Usage

Chemical Properties

Benzyltriphenylphosphonium Chloride is a white to off white powder, It is highly soluble in water and polarizable solvents. It is a quaternary phosphonium salt mainly used in organic synthesis as a wittig reagent and as a phase transfer catalyst in the production of fluoroelastomers and printing inks.

Uses

Benzyltriphenylphosphonium Chloride was used as a reagent in the organic synthesis of several compounds including that of stabilised phosphonium ylides containing saturated oxygen heterocycles. Also used in the synthesis of novel substituted cis-stilbene derivatives which display antimicrobial activity.

Application

Benzyltriphenylphosphonium chloride can be used as a reactant for the synthesis of:Platinum chloro-tetrazole complexes via azidation.Trans-stilbenes and cinnamates via Wittig olefination.Achiral N-hydroxyformamide inhibitors of ADAM-TS4 and ADAM-TS5 for osteoarthritis treatment.Pentiptycenes for use as light-driven molecular brakes.Archipelago structures for formation of petroleum asphaltenes.It is also used as a crosslinking agent for tube-like natural halloysite / fluorelastomer nanocomposites.Crosslinking agent for tube-like natural halloysite / fluorelastomer nanocompositesReactant for synthesis of:Platinum chloro tetrazole complexes via azidationTrans-stilbenes and cinnamates via Wittig olefinationAchiral N-hydroxyformamide inhibitors of ADAM-TS4 and ADAM-TS5 for osteoarthritis treatmentPentiptycenes for use as light-driven molecular brakesReactant for formation of archipelago structures for formation of petroleum asphaltenes

Arylmethyloxyphenyl derivatives: Small molecules displaying P-glycoprotein inhibition

Some arylmethyloxyphenyl derivatives were prepared as simplified structures of analogous arylpiperazines with high affinity toward dopaminergic D 2 and serotonergic 5-HT1A receptors and inhibiting P-glycoprotein (P-gp). The compounds 5b and 8b displayed good P-gp inhibition activity measured as [3H]vinblastine transport inhibition in the Caco-2 cell monolayer and intracellular doxorubicin accumulation in MCF7/Adr cells by flow cytometry. Compounds 5b and 8b also inhibited, dose-dependently, ATP-ase activation induced by P-gp substrate vinblastine.

Structure-Activity-Relationship-Aided Design and Synthesis of xCT Antiporter Inhibitors

The xCT antiporter is a cell membrane protein involved in active counter-transportation of glutamate (outflux) with cystine (influx) over the human cell membrane. This feature makes the xCT antiporter a crucial element of the biosynthesis of the vital free radical scavenger glutathione. The prodrug sulfasalazine, a medication for the treatment of ulcerative colitis, was previously proven to inhibit the xCT antiporter. Starting from sulfasalazine, a molecular scaffold jumping followed by SAR-assisted design and synthesis provided a series of styryl hydroxy-benzoic acid analogues that were biologically tested in vitro for their ability to decrease intracellular glutathione levels using four different cancer cell lines: A172 (glioma), A375 (melanoma), U87 (glioma) and MCF7 (breast carcinoma). Depletion of glutathione levels varied among the compounds as well as among the cell lines. Flow cytometry using propidium iodide and the annexin V marker demonstrated minimal toxicity in normal human astrocytes for a promising candidate molecule (E)-5-(2-([1,1′-biphenyl]-4-yl)vinyl)-2-hydroxybenzoic acid.
