Abstract
Novel antifungal antibiotic compounds have the structural formula ##STR1## A preferred compound where R is 4-hydroxypentyl is denoted BU-3557B.sub.2. A complex of said compounds is produced by fermenting a culture of Sacchrothrix aerocolonigenes strain N806-4 (ATCC 53712). The complex is recovered by adsorption on nonionic porous polymer resin adsorbent and individual component compounds exhibit in vitro activity against fungi and Gram-positive bacteria and BU-3557B.sub.2 demonstrates in vitro antiprotazoal activity. BU-3557B.sub.2 demonstrates in vivo activity against C. albicans vaginal infection and BU-3557A.sub.3 (where R is 1,5-dihydroxy-5,5-dimethylpentyl) demonstrates in vivo activity against C. albicans systemic infection.
