The invention relates to the platinum N-heterocycle derivatives of general formula (I)
in which—R1 and/or R2 are, independently of one another, an aryl or aralkyl group, each optionally substituted, a linear or branched C1-C6 alkyl group, a monocyclic C3-C7 cycloalkyl group or a linear or branched C2-C6 alkenyl group, or else R′ is a hydrogen atom and R is a group selected from the following groups: cycloalkyl or heterocycloalkyl, which is monocyclic or bicyclic and has from 3 to 8 carbon atoms, or benzyl, which is optionally substituted, or else R and R′ form, together with NH, a C3-C8 monocyclic or bicyclic heterocycloalkyl, V is a nitrogen atom or a C—R4 radical, R3 and/or R4 are hydrogen or a phenyl group or R3 and R4 may also together form a C3-C6 alkylene radical or a C3-C6 heteroalkylene radical with one or more nitrogenous heteroatoms, it being possible for the carbon atoms of the heteroalkylene radical to be modified in the form of a carbonyl radical, and X is iodine, bromine, chlorine or a nitrato (—ONO2) group.
本发明涉及通式(I)的铂N-杂环衍生物,其中-R1和/或R2分别是芳基或芳基烷基基团,每个基团可以选择性地被取代,线性或支链状的C1-C6烷基基团,单环C3-C7环烷基基团或线性或支链状的C2-C6烯基基团,或者R′是氢原子,R是从以下基团中选择的基团:环烷基或杂环环烷基,其为单环或双环且具有3至8个碳原子,或苄基,可选择性地被取代,或者R和R′与NH一起形成C3-C8单环或双环杂环环烷基,V是氮原子或C-R4基团,R3和/或R4是氢原子或苯基,或者R3和R4也可以一起形成C3-C6烷基基团或具有一种或多种含氮杂原子的C3-C6杂烷基基团,其中杂烷基基团的碳原子可以以羰基基团的形式进行修饰,X是碘、溴、氯或硝酸根(—ONO2)基团。
