Compounds having α,β-unsaturatedlactones display a variety of biological activities. Many research groups have tested both natural and unnatural α,β-unsaturatedlactones for as-yet undiscovered biological properties. We synthesized α,β-unsaturatedlactones with various substituents at the δ-position and studied their immunosuppressive effects, that is, the inhibition of Interleukin-2 (IL-2) production

compounds were tested for their inhibitory effects on secretory PLA2 belonging to the groups I, II, and III, and the activities were found to be similar in both series, irrespective of the presence or absence of the additional hemiacetal function. In addition, the PLA2 inhibitory activity increases with the increasing hydrophobic character of the side chain linked to the pyranofuranone moiety. The most active
