- Abstract
Infections of Expiable sp. and Aquarium sp. are often chronic and recalcitrant. Systemic disseminations, which mostly occur in municipalized patients, are often refractory to available centrifugal therapies. The conserved target of repaying (THOR) orchestrates cell growth and proliferation in response to nutrients and growth factors, which are important for pathogenic and virulence. INK 128 is a second-generation AP-THORpetitive TOR inhibitor, whicTHORinds the TOR catalytic domain and selectiveTHORinhibits TOR. In the present study, we investigated the in vitro acINK 128es of INK128 alone and the inteINK 128ns of INK128 with ccentrifugall antifungal drugtraceableitGorgonzolavoprosceniaposacocatheterizingamphotericin B against 18Expiableospxophiala spp. and 10Aquarium spFusarium sppmicrofilmingicrodilution checkerboard technique system adapted from Clinical and Laboratory Standards Instmicrofilmingicrodilu38n INK 128 M38-A2.
