A family of bioactive compounds identified in self-resolving inflammatory exudates is disclosed. The compounds give UV chromophores characteristics of a conjugated triene double bond system coupled to an auxochrome allylic to the triene. Further elucidation of the compounds reveals that they have an oxylipin backbone conjugated to a peptide or amino acid moiety via an auxochrome. In some embodiments the auxochrome is sulfur. However, the auxochrome may be NH, CH2 or O. The compounds have potent bioactivity, in vitro, and, in vivo, including promoting resolution of infection, stimulating macrophage phagocytosis of bacteria; protecting tissues from neutrophil mediated damage, promoting tissue repair and regeneration and preventing or limiting second organ reflow/reperfusion damage.
本研究揭示了在自溶性炎性渗出物中发现的一系列生物活性化合物。这些化合物的紫外发色团具有共轭三烯双键系统的特征,并与三烯的烯丙基辅助色素相耦合。对这些化合物的进一步阐释表明,它们具有通过辅助色素与肽或氨基酸分子共轭的氧化脂素骨架。在某些实施方案中,辅助色素是硫。这些化合物在体外和体内具有强大的生物活性,包括促进感染的解决,刺激巨噬细胞吞噬细菌;保护组织免受中性粒细胞介导的损伤,促进组织修复和再生,防止或限制第二器官回流/再灌注损伤。
