11-deoxyProstaglandinE2 (11-deoxy PGE2) is a stable, synthetic analog of PGE2 . In contrast to PGE2 which has bronchodilation effects, 11-deoxy PGE2 is a powerful bronchoconstrictor and contracts human respiratory tract smooth muscle with potencies ranging from 5 to 30 times higher than PGF2α .
11-Deoxy-16,16-dimethyl ProstaglandinE2 (11-deoxy-16,16-dimethyl PGE2) is a stable synthetic analog of ProstaglandinE2 (PGE2), acting as an agonist for both EP2 and EP3 receptors. It effectively inhibits gastric acid secretion and ulcer formation in rats, with ED50 values of 1 mg kg and 0.021 mg kg, respectively. This compound is also 900 times more potent than Prostaglandin F2α (PGF2α) in inducing contraction of human respiratory tract smooth muscle in vitro.
