Repurposing the Antihistamine Terfenadine for Antimicrobial Activity against Staphylococcus aureus
摘要:
Staphylococcus aureus is a rapidly growing health threat in the U.S., with resistance to several commonly prescribed treatments. A high-throughput screen identified the antihistamine terfenadine to possess, previously unreported, antimicrobial activity against S. aureus and other Gram-positive bacteria. In an effort to repurpose this drug, structure-activity relationship studies yielded 84 terfenadine-based analogues with several modifications providing increased activity versus S. aureus and other bacterial pathogens, including Mycobacterium tuberculosis. Mechanism of action studies revealed these compounds to exert their antibacterial effects, at least in part, through inhibition of the bacterial type II topoisomerases. This scaffold suffers from hERG liabilities which were not remedied through this round of optimization; however, given the overall improvement in activity of the set, terfenadine-based analogues provide a novel structural class of antimicrobial compounds with potential for further characterization as part of the continuing process to meet the current need for new antibiotics.

(EN) Potentiating agents which enhance the efficacy of antineoplastic agents are disclosed. The potentiating agents disclosed are $g(a)-aryl-4-substituted piperidinoalkanol derivatives such as terfenadine, 11-(4-piperi-dylidene)-5H-benzo-[5,6]-cyclohepta-[1,2-b]-pyridines such as Loratadine, and N-heterocyclyl-4-piperidinamines wherein said heterocyclic radical is an optionally substituted 1H-benzimidazol-2-yl or 3H-imidazo[4,5-$i(b)]pyridin-2-yl radical, such as astemizole.(FR) Agents de potentialisation servant à augmenter l'efficacité des agents anticancéreux. Ces agents de potentialisation sont les dérivés $g(a)-aryl-4-substitués de pipéridinoalcanol tels que la terfenadine, les 11-(4-pipéri-dylidène)-5H-benzo-[5,6]-cyclohepta-[1,2-b]-pyridines telles que la Loratadine, et les N-hétérocyclyl-4-pipéridinamines où le radical hétérocyclique est un radical 1H-benzimidazol-2-yle ou 3H-imidazo[4,5-$i(b)]pyridin-2-yle éventuellement substitué tel que l'astémizole.
