| Outline of Final Research Achievements |
It is well known that S. aureus produces a yellow pigment called staphyloxanthin. Recently, several research groups reported that staphyloxanthin is one of the important virulent factors of S. aureus and the staphyloxanthin biosynthetic pathway of S aureus could be a new potential target to combat MRSA infection. Therefor, we established the screening method and started to find the inhibitors of yellow pigment production. Under this screening, citridone A and graphiumins A to H were found as inhibitors from the culture broth of microorganisms. In the case of citridone A, a common 4,5,6a-trimethyl-4,6a-dihydro-3aH-cyclopentafuran skeleton was necessary to show biological activities.
