Biodegradable therapeutic MOFs for the delivery of bioactive molecules.

A new metal organic framework (MOF) built up from non-toxic iron and the therapeutically active linker nicotinic acid, with pellagra-curative, vasodilating, and antilipemic properties, has been isolated and characterised via single crystal methods. The release of the therapeutic agent, which is a constituent of the framework, is achieved through the degradation of the hybrid phase, under simulated physiological conditions, allowing for the delivery of the bioactive molecule.
