Eight esters of 2-(1-hydroxyalkyl)-1,4-dihydroxy-9,10-anthraquinone with melphalan were prepared and tested for their antitumor activity (S-180) and cytotoxicity. 2-[1-[4-(p-Bis(2-chloroethyl)-aminophenyl)-butanoyloxy]methyl]-1,4-dihydroxy-9,10-anthraquinone and 2-[1-[4-(p-bis(2-chloroethyl)-aminophenyl)-butanoyloxy]ethyl]-1,4-dihydroxy-9,10-anthraquinone showed remarkable antitumor activity (T/C,
A series of 2-alleviated anthracene-1,4,9,10-tetraone (ATO) derivatives were synthesized, and their antitumor action in ICR mice bearing S-180 cells and antiproliferative activity against L1210 cells were evaluated. Overall, the introduction of an alkyl group (CI-Cs) at C-2 enhanced the antiproliferative activity. Among 2-(1-hydroxyalkyl)- or 2-(1-acetoxyalkyl)-ATO derivatives, four compounds possessing alkyl chain of an intermediate size (G-Cs) gave T/C values of >300%. Acetylation at 1'-OH failed to cause an enhancement in the antitumor action. in contrast to a remarkable increase in antiproliferative activity. Although there was no direct relationship between antiproliferative activity and antitumor action, the compounds with lower antiproliferative activity tended to show higher antitumor activity. Further study shows that the antiproliferative activity of ATO derivatives may be explained properly neither by redox cycling nor arylating capacity.

Novel twelve esters of chlorambucil with 2-(1-hydroxyalkyl)-1,4-dihydroxy-9,10-anthraquinone were synthesized and tested for their antitumor activity in mice bearing S-180 ascitic cells as well as cytotoxic activity against L1210 cells. Eight of them were highly cytotoxic on L1210 cells (ED50, <6 g mL(-1)) and derivatives 1 and 12 (T/C, 200 and 205%) appeared more active in vivo than chlorambucil (T/C, 168%).

skeleton through a simple yet efficient transformation, which could be potentially useful for the drug discovery process. We describe herein a simple and efficient method to derivatize 1,4-dihydroxyanthraquinone by using a modifiedMarschalkreaction. This method provides a clear advantage over traditional approaches, which often require the protection and deprotection of the OH groups. We also demonstrate
