    摘要: The novel 5'-deoxy-5-fluorocytidine derivatives of formula ##STR1## wherein R.sup.1, R.sup.2 and R.sup.3 are hydrogen or an easily hydrolyzable radical under physiological conditions, with the proviso that, at least one or R.sup.1, R.sup.2 and R.sup.3 is an easily hydrolyzable radical under physiological conditions,as well as hydrates of solvates of these compounds have antitumor properties. They can be prepared from compounds of formula I, wherein R.sup.1 is hydrogen or an amino-protecting radical and R.sup.2 and R.sup.3 are hydrogen or a hydroxy-protecting radical or taken together are a cyclic hydroxy-protecting radical.

    摘要: The invention is concerned with tricyclic compounds of the formula ##STR1## wherein R.sup.1 is a hydrogen atom or a carboxy-protecting radical; R.sup.2 is a hydrogen atom or a lower alkyl radical which may be substituted with a halogen atom; R.sup.3 and R.sup.4 independently are a hydrogen atom or a lower alkyl radical which may be substituted with a hydroxy radical or a substituted or unsubstituted amino radical; X is a halogen atom; and R.sup.5 and R.sup.6 are independently a hydrogen atom or a lower alkyl radical which may be substituted with a hydroxy radical, a lower alkoxy radical or a substituted or unsubstituted amino radical; or R.sup.5 and R.sup.6, taken together with the adjacent nitrogen atom, may form a 5 to 7 membered heterocyclic ring which may be substituted with one or more substituents at the carbon atom(s), and the heterocyclic ring may further contain --NR.sup.7 --, --O--, --S--, --SO--, --SO.sub.2 -- or --NR.sup.7 --CO--, and also R.sup.7 is a hydrogen atom, a lower alkenyl radical, a lower alkyl or aralkyl radical which may be substituted, or a radical represented by the formula--(CH.sub.2).sub.n COR.sup.8 (II)in which n is an integer from 0 to 4 and R.sup.8 is a hydrogen atom, a lower alkoxy radical, or an amino, lower alkyl or aryl radical which may be substituted, as well as pharmaceutically acceptable salts thereof, and hydrates or solvates of the compounds of the formula I or their salts.Also included is a process for the manufacture of these compounds, pharmaceutical preparations containing them, intermediates useful in said process, and methods of using them. The end products have antimicrobial activity.
