S-Adenosyl-L-methionine analogues of formula (I)
wherein wherein R comprises a carbon-carbon double bond, carbon-oxygen double bond, carbon-sulfur double bond, carbon-nitrogen double bond, a carbon-carbon triple bond, carbon-nitrogen triple bond or an aromatic carbocyclic or heterocyclic system in β-position to the sulfonium center,
X- is an organic or inorganic anion carrying one or more negative charges,
Z is -CR1R2-, -O-, -S- or -NR3- and
R1, R2and R3 are independently selected from H, D and C1 - C12 alkyl.

placental AdoHcy hydrolase with 4, 5, or 6 resulted in time- and concentration-dependent inactivation of the enzyme (K(i): 45 +/- 0.5, 16 +/- 1, and 15 +/- 1 microM, respectively). Compound 4 caused complete conversion of the enzyme from its E-NAD(+) to E-NADH form during the inactivation process. This indicates that 4 is a substrate for the 3'-oxidative activity of AdoHcy hydrolase (type I inhibitor)
