Antimicrobial and anticancer activities of bisacodyl and it’s deacetylated metabolite DDPM

The antibacterial activity of bisacodyl and its deacetylated metabolite, DDPM was investigated against Gram-positive pathogens including Staphylococcus aureus (ATCC 9144), Micrococcus luteus (LB14110), Salmonella enterica (NCTC 6017) with minimal inhibitory concentration (MIC) ranging from 12.5 to 25 μg/mL, 6.25 to 12.5 μg/mL and 25 to 50 μg/mL respectively. The results of antibacterial activity against Gram-negative foodborne Pseudomonas aeruginosa (ATCC 9027), Escherichia coli (ATCC 8739), show MIC values between 12.5-25 μg/mL and 25-50 μg/mL. The antifungal activity was also evaluated against the opportunistic pathogenic yeast Candida albicans (ATCC 2091) with MIC ranging from 12.5 to 25 μg/mL. Furthermore, the anticancer activity was evaluated against epithelial cervical cancer cell line (ATCC, Manassas,VA, USA). The results obtained indicated that bisacodyl and its deacetylated metabolite, DDPM have a cytotoxic activity at 63.69 μg/mL and 16.7 μg/mL respectively.
