Uses

Used in Pharmaceutical Industry:
1-Methyl-3-phenyl-2-pyrazoline-5-one is used as a therapeutic agent for the treatment of acute ischemic stroke. It serves to mitigate cell damage and inflammation in the brain by scavenging free radicals and protecting against oxidative stress, leading to improved neurological function and reduced disability in stroke patients.

Asymmetric [3 + 3] Annulation of Copper-Allenylidenes with Pyrazolones: Synthesis of Chiral 1,4-Dihydropyrano[2,3- c]pyrazoles

The copper-catalyzed asymmetric [3 + 3] annulation of ethynyl benzoxazinanones with pyrazolones has been achieved, providing simple access to 1,4-dihydropyrano[2,3-c]pyrazole derivatives in moderate to excellent yields with excellent enantioselectivities (up to 99% ee). Compared with previous annulation reactions of copper-allenylidenes from ethynyl benzoxazinanones, the current reaction fused the three carbon atoms of the propargyl moiety into a heterocyclic framework.

Synthesis of novel Ral inhibitors: An in vitro and in vivo study

Chemical synthesis was performed to produce a series of 6-amino-1,3-disubstituted-4-phenyl-1,4-dihydro pyrano[2,3-c]pyrazole-5-carbonitrile compounds (14–57) which were characterized by1H NMR,13C NMR and LC/MS–MS. These compounds were assessed for their effect on the in vitro anchorage independent growth of human lung cancer cell line H2122 and IC50values calculated. Two of the more potent compounds, BQU057 40 and BQU082 57 also displayed a dose dependent effect on RalA and RalB activity in H2122 spheroids using the common RalBP1 pull-down assay. Mouse PK and tissue distribution studies on 40 and 57 were performed and demonstrated that parent drug was present in tumor 3.0 h post ip (50 mg/Kg) dose.

P-Toluenesulphonic acid-promoted, I2-catalysed sulphenylation of pyrazolones with aryl sulphonyl hydrazides

Aryl pyrazolone thioethers were synthesized via the I2-catalysed cross-coupling of pyrazolones with aryl sulphonyl hydrazides in the presence of p-toluenesulphonic acid, which has been proposed to promote the reaction by facilitating the decomposition of sulphonyl hydrazides. This journal is

Synthesis of new pyrazolone dyes

New azo- and bisazo-5-pyrazolone dyes have been synthesised by azo coupling of various arylamines and aryl diamines with 5-pyrazolones: 1-methyl-3-phenyl-1H-pyrazol-5(4H)-one, 1-(4-chlorophenyl)-3-isopropyl-1H- pyrazol- 5(4H)-one and 3-isopropyl-1-(4-methoxyphenyl)-1H-pyrazol-5(4H)-one, respectively. All new synthesised dyes have been characterised by FTIR, 1H, 13C NMR and UV-Vis spectral studies with GC/MS and LC/MS analyses. FTIR and 1H NMR studies confirmed the existence of azo- and hydrazo-tautomeric forms of the dyes in the solid and liquid states, respectively.
