ABSTRACT:
New uracil derivatives of the general formula: ##STR1## wherein R.sup.1 stands for a hydrogen atom or a grouping of the formula: ##STR2## R.sup.2 for a hydrogen atom, an alkyl group or a phenyl group and R.sup.3 for an alkyl group or a phenyl group, with the proviso that when both R.sup.1 and R.sup.2 stand for a hydrogen atom, R.sup.3 stands for a phenyl group or a straight chain alkyl group with 3.about.11 carbon atoms, that when R.sup.1 stands for a hydrogen atom and R.sup.2 for methyl group, R.sup.3 stands for an alkyl group with at least 2 carbon atoms or a phenyl group, and that when R.sup.1 stands for a hydrogen atom and R.sup.3 for methyl group, R.sup.2 stands for an alkyl group with at least 2 carbon atoms or a phenyl group. These uracil derivatives are prepared by reacting 5-fluorouracil with an .alpha.-haloalkyl carboxylate or with an aldehyde diacylate or by hydrolyzing a 1,3-bis(acyloxymethyl)-5-fluorouracil with an acid or alkali. These uracil derivatives are useful as improved anti-tumor agents especially for oral administration and injection.
