| Research Abstract |
The mechanism of action of three anti-infective agents was studied. Lariatin A showed selective growth inhibition against mycobacteria. The proteins that bind to lariatin A were investigated in the lysate of Mycobacterium smegmatis, which led to the identification of MSMEG1878 protein whose function has not been reported. Cyslabdan potentiated ss-lactam imipenem activity against methicillin-resistant Staphylococcus aureus(MRSA). The proteins that bind to cyslabdan were investigated in the lysate of MRSA, which led to the identification of SAR1388, which is involved in the synthesis of the pentaglycine interpeptide bridge of the MRSA peptidoglycan. Furthermore, the docking model of viridicatumtoxin and UPP synthase was investigated in silico to elucidate the binding mode of spirohexalines.
