L-lysyl-alpha-aspartyl-l-isoleucyl-n5 -(aminocarbonyl) -L-guanine is a drug often used to treat heart disease, liver disease, diabetes and other conditions. It can enter the cell through the cell membrane through active transport routes to play a role. In addition, potassium aspartate can be used to treat hypokalemia, and iron salt can treat anemia. Aspartase prevents the proliferation of cancer cells that require aspartate, such as leukemia, and the analogue of aspartate, S-carbamoyl-cysteine, has been shown to inhibit some cancer cells in animal studies (see related literature)
