New indolyl-1,3,4-oxadiazole and oxadiazinederivatives were prepared as reversible monoamineoxidaseinhibitors. The compound 5-(3-methylindolyl)-1,3,4-oxadiazol-2(3H)one was shown to be a good monoamineoxidase B inhibitor.

Non-peptide compounds comprising a central hydrazide motif and methods for the synthesis thereof. The compounds act to antagonize the action of the glucagon peptide hormone.
High throughput screening of our small molecule combinatorial library identified a class of benzoylnaphthalenehydrazones with modest affinity for the human glucagon receptor. Optimization of this initial hit through a series of targeted libraries and traditional medicinal chemistry led to ligands with nanomolar affinities. Pharmacological evaluation demonstrated that these ligands were competitive glucagon receptor antagonists. Intravenous administration of a representative benzoylnaphthalenehydrazone into rats attenuated glucagon-stimulated glucose levels.
