Dihydrofolate reductase (DHFR) has been confirmed to be a novel target for antibacterial drug development. In this study, we determined that a fungal metabolite from Stachybotrys sp. FN298 can inhibit the DHFR of Staphylococcus aureus. Its structure was identified as a lactone form of stachybotrydial using mass spectrometry and nuclear magnetic resonance analysis. This compound inhibited S. aureus DHFR with a half-maximal inhibitory concentration of 41 µM. It also prevented the growth of S. aureus and methicillin-resistant S. aureus (MRSA) with a minimum inhibitory concentration of 32 µg·mL−1. To our knowledge, this is the first description of a DHFR inhibitor of microbial origin. The inhibitory function of the lactone form of stachybotrydial highlights its potential for development into a new broad-spectrum antibacterial agent and as an agent against MRSA.
