ABSTRACT:
The invention provides 1,4-naphthoquinone compounds and a method for inhibiting tumor cell growth in a subject by administering such compounds. The compounds are represented by the structures: ##STR1## where R.sub.1 is lower alkyl, halogenated lower alkyl, phenyl, benzyl, phenethyl, or --(CH.sub.2).sub.m COOX where m is 2 or 3 and X is H, methyl, or ethyl; R.sub.2 is halo or NHY, where Y is hydrogen, lower alkyl, halogenated lower alkyl, hydroxylated lower alkyl, lower dialkylaminoalkyl, phenyl, benzyl, or phenethyl; R.sub.3 is lower alkyl, halogenated lower alkyl, phenyl, benzyl, phenethyl, or --(CH.sub.2).sub.m COOX, where m and X are as defined for R.sub.1 above; and R.sub.4 is hydrogen, lower alkyl, lower aminoalkyl, halogenated lower alkyl, phenyl, benzyl, or phenethyl.
