S-Farnesyl thioacetic acid is an analog of S-farnesyl cysteine which behaves as a competitive inhibitor of isoprenylated protein methyltransferase (also known as S-adenosylmethionine-dependent methyltransferase). It can also inhibit methylation of both farnesylated and geranylgeranylated substrates.

N-acetyl-S-geranylgeranyl-L-Cysteine is a synthetic substrate for the isoprenylated protein methyltransferase (also known as S-adenosylmethionine-dependent methyltransferase). Because it is able to serve as a substrate for the methyltransferase, it effectively functions as an inhibitor of methylation of endogenous isoprenylated proteins.

S-Adenosylhomocysteine (SAH) hydrolase is responsible for the reversible hydrolysis of SAH into adenosine and homocysteine. Inhibition of this enzyme leads to the accumulation of SAH within cells, thereby increasing the SAH to S-adenosylmethionine (SAM) ratio and subsequently inhibiting SAM-dependent methyltransferases.
