MIC values of chevalone E (3) in combination with oxacillin or ampicillin, and the respective FIC index obtained against a MRSA (S. aureus B1) using the checkerboard method.

Strain MIC (µg/mL)
S. aureus B1 3 alone OX alone 3 with OX OX with 3 FIC index
˃1024 128 64 16 ˂0.188 *
S. aureus B1 3 alone AMP alone 3 with AMP AMP with 3 FIC index
˃1024 128 ˃512 128 ˃1.5

* FIC index < 0.5 indicates synergy.
