Synthesis and biological activity of esters in the trans-1,2-dihydroxy-1,2-dihydroacronycine series.
Permanganate oxidation of acronycine (1) led to keto alcohol 4 which could be reduced to trans-1,2-dihydroxy-1,2-dihydroacronycine (3) using NaBH4. Acylation of 3 afforded 12, 13, and 14. These esters (12, 13, and 14) were more potent than 1 when tested against L-1210 cells in vitro. Diacetate 12 was evaluated in vivo against murine P-388 leukemia and was markedly active at a dose 16-fold lower than acronycine itself. Comparison of these results with those recently obtained in the cis-1,2-dihydroxy-1,2-dihydroacronycine series is discussed.

Synthesis and cytotoxic activity of acronycine derivatives modified at the pyran ring.
Nitration of acronycine (1) and 6-demethoxyacronycine (3) afforded 2-nitroacronycine (2) and 2-nitro-6-demethoxyacronycine (4), respectively. Reduction of 2-nitroacronycine yielded, depending on the conditions, 2-nitro-1,2-dihydroacronycine (5), 2-oxo-1,2-dihydroacronycine oxime (7) or 2-amino-1,2-dihydroacronycine (6). This latter was readily converted into 2-dimethylamino-1,2-dihydroacronycine (8), 2-acetylamino-1,2-dihydro-acronycine (9) and 2-benzoylamino-1,2-dihydroacronycine (10). The cytotoxicity of these compounds was evaluated against L1210 leukemia cells. Compounds 2 and 7 were 300- and 10-fold more potent than acronycine in inhibiting L1210 cell proliferation, respectively. Compound 2 was devoid of antitumor activity against P388 leukemia and C38 colon adenocarcinoma.

[Synthesis and cytostatic actions of 10- and 11-nitronoracronycins, molecular variations of cytostatically active acronycine].
The syntheses of 11- and 10-nitronoracronycine (10 and 11) from 1,3-dihydroxy-10-methyl-5-nitroacridinone (7) or 1,3-dihydroxy-10-methyl-6-nitroacridinone (8), respectively, and 2-chloro-2-methyl-3-butyne are reported. In screening tests with the transplantation tumor leukemia P 388 10, 11, 7 and 1,3-dimethoxy-10-methyl-6-nitroacridinone showed cytotoxicity. 8 and 1,3-dimethoxy-10-methyl-nitroacridinone (5) proved to be inactive.
