Fungal isolates, fusacandins

Antifungal dorrigocin derivatives

A compound having the structural formula ##STR1## or a pharmaceutically acceptable salts and prodrugs thereof, wherein R.sup.1 is selected from the group consisting of hydrogen and loweracyl, and R.sup.2 is selected from the group consisting of hydrogen, hydroxyl and methoxyl, as well as methods for the preparation and use thereof.

Multiple drug resistance-attenuating compounds

New antibiotics, unphenelfamycin and phenelfamycins A-D, are produced by microorganisms belonging to the genus Streptomyces. The antibiotics have antibacterial activity against gram-positive and gram-negative anaerobic organisms and are effective in improving the feed efficiency and growth rate of livestock, including poultry.
