The development of excellent anticancer agents is a strong demand of society and an urgent matter. Anthracycline derivatives represented by adriamycin have an important position in medicine as anticancer agents due to their strong antitumor activity, and many anthracycline derivatives have been developed so far. However, these derivatives are still unsatisfactory for use in the actual treatment of cancer in relation to anticancer activity and side effects such as hair loss and myocardial toxicity. From this fact, the development of a novel anthracycline analog showing more excellent characteristic anticancer activity is strongly desired.

Test Example (Cancer Cell Proliferation Inhibitory Action) Mouse lymphocytic leukemia cultured cells (p388) were added to RPMI-1640 culture medium containing 10% fetal calf serum, and the number of cultured cells was adjusted to 5 × 10 4 cells / m. The novel 14-fluoro-4-demethoxydaunorubicin hydrochloride of the present invention was added to a predetermined concentration, and the mixture was cultured at 37 ° C for 2 days. The number of floating cells was counted using a Coulter counter, and the 50% cell growth inhibition concentration IC50 was calculated from the growth inhibition rate relative to the control group.
