CAS 80657-57-4: (S)-(+)-methyl B-hydroxyisobutyrate

(S)-Methyl 3-hydroxy-2-methylpropanoate

Methyl L-(S)-b-hydroxyisobutanoate is a spiroketal that belongs to the class of methyl ketones. It has been found to inhibit the growth of cancer cells in vitro and in vivo. This effect is mediated by its ability to inhibit fatty acid synthesis and its ability to activate Bafilomycin A1, which inhibits ATP synthase. Methyl L-(S)-b-hydroxyisobutanoate also has an asymmetric carbon atom at position 4, which makes it possible to synthesize stereoisomers with different biological properties. The hydroxyl group on the side chain is important for its biological function because it facilitates the binding to biomolecules.

Methyl (S)-(+)-3-hydroxy-2-methylpropionate is used as a starting material for the synthesis of dictyostatin, discodermolide and spongidepsin.
