Abstract-2-Nitro-6-[(4-phenyl-benzo[4,5]imidazo[1,2-a]pyrimidin-2-ylim ino)-methyl]-phenol (LH1), a novel Schiff base compound with benzimidazole moiety was successfully synthesized and characterized using UV-VIS light, FTIR, 1 H and 13 C NMR. The compound was screened for its antifungal and bactericidal properties against seven fungal strains and twelve pathogenic bacteria. Disc diffusion method was used for antifungal activity and broth microdilution technique was used to determine the minimum inhibitory concentration (MIC). The compound showed strong inhibitory growth property against all fungal strains than reference material amphotericin B. Fusarium verticillioides was the most sensitive fungus with 18 mm diameter of the inhibition zone. Gram-positive bacteria were more sensitive to LH1 compared to Gram-negative. LH1 showed more potent activity inducing bacteria cell death than the controls particularly with Bacillus cereus (MIC 7.8 µg/mL) against streptomycin and nalidixic acid (MIC 512 µg/mL). We conclude that LH1 has a low tolerance to these microbes, and promise to be a better remedy against their metabolic expressions
