5-HETEROARYL SUBSTITUTED INDOLES

摘要

The present invention relates 5-heteroaryl substituted indoles having high affinity for .alpha.~1-adrenoceptors. Accordingly, the compounds of the invention are considered useful for the treatment of diseases or disorders responsive to .alpha.~1-adrenoceptor antagonists. Further, as some of the compounds are selective .alpha.~1-adrenoceptor ligands they may be particularly useful as PET or SPECT ligands.
