Abstract
p-(9-Anthroyloxy)phenacyl bromide (panacyl bromide) undergoes rapid reaction with the carboxyl group of prostaglandins in the presence of N,N-diisopropylethylamine in acetonitriletetrahydrofuran (4:1). The resulting prostaglandin panacyl esters are strongly uv absorbing with a λ max at 253 nm and an ϵ of 174,280 in acetonitrile. The lower limit of detection of prostaglandins was approximately 200 pg with uv detection (254 nm) and about 30 pg with fluorescent detection (exitation 253 and emission 445 nm) using normal-phase HPLC. The reactivity of panacyl bromide with 23 prostaglandins as well as prostaglandins released by human lung tissues was investigated.
