摘要:
A range of novel benzopyrans have been synthesised and biologically evaluated for K-ATP channel activity employing cromakalim 1 as a benchmark K-ATP channel opener. Although the compounds that were evaluated demonstrated a reduced ability to relax phenylephrine stimulated rat thoracic tissue, we provide evidence that benzopyrans 7a-h may be operating via an alternative mechanism than ATP-sensitive K+ channel activity.
