Design of Potential Pharmaceutical-Based Metal Complexes Derived from Cromolyn a Mast Cell Stabilizer.

A series of pharmaceutical metal complexes (pMCs) were produced and characterized using the mast cell stabilizer, cromolyn, and bioactive metal ions (Zn, Mg, and Ca). Three novel pMCs, Cromolyn-Zn, Cromolyn-Mg, and Cromolyn-Ca, were formed through reactions under controlled temperature and pH conditions. Additional characterization for these materials was performed employing a number of solid-state characterization techniques, such as thermogravimetric analysis (TGA), powder and single-crystal X-ray diffraction (PXRD and SCXRD), and scanning electron microscopy coupled with energy-dispersive spectroscopy (SEM-EDS).
