  • Patent number: 6469021
    Abstract: Non-peptide compounds that act as antagonists of the intestinal hormone glucagons-like peptide 1 (GLP-1) have a 9H-b-carboline central motif. The compounds exhibit advantageous physical, chemical and biological properties and inhibit GLP-1 peptide binding to the GLP-1 receptor and/or prevent activation of the receptor by bound GLP-1. The invention further relates to a method of inhibiting the binding of GLP-1 to the GLP-1 receptor and a method of inhibiting the activation of the GLP-1 receptor. Intermediate compounds useful for making non-peptide GLP-1 receptor antagonists are also described.
