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...

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,...

Accumulating evidence suggests that deposition of neurotoxic α-synuclein aggregates in the brain during the development of neurodegenerative diseases like Parkinson's disease can be curbed by anti-aggregation strategies that either disrupt or eliminate toxic aggregates. Curcumin, a dietary polyphenol exhibits anti-amyloid activity but the use of this polyphenol is limited owing to its instabili...

derivatives (Fig. 1) that showed in vitro and in vivo antitumor activity. These compounds were also found to inhibit tubulin polymerization as a mechanism of their action in cells. To investigate the possibilities for modification of this scaffold, we divided the moieties into five parts from A to E as shown in Fig. 1. So far, it has been reported that the length of the three carbon chain on mo...

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...

Despite the fact that this system is weakly represented in nature [1÷5], the pyrazole is well-known pharmacophore [6] and plays important role for broad-spectrum drugs. The derivatives containing pyrazole structure belong to group of antibiotics used against viral families containing RNA or DNA genome, such as e.g. HIV. Moreover, they are used as analgesic and anti-inflammatory drugs [1] and al...

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...
