There are disclosed anthracene-9,10- bis- carbonyl- lydrazones and derivatives thereof useful for inhibiting the growth of transplanted mouse tumors, and for inducing the regression and/or palliation of leukemia and related cancers.
The compounds can be represented by the formula:
wherein Z is a trivalent moiety selected from the group consisting of those of the formulae:
wherein n is 0, 1, 2 or 3 and R is hydrogen, lower alkyl, cycloalkyl, phenyl or benzyl; R1 is of hydrogen or lower alkyl; R2 is selected from the group consisting of monovalent moieties of the formulae:
wherein p is 1, 2 or 3, q is 0, 1 or 2, R' is hydrogen or lower alkyl, R" is lower alkyl R7 is a moiety of the formula:
wherein m is 2, 3, 4 or 5, R1, R' and R" are as hereinbefore defined and the moiety -NR'R" may be pyrrolidino, piperidino, morpholino or N-methylpiperazino, X isoxo (O=), thioxo (S=) or imino (R'-N=) wherein R' is as hereinbefore defined), and R3, R4, R5 and R6 are each individually selected from the group consisting of hydrogen, halogen, hydroxy, nitro, amino, sulfonamido, lower alkyl; and the pharmacologically acceptable acid-addition and quaternary ammonium salts thereof.
These compunds can be prepared by reaction of 9,10- anthracenedialdehyde with a hydrazine. The dialdehyde is obtained from the reaction of anthracene with paraformaldehyde and hydrochloric acid, giving the 9,10-bis-(chloromethyl)anthracene derivative, which then is treated with sodium in ethanol. Or anthracene can be reacted with vinylene carbonate, to give a cyclic carbonate which is hydrol- ised to the diol, which in turn is treated with lead tetraacetate in acetic acid to give the 9,10-anthracenedicarboxaldehyde. Or 9,10-anthracenediacetonitrile, a substituted hydrazine hyrochloride, sodium acetate and Raney nickel is reduced with hydrogen to give the anthracene bis-hydrazone.

这些化合物可由式表示:
其中 Z 是三价分子,选自由下列式子组成的组
其中 n 为 0、1、2 或 3,R 为氢、低级烷基、环烷基、苯基或苄基;R1 为氢或低级烷基;R2 选自由下列式子组成的组
其中 p 是 1、2 或 3,q 是 0、1 或 2,R' 是氢或低级烷基,R" 是低级烷基 R7 是式中的分子:
其中 m 是 2、3、4 或 5,R1、R' 和 R" 如前定义,分子 -NR'R" 可以是吡咯烷基、哌啶基、吗啉基或 N-甲基哌嗪基,X 是异氧代(O=)、其中 R' 如前定义),R3、R4、R5 和 R6 各自单独选自氢、卤素、羟基、硝基、氨基、磺酰胺基、低级烷基组成的组;以及药理学上可接受的酸加成盐和季铵盐。
这些化合物可通过 9,10-蒽二醛与肼反应制备。二甲醛是由蒽与多聚甲醛和盐酸反应得到的,从而得到 9,10-双(氯甲基)蒽衍生物,然后用钠在乙醇中进行处理。或者将蒽与碳酸乙烯酯反应,生成环状碳酸酯,碳酸酯与二元醇反应生成二元醇,二元醇在乙酸中与四乙酸铅反应生成 9,10-蒽二甲醛。或者将 9,10-蒽二乙腈、取代的盐酸肼、醋酸钠和雷尼镍与氢还原,得到蒽双腙。
