  • Patent number: 5250564
    Abstract: Compounds are provided which are crossreactive with peptides such as those bound by G-protein-linked receptors, together with preparative and therapeutic methods therefor. The compounds have the general structure: ##STR1## wherein at least one of R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5 or R.sub.6 comprises a chemical functional group which causes the compounds to be crossreactive with the peptide of interest.
    Type: Grant
