Ga-III Complexes as Models for the M-III Site of Purple Acid Phosphatase: Ligand Effects on the Hydrolytic Reactivity Toward Bis(2,4-dinitrophenyl) phosphate
(2010)
The effects of a series of Galli complexes with tripodal ligands on the hydrolysis rate of the activated phosphate diester bis(2,4-dinitrophenyl)phosphate (BDNPP) have been investigated. In particular, the influence of the ...
Rapid hydrolysis of phosphate monoesters by zirconium(IV) complexes in neutral solution
(2012)
Three zirconium(IV) complexes (1-3) with mono- and dinucleating tripodal ligands are reported that promote the hydrolysis of the phosphate monoesters p-nitrophenyl phosphate (NPP) and phenyl phosphate (PP) in neutral ...
Use of sublimation catalysis and polycrystalline powder templates for polymorph control of gas phase crystallization
(American Chemical Society, 2018-05-08)
In pursuit of a solvent-free green alternative to solution-based processes, we have applied the combined use of catalytic additives and polycrystalline powder templates for polymorph control of gas phase crystallization ...
A phosphate-targeted dinuclear Cu(II) complex combining major groove binding and oxidative DNA cleavage
(Oxford University Press, 2018-09-17)
Free radical generation is an inevitable consequence of aerobic existence and is implicated in a wide variety of pathological conditions including cancer, cardiovascular disease, ageing and neurodegenerative disorder. Free ...
Cocrystal forms of the BCS class IV drug sulfamethoxazole
(American Chemical Society, 2018-05-23)
Sulfamethoxazole, smz, is an antibiotic that is classified as a Biopharmaceutics Classification System (BCS) class IV, low solubility and low permeability drug. Cocrystal formation has been examined in an attempt to improve ...
Application of ball milling for highly selective mechanochemical polymorph transformations
(American Chemical Society, 2018-06-07)
Milling is an important secondary processing technique in the manufacture of pharmaceuticals, primarily used as a particle size reduction process. p-Aminobenzoic acid (PABA), m-aminobenzoic acid (MABA), o-aminobenzoic acid ...
Investigation of non-covalent interactions of metal complexes with DNA in cell-free systems
(Schweizerische Chemische Gesellschaft, 2017-03-01)
Non-covalent interactions of metallo compounds with DNA range from the simple, unspecific electrostatic binding of a positively charged metal complex to the sequence-selective recognition of DNA binding sites due to shape, ...
Application of vibrational spectroscopy to study solid-state transformations of pharmaceuticals
(2016-09-01)
Understanding the properties, stability and transformations of the solid-state forms of an active pharmaceutical ingredient (API) in the development pipeline is of crucial importance for process-development, formulation ...
