title: Azaprostaglandin analogues. Synthesis and biological properties of 11-azaprostaglandin derivatives.
abstract: New nitrogen analogues of prostaglandins (11, 11a, 12, and 12a) have been synthesized starting from a 4,5-disubstituted 2-pyrrolidinone nucleus (5 and 5a) containing one side chain and a suitable functionality for elaborating the second one. These analogues had no better activity than natural prostaglandins in vitro [guinea pig ileum and trachea, rat stomach fundus strip, uterus and portal vein, ADP-induced guinea pig platelet-rich plasma (PRP) aggregation]. They similarly lacked any interesting activity in vivo [anesthetized rat blood pressure, stress, and acetylsalycilic acid (ASA) induced gastric lesions in rat].
