Mono- and bis-N-oxides of a 9-aza-anthrapyrazole derivative having two 2-(dimethylamino)ethyl appendages were prepared by using a mild oxaziridine reagent. Biochemical and cell culture assays indicate that the bis-oxide is an inactive prodrug that readily converts to the active parent molecule under hypoxic conditions that are analogous to those present within certain tumors.

2-Pyrazolin-5-ones (= tautomers to 5-hydroxypyrazols) bearing dialkylaminoyalkyl substituents at the ring nitrogen atom N-1 are prepared from the corresponding hydrazines and beta-ketoesters. Detailed NMR spectroscopic investigations (1H,
Synthesis of 9,10-anthraquinone monoalkylaminoalkylhydrazones as potential antitumor drugs

In the constant search for new compounds endowed with antitumor activity we have synthesized a series of anthraquinone hydrazones, which can be seen either as opened-cycle modified anthrapyrazoles or as chromophore-modified anthracenediones. Seven 9,10-anthraquinone monoalkylaminoalkylhydrazones (3c-i) were synthesized from 10,10-dibromoanthrone (4) and a suitable N-alkylhydrazine. The hydrazones were converted into hydrochlorides and tested for their cytotoxic activity against L1210 murine leukemia cells. Two of them possess marginal activity in vitro.

3-Aryl-7-chloro-3,4-dihydroacridine-1,9(2H,10H)-dione 1-oximes and 1-hydrazone derivatives of the formula I STR1 and their physiologically tolerated acid addition and ammonium salts are described, as is a process for their preparation. The new compounds are chemotherapeutic agents and are active against protozoa, especially malaria plasmodia.
