title: In vitro tuberculostatic activities of some 2-benzylbenzimidazole and 2-phenoxymethylbenzimidazole derivatives.
abstract: Some 2-benzylbenzimidazole and 2-phenoxymethylbenzimidazole derivatives were synthesized and tested for in vitro tuberculostatic activity against Mycobacterium tuberculosis H 37 Rv. and human type wild strain (protocol n degrees.4186). The synthesized compounds have one of the CH3, Cl, NO2 or OCH3 groups at position 5 and 4' and are prepared by heating appropriate o-phenylenediamines with the carboxylic acids in the presence of 4.5N HCl. The experiments indicate that 2-phenoxymethylbenzimidazoles were more active than the corresponding 2-benzylbenzimidazoles. The most active compound was 5-chloro-2-phenoxymethylbenzimidazole (IIc) (MIC: 125 micrograms/ml).
