present an inexpensive, stable, and easily available boryl radical source (BPh4Na) employed in a HalogenAtom Transfer (XAT) methodology. This mild and convenient strategy unlocks the use of not only alkyl iodides as radical precursors but also of the more challenging alkyl and aryl bromides to generate C-centered radicals. The generated radicals were further engaged in the anti-Markovnikov hydroalkylation

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.
Structure-activity relationships within a series of analogues of the histamine H1-antagonist terfenadine

A number of terfenadine derivatives including terfenadine enantiomers were synthesized and tested for histamine H-1-receptor affinity. No significant differences, in H-1 activity were found between terfenadine enantiomers. Qualitative structure-activity relationship studies identified the alpha,alpha-diphenyl-4-piperidinomethanol moiety as the pharmacophore for the H-1 activity of this group of compounds. The major role of die phenylbutanol moiety in terfenadine seems to be preventing the compound from crossing the blood-brain barrier.
