Background: Purine compounds are special types of alkaloids. Caffeine and aminophylline are considered the most important members of purines due to their wide use in therapeutics. Aims: To detect any potential antibacterial effects on pathogenic bacteria of the widely prescribed members of purines caffeine and aminophylline. Materials and Methods: Two species of gram-positive bacteria and five species of gram-negative bacteria were exposed to these purine agents. Antibacterial effects of the tested purines were determined using the spectrophotometer method to assess the minimum inhibition concentrations (MIC). Results: Among the strains of bacteria tested, Bacillus subtilis showed the most susceptibility to purine agents. Staphylococcus aureus and Bacillus subtilis were found to be more susceptible to caffeine than the other strains. Aminophylline showed inhibitory action on many isolates, especially at the concentration of 10mg/ml. Paracoccus yeei demonstrated resistance to all tested purine compounds up to a concentration of 10.5mg/ml. Conclusions: Caffeine and aminophylline had the ability to inhibit many strains of pathogenic bacteria.
