PURPOSE:To obtain the title yarn having high modulus of elasticity and low water vapor absorption containing a specific pyrazine ring-containing aromatic group in a repeating unit. CONSTITUTION:The aimed yarn containing a repeating unit shown by formula I [Ar1 and Ar2 are bifunctional organic ...
Pyrazine is one of the important class of heterocyclic compounds that can be obtained naturally or synthesized chemically. Pyrazine ring has got importance in exhibiting various biological activities in association with other scaffolds like pyrrole, pyrazole, imidazole, triazole, tetrazole, thiophene, oxazo...
The presence of a pyrazine ring in a compound increases the interactions between the compound with the target protein. For example, the nitrogen atom can interact by hydrogen bonding, the ring offers various π-interactions and the nitrogen can form a metal bond with co-factors in the protein ...
