一般說明
依克多因(Ectoine)是一种天然的环状四氢嘧啶,它是一种可以与水结合的低分子量有机渗透剂。它是一类小分子伴侣(small molecule chaperone,SMC)的一部分。
生化/生理作用
依克多因是多种微生物中的渗透保护剂,包括异养、嗜盐菌和非嗜盐菌,如链霉菌和大肠杆菌。这种相容性溶质对大肠杆菌在干燥和储存过程中也有保护作用。依克多因与蛋白质和脂质双层的稳定有关。它还调节膨压的保持并减轻干燥胁迫。它可以用于治疗炎症性疾病,例如过敏性鼻炎、特应性皮炎和慢性阻塞性肺疾病。依克多因可以在体外引起DNA结构变化,并保护DNA免受电离辐射(IR)的伤害。它可以防止胰岛素淀粉样蛋白在体外形成。
