2-Amino-4-methyl-Quinoline-3-carbonitrile is a potent antitumor drug that belongs to the class of quinolines. It inhibits DNA synthesis and protein synthesis, leading to cell death. 2-Amino-4-methyl-Quinoline-3-carbonitrile has been shown to be effective against a number of cancer cell lines, including human breast cancer cells and leukemia cells. The pharmacological activity of this compound may be due to its ability to form formic acid and nitrous oxide in vivo, which can lead to DNA damage and inhibition of protein synthesis. This drug also has a high degree of homology with other quinolines, such as chloroquine, which have been used as an antimalarial agent for decades.
