To investigate the efficacy of KB425796-A against micafungin-resistant fungi, further antifungal studies with an in vivo infection model will be needed.
We also identified numerous possible congeners of KB425796-A by HPLC analysis of the fermentation broth of strain 530603.
As these congeners may also possess potent antifungal activity, isolation and antifungal studies of these compounds will be reported in a succeeding paper.
