Abstract

A dimer, trimer or tetramer of an anthracycline compound which can be obtained by directly, chemically bonding anthracycline compounds having anticancer activities to each other by an alkali treatment. A high molecular block copolymer-drug complex pharmaceutical preparation in which the high molecular block copolymer having a hydrophilic polymer segment and a hydrophobic polymer segment forms a micelle having the hydrophilic segment as its outer shell and contains in its hydrophobic inner core a dimer, trimer or tetramer of anthracycline compound alone or together with other drugs. A high molecular block copolymer-drug complex pharmaceutical preparation in which the high molecular block copolymer having a hydrophilic polymer segment and a hydrophobic polymer segment forms a micelle having the hydrophilic segment as its outer shell and contains in its hydrophobic inner core an anthracycline anticancer agent, wherein, when the pharmaceutical preparation is intravenously administered to a CDF1 mouse, the amount of the anthracycline anticancer agent in 1 ml of the mouse blood plasma after 1 hour of its administration becomes 10 (% of dose/ml) or more, provided that the amount of anthracycline anticancer agent in the administered preparation is defined as 100. The aforementioned pharmaceutical preparations have high drug effects and low toxicities.
