Ribothymidine is an endogenous methylated nucleoside found in human fluids; methylated purine bases are present in higher amounts in tumor-bearing patients compared to healthy controls.DNA hypermethylation is a common finding in malignant cells and has been explored as a therapeutic target for hypomethylating agents.

NεNεNε-Trimethyl-L-lysine is a methylated derivative of the amino acid lysine. It is a component of histone proteins a precursor of carnitine and a coenzyme of fatty acid oxidation. NεNεNε--Trimethyl-L-lysine residues are found in a number of proteins and are generated by the action of S-adenosyl-L-methionine on exposed lysine residues.
