The title compound, [Ni(C(18)H(30)FO(2)P(2))(C(3)H(4)N(2))]PF(6), was prepared by halide abstraction with TlPF(6) in the presence of CH(3)CN in CDCl(3) from the respective neutral pincer chlorido analogue followed by addition of pyrazole. The PO-C-OP pincer ligand acts in typical trans-P(2) tridentate fashion to generate a distorted square-planar nickel structure. The Ni-N(pyrazole) distance is...

The acyl pyrazole derivative (3,5-di-tert-butylphenyl)(1H-pyrazol-1-yl)methanone was prepared simply and rapidly in 86% isolated yield by means of an oxidative functionalization reaction aldehyde with pyrazole. A substoichiometric quantity 4-acetamido-2,2,6,6-tetramethylpiperidine-1-oxoammonium nitrate used as the oxidant. performed solvent-free absence a base, making it clean, green approach. ...

Cytochrome P-450 (CYP) 2J4 is a member of the recently identified CYP2J subfamily-part of the CYP superfamily-and is primarily expressed in rat small intestinal epithelium (enterocytes). Studies to determine small intestinal CYP2J4 inducibility by prototypic CYP inducers have been undertaken. Immunoblot analysis of enterocyte microsomes from rats treated with beta-naphthoflavone, dexamethasone,...

In the pyrazole mol-ecule of the title solvate, C15H13BrN4O2·C2H6OS, the dihedral angle between the benzene ring and the mean plane of the di-hydro-pyrano[2,3-c]pyrazole ring system [r.m.s deviation = 0.031 (2) Å] is 86.71 (14)°. In the crystal, the pyrazole mol-ecules are linked by N-H⋯N hydrogen bonds, forming a layer parallel to (10-1). The pyrazole and dimethyl sulfoxide mol-ecules are conn...

The aim of this review is to provide an overview of diverse pharmacological activities of pyrazole moiety. This review highlighted recent reports of antimicrobial, anticancer, ACE inhibitory, antiviral as well as antiinflammatory activities of pyrazole. The purpose of this review was to collate literature work reported by researchers on pyrazole for their varoius pharmacological activities and ...

Densely functionalized 3-(4-chlorophenyl)-5-(3-hydroxy-4-etoxyphenyl)-4,5-dihydro-1H-pyrazole-1-carboxamide was  synthesized in an expedient manner through specification and transamidation  respectively, of ester-functionalized pyrazoles. This synthetic protocol allowed for three diversifying steps in which appendages on the pyrazole scaffold were adjusted to optimize inhibition of protein kina...

Aromatic organic heterocycle containing pyrimidine scaffolds possesses two nitrogen atoms of Five-membered ring. These Pyrazole skeletons comprise various ranges of pharmacological activities such as analgesic, antipyretic, anticancer, antiviral, anti-inflammatory, antioxidants, antimicrobial, anti-diabetic, anticonvulsant, ant arrhythmic activities. Pyrazole is a multipurpose lead compound dev...

In the title compound, C(26)H(20)BN(3)O, the B atom has tetra-hedral geometry and is linked to two phenyl rings, the O atom of the hy-droxy-pyrazole ring and the N atom of the pyridinyl ring. A six-membered BOCNCN ring forms by coordination of the B atom and the pyridinyl N atom. The BOCNCN ring has an envelope conformation [dihedral angle = 36.7 (1)° between the planar ring atoms and the flap]...
