    摘要: New substances designated as DC-45-A, DC-45-B.sub.1 and DC-45-B.sub.2 and represented by the following general formula: ##STR1## wherein (i) R.sub.1 and R.sub.2 together with the carbon atom therebetween represent the group ##STR2## and R.sub.3 represents ##STR3## (designated DC-45-A); (ii) R.sub.1 represents --OH, R.sub.2 represents --CH.sub.2 OH and R.sub.3 represents ##STR4## (designated DC-45-B.sub.1); or (iii) R.sub.1 and R.sub.2 together with the carbon atom therebetween represent the group ##STR5## and R.sub.3 represents ##STR6## (designated DC-45-B.sub.2). DC-45-A, DC-45-B.sub.1 and DC-45-B.sub.2 possess antibiotic and anti-tumor activity and may be obtained by culturing a microorganism of the genus Streptomyces. Preferred strain is Streptomyces bottropensis (FERM-P No. 5219; NRRL 12051).
