DMAU is characterized by the presence of two methyl groups at the 1 and 3 positions, and an amino group at the 6 position of the uracil ring. This specific arrangement of substituents significantly alters the compound’s electronic properties and its interaction with biological systems. The methyl groups can enhance lipophilicity, potentially improving the compound's ability to traverse biological membranes. The amino group, on the other hand, can establish hydrogen bonds, facilitating interactions with various biological targets.
