The aim of our current research was to synthesize some transition metal complexes of Naproxen, determine their physical properties, and examine their relative stability under various conditions. Characterizations of these complexes were done by 1H-NMR, Differential Scanning Calorimetry (DSC), FT-IR, HPLC, and scanning electron microscope (SEM). Complexes were subjected to acidic, basic, and aqueous hydrolysis as well as oxidation, reduction, and thermal degradation. Also the reversed phase high-performance liquid chromatography (RP-HPLC) method of Naproxen outlined in USP was verified for the Naproxen-metal complexes, with respect to accuracy, precision, solution stability, robustness, and system suitability. The melting points of the complexes were higher than that of the parent drug molecule suggesting their thermal stability. In forced degradation study, complexes were found more stable than the Naproxen itself in all conditions: acidic, basic, oxidation, and reduction media. All the HPLC verification parameters were found within the acceptable value. Therefore, it can be concluded from the study that the metal complexes of Naproxen can be more stable drug entity and offer better efficacy and longer shelf life than the parent Naproxen.

One pot Mannich reaction involving three components (4-fluorobenzaldehyde, aniline, cyclopentanone) was performed using ethanol as a solvent. The resulting Mannich base (FPC) was isolated and further reacted with chloride salts of Cu(II), Ni(II), Co(II), Fe(II) and Zn(II) ions to afford respective metal complexes. The structure of synthesized ligand and transition metal complexes were elucidated on the basis of IR, 1H NMR, 13C NMR, mass spectroscopy and elemental analysis. The geometries of the resulting complexes were proposed on the basis of electronic spectroscopic data and magnetic moment. The anti-enzymatic activity of the ligand and its metal complexes were carried out against urease. FPC shows potent antiurease activity with IC50 value (0.83� 0.002 �M) which is greater than standard. The Cu-complex shows excellent inhibitory action with IC50 value (16.87� 0.03 �M) while other complexes i.e Co-complex (35.59� 0.04 �M) and Ni-complex (49.93� 0.01 �M) exhibit good to moderate IC50 values as compared with control thiourea (IC50 value, 21.25� 0.15 �M). Molecular docking studies were also done on the antiurease activities of FPC and its complexes.
