Sodium cyanide had no effect on 125I-melatonin binding, indicating that 125I-melatonin does not bind to the heme group.

In in vitro experiments, we assayed the effect of photon scattering on the absorption spectra of an in vitro system simulating structures of lung, which consists of test tube containing air in hematocrit tubes and red blood cell suspension with various predetermined hemoglobin concentrations.

Heme needs to be released from methemoglobin, since sodium cyanide, haptoglobin, and hemopexin inhibit the induction of these proteins.
Neutrophils can oxidize hemoglobin to methemoglobin, which can subsequently induce both heme oxygenase and ferritin.

Wavelengths of 550 nm (maximal absorbance, MA) and 540 nm (isosbestic point, IP) were employed to study cytochrome c, 600 nm (MA) and 620 nm (IP) for a pigment presumed to be cytochrome aa3, 580 nm (MA) and 570 or 542 nm (IP) to control for possible effects of hemoglobin (Hb).

In each of these cases the relaxation produced by nitroprusside was at least partially reversed by the subsequent addition of excess sodium cyanide.
Unlike cyanide, however, sulfide augmented the relaxation induced by nitroprusside, and it reversed the effects of nitric oxide hemoglobin, nitroglycerin, and nitrite.

Certain compounds that oxidize hemoglobin to methemoglobin (MHb) also protect against cyanide. 2.
The compounds were administered 15 or 60 min before an intramuscular (i.m.) challenge with a 2 x LD50 dose (5.0-5.6 mg/kg) of sodium cyanide (NaCN). 5.

6289701 Kruszyna H, Kruszyna R, Smith RP: Nitroprusside increases cyclic guanylate monophosphate concentrations during relaxation of rabbit aortic strips and both effects are antagonized by cyanide. Anesthesiology. 1982 Oct;57(4):303-8.

The authors have confirmed previous observations that sodium cyanide (CN-) partially reverses the vasodilator effects of sodium nitroprusside (SNP) on vascular smooth muscle.
The ED50 values for relaxation of aortic strips for a series of directly acting agonists ("nitric oxide vasodilators") were: sodium azide (N-3) 2.1 X 10 (-7) M; SNP 2.7 X 10 (-7) M; hydroxylamine (H2NOH) hydrochloride 2.5 X 10 (-6) M; human nitric oxide hemoglobin (HbNO) 3.5 X 10 (-6) M; and sodium nitrite (NO-2) 1.2 X 10 (-4) M.

The inhibitory effect was blocked by reduced hemoglobin.
NO-CYS and SNP, like iodoacetic acid and sodium cyanide, decreased the ATP content in cortical synaptosomes, but the effect on ATP content was not related to that on [3H] 5-HT uptake.

Hypothesized to be the result of oxidation and subsequent reduction of flavoproteins, blocking mitochondrial respiration with sodium cyanide or inactivation of flavoproteins with diphenyleneiodonium substantially reduced the optical signal.
