Total Synthesis of Prostaglandin 15d-PGJ2 and Investigation of its Effect on the Secretion of IL-6 and IL-12
摘要:
An efficient synthesis of 15-deoxy-Delta 12,14-prostaglandin J(2) (15d-PGJ(2), 1) is reported. The route described allows for diversification of the parent structure to prepare seven analogues of 1 in which the positioning of electrophilic sites is varied. These analogues were tested in SAR studies for their ability to reduce the secretion of proinflammatory cytokines. It was shown that the endocyclic enone is crucial for the bioactivity investigated and that the conjugated omega-side chain serves in a reinforcing manner.
