Caenorhabditis elegans (C. elegans) model has served to study the effect of different metabolites and natural compounds, which has helped to decipher molecular targets and the effect of these compounds on premature aging and some diseases such as neurodegenerative diseases and dyslipidemia. This article lists the studies carried out on C. elegans in which metabolites and natural extracts have been tested against oxidative stress and the pathologies associated with providing an overview of the discoveries in the redox area made with this nematode.

Abstract
Achyrocline flaccida aqueous extract was obtained by macerating wildflowers. The phytochemical profile present in the A. flaccida aqueous extract was elucidated by HPLC-ESI-MS/MS. Toxicity was evaluated in vitro by comet assay in peripheral blood mononuclear cells (PBMCs) and in vivo using Caenorhabditis elegans as a model. The antioxidant activity was also evaluated, and antimycobacterial activity was assessed by the broth microdilution method. The compounds present in the aqueous extract mainly belonged to the flavonoid class (89%). The concentrations that showed protective effects in C. elegans against oxidative stress and antimycobacterial activity had no toxic effects. The antimycobacterial activity test demonstrated that the concentration of 1,560 µg mL-1 inhibited the growth and eradication of the mycobacterial tested strains. Based on our findings, the A. flaccida aqueous extract presents a viable potential in developing new phytotherapeutic drugs against mycobacteria of clinical relevance.
