The major pathway of histidine metabolism in animals and bacteria other than incorporation into protein involves first deamination to urocanic acid, then the anaerobic addition of water to form an intermediate generally considered to be 4(5)imidazolone-5(4)-propionic acid (1, 2). Finally, the ring is split enzymatically to ~formiminoglutamic acid (3) which is converted to free cglutamic acid by...

N,N-bis(2-quinolinylmethyl)benzylamine (1) was synthesized under basic conditions from a pseudo-three-component reaction between benzylamine and two molecules of 2-(quinolinylmethyl)chloride, resulting in the formation N–C bonds single step. Compound crystallizes triclinic system P-1 space group. The unit cell comprises dimer 1, which monomers are linked by complementary hydrogen N1 H′1–C′1 ano...

In this study, we explore an a new crosslinker (bis-butyl succinate, BBS) with terminal alkyne group to react glycidyl azide polymer-based polyurethane (original PU) via “azide-alkyne” click reaction, which has supported enhancing mechanical properties and cross-link densities of modified PUs BBS. Besides, been designed synthesized successfully esterification reaction can incorporate the origin...
