PZ can coordinate through the
pyrazine ring nitrogen and its strong hydrogen bonding ability along with its ability to act as ligand in multiple complexes with transition metals makes it a potential candidate for the synthesis of various highly organized and distinct coordination polymers [16-19].

Pt distances belong to the shortest within the platinum(II) complexes with
pyrazine and related ligands [71].
The HOMA indices calculated for pyrrole (1), 3,4-dihydropyrrolopyrazinones (1a-c),
pyrazine (1d), 2-oxopyrazine (1e), and pyrrolopyrazinones (2-22) are shown in Table 1.
In the present study, heterocyclic compounds were also identified, including 9
pyrazines and 1 furan.
Other substances, such as menthol (42.9 per cent of samples), ethyl vanillin (16.5 per cent of samples) and acetyl
pyrazine (8.2 per cent of samples), are classified as "able to cause respiratory irritation".
No

1) was discovered by chemical modification of a
pyrazine analog initially screened by in vitro anti-influenza virus activity in cells.
Another active compound tetramethyl
pyrazine (TMP) is isolated from a Chinese herb and is capable of reversing high glucose-induced endothelial dysfunction via upregulation of Sirt1 [22].
