The invention relates to a synthesis method for dinoprostone (prostaglandin PGE2), and in particular a method for converting prostaglandin F (for example, PGF2 alpha) to prostaglandin E (for example, PGE2). The method comprises the following steps of: oxidizing 11-site and 15-site hydroxy-protected prostaglandin PGF2 alpha to hydroxy-protected PGE2 by environment-friendly pyridine sulphur trioxide, and then hydrolyzing and de-protecting in citric acid aqueous solution to obtain PGE2. The method has the characteristics of being green and environment-friendly, safe to operate, convenient in after-treatment, short in production cycle, low in cost, and high in productivity and purity, as well as is suitable for industrialized production.

A solid-phase immunoassay for 6-keto-Prostaglandin F1α, the stable hydrolysis product of prostacyclin (Prostaglandin I2) is disclosed. Prostacyclin, a potent vasodilator with anti-platelet and anti-proliferative properties is an effective treatment for primary pulmonary hypertension and pulmonary arterial hypertension associated with scleroderma and scleroderma-like syndrome. Levels of 6-keto-Prostaglandin F1α can be directly correlated with levels of prostacyclin. Therefore, 6-keto-Prostaglandin F1α has become the indicator of choice to measure prostacyclin levels. The single step immunoassay for 6-keto-Prostaglandin F1α uses the bioluminescent protein, aequorin as a label. Analyte-label conjugates were constructed by linking the carboxyl group of 6-keto-Prostaglandin F1α and lysine residues of aequorin by chemical conjugation methods. The binding properties of 6-keto-Prostaglandin F1α towards its antibody and the bioluminescent properties of aequorin are retained in the conjugate. The concentration of 6-keto-Prostaglandin F1α after extraction from plasma shows good correlation with the concentration of 6-keto-Prostaglandin F1α obtained without prior extraction of the same plasma sample. The assay allows the measurement of 6-keto-Prostaglandin F1α directly in plasma without any pre-treatment of the samples, which results in a much simpler method with a faster assay time.
