The important role of gasotransmitters in physiology and pathophysiology suggest employing gasotransmitters for biomedical treatment. Unfortunately, the difficulty in storage and controlled delivery of these gaseous molecules hindered the development of effective gasotransmitters-based therapies. The design of a safe, facile, and wide-scale method to delivery multiple gasotransmitters is a great challenge. Herein, we use an ultrasonic assisted preparation γ-cyclodextrin metal organic framework (γ-CD-MOF) as a broad-spectrum delivery vehicle for various gasotransmitters, such as SO, NO, and HS. The release rate of gasotransmitters could be tuned by modifying the γ-CD-MOF with different Pluronics. The biological relevance of the exogenous gasotransmitters produced by this method is evidenced by the DNA cleavage ability and the anti-inflammatory effects. Furthermore, the γ-CD-MOF composed of food-grade γ-CD and nontoxic metal salts shows good biocompatibility and particle size (180 nm). Therefore, γ-CD-MOF is expected to be an excellent tool for the study of co-delivery and cooperative therapy of gasotransmitters.
气体信号分子在生理和病理生理学中的重要作用表明,可以将其用于生物医学治疗。然而,这些气态分子在储存和控制释放方面存在困难,这阻碍了基于气体信号分子的治疗方法的发展。设计一种安全、简便且可广泛应用的方法来输送多种气体信号分子是一个巨大的挑战。在此,我们使用超声辅助制备的γ-环糊精金属有机骨架(γ-CD-MOF)作为各种气体信号分子(如 SO、NO 和 HS)的广谱输送载体。通过用不同的 Pluronic 对 γ-CD-MOF 进行修饰,可以调节气体信号分子的释放速率。该方法产生的外源性气体信号分子的生物学相关性通过 DNA 切割能力和抗炎作用得到证实。此外,由食品级γ-CD 和无毒金属盐组成的γ-CD-MOF 具有良好的生物相容性和粒径(180nm)。因此,γ-CD-MOF 有望成为气体信号分子共递药和协同治疗研究的优秀工具。
