RESUMO

The recent development and implementation of copper-based metal-organic frameworks in biological applications are reviewed. The advantages of the presence of copper in MOFs for relevant applications such as drug delivery, cancer treatment, sensing, and antimicrobial are highlighted. Advanced composites such as MOF-polymers are playing critical roles in developing materials for specific applications.

RESUMO

Linezolid (LNZ) is a new-generation synthetic molecule for the antibacterial treatment of severe infections, particularly in infective cases where the bacterial resistance to first-choice drugs is caused by Gram-positive pathogens. In this context, since 2009, some strains resistant to LNZ in patients with long-term treatments have been reported. Therefore, there is a need to use not only new drug molecules with antibacterial activities in the dosage form but also a different approach to pharmacotherapeutic strategies for skin infections, which lead to a reduction in the concentration of biocides. This work explores LNZ hosted at two isostructural MOFs, MOF-74(Zn) and MOF-74(Cu), as promising antimicrobial systems for gradual biocide release within 6 h. These systems reach a lower minimum inhibitory concentration (MIC) in comparison to free LNZ. Even a decreased MIC value is also observed, which is an encouraging result regarding the efficiency of the systems to control concentration-dependent antimicrobial resistance.

RESUMO

The Sc(III) MOF-type MFM-300(Sc) is demonstrated in this study to be stable under physiological conditions (PBS), biocompatible (to human skin cells), and an efficient drug carrier for the long-term controlled release (through human skin) of antioxidant ferulate. MFM-300(Sc) also preserves the antioxidant pharmacological effects of ferulate while enhancing the bio-preservation of dermal skin fibroblasts, during the delivery process. These discoveries pave the way toward the extended use of Sc(III)-based MOFs as drug delivery systems (DDSs).
