General description

4-Nitro-3-pyrazolecarboxylic acid is a pyrazole derivative. Catalytic activity of bimetallic colloids, composed of silver nanoparticles partially coated with Pd clusters, adsorbed on 4-nitro-3-pyrazolecarboxylic acid, has been investigated by Surface-enhanced Raman scattering (SERS) spectroscopy. Effects of this pyrrazole on blood flow and its palladium hydrogenation has been studied.

Application

4-Nitro-3-pyrazolecarboxylic acid may be used as a starting reagent for the synthesis of library of pyrazole derivatives, potential A3 adenosine receptor (A3AR) antagonists.

Adenosine is known to act as a neuromodulator by suppressing synaptic transmission in the central and peripheral nervous system. A(3) adenosine receptor (A(3)AR) antagonists were recently considered as potential drugs for the treatment of cardiac ischemia and inflammation diseases. To
