Evaluation of Substituted Pyrazole-Based Kinase Inhibitors in One Decade (2011–2020): Current Status and Future Prospects

Molecules, 2022
Pyrazole has been recognized as a pharmacologically important privileged scaffold whose derivatives produce almost all types of pharmacological activities and have attracted much attention in the last decades. Of the various pyrazole derivatives reported

Crystal and molecular structure of 4-fluoro-1H-pyrazole at 150 K

Acta Crystallographica Section E: Crystallographic Communications, 2023
Only two 4-halo-1H-pyrazole crystal structures are known to date (chloro and bromo, the structure of 4-iodo-1H-pyrazole has not been reported yet). The triclinic structure of 4-fluoro-1H-pyrazole, C3H3FN2 (P\overline{1}), reported here is not isomorphous

Carbamidine-substituted Pyrazoles [PDF]

Nature, 1951
THE ease with which 1-substituted pyrazoles may be converted into the free imino compounds varies with the nature of the 1-substituent and the reacting substance. Thus, 1,3,5-trimethyl pyrazole may be nitrated1 and 1-phenyl pyrazole reduced to the pyrazoline2 without loss of the N-methyl or N-phenyl groups respectively.
