Growth assay and sensibility test: Drug sensitivity was assessed by monitoring the inhibition of yeast cell proliferation. Yeast was grown in 1 mL culture medium YPEth (1% yeast extract, 2% peptone, 2% ethanol) with increasing drug concentrations. Cultures were inoculated at an OD600nm of 0.2 and incubated at 28°C with vigorous shaking for three days. OD600nm were then measured.
