The invention relates to the
application areas of
organic chemistry, pharmaceutical
chemistry and
medicine, and particularly discloses
hydroxamic acid. The
hydroxamic acid compound has a structure shown in Formula I, wherein R is selected from a substituted
benzene ring, a heterocyclic ring, a substituted heterocyclic ring, a benzoheterocyclic ring or a substituted benzoheterocyclic ring, wherein the substitution refers to that 1-n
hydrogen atoms on the
benzene ring, heterocyclic ring or benzoheterocyclic ring are substituted by the following groups:
halogen, amino, hydroxy, nitro, cyano, alkoxy, aminoalkyl, alkylamino, sulfoalkyl, perfluoroalkyl, perfluoroalkoxy, amido or alkoxycarbonyl. According to the invention, the
hydroxamic acid compound achieves the purpose of treating neoplastic diseases by regulating
histone deacetylase; the hydroxamic acid compound has anti-proliferation effect on
tumor cells, influences
cell cycle arrest and induces
cell apoptosis; and above all, the anti-proliferation effect on
lung cancer cell strains is obviously improved in comparison with the effect of a
positive control drug SAHA (
suberoylanilide hydroxamic acid).
