Disclosed are compounds useful in potentiating the cytotoxic effect of chemotherapeutic agents, the compounds having the formula: ##STR1## and pharmacologically acceptable salts thereof, wherein R is --H or --[C(O)].sub.a --(CH.sub.2).sub.b --A, a is 0-1 and b is 0-6 provided that a and b are not both zero; and A is selected from the group consisting of --NR.sub.1 R.sub.2 wherein R.sub.1 and R.sub.2 are independently alkyl having 1 to 4 carbon atoms, and either or both of R.sub.1 and R.sub.2 are optionally substituted with --OH; ##STR2## wherein X and Y are independently alkylene having 1 to 4 carbon atoms, and Z is --O--, --N(R.sub.3)--, or --CH(R.sub.4)--, wherein R.sub.3 and R.sub.4 are each hydrogen or alkyl having 1 to 4 carbon atoms optionally substituted with a hydroxyl group; halide; and trihalomethyl.
本发明涉及一些化合物,这些化合物的公式为: ##STR1##以及其药理学上可接受的盐,其中R为--H或--[C(O)].sub.a --(CH.sub.2).sub.b --A,a为0-1,b为0-6,前提是a和b不同时为零;而且A选自以下组中的一种,该组包括--NR.sub.1 R.sub.2,其中R.sub.1和R.sub.2分别是具有1到4个碳原子的烷基,并且R.sub.1和R.sub.2中的任意一个或两个都可以选择性地被取代为--OH;##STR2##其中X和Y分别是具有1到4个碳原子的亚烷基,而Z是--O--,--N(R.sub.3)--或--CH(R.sub.4)--,其中R.sub.3和R.sub.4各自是氢或具有1到4个碳原子的烷基,该烷基可以选择性地被一个羟基取代;卤素;以及三卤甲基。
