RESUMEN
Ethambutoldihydrogenchloride [EMB] with chemical formula C[10]H[24]N[2]O[2].2HCl is ethane-1,2-diamine in which one hydrogen attached to each of the nitrogen is substituted by a 1-hydroxybutan-2-yl group [S,S-configuration]. It is an FDA approved drug and has been used for treatment of tuberculosis since 1960's. Prolong use of EMB has a side effect of visual impairment and in literature it is related with the depletion of Zn metal from the body. As it is a good chelating agent, many metal II complexes have been synthesized with anti-tubercular activity. The purpose of this work was to synthesize metal II complexes of EMB and to evaluate their antioxidant activity along with enzyme inhibition activity [acetylcholine esterase and protease]. The metals used for complex formation were Co, Zn, Fe, Cu and Ni. IR spectral data and physical parameters supported the complex formation. The obtained results showed the synthesized complexes as notable antioxidants and enzyme inhibitors
