A new series of 1H-indole-2-carboxamide derivatives has been prepared by simple procedures in good yields, followed by complete characterization using nuclear magnetic resonance, infrared spectroscopy, high resolution mass spectrometry and elemental analysis techniques. The prepared compounds have been tested as potential antifungal and anti-bacterial (Grampositive and Gram-negative) agents. The antifungal and antibacterial results indicated that carboxylic acid compounds exhibited a weak bioactivity; even with replacement of carboxylic acid group with ester, no significant difference in activities was observed relative to standard commercial drugs.
