library of compounds screened against A. calcoaceticus consisted of 1586 drugs from the
Johns Hopkins Clinical Compound Library (JHCCL) version 1.33. As previously
described by Kim et al., the drugs were prepared
with DMSO to a stock concentration of 3.3 mM in 96-well plates and
stored at −20 °C before thawing to room temperature prior
to use.30 (link)Miconazole and Dichlorophen
were identified as hits during first screening and were retested as
follows. Solid Miconazole nitrate salt was purchased from Sigma-Aldrich,
and Dichlorophen was purchased from Alfa Aesar (Ward Hill, MA, USA).
Dichlorophen structural analogues, Bithionol and Triclosan, were obtained
from Fluka Analytical and Alfa Aesar, respectively. DMSO from Amresco
was utilized as a solvent to dilute the drugs to various concentrations.
