Ethambutol is a primary antibiotic used to treat tuberculosis (TB), the most deadly infectious disease
worldwide. However, ethambutol has some serious side-effects, including liver damage and inflammation of the optic
nerves. Conversion of ethambutol to an ester-protected prodrug could alleviate some of these side-effects and could
increase the specificity of the drug for M. tuberculosis. Ten ester-protected ethambutol derivatives were synthesized to
determine the toxicity, chemical properties, and biological functions of each derivative. The ability of each ester-protected derivative to act as prodrug was analyzed. The results of this project provide new insight on how the
chemical and biological properties of antibiotics affect their toxicity against TB.
