The development of responsive MRI contrast agents to detect fluctuations in Zn(II) is a growing area of research. Here we describe a high-spin Fe(III) coordination complex, Fe(ADAPT), as one of the first examples of an Fe(III) MRI probe that is responsive to Zn(II). The six-coordinate Fe(ADAPT) contains a phenolate-appended 1,4,7-triazacyclononane (TACN) ligand framework, with the phenolate groups linked to a Zn(II) binding moiety.

The incorporation of multiple Fe(III) centers bridged by rigid ligands into a coordination cage represents a powerful approach for designing effective MRI contrast agents. In this context, an octahedral coordination cage with six high-spin Fe(III) centers is shown to be water soluble, robust towards dissociation and has effective relaxivity as a MRI probe in solution and in mice.

This study aimed to assess the rates and causes of metformin non-adherence and to investigate knowledge, attitudes, and practices (KAP) on misconceptions of metformin use including the association with socio-demographic variables.
Methods: An observational analytical cross-sectional study was conducted at the diabetes clinic of Karapitiya Teaching Hospital in Galle, Sri Lanka.
