A compound is provided having the formula:
1
wherein
R
1
and R
2
are independently hydrogen, hydroxy, alkoxy or acyloxy
R
3
and R
4
are independently oxo, hydroxy or hydrogen;
one of R
5
or R
6
is -A-B and the other is hydrogen, hydroxy, alkoxy, acyloxy, a group -A-B or a group -amino-R
7
—O—Y;
the or each A is independently a spacer group having the formula -amino-R
7
—O— which is bonded to the anthracene ring via the amino group nitrogen and to B via the —O— atom
R
7
is a divalent organic radical;
B is an amino acid residue, a peptide group, or isostere thereof; and
Y is hydrogen or a capping group,
or a physiologically acceptable derivative thereof.
The compounds primarily have utility against cancers, but also have use against viruses and parasites having topoisomerases.
提供一种化合物,其化学式为:其中R1和R2分别为氢、羟基、烷氧基或酰氧基;R3和R4分别为酮基、羟基或氢;R5或R6中的一个为-A-B,另一个为氢、羟基、烷氧基、酰氧基、-A-B基团或-氨基-R7-O-Y基团;每个A独立地为具有化学式-amino-R7-O-的间隔基团,通过氨基氮原子与蒽环结合,并通过-O-原子与B结合;R7为二价有机基团;B为氨基酸残基、肽基团或其同分异构体;Y为氢或封端基团,或其生理上可接受的衍生物。这些化合物主要用于治疗癌症,同时也可用于治疗具有拓扑异构酶的病毒和寄生虫。
