Abstract: There is provided acid-resistant capsules, and in particular acid-resistant, vegetarian-based, and/or gelatin-based soft gel capsules and method of manufacturing the soft gel capsule. The soft gel capsule has 30% wt. to 45% wt. water; 15% wt. to 19% wt. glycerol; and a gel mass composition comprising a gelling agent and an alkaline agent. The method of manufacturing the capsule involves: dissolving a gelling polymer into water to form an enteric polymer solution; mixing an acid insoluble polymer with an alkali agent to form a film forming polymer; and adding the film forming polymer to the enteric polymer solution while mixing and heating at 70° C. until a gel mass forms.

Abstract: 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 derivatives possess anti-mycobacterial activity and are particularly useful for the treatment of Mycobacterium tuberculosis infections. In particular, fluorinated analogs of thioacetazone and p-amino-salicylic acid have been synthesized for use as anti-tuberculosis therapeutic agents either alone or in combination with other conventional anti-tuberculosis therapeutic agents.
