Abstract
A-40104 antibiotic complex, comprising active factors A, B, C, and D, produced by submerged aerobic fermentation of Clitopilus pseudo-pinsitus. Individual factors, A, B, and C have been isolated. A-40104 factor C is the known antibiotic pleuromutilin. A-40104 factors A and B are novel antibiotics related to pleuromutilin. A-40104 factor A, the major new factor, is the D-xylose acetal derivative of pleuromutilin. A-40104 factors A and B, their 19,20-dihydro derivatives and the per(C.sub.2 -C.sub.6)alkanoyl derivatives of factors A and B and of their 19,20-dihydro derivatives are active against gram-positive and gram-negative bacteria, anaerobic bacteria, and Mycoplasma.
