title: [Theoretical study of prostaglandin E2 conformation].
abstract: The theoretical conformational analysis of PGE2 has been performed using semiempirical approach and fixed values of the bond length and valence angles. A set of low-energy conformations was obtained for the alpha-chain and the whole PGE2 molecule. Unlike the PGE1 molecule, PGE2 alpha-chain prefers semifolded conformations. The hairpin structures with the parallel orientation of alpha- and omega-chains are the lowest-energy conformations of PGE2 conformations of PGE1 and PGE2. Sterically similar explain the similar biological activity of the two molecules.
