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,

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-[1-(2-Benzoxazolyl)hydrazino]propanenitrile derivatives were evaluated in the dermal and pleural reverse passive Arthus reactions in the rat. In the pleural test these compounds were effective in reducing exudate volume and accumulation of white blood cells. This pattern of activity was similar to that of hydrocortisone and different from that of indomethacin. The structural requirements for inhibiting the Arthus reactions were studied by systematic chemical modification of 1. These structure-activity relationship studies revealed that nitrogen 1' of the hydrazino group is essential for activity and must be electron rich, whereas chemical modifications of other sites of 1 had only a modest effect on activity.
