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 ...
Conversion of gel-forming crystal needles to easily processable more equant crystals Using high-shear ultralow attrition agitation: accelerated Ostwald ripening without crystal attrition
(American Chemical Society, 2019-02-01)
We demonstrate the first examples of the transformation of gel-forming crystal needles into easily processable more equant crystals by accelerated Ostwald ripening without detectable crystal attrition. Using high solution ...
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 the formation of drug-drug cocrystals and coamorphous systems of the antidiabetic drug gliclazide
(Elsevier, 2019-02-23)
The antidiabetic drug gliclazide (GLZ) has a slow absorption rate and a low bioavailability due to its poor solubility. GLZ is often prescribed along with an antihypertensive, as many diabetic patients have coexistent ...
Cytotoxicity and ROS production of novel Pt(IV) oxaliplatin derivatives with indole propionic acid
(Elsevier, 2019-04-19)
The coordination of biologically active moieties to the axial positions of Pt(IV) derivatives of Pt(II) anticancer drugs allows the co-delivery and simultaneous activation of two pro-drugs for combination therapy. Pt(IV) ...
The very different effect of water on nucleation, crystallization, and hydrate stability of zingerone and vanillate esters
(American Chemical Society, 2020-01-09)
Vanillin and vanillate esters are widely used as flavorings in the food industry, and the vanillin derivative zingerone is one of the compounds found in the spice ginger. Neither the growth of single crystals of zingerone ...
