Novel diazaanthracenes of formula (I) and (II) and wherein the dotted line i n the central ring indicates that either the central ring is aromatically unsaturated, and in this case either R3 or H is absent from the 10-position and either R4 or H is absent from the 5-position, or the central ring is saturated and R3 and H and R4 and H are present, and the corresponding 5,10- diones, N-oxides, N-halides, N-amine, salts, dimers, Diels-Alder adducts, carbene adducts and complexes with transition metal compounds display valuab le antibacterial, anticancer and antifungal properties. The compounds of formul ae (I) and (II) in which R1 and R2 are both methyl groups can be obtained by subjecting 3,5-lutidine to the effect of a strong reducing agent, for exampl e molten sodium.
