Cyclodextrin Metal-Organic Framework as a Broad-Spectrum Potential Delivery Vehicle for the Gasotransmitters.

Area of Science:

• Biomedical Engineering
• Materials Science
• Nanotechnology

Background:

• Gasotransmitters play crucial roles in physiological and pathophysiological processes.
• Challenges in storage and controlled delivery of gasotransmitters impede therapeutic development.
• A facile and scalable method for delivering multiple gasotransmitters is needed.

Purpose of the Study:

• To develop a broad-spectrum delivery vehicle for multiple gasotransmitters.
• To investigate the controlled release and biological relevance of delivered gasotransmitters.
• To assess the biocompatibility and potential of the delivery system for therapeutic applications.

Main Methods:

• Ultrasonic-assisted preparation of gamma-cyclodextrin metal-organic framework (γ-CD-MOF).
• Loading and controlled release of gasotransmitters (SO2, NO, H2S) from γ-CD-MOF.
• Modification of γ-CD-MOF with Pluronics to tune gasotransmitter release rates.
• Evaluation of biological effects, including DNA cleavage and anti-inflammatory activity.
• Assessment of γ-CD-MOF biocompatibility and particle size.

Main Results:

• γ-CD-MOF successfully delivered multiple gasotransmitters (SO2, NO, H2S).
• Gasotransmitter release rates were tunable by modifying γ-CD-MOF with Pluronics.
• Delivered gasotransmitters demonstrated biological relevance through DNA cleavage and anti-inflammatory effects.
• γ-CD-MOF exhibited good biocompatibility with a particle size of 180 nm.

Conclusions:

• γ-CD-MOF serves as an effective broad-spectrum delivery vehicle for gasotransmitters.
• This system offers tunable release and demonstrates biological efficacy.
• γ-CD-MOF is a promising tool for studying gasotransmitter co-delivery and cooperative therapy.
