Identifying potent, selective protein tyrosine phosphatase inhibitors from a library of Au(I) complexes

Therapeutic inhibition of protein tyrosine phosphatase activity is a compelling yet challenging approach to the treatment of human disease. Toward this end, a library of 40 gold complexes with the general formula R 3P-Au-Cl was screened to identify novel inhibitors of PTP activity. The most promising inhibitor obtained for the lymphoid tyrosine phosphatase LYP, (2-pyridine)(Ph2)P-Au-Cl, is one of the most potent and selective LYP inhibitors identified to date with an IC50 of 1.5 ± 0.3 muM, 10-fold selectivity for LYP over PTP-PEST, HePTP, and CD45 in vitro, and activity in cellular studies as well. 2009 American Chemical Society.

The reactant in an enzyme-catalyzed reaction is called a substrate. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction.I hope my blog about 7650-91-1 is helpful to your research., COA of Formula: C19H17P

Ladderization of polystyrene derivatives by palladium-catalyzed polymer direct arylation

Ladderization of polystyrene derivatives successfully proceeded by palladium-catalyzed polymer direct arylation in the presence of a phosphine ligand and pivalic acid using poly(2-bromostyrene) as a prepolymer, in which the polymer tacticity had little influence on the reaction efficiency. The reaction mechanism was supported by theoretical calculation in detail. The optical and thermal properties of pseudo-ladderized polystyrene suggested enhanced chain rigidity.

N-substituted 2-aminobiphenylpalladium methanesulfonate precatalysts and their use in C-C and C-N cross-couplings

A series of phosphine-ligated palladium precatalysts based on N-methyl- and N-phenyl-2-aminobiphenyl have been developed. Substitution at the nitrogen center prevents the presence of traces of aminobiphenyls that contain a free -NH2 group from contaminating cross-coupling products. These precatalysts produce N-substituted carbazoles upon activation, which cannot consume starting materials. These precatalysts were efficiently generated from 2-aminobiphenyl with minimal purification and found to be highly effective in Suzuki-Miyaura and C-N cross-coupling reactions.

A convenient and selective palladium-catalyzed aerobic oxidation of alcohols

An efficient procedure for the oxidation of primary and secondary alcohols to aldehydes and ketones, respectively, with molecular oxygen under ambient conditions has been achieved. By applying catalytic amounts of Pd(OAc) 2 in the presence of tertiary phosphine oxides (O=PR3) as ligands, a variety of substrates are selectively oxidized without formation of ester byproducts. Spectroscopic investigations and DFT calculations suggest stabilization of the active palladium(II) catalyst by phosphine oxide ligands.

TBPB-promoted metal-free synthesis of thiophosphinate/phosphonothioate by direct P-S bond coupling

An efficient method for the direct coupling of thiol/thiophenol with H-phosphine oxides or H-phosphinate esters is reported. Without using any metallic catalyst, the direct sulfur-phosphorus bond coupling reaction was promoted using tert-butyl peroxybenzoate in the presence of KI at room temperature. Consequently, thiophosphinate/phosphonothioate was produced in moderate to excellent yields.

Palladium nanoparticles-polypyrrole composite as an efficient catalyst for cyanation of aryl halides

New palladium-polypyrrole (Pd/PPy) nanocomposites have been studied in cyanation of aryl halides with K4Fe(CN)6 and showed high catalytic efficiency. Aryl iodides, bromides, and chlorides are active. The reaction can be performed both in organic solvents and in water; in the latter case, the catalyst was immobilized on graphite support. The cyanation of inactivated aryl chlorides is of special importance as only a few publications dealing with efficient cyanation of aryl chlorides are available, in which expensive and poisonous phosphine ligands and non-aqueous solvents are used. The influence of the morphology of the catalyst on its efficiency in cyanation was investigated, and it was revealed that PPy spheres of about 30 nm in diameter with palladium nanoparticles of 1.2 nm in size are more efficient than bigger polymer ones (about 60 nm in diameter). Palladium content in polypyrrole spheres does not influence the yield of nitriles.

Ligand-controlled palladium-catalyzed regiodivergent suzuki-miyaura cross-coupling of allylboronates and aryl halides

An orthogonal set of catalyst systems has been developed for the Suzuki-Miyaura coupling of 3,3-disubstituted and 3-monosubstituted allylboronates with (hetero)aryl halides. These methods allow for the highly selective preparation of either the alpha- or the gamma-isomeric coupling product.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Application In Synthesis of 2-(Dicyclohexylphosphino)-2′,4′,6′-tri-i-propyl-1,1′-biphenyl, you can also check out more blogs about564483-18-7
