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.

of metabolic degradation in most cases. The incorporation of an oxetane into an aliphatic chain can cause conformational changes favoring synclinal rather than antiplanar arrangements of the chain. Additionally spirocyclic oxetanes (e.g., 2-oxa-6-aza-spiro[3.3]heptane) bear remarkable analogies to commonly used fragments in drugdiscovery, such as morpholine, and are even able to supplant the latter

New scaffolds for drugdiscovery, 6-azaspiro[4.3]alkanes, have been synthesized in two steps from four-membered-ring ketones: cyclobutanone, thienone, N-Boc-azetidinone (Boc = tert-butoxycarbonyl), etc. The key transformation was the reaction between electron-deficient exocyclic alkenes and an in-situ generated N-benzylazomethine ylide.
