摘要: Substantially pure compounds having the general formula ##STR1## wherein (1) ##STR2## R.sup.2 is .beta.-hydroxy and R.sup.3 and R.sup.4 together form an oxygen bridge, or (2) ##STR3## R.sup.2 and R.sup.3 together form an additional carbon-carbon bond, and R.sup.4 is hydroxy, are disclosed. These compounds exhibit antileukemic activity against P388 lymphocytic leukemia in CDF.sub.1 mice and inhibitory activity in vitro against cells derived from human epidermoid carcinoma of the nasopharynx(KB) cells.
