It has been discovered that inhibiting mitochondrial respiration in platelets reduces platelet activation or platelet aggregation. Certain heterocyclic compounds significantly reduced one or more platelet functions including clumping, sticking or platelet-stimulated clotting. Thus diseases or disorders mediated by inappropriately high levels of platelet activation or platelet aggregation can be treated by administering a therapeutically effective amount of a heterocyclic compound or nonheterocyclic mitochondrial inhibitor that significantly reduces one or more platelet functions including clumping, sticking or platelet-stimulated clotting, preferably in a reversible manner.

[reaction: see text] Fused 5-heterotetrazole ring systems are synthesized in high yield via intramolecular [2 + 3] cycloadditions of organic azides and heteroatom-substituted nitriles. Cyanates, thiocyanates, and cyanamides are all competent dipolarophiles for this reaction. A variety of scaffolds are tolerated when the new enclosed ring is five- or six-membered.
