Abstract:
N-(2H,3H,4H-4-oxo-6-R1-2-R2O-benzopyran-3-ylidenmethyl) derivatives and imino derivatives of 3-, 4-, 5-aminosalicylic acids were prepared. It was found that some of the synthesized derivatives of 4-aminosalicylic acid are as effective against typical and atypical strains of mycobacteria as isoniazid (INH). Interesting activity of some derivatives against yeast was also found.
