    摘要: Anthracycline glycosides of the formula (I) ##STR1## wherein one of R.sub.1 and R.sub.2 is hydrogen and the other of R.sub.1 and R.sub.2 is hydroxy, each of R.sub.3, R.sub.4 and R.sub.5 is independently selected from the group consisting of hydrogen and hydroxy and X is hydrogen or trifluoroacetyl, with the provisos that R.sub.4 and R.sub.5 are not simultaneously hydroxy and that if R.sub.3 is hydroxy, then X is hydrogen, which are useful in treating certain mammalian tumors are prepared by condensing an aglycone of the formula (II) ##STR2## wherein R.sub.1 and R.sub.2 are defined as above, with a suitable protected halosugar, after which the protecting groups are removed.

    摘要: Compounds having the formula: ##STR1## wherein (a) whenR.sup.1 is --COCH.sub.3 or --COCH.sub.2 OH,R.sup.2 is --OH, R.sup.3 is --OCH.sub.3 and R.sup.4 is --H;(b) whenR.sup.2 is --COCH.sub.3 or --COCH.sub.2 OH;R.sup.1 is --OH, R.sup.3 is --H and R.sup.4 is --OCH.sub.3 ;and which are useful in treating certain mammalian tumors, are prepared from 9,10-anhydro-N-trifluoroacetyl daunorubicin, a known compound. The invention described herein was made in the course of work under a grant from the United States Department of Health, Education and Welfare.
