Regioselective C‐H Thio‐ and Selenocyanation of Pyrazolo[1,5‐a]pyrimidines

Chemistry – An Asian Journal, Volume 20, Issue 9, May 2, 2025.
A metal‐free, N‐chlorosuccinimide (NCS) mediated, highly efficient, and regioselective C−H thiocyanation and C−H selenocyanation of pyrazolo[1,5‐a]pyrimidines are achieved under mild reaction conditions for the synthesis of a wide variety of 3‐thiocyanato‐ and 3‐selenocyanatopyrazolo[1,5‐a]pyrimidines in good to excellent yield up to 99 %.

Phenylpyrazolone derivatives inhibit gastric emptying in rats by a capsaicin-sensitive afferent pathway

Brazilian Journal of Medical and Biological Research, 2009
Dipyrone (Dp), 4-aminoantipyrine (AA) and antipyrine (At) administered iv and Dp administered icv delay gastric emptying (GE) in rats. The participation of capsaicin (Cps)-sensitive afferent fibers in this phenomenon was evaluated.

Novel Treatment Strategy for Patients With Urea Cycle Disorders: Pharmacological Chaperones Enhance Enzyme Stability and Activity in Patient‐Derived Liver Disease Models

Journal of Inherited Metabolic Disease, Volume 48, Issue 3, May 2025.
ABSTRACT Urea cycle disorders (UCDs) are inherited diseases causing recurrent life‐threatening metabolic decompensations due to impaired hepatic ammonia detoxification and decreased ureagenesis. Ornithine transcarbamylase (OTC) deficiency (OTCD) is X‐linked and the most common and often fatal UCD. In male hemizygous patients, disease severity primarily

1,5-Dimethyl-4-{[(3-methyl-5-oxo-1-phenyl-4,5-dihydro-1H-pyrazol-4-ylidene)(thiophen-2-yl)methyl]amino}-2-phenyl-1H-pyrazol-3(2H)-one

Acta Crystallographica Section E, 2011
In the title compound, C26H23N5O2S, an intramolecular N—H...O interaction generates an S(6) ring. The essentially planar S(6) and pyrazole rings [maximum deviations = −0.0270 (14) and 0.0195 (15) & ...

Effect of selective β-adrenoceptor blockade and surgical resection of the celiac-superior mesenteric ganglion complex on delayed liquid gastric emptying induced by dipyrone, 4-aminoantipyrine, and antipyrine in rats

Brazilian Journal of Medical and Biological Research, 2016
There is evidence for participation of peripheral β-adrenoceptors in delayed liquid gastric emptying (GE) induced in rats by dipyrone (Dp), 4-aminoantipyrine (AA), and antipyrine (At).
