Synthesis of fluorinated cyclopentenyladenine as potent inhibitor of S-adenosylhomocysteine hydrolase

Bioorg Med Chem Lett. 2004 May 3;14(9):2091-3. doi: 10.1016/j.bmcl.2004.02.039.

Abstract

Fluoro-DHCeA (4) was efficiently synthesized from d-cyclopentenone derivative 5 using electrophilic fluorination as a key step. Fluoro-DHCeA (4) was found to be as potent as DHCeA (3), but exhibited irreversible inhibition of enzyme unlike DHCeA (3) showing reversible inhibition. From this study, 4(')-hydroxymethyl groups of neplanocin A and fluoro-neplanocin A played an important role in binding to the active site of the enzyme.
