Nitro-Fatty Acids: From Detection and Synthesis to Biological Effects and Therapeutics

The study of nitro-fatty acids represents a captivating intersection of biochemistry and pharmacology, as these bioactive lipids emerge as pivotal players in cellular signaling and therapeutic exploration. Arising from reactions between nitric oxide-derived species and lipid oxidation intermediates, nitroalkenes have been identified as novel anti-inflammatory mediators. Their detection in animal tissues and plants has reinforced the observation that nitroalkenes can be endogenously formed during digestion and inflammatory responses.Due to their unique biochemical characteristics, nitroalkenes undergo Michael addition with biological nucleophiles, leading to the post-translational modification of protein thiols. This action modulates transcriptional regulatory proteins and thereby shapes key signaling networks, endowing nitroalkenes with significant anti-inflammatory potential. Such effects have been consistently demonstrated across diverse animal models of disease, highlighting their translational relevance.This Research Topic aims to elucidate the broad implications of nitro-fatty acids, spanning from their chemical formation and metabolism to their roles in signaling and therapeutic applicability. Central questions include the mechanistic pathways by which nitroalkenes exert their effects and their potential to be developed as innovative clinical interventions. Importantly, ongoing Phase I clinical trials underscore the promise of nitroalkenes, offering critical insights into their practical applications in human health.The scope of this Research Topic traverses the landscape of nitro-fatty acid research, and we invite contributions that address:Biochemical detection and quantification of nitro-fatty acidsAnalysis of nitroalkene formation and metabolismExploration of nitroalkene-mediated signaling pathwaysAssessment of anti-inflammatory properties in various disease modelsEvaluation of clinical applicability and outcomes from ongoing trialsBy integrating diverse perspectives, this collection will advance the understanding of nitro-fatty acids and their therapeutic potential within the scientific community.
