Synthesis and evaluation of nanosized aluminum MOF encapsulating Umbelliferon: assessing antioxidant, anti-inflammatory, and wound healing potential in an earthworm model.

BMC biotechnology 2024

Abstract

Nanoporous aluminum metal-organic framework (Al-MOF) was synthesized via solvothermal methods and employed as a carrier matrix for in vitro drug delivery of Umbelliferon (Um). The encapsulated Um was gradually released over seven days at 37 °C, using simulated body fluid phosphate-buffered saline (PBS) at pH 7.4 as the release medium. The drug release profile suggests the potential of Al-MOF nanoparticles as effective drug delivery carriers. Structural and chemical analyses of Um-loaded Al-MOF nanoparticles (Um-Al MOF) were conducted using Fourier-transform infrared (FTIR) spectroscopy, X-ray diffractometry (XRD), and ultraviolet-visible (UV-Vis) spectroscopy. Thermal gravimetric analysis (TGA) was employed to investigate the thermal stability of the Al-MOF nanoparticles, while Transmission Electron Microscopy (TEM) was utilized to assess their morphological features. Um-Al MOF nanoparticles demonstrated notable antioxidant and anti-inflammatory properties compared to Um and Al-MOF nanoparticles individually. Moreover, they exhibited significant enhancement in wound healing in an earthworm model. These findings underscore the potential of Al-MOF nanoparticles as a promising drug delivery system, necessitating further investigations to explore their clinical applicability.
