  • QUINOLINE DERIVATIVES FOR MODULATING DNA METHYLATION
    Publication number: 20110256092
    Abstract: 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.

  • Quinoline derivatives for modulating DNA methylation
    Patent number: 7939546
    Abstract: Quinoline derivatives, particularly 4-(4-(4-(quinolin-4-ylamino)benzamido)phenylthio)pyrrolidine-2-carboxylic acid; 3-(4-(4-(quinolin-4-ylamino)benzamido)phenylthio)pyrrolidine; N-(4-(piperidin-4-ylthio)phenyl)-4-(quinolin-4-ylamino)-benzamide; and N-(4-(piperidin-3-ylthio)phenyl)-4-(quinolin-4-ylamino)-benzamide, or a physiologically acceptable salt thereof, 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.
