Abstrakt: Patients receiving healthcare are at higher risk of acquiring healthcare-associated infections, which cause a significant number of illnesses and deaths. Most pathogens responsible for these infections are highly resistant to multiple antibiotics, prompting the need for discovery of new therapeutics to combat these evolved threats. We synthesized structural derivatives of (+)-puupehenone, a marine natural product, and observed growth inhibition of several clinically relevant Gram-positive bacteria, particularly Clostridioides difficile . The most potent compounds-(+)-puupehenone, 1 , 15 , 19 , and 20 -all inhibited C. difficile in the range of 2.0-4.0 μg/mL. Additionally, when present in the range of 1-8 μg/mL, a subset of active compounds-(+)-puupehenone, 1 , 6 , 15 , and 20 -greatly reduced the ability of C. difficile to produce exotoxins, which are required for disease in infected hosts. Our findings showcase a promising class of compounds for potential drug development against Gram-positive pathogens, such as C. difficile .
