<p>Halogenated derivatives of two synthetic anti-tuberculosis agents, thioacetazone and p-aminosalicylic acid, have been synthesized. In general, the halogenated compound has the structure of Structure (I), wherein X1 is a halogen and X2 is a second halogen or hydrogen, and Y is sulfur or oxygen;or, has the structure of Structure (IV), wherein X1 is a halogen and X2 is a second halogen or hydrogen. Alternatively, the halogenated compounds may be pharmaceutically acceptable salts of these compounds. These halogenated derivates possess anti-mycobacterial activity and are particularly useful for the treatment of Mycobacterium tuberculosis infections. In particular, fluorinated analogs of thioacetazone and p-aminosalicylic acid have been synthesized for use as anti-tuberculosis therapeutic agents either alone or in combination with other conventional anti-tuberculosis therapeutic agents.</p> |
