Abstract: The present invention relates to the field of therapeutics and, more in particular, to pharmaceutical compositions for the prevention and/or treatment of bacterial infections and antibacterial-induced dysfunctions. The compositions of the present invention demonstrate high species-specificity in inhibiting the growth of a small number of bacterial species, and most importantly are effective also against multi drug resistant (MDR) clinical isolate species. Interestingly, one of those combinations pairs a non-antibiotic drug, vanillin, with an antibiotic drug, spectinomycin, to demonstrate a surprisingly strong inhibitory effect on the growth of clinically relevant Gram-negative pathogenic and multi-drug resistant E. coli isolates. A second set of compounds combines the polymyxin colistin with loperamide, a rifamycin, or a macrolide.

Abstract: The present invention relates to the field of therapeutics and, more in particular, to pharmaceutical compositions for the prevention and/or treatment of bacterial infections and antibacterial-induced dysfunctions. The invention is based on the identification of compounds that prevent antibacterial effects of antibiotics on microbiome-bacterial species, while retaining antibacterial effects of antibiotics on pathogenic bacteria. The invention also pertains to pharmaceutical compositions comprising antibiotics and antibiotic antidotes for the protection of commensal microbiome-bacteria. Thus, this invention relates to compounds and pharmaceutical combinations useful to prevent antibiotic-induced adverse effects on the gut microbiome. Furthermore provided are methods for preventing an adverse effect on a gut microbiome using the compounds and/or pharmaceutical compositions of this invention.
