  • This reaction underlies the methemoglobinemia toxicity seen with alkyl nitrite exposure.supported

    Recreational use of amyl or isobutyl nitrite caused methemoglobin >10% in 3 unique episodes j.toxrep.2024.03.004

  • Alkyl nitrites are rapidly metabolized following inhalation, releasing nitric oxide (NO) in vascular smooth muscle cellssupported

    Organic nitrate action derives from metabolic conversion to NO in vascular smooth muscle pmid:1529925

  • NO activates soluble guanylate cyclase (sGC) via a heme-dependent mechanism, catalyzing the conversion of guanosine triphosphate (GTP) to cyclic guanosine monophosphate (cGMP)supported

    both activate soluble guanylate cyclase via heme-dependent mechanisms; produce cGMP accumulation in vascular smooth muscle pmid:2890446

  • NO activates soluble guanylate cyclase (sGC) via a heme-dependent mechanism, catalyzing the conversion of guanosine triphosphate (GTP) to cyclic guanosine monophosphate (cGMP)supported

  • Greig et al. confirmed in a human pharmacodynamic study that amyl nitrite inhalation reduces augmentation index and pulse wave reflection — quantitative measures of arterial stiffness — demonstrating systemic arterial vasodilation in controlled conditions.supported

    Comparison of GTN and amyl nitrite pharmacodynamic profiles as vasodilators; amyl nitrite shorter-acting than GTN; both reduce arterial augmentation index pmid:15752371
