The thio, thio acetyl, oxime, and several hydrazone and azine derivatives of the antitumor alkaloid acronycine (1) were prepared. NMR spectroscopy was used to study the configurations around the C=N double bond in these acronycine derivatives. In the hydrazones and azines of acronycine the N-N bond assumes a syn configuration to the $C_6-OCH_3$ group, while the NO bond in the oxime and the N-N bond in noracronycine hydrazone and azines assumes an anti configuration.

A series of 5-hydroxy-4-quinolone (3) and 5-methoxy-4-quinolone (4) derivatives were synthesized as truncated acridone analogues and evaluated for antitumor, antiheroes and antituberculosis activities. Among them 5-hydroxy-8-methoxy-quinolone showed potent antitumor activity ($IC_{50}$=17.7 $\mu\textrm{M}$ for HL60) which was greater than that of acronycine. However, these compounds didn't show any significant antiheroes or antituberculosis activity.
