The invention relates to N.sup.4 -(substituted-oxycarbonyl)-5'-deoxy-5-fluorocytidine derivatives which are useful as an agent for treating tumors, pharmaceutical compositions including the same, a method of treating tumors and a method of preparing N.sup.4 -(substituted-oxycarbonyl)-5'-deoxy-5-fluorocytidine derivatives for treating tumors. Compounds of formula (I), ##STR1## wherein R.sup.1 is a saturated or unsaturated, straight or branched hydrocarbon radical wherein the number of carbon atoms in the longest straight chain of this hydrocarbon radical ranges from three to seven, or is a radical of the formula --(CH.sub.2)n--.sup.Y wherein Y is a cyclohexyl radical, a C.sub.1 -C.sub.4 alkoxy radical or a phenyl radical and wherein when Y is a cyclohexyl radical n is an integer from 0 to 4, and when Y is C.sub.1 -C.sub.4 alkoxy radical or a phenyl radical n is an integer from 2 to 4, and R.sup.2 is a hydrogen atom or a radical easily hydrolyzable under physiological conditions, or a hydrate or solvate thereof. Compounds of formula (I) are useful in the treatment of tumors.
A compound of formula (I), ##STR6## wherein R.sup.1 is a saturated straight or branched hydrocarbon radical wherein the number of carbon atoms in the longest straight chain of this hydrocarbon radical ranges from three to seven, or is a radical of the formula --(CH.sub.2)n--.sup.Y wherein Y is a cyclohexyl radical, a C.sub.1 -C.sub.4 alkoxy radical or a phenyl radical and wherein when Y is a cyclohexyl radical n is an integer from 0 to 4, and when Y is C.sub.1 -C.sub.4 alkoxy radical or a phenyl radical n is an integer from 2 to 4, and R.sup.2 is a hydrogen atom or a radical easily hydrolyzable under physiological conditions,
A pharmaceutical composition comprising a therapeutically effective amount of one or more compounds of formula (I) ##STR7## wherein R.sup.1 is a saturated straight or branched hydrocarbon radical wherein the number of carbon atoms in the longest straight chain of the hydrocarbon radical ranges from three to seven, or is a radical of the formula --(CH.sub.2).sub.n --Y wherein Y is a cyclohexyl radical, a C.sub.1 -C.sub.4 alkoxy radical or a phenyl radical and wherein when Y is a cyclohexyl radical n is an integer from 0 to 4 and when Y is a C.sub.1 -C.sub.4 alkoxy radical or a phenyl radical n is an integer from 2 to 4, and R.sup.2 is a hydrogen atom or a radical easily hydrolyzable under physiological conditions,
