  Synthesis of Adenophostin A Analogues Conjugating an Aromatic Group at the 5‘-Position as Potent IP₃ Receptor Ligands

  摘要：

  Previous structure-activity relationship studies of adenophostin A, a potent IP3 receptor agonist, led us to design the novel adenophostin A analogues 5a-c, conjugating an aromatic group at the 5'-position to develop useful IP3 receptor ligands. The common key intermediate, a D-ribosyl alpha-D-glucoside 10 alpha, was stereoselectively synthesized by a glycosidation with the 1-sulfinylglucoside donor 11, which was conformationally restricted by a 3,4-O-cyclic diketal protecting group. After introduction of an aromatic group at the 5-position of the ribose moiety, an adenine base was stereoselectively introduced at the anomeric beta-position to form 7a-c, where the tetra-O-i-butyryl donors 9a-c were significantly more effective than the corresponding O-acetyl donor. Thus, the target compounds 5a-c were synthesized via phosphorylation of the 2', 3", and 4"-hydroxyls. The potencies of compounds 5a-c for Ca2+ release were shown to be indistinguishable from that of adenophostin A, indicating that bulky substitutions at the 5'-position of adenophostin A are well-tolerated in the receptor binding. This biological activity of 5a-c can be rationalized by molecular modeling using the ligand binding domain of the IP3 receptor.
