Abstract A series of imidazole derivatives were synthesized from two-component condensation reaction of phenylgloxal monohydrate with guanylhydrazone. They were characterized by spectroscopic and analytical techniques. The in vitro anticancer evaluation of these compounds was done on human breast cancer (MCF-7) and human liver cancer (HepG2) cell lines using the MTT assay method. Most of the newly

Quinoline derivatives, particularly 4-anilinoquinoline derivatives, are provided. Such quinoline derivatives can be used for modulation of DNA methylation, such as effective inhibition of methylation of cytosine at the C-5 position, for example via selective inhibition of DNA methyltransferase DNMT1. Methods for synthesizing numerous 4-anilinoquinoline derivatives and for modulating DNA methylation are provided. Also provided are methods for formulating and administering these compounds or compositions to treat conditions such as cancer and hematological disorders.
